Kita beberapa bulan terakhir mendengan berbagai berita tentang peluncuran ujicoba jaringan LTE di berbagai negara maupun di Indonesia, namun baru 3 operator besar dunia yang berniat untuk meluncurkan LTE secara komersial, yaitu NTT DoCoMo, Verizon Wireless dan TeliaSonera.
Ini karena biaya investasi jaringan LTE dan modemnya masih sangat mahal. Sebagai contoh, pada bulan November 2010 yang lalu operator CSL dari Hongkong menjadi operator pertama yang membangun jaringan LTE di Asia. Jaringan ini merupakan upgrade dari jaringan HSPA+ dengan menambahkan perangkat LTE, sehingga pancaran BTS dari jaringan ini ada dua radiasi, yaitu HSPA+ dan LTE dalam satu sel seluler.
Walaupun sudah ada radiasi sinyal LTE, namun ini masih dalam tahap pengembangan, sebab belum ada perangkat modem LTE yang cukup murah untuk dijual kepada pelanggan. Pada sebuah seminar LTE yang diselenggarakan oleh Nokia-Siemens Network (NSN) di Jakarta pada bulam Mei 2010 yang lalu, diberitahukan bahwa contoh modem LTE yang ada berharga US$20.000,- atau Rp 200-juta, karena memang baru diproduksi satu atau dua buah saja.
Kebutuhan akan saluran transmisi data berkecepatan tinggi di negara-negara maju maupun Indonesia memang terus meningkat, walaupun margin keuntungan para Operator Telekomunikasi makin lama makin mengecil. Sampai kapan hal ini akan diakhiri? Akankah kita harus menunggu para operator itu bangkrut?
Beberapa bulan yang lalu 3 Operator besar Indonesia mengumumkan bahwa mereka telah membangun jaringan HSPA+ dengan kecepatan transmisi puncak sebesar 42 Mbps.
Untuk ini diperlukan 2 (dua) pita 5 MHz untuk meningkatkan kecepatan transmisi dari system sebelumnya yaitu HSPA dengan kecepatan transmisi puncak sebesar 21 Mbps, dikalikan dua untuk menjadi 42 Mbps. Akibatnya tiap operator butuh 3 buah pita 5 Mhz, sebab yang satu pita 5 MHz diperlukan untuk transmis suara.
Namun saya kaget ketika seorang executive Operator menyatakan bahwa belum ada modem yang dijual bagi HSPA+. Kalaupun ada, maka harganya adalah sekitar $3.500,- atau Rp 35-juta. Siapakah diantara pelanggan Indonesia yang mampu beli, hanya untuk mendapatkan kecepatan transmisi data puncak sebesar 42 Mbps? Belum lagi kalau pelanggan yang memakai pada saat yang sama lebih dari satu (concurrent users), misalnya ada dua orang, maka otomatis kecepatan transmisinya akan turun setengahnya, atau menjadi 21 Mbps. Kalau ada 10 orang, maka kecepatannya turun menjadi 4,2 Mbps....
Karena meningkatnya kebutuhan akan kecepatan transmisi data yang tingg itu, maka para operator telekomunikasi berupaya keras untuk memenuhinya, padahal sistem WCDMA sebagai sistem Mobile generasi ke-3 (3G) itu dirancang utamanya untuk layanan Voice dan SMS. Upgrading yang dilakukan dengan sistem HSDPA, HSPA dan HSPA+ adalah untuk menampung kebutuhan akan transmisi data dari pelanggan.
Memang solusi tepat bagi kebutuhan pelanggan masa depan adalah dengan meluncurkan LTE tersebut diatas, yang berbasiskan loncatan teknologi baru, yaitu teknologi Orthogonal Frequency Division Multiple Acces (OFDMA), dimana dibutuhkan pita2 prekwensi yang saling berdekatan lokasinya, bukan yang terpisah-pisah seperti yang ada saat ini, karena implementasi LTE yang sudah siap adalah FDD-LTE (Frequency Division Domain LTE), Sedangkan untuk lokasi pita frekwensi yang terpisah-pisah seperti yang dibutuhkan Indonesia hanya bisa dilakukan oleh sistem TDD-LTE (Time Division Domain LTE) yang baru akan dibuat sekitar 2-3 tahun mnendatang. Teknologi OFDMA lebih dahulu dipakai sebagai teknologi untuk sistem WiMAX 802.16e (WiMAX versi 1.0) dan WiMAX 802.16m (WiMAX versi 2.0)
Jadi bagaimanakah sulusi yang tepat bagi Indonesia dalam menghadapi kebutuhan akan transmis data yang makin lama makin besar, dengan profit margin yang makin menipis karena mahalnya CAPEX perangkat yang diperlukan?
Tunggulah posting saya berikutnjya.

The LTE PR juggernaut is running on all cylinders, with several LTE networks already in commercial service (albeit on a limited basis), and more expected to go online before the end of this year. In fact, the 3GPP says that 22 operators will have launched LTE by year-end which is an eye-catching number, considering that this time last year, only three major operators NTT DoCoMo, Verizon Wireless and TeliaSonera had definite plans to launch LTE services before the end of 2010.
There is still plenty of skepticism about the business case for rolling out LTE that early, if only because of the paucity of devices. Voice-centric LTE handsets are still two years away, according to Ovum's consulting director for Asia Pacific, CW Cheung, making LTE a data-only proposition for those launching now.
But the rollouts are happening now, and more and more trials are being announced. Perhaps more tellingly, the discussion around LTE is shifting away from technical capabilities and data speeds (which are currently within expectations, according to LSTI) towards the practical issues of deployment, and - more to the point - how much it's going to cost operators to roll it out.
The answer will vary from cellco to cellco, of course, but one clear trend is that LTE raises some serious challenges to the old way of deploying cellular networks - i.e. macro cells with wide-area coverage. Even discounting the fact that most LTE networks will be running initially in the 2.6-GHz band, which means shorter ranges by default, LTE cells will be smaller than ever, putting a premium on cell capacity over coverage. That's already having an impact on base station design (and for the better, by most accounts) but it also potentially means a lot of extra deployment costs for cellcos - unless they deploy LTE in strategic islands.
No more macros
The reason LTE requires smaller cells, says Dr Shahram G Niri, director of global LTE/SAE strategy and solutions for NEC Europe, is that the escalating growth of mobile data usage is emphasizing the need for maximizing capacity per cell, which in the 3G world means spectrum reuse.
"Even today, 3G cells are down to a few hundred meters or even a hundred meters in some cases, when it was supposed to be kilometers," he told Wireless Asia. "That's because we're learned that of all the techniques we've come up with to increase capacity and the spectral efficiency, the biggest gains we're had was from reusing the frequency, which means we can reuse the same frequency everywhere, but that means smaller cells."
The same applies to LTE, even with the wider spectrum bands being allocated for it, he adds. "With LTE, the spectrum we have will not be enough to accommodate the growth of data traffic that we're seeing."
Bjorn Amundsen, VP and director head of mobile network coverage for Telenor, says his company has reached the same conclusion in its home country of Norway.
"Even just for 2G and 3G, in the inner circle of Oslo we have a base station every 50 to 100 meters today," he says. "Looking ahead two or three years to LTE, you'll need a base station probably in every building or every second building. That's going to be a huge cost."
Site acquisition costs
With operators - particularly the ones that blew billions on 3G ten years ago - more cost-conscious than ever when it comes to network upgrades, equipment vendors have been redesigning base stations that are smaller and cheaper, as well as cheaper to run thanks to lower power consumption. But while that's a welcome development, says Amundsen, the gear is just one part of the cost of a given site.
"The biggest issue for us in rolling out LTE isn't the cost of the base station, which is the cheapest it's ever been and getting lower and lower. The real cost to us is installing the equipment into buildings," he says. "That's not getting lower that's increasing enormously. And in Norway at least, the cost of installing power to the base station is extremely expensive if you look outside the cities, up to $100,000 per km to get the power supply to the base station."
That's why Telenor's 3G coverage covers 80% of the population but only 23% of the land area, he notes.
Adding to the cost of LTE is the fact that for most operators, it't essentially another RAN overlay, says Niri of NEC.
"Actually many of these operators are running 2G and 3G already, and now we have 4G - it's difficult enough to run two networks, let alone three," Niri says. "Previously, the common belief was that 2G would be switched off somewhere around 2010 or 2012, but with the exception of Japan, we're now being proved wrong. 2G is going to be around for a long, long time. So any third network we introduce has to be simple to run and cheap to run."
Smaller form factors
Which is why vendors like NEC are advising a different approach to LTE forget macro cells and ubiquitous coverage, and focus on key congestion areas with RAN gear tailored to the purpose.
'We're telling customers to not to do macro anymore,' Niri says. They don't need to be everywhere - that's been proved with 3G -' and a macro network can provide the coverage they need but not the capacity. You need small cells, and that means you can't use the same platform as before - you need tailored equipment that's more compact, lightweight, easy to install and easy to manage."
Those kinds of requirements are driving a new approach to base station design that takes the headaches of site acquisition into account by essentially enabling them to be installed anywhere, says Joachim Hallwachs, marketing VP for DesignArt Networks.
"LTE will require ten times more cell locations than 3G, and that can't be done with the existing cost model," he says. "Is base stations get smaller, operators will be looking to acquire sites wherever they can get them, including rooftops, traffic lights and street lamps."
Consequently, Hallwachs says, operators need low-cost installation in a commercially viable site, which means it can't require lots of construction or come with high lease costs. We're seeing distributed base stations with remote radio heads and centralized baseband units, which lowers the footprint. But it's still actively cooled, and you need a shelter for it. What you really need is extremely compact gear with minimal power consumption, passive cooling, and no need for a shelter."
Hallwachs also distinguishes between femtocells - often touted as an offload solution to help cellcos manage spectrum capacity - and carrier-class base stations creating smaller cells. "The sites we're talking about will have to be software upgradeable, support remote management, and other things not associated with femtocells."
They'll also require technologies like SON (self organizing networks) with full automation, and wireless backhaul, says Hallwachs. "Wireless backhaul will be mandatory, but line-of-sight [LOS] wireless backhaul will no longer be feasible in this rollout scenario, so you need non-LOS technology."
Actually getting the base station essentials in pole-mounted form will require squeezing all base station functionality into a single box - something that DesignArt says it's enabling with its SoC (system on a chip) solution, which not only means a smaller form factor, but also one that can run on passive cooling.
"What used to be a roomful of computer equipment now fits in my hand,"he says, holding up a smartphone. "Why can't we do the same with a base station?"
Vendors are already moving in that direction, albeit from different directions. Smaller footprints and passive cooling, for example, has been addressed by vendors developing base stations for rural areas off the main power grid with the aim of making them easier to install without the need for air-conditioned shelters.
Vendors like Alcatel-Lucent are also working towards getting base stations small enough for ad hoc installation, says Philippe Poggianti, Alcatel-Lucent's VP of LTE.
'By 2012, maybe, you will see antenna panels the size of an A3 sheet of paper and around 15cm thick that can be mounted on lampposts,' Poggianti says.
Islands of LTE
However, there's still some debate over whether all this will make LTE more expensive to roll out than operators initially imagined 'particularly given LTE's initial promise of cost savings via better spectral efficiency and the flatter all-IP architecture behind the base stations. Whatever their size or the cost of installation, more sites could add up to bigger expenses, particularly once backhaul is figured into the equation (see "Thorough planning needed for 4G backhaul," as well as this issue's feature, "Rethinking the backhaul").
Enyen Cheong, APAC marketing manager for test and measurement at JDSU, argues that the economics of LTE still make more sense when looking at the total cost of ownership. "It's not just the RAN sites, but also the flat IP architecture, Ethernet backhaul and related opex savings."
Christian Daignault, chief technology officer of CSL - which has already deployed its LTE network on top of a revamped all-IP network - insists that the business case for LTE is its opex efficiency gains in the longer term.
"If you don't deploy LTE, eventually your network will cost a lot more to run as your traffic grows,"he says.
However, CSL is also picking and choosing where to deploy LTE - which is to say, in the hot-spot areas where traffic congestion is highest, with a fallback option of Dual Cell HSPA+ (see "CSL's 4G network is ready, awaiting devices" for details).
In other words, the secret to deploying LTE cost-effectively may be to forsake the old macro model and create selective islands of LTE.
That's how Telenor is doing it, says Bjorn Amundsen. "We are actually making a business case for every single base station we are building in the cities. It's the only way we can do it."
Amundsen offers an example of how it works: "If you're a customer and you come to me and say you need indoor coverage, and your business depends on it, I would say if you sign an agreement with Telenor for 12 months or two years, or whatever, we can build that indoor station. And if you're the owner of the building I will ask for you to let me stay free of charge. If you can do that, I can build it and we can start tomorrow. If you're not the owner, I must balance it and look at the income and the cost, and if I can make money I'll do it, but if I'll lose money, I won't."

Whenever talk arises about mobile networks, it immediately turns to 4G connectivity. All the major carriers are thinking about it in one way or another and before too long, a majority of mobile customers—both consumers and enterprise users—will be accessing 4G service to surf the Web, check e-mail, perform daily tasks and much more. Simply put, the 4G evolution is under way.
Exactly what that means for the average company is something that most firms are probably thinking about. After all, Sprint has been doubling down on the technology for months now and with Verizon expecting to have 38 cities supporting its 4G service by year's end, the decision to either wait for more rollouts or access 4G now is something that businesses will make sooner rather than later. Here's why 4G is the future of the enterprise.
1. It has speed on its side
The obvious benefit of 4G is that it can potentially deliver more speed than 3G networks currently available to companies. According to Verizon, for example, its 4G network can offer speeds between 1M bps and 12M bps. That's a sizable increase over anything enterprise customers are using now to access the Web from a mobile network. And considering speed will only help companies, it seems that 4G is the way to go for most firms.
2. The carriers see value in it
It would be hard to say that 4G is the future if all the major carriers weren't behind it. After all, if Sprint were leading that charge and AT&T and Verizon didn't see value in it, few companies would care. But all the major carriers are getting behind 4G. That's important. If the carriers see value in it and they push vendors to support 4G technology in their devices, it won't be long before the enterprise benefits.
3. Build 4G and the customers will come
As noted, Verizon plans to make its 4G service available in 38 cities around the United States by the end of 2010. Going forward, that number will likely rise exponentially as the company continues to invest in the technology. That's a good thing for all stakeholders. It means that as more cities are supported, the likelihood of companies jumping on the 4G bandwagon will only increase over time.
4. It will make 3G obsolete
Most companies invest in 3G technology right now, either through their smartphone data plans or via plans available for other mobile devices. But as 4G becomes more readily available around the country, companies will have no choice but to adopt the new technology. Carriers will make 3G obsolete, and the last thing companies should want to do is stick with an out-of-date technology.
5. It's about productivity
When it comes time for a company to make a decision, productivity must play a key role. If something increases productivity and it's available for the right price, it makes sense. If not, it doesn't. 4G will likely make sense on all those fronts. With Sprint's Evo 4G, for example, the company charges customers a $10 per month "premium data add-on" in addition to the plan they choose. Considering the cheapest business option is $59.99, including minutes, that's not such a bad deal, especially considering what customers get for it.
6. High-speed mobility is the future
Years ago, having employees tied to a desktop or notebook was the standard paradigm in the enterprise. But as smartphones have become more useful and high-speed connections have become more ubiquitous, companies and their workforces have become more mobile with devices that are smaller and faster than ever. The advent of 4G will only encourage enterprises to develop more powerful mobile business applications to make their employees more productive and to connect with their highly mobile customers.
7. Apple is serious about it
Apple isn't the most enterprise-focused company in the technology industry. However, its iPhone and iPad are quickly becoming favorites of business users and companies around the world. And Apple seems very interested in 4G. In fact, Verizon Wireless told the Wall Street Journal in a recent interview that Apple has interest in the carrier's 4G network. That's important. If Apple supports the technology, it won't take long for the competition to follow.
8. There might be no choice
Eventually, there might be no choice but to deploy 4G in the enterprise. The reason why is simple: Carriers want to see their customers switch to 4G, vendors are happy with it, and most IT decision-makers see value in it. When all those elements are combined, it quickly becomes clear that migrating to 4G when it becomes available in a company's area will be an essential step forward, rather than a difficult decision to make.
9. There won't be many other viable options
As of this writing, 4G seems to be the next logical step in the availability of mobile networking. There are simply no other options currently available that can match 4G in terms of its ability to combine availability and speed. That's important for companies to consider as they determine whether 4G really is the way to go.
10. It's what's needed in the marketplace
As more and more people go mobile to perform their daily tasks, they want the ability to do more with the Web connectivity made available to them. The best connectivity option will soon become 4G. Although it's in its infancy and there are many pitfalls that it can hit along the way, it just seems that 4G can't come soon enough. And when it does become the dominant mobile service, we'll wonder why we had to work without it for so long.Labels: CSL Hongkong, Pertama luncurkan LTE
Portland, OR – Oct. 20, 2010 – The WiMAX Forum today recognizes the decision within the International Telecommunication Union (ITU) approving the “WirelessMAN-Advanced” technology of IEEE 802.16m as an IMT-Advanced technology. One year ago, the WiMAX Forum and 50 leading ecosystem players announced the endorsement of IEEE’s submission to ITU-R proposing an IEEE 802.16m-based candidate for IMT-Advanced. Today’s unanimous agreement solidifies the strong consensus that has developed around the technology, indicative of its anticipated acceptance.
The key decision, taken by ITU-R’s Working Party 5D (WP 5D) at the conclusion of its meeting of 13-20 October in Chongqing, China, followed a rigorous evaluation and consensus-building process after the introduction of detailed technical proposals in October 2009, including consideration of exhaustive evaluation reports from nine expert groups from around the world. WirelessMAN-Advanced represents a group of three proposals, of which two (one by the Administration of Japan and one by Korea’s TTA) were considered technically identical to that of IEEE. During the meeting, WP 5D accepted an offer from the three parties to have IEEE complete and submit the full detailed specification of the technology at the following WP 5D meeting in April 2011. WirelessMAN-Advanced and LTE-Advanced were the only two technologies approved for IMT-Advanced.
In parallel with the finalization of IEEE 802.16m, the WiMAX Forum and its members are working to complete the detailed specification of WiMAX Release 2, which will take advantage of the new IEEE standard and ensure that WiMAX Release 2 networks and devices will offer capabilities and efficiencies to exceed the baseline IMT-Advanced requirements. WiMAX Release 2 will incorporate these capabilities while offering improved VoIP capacity, spectral efficiency, latency, handover speed, cell range, and coverage -- with support for wider operating bandwidth in both TDD and FDD modes.
“WiMAX is a commercially proven technology with a vibrant ecosystem. Our industry is ready to make WiMAX Release 2 a strong option for networks requiring IMT-Advanced capabilities,” said Ron Resnick, president and chairman of the WiMAX Forum. “We have remained focused on bringing WiMAX Certified Release 2 networks and devices to market as quickly as possible, and today’s decision within the ITU further reinforces our confidence. This decision and the WiMAX industry’s commitment to Release 2, with all its benefits, should be of particular relevance to Indian Service Providers determining which technology options will best meet India’s broadband data requirements.”
The ITU’s IMT-Advanced requirements demand candidate technologies that will provide groundbreaking speeds, and IEEE 802.16m delivers. WirelessMAN-Advanced exceeds the requirements, offering as much as 180 Mbit/s of aggregate downlink throughput per site using a 20 MHz TDD channel in ITU’s real-world microcellular system model, with further support for nearly 2500 VoIP users per site. Depending on design goals, antenna configurations, and spectrum availability, significantly higher dates rates can be enabled.
“The IMT-Advanced requirements look to satisfy the booming mobile broadband demands of the next decade. Those farsighted requirements push technology beyond all current limits,” said Dr. Roger B. Marks, vice president for technology with the WiMAX Forum. “Fortunately, WiMAX Release 1 is built on a flexible framework that allows for the introduction of countless new innovations with maintaining legacy support. Hundreds of the world’s top technical experts have been perfecting the open IEEE 802.16m draft standard since 2006. WirelessMAN-Advanced provides the ideal technology foundation for the WiMAX Forum to quickly bring the backward-compatible WiMAX Release 2 to the market.”
The WiMAX Forum's membership base is strong, representing a thriving WiMAX ecosystem that supports nearly 600 WiMAX network deployments in 149 countries. A complete list of members is available online at www.wimaxforum.org/about/. To learn more about WiMAX Forum Certified products visit the WiMAX Forum Certified registry at www.wimaxforum.org.

November 23, 2010 – To encourage WiMAX™ growth in Indonesia, ID-WiBB, an industry-led, not-for-profit organization formed to promote national vision through the compatibility and interoperability of broadband wireless products in Indonesia, announced today the launch of an Indonesian broadband roaming facility to serve the many wireless broadband service providers throughout the region.
This will enable roaming between WiMAX and Wi-Fi and possibly future LTE operators, creating a unified 4G wireless network across the nation.
“Our goal is to encourage further wireless broadband adoption and growth of the broadband ecosystem by establishing an automatic networked ID authorization that will allow anyone – regardless of their service provider – to tap in to the benefits of wireless broadband from anywhere, at anytime,” said Kanaka Hidayat, ID-WiBB. “Today’s announcement takes us one step closer to uniting the Indonesian market under one wireless broadband umbrella.”
To date, three operators awarded WiMAX derived Wireless Broadband licenses in Indonesia have signed up to become roaming partners.
Aptilo Networks, the global leader in integrated solutions for control of billing, user services and access in wireless networks including Wi-Fi, WiMAX and LTE, has been selected by ID-WIBB to enable this multi-access roaming. The award-winning Aptilo Service Management Platform™, which will serve as a AAA proxy for the authentication, authorization and accounting of roaming users between the different WiMAX and Wi-Fi service providers. The Aptilo solution will keep track of roaming subscribers’ consumption of resources (time and/or data) in any visiting network and provide the required statistics to allow ID-WiBB to serve as a neutral accounting party. The addition of LTE support to the Aptilo platform in 2011 will expand opportunities for ID-WiBB for future revenue streams.
“Aptilo is dedicated to full compliance with wireless standards, and is unparalleled in our commitment to interoperability testing with vendors in the wireless broadband arena including WiMAX,” said Jan Sjonell, Managing Director Asia/Middle East, Aptilo Networks. “We are proud to have been selected for this important project. We look forward to working hand-in-hand with ID-WiBB in encouraging growth of the wireless broadband ecosystem in Indonesia.”

4G Americas adalah Asosiasi Perdagangan Indstri Wireless Amerika Serikat yang mengembangkan teknologi wireless dalam kerjasama yang dinamakan 3GPP (3G Partnership Project).
Asosiasi ini pada tanggal 23 Novenber 2010 mengucapkan terimakasih kepada ITU atas penetapan sistem wireless LTE-Advanced dan WirelessMAN-Advanced sebagai implementasi dari satndar sistem wireless ITU IMT-Advanced.
Dalam pertemuan pada bulan Oktober 2010, ITU Radiocommunications Sector (ITU-R) Working Party 5D, yang bertanggung jawab untuk mendefinisikan teknologi IMT-Advanced 4G global, menyelesaikan penilaian enam pengajuan calon dan mencapai tonggak sejarah dengan menentukan LTE-Advanced dan WirelessMAN-Advanced sebagai rilis pertama dari IMT-Advanced. Ratifikasi akhir dari keluarga teknologi IMT-Advanced berlangsung pada pertemuan Studi ITU-R Group pada tanggal 22 dan 23 di Jenewa, Swiss.
Masa depan yang cerah sudah terlihat bagi LTE, dimana sudah ada sembilan peluncuran resmi sistem LTE komersiil pada tahun 2010, dan 11 tambahan diharapkan sebelum akhir tahun. Lebih dari 250 perusahaan telah secara terbuka menyatakan minatnya untuk menyebarkan jaringan LTE, termasuk Greenfield, CDMA, WiMAX dan operator GSM. LTE diharapkan menjadi pilihan utama untuk jaringan OFDMA generasi mendatang pada dekade berikutnya untuk semua operator nirkabel.
Sebagai evolusi masa depan LTE, LTE-Advanced akan siap sebagai solusi unggulan standar mobile broadband 4G dari ITU yang bersangsi (ITU-sanctioned), untuk informasi, komunikasi dan hiburan. Dengan menawarkan rangkaian ecosystem lengkap dari 3G terpadu (IMT-2000) dan 4G (IMT-Advanced), keluarga teknologi 3GPP mendukung kebutuhan broadband mobile yang terus berkembang dan memperluas basis internasional ekspansi operator selular dan pelanggan mereka. IMT-Advanced menyediakan platform global untuk membangun generasi selanjutnya dari layanan mobile interaktif yang akan menyediakan akses cepat data, kemampuan roaming yang disempurnakan, unified messaging dan multimedia broadband.
"Hari ini adalah tonggak sejarah untuk mengingat untuk konektivitas mobile broadband," kata Chris Pearson, Presiden Amerika 4G. "4G Amerika dengan gembira menyambut era baru komunikasi nirkabel dan sangat senang bahwa 3GPP Release 10 dan seterusnya - LTE-Advanced - teknologi mobile broadband telah disetujui oleh ITU. Masa depan untuk teknologi mobile broadband belum pernah secerah ini untuk membantu kemajuan masyarakat di Amerika dan di seluruh dunia. "
Teknologi LTE-Advanced sekarang akan berlanjut ke tahap akhir dari proses IMT-Advanced, yang menyediakan pengembangannya pada awal tahun 2012 dari Rekomendasi ITU-R untuk menentukan standar teknis teknologi radio yang lebih terinci.
Pearson menambahkan, "Selamat kepada ITU, 4G Amerika 'anggota perusahaan dan 3GPP atas upaya besar mereka bekerja dalam membuat saat ini kenyataan."
Amerika 4G adalah Representasi Pasar Mitra 3GPP.
Mengapa dikatakan "The Future is on Mobile Broadband Wireless"?
Berdasarkan fakta yang ada di Dunia saat ini, ada 5-Milyar Pelanggan Mobile Wireless, maka masa depan pertelekomunikasian akan mengarah kepada Wireless Mobile Services, dimana banyak pelanggan akan menggunakannya untuk Mobile Broadband Wireless Access, karena akan makin banyak digelar jaringan-jaringan 3G, 3.5G (HSDPA), 3.75G (HSPA). 3.9G (HSPA+) dan kemudian jaringan-jaringan LTE yang termasuk dalam klasifikasi 4G, sebagai kelanjutan evolusi dari jaringan GSM 2G dan 2.5G yang awalnya hanya bisa dipakai untuk Telpon, SMS dan data berkecepatan rendah (GPRS). Jadi sangat jelas bahwa "The Future is on Mobile Broadband Wireless for the Next Billion Subscribers" untuk melengkapi kebutuhan telekomunikasi penduduk Dunia sampai ke jumlah 6-Billion.
Roadmap Mobile Wireless tersebut diatas adalah untuk para pengguna GSM yang berevolusi melalui kerangka UMTS (Universal Mobile Telecommunications Service) dan WCDMA (Wideband CDMA), yang merupakan varian dari Standar 3G ITU IMT-2000 (International Mobile Telecommunication-2000) yang dikembangkan oleh negara2 Eropa.
Varian lainnya dari Standar 3G ITU IMT-2000 adalah cdma2000 1x (one carrier), 1x EV-DV, 1x EV-DO, dan cdma2000 3X (3-carriers) yang dikembangkan oleh negara2 Amerika Utara, Korea dan Jepang.
Definisi 3G Broadband menurut ITU adalah kecepatan transmisi up to 2 Mbps, dengan minimal 384 kbps.
Sejak beberapa tahun terakhir ini dikembangkan pula jenis teknologi CDMA dengan sistem modulasi baru, yaitu Scaleable Orthogonal Frequency Division Multiple Acces (SOFDMA) dengan sistem antena MIMO (Multiple Input Multiple Output) yang dikenal sebagai Standar Mobile WiMAX 802.16e. Perangkat Mobile WiMAX telah banyak dioperasikan di AS, Kanada, Korea, Jepang, dan Malaysia. Para operator WiMAX menyebutnya sebagai Forth Generation Mobile Technology (4G) sebagai alat untuk promosi dagang produk baru mereka, walaupun itu menyimpang dari definisi 4G menurut ITU, yaitu kecepatan transmisi puncak sebesar 1 Gbps saat diam, dan 100 Mbps saat bergerak.
Standar-standar layanan 3G dan (4G) itulah yang saat ini mendominasi pasar layanan jasa Mobile Wireless Dunia yang jumlahnya sudah mencapai 5 Milyar perangkat ponsel. Diperkirakan oleh konsultan OVUM bahwa pada tahun 2015 jumlah pelanggan Mobile Broadband Wireless akan mencapai 3,2 Milyar orang atau 4 kali (300%) dari total pelanggan Fixed Line Broadband ( DSL/ADSL, Coax Cable, PLC dan Serat Optik) yang jumlahnya hanya 780 juta pelanggan. Dari jumlah ini, pelanggan yang menggunakan serat optik (FTTH) hanyalah sebanyak 150-juta orang saja.
Jadi kesimpulannya, "The Future is on Mobile Broadband Wireless" seperti pada judul artikel ini.
Jumlah pelanggan Mobile Broadband Wireless di Indonesia diperkirakan sudah mencapai 40 juta orang, dilihat dari hasil penjualan Smartphone di Indonesia dan jumlah pengguna Internet menurut BRTI sebanyak 45-juta, sedangkan jumlah pelanggan Fixed Wireline Broadband termasuk Serat Optik FTTH tidak lebih dari 10%-nya.
Kalau melihat kemajuan Broadband di LN yang bisa menghasilkan pertumbuhan GDP 1-2% untuk pertumbuhan Broadband 10%, namun mengapa hal ini tidak terjadi di Indonesia? Penyebabnya karena Broadband Wireless yang dihasilkannya tidak sesuai dengan spesifikasi teknisnya, malah sering kali kecepatan transmisinya sangat rendah, lelet, sehinggal membuat jengkel para penggunanya. Hasilnya tidak ada innovasi dan kreativitas penggunaan jaringan broadband sebagai enabler pertumbuhan perekonomian nasional.
Ini karena para operator harus mengejar setoran pendapatan perusahaan dengan mengabaikan mutu layanan. Yang tidak mendukung juga adalah kebjiakan Regulator yang tidak memberikan lebar pita yang cukup dan dengan tarif per MHz yang tidak terlalu mahal.
Kesalahan operator lainnya adalah tidak tersedianya jaringan Backhaul atau Backbone yang cukup untuk menampung jumlah pelanggan dari tiap BTS yang maksimal hanya dapat menampung sekitar 100-200 pelangan per BTS. Jumlah BTS-pun harus ditambah, sesuai pertumbuhan jumlah pelanggan Seluler yang saat ini sudah mencapai 160-juta pelanggan, tanpa penambahan jumlah BTS secara significant.
Jaringan Serat Optik, FTTN, dalam hal ini bisa dimanfaatkan sebagai Backhaul atau Backbone, bukan sebagai FTTH, karena biayanya masih akan sangat mahal.

Jakarta - Usai permohonan izin uji laik operasinya (ULO) ditolak, PT Berca Hardayaperkasa tetap meminta kepada Ditjen Postel agar diberi kelonggaran menggunakan tambahan kanal bandwidth 5 MHz dan 10 MHz supaya tetap bisa menggelar layanan Wimax dengan brand WiGO, tahun ini juga.
"Dengan itikad baik, kami sudah bayar biaya tahunan sebesar Rp 70 miliar. Kita harap pemerintah bisa buka mata hati dengan baik," kata Duta Subagio Sarosa, Deputy CEO Berca Global Access, kepada detikINET di Jakarta, Kamis (18/11/2010).
Penggelaran layanan data pita lebar broadband wireless access (BWA) Berca yang semula dijadwalkan beroperasi mulai akhir Oktober kemarin, molor karena dinyatakan gagal oleh pemerintah dalam pengajuan ULO di Direktorat Standardisasi Ditjen Postel.
"Kami terpaksa menolak pengajuan ULO Berca karena tidak lengkap secara
administrasi," kata Direktur Standarisasi dan Sertifikasi Ditjen Postel Azhar Hasyim beberapa waktu lalu.
Menurut Azhar, alasan penolakan ULO tersebut karena Berca tak melengkapi sarat administrasi berupa pencantuman sertifikasi perangkat yang akan digunakan. "Jika tidak ada sertifikasi, standar perangkat tidak bisa diketahui," jelasnya lebih lanjut.
Berca sendiri hingga saat ini mengaku masih belum membuat keputusan mengenai
penggunaan perangkat Wimax yang akan disediakannya untuk calon pelanggan.
"Kita lagi pelajari, 16e cocok untuk retail, 16d bisa untuk corporate. Kalau kita dipaksa pakai 16d untuk cover ritel, nggak bakalan jalan. Karena modem mahal, pasar tidak mampu absorb," jawab Duta.
Meski mengakui akan mempertimbangkan perangkat 16e, namun Duta menegaskan belum pernah membuat pernyataan telah memutuskan memilih perangka tersebut.
"Saya tidak pernah confirm bahwa saya sudah pakai produk tertentu. Saya pernah ditanya siapa saja yang di-consider, saya bilang yang punya TKDN (tingkat kandungan konten dalam negeri)-lah, ada Xirca dan Panggung," ucap dia.
Sebelumnya, Chairman Berca Group Murdaya Widyawimarta Poo menjanjikan pada Oktober layanan 4G Wimax milik perseroan akan keluar dengan merek dagang WiGO.
Rencananya WiGO akan mulai tersedia di Medan dan Balikpapan pada Oktober 2010, selanjutnya menyusul Batam dan kota-kota besar lain di Sumatra, Kalimantan, Sulawesi, Bali dan Nusa Tenggara. Namun, dengan belum diluluskannya permintaan ULO, rencana itu belum bisa terlaksana.
"Perbolehkan kita untuk bisa memilih teknologi yang kita bisa pakai. Otherwise, saya juga susah jalan. Kita mau diberi kelonggaran untuk pakai 5MHz dan 10MHz, dimana kita bisa mendapatkan perangkat yang punya roadmap jauh ke depan, harga murah," kata dia.
"Sehingga spektrum efisiensi juga tercipta di alokasi spektrum kita yang 30MHz itu. Pemerintah belum atur soal kanalisasi ini, jadi kita mohon ditambahkan," Duta menandaskan.
Berca sendiri memenangkan lisensi untuk mengoperasikan layanan BWA di frekuensi 2,3 GHz, dengan lebar pita sebesar 30MHz, yang mencakup 8 zona layanan, tersebar di sebagian besar daerah-daerah di luar Jawa, yakni Sumatera, Kalimantan, Sulawesi bagian Selatan, Bali dan Nusa Tenggara. ( rou / rns )
Ini sebuah pertanyaan yang sangat menarik, yaitu apakah sebenarnya definisi dari "Broadband" itu? Masalahnya sudah sering kita mendengar berbagai berita yang hampir selalu menyebutkan perkemabangan broadband di Indonesia maupun di dunia, tetapi definisi Broadband secara jelas masih belum ada, atau banyak yang belum tahu.
Berikut ini sebuah penjelasan yang lengkap beserta sejarah perkembangannya, bagaimana istilah itu dimunculkan untuk mengukur kinerja jaringan layanan telekomunikasi.
Technical Definition of Broadband:
Broadband refers to telecommunication that provides multiple channels of data over a single communications medium, typically using some form of frequency or wave division multiplexing.

A study of broad band and expected growth of the market.pdf |
Broadband access is a vehicle that allows the delivery of an entirely new breed of media services and communications-oriented applications. In the long run, it is these new services and applications that will differentiate broadband from dial-up Internet access and give consumers a reason for subscribing to broadband. Audio and video are the obvious cornerstones of this coming high-speed revolution. Speedy connections coupled with always-on access will improve the consumer multimedia experience and change the types of business models that are viable in the interactive marketplace. As use of broadband grows to more than 20 million subscribers by 2004, traditional media companies may uncover opportunities for growth and acquisition in these alternative content categories enabled by the high-speed Internet. Broadband will not replace traditional media formats as they exist today. But it will emerge as a new source of fragmentation, siphoning off enough listeners and viewers to affect established media entities and their long-term growth.
Federal Full broadband lines are lines with information carrying capability in excess of 200 Kbps in both directions, simultaneously. One-way broadband lines are lines with information carrying capacity in excess of 200 Kbps in one direction (typically downstream) and less than or equal to 200 Kbps in the other direction (typically upstream).

Broadband Access for Consumers is either through DSL (Digital Subscriber Lines) or via cable modem. See attached FCC Document
DSL is a technology for bringing high-speed and high-bandwidth, which is directly proportional to the amount of data transmitted or received per unit time, information to homes and small businesses over ordinary copper telephone lines already installed in hundreds of millions of homes and businesses worldwide. With DSL, consumers and businesses take advantage of having a dedicated, always-on connection to the Internet.
There are currently at least six different types of DSL. They are Asymmetric Digital Subscriber Line (ADSL), Symmetric Digital Subscriber Line (SDSL), ISDN Digital Subscriber Line (IDSL), High-bit-rate Digital Subscriber Line (HDSL), Very high-bit-rate Digital Subscriber Line (VDSL), and Rate-Adaptive Digital Subscriber Line (RADSL). Each one has different technical ranges, capabilities, and limitations.
Cable modems (CM) are designed to operate over cable TV lines to provide high-speed access to the Web or corporate Intranets. A power splitter and a new cable are usually required. The splitter divides the signal for the "old" installations and the new segment that connects the cable modem. No television sets are accepted on the new string that goes to the cable modem.
There are three types of CM: external modem, internal modem, and interactive set-top cable box. A number of different cable modem configurations are possible. Over time more systems will arrive.
Cable modem services offer shared bandwidth between your and your neighbors. Your speed will vary with how many people are on the cable modem network, which may be a disadvantage. With DSL service, you have a dedicated connection to your home.
Sebuah studi oleh Konsultan OVUM menunjukkan bahwa di 7-negara yang di-survey, yaitu India, Malaysia, Pakistan, Filipina, Rusia, Saudi Arabia, dan Afrika Selatan menunjukkan bahwa secara rata-rata bila diperhitungkan "Best Value for Money", maka layanan WiMAX masih menunjukkan keunggulannya untuk layanan data per 100 MB pada tingkat "enty-level" bila diperbandingkan layanan yang sama oleh 3.xG HSPA dan oleh layanan DSL (kalau di Indonesia adalah ADSL Speedy TELKOM).
Hasil survey ini dapat dilihat pada Tabel diatas ini.
OVUM memberikan catatan bahwa di banyak negara berkembang, tarif 3.xG HSPA maupun DSL dipasang sangat tinggi oleh para operator (incumbent) karena mereka umumnya masih memiliki hak monopoli, sehingga mereka dapat menetapkan keutungan setinggi mungkin.
Akibatnya penetrasi Broadband akan berjalan sangat lambat, sebab tarif-nya jauh diatas daya beli rakyat yang GDP-nya cukup rendah. Sebagai perbandingan, di negara-negara maju, tarif Broadband hanya berkisar sekitar 1-2% dari gaji bulanan warga biasa, sedangkan di beberapa negara berkembang, tarif Broadband mencapai lebih dari 100% gaji bulanan rakyat biasa di negeri itu. Itulah sebabnya "Digital Gap" di negara-negara berkembang makin bertambah besar saja.
Bagaimanakah perbandingan itu bagi Indonesia. Bila kita anggap WiMAX yang akhirnya dipakai Indonesia adalah WiMAX 16e seperti halnya di Malaysia dan negara-negara lain, maka harga modem USB dongle-nya adalah sekitar US$50 pada awalnya, dan akan turun ke US$30 setelah makin banyak pelanggannya. Harga ini masih sebanding dengan harga modem USB dongle HSPA Indosat M2 maupun TELKOMSEL.
Dari pengalaman di Operator WiMAX 16e P1 Malaysia, quota penggunaan data mencapai rata-rata 10GB per bulan. Oleh karena itu sebagai pembanding tarif HSPA di Indonesia dipakai tarif tertinggi IM2 sebesar Rp 900.000 per bulan seperti pada Tabel dibawah ini:
Sedangkan tarif pembanding layanan ADSL dipakai Tarif Layanan Executive Speedy TELKOM sebesar Rp 995.000 per bulan sebagaimana terlampir dibawah ini:
Keunggulan lain yang mungkin bisa diperoleh dari layanan WiMAX 16e di Indonesia dibandingkan dengan layanan HSPA maupun ADSL Speedy adalah karena sifatnya yang "best effort" maksimum 3,6 Mbps bagi HSPA dan 3 Mbps bagi Speedy, yang pada kenyataannya sering jauh dibawah angka-angka itu. Kanal WiMAX adalah dedicated untuk data, bukan bergabung dengan layanan Voice, sehingga ada kemungkinan lebih baik mutu layanannya.
Silahkan ditanggapi.

Jaringan Mobile Wireless saat ini telah berhasil menghubungkan 5 Milyar Pengguna di Dunia dari 6 Milyar Manusia. Tinggal 1-Milyar lagi manusia yang harus dihubungkan dengan Jaringan Mobile Wireless, dimana mereka umumnya adalah masyarakat dengan penghasilan yang minimal, atau dibawah garis kemiskinan yang menurut PBB nilainya adalah US$2,50 per hari (Rp 23.000 per hari) untuk sekadar cukup untuk memenuhi kebutuhan pokok makan dan minum.
Bagaimana cara atau strategi-nya untuk menambah jumlah pengguna Telpon Seluler bagi mereka-mereka yang penghasilannya sangat minim ini? Strategi-nya sudah tercantum dalam judul artikel ini, yaitu Meaningful SMS, Meaningful Internet dan Meaningful Broadband. Ini sangat jelas, sebab kalau yang dipakai bukan strategi ini, maka tiap penambahan jumlah pengguna Telpon Seluler dari kalangan miskin ini malah akan makin menambah kemiskinan mereka, mereka akan semakin kurus, sebab uang yang seharusnya mereka pakai untuk membeli kebutuhan pokok makan dan minum mereka dikurangi untuk beli pulsa Telpon Seluler.
Yang paling aman adalah dengan tidak menawarkan Layanan Telpon Seluler bagi Rakyat Miskin ini. Tetapi dampaknya adalah para Operator Telpon Seluler ini akan makin berkurang Revenue mereka, perusahaan-perusahaan itu akan makin mundur karena berkurang penghasilannya, dan akhirnya akan merugi atau bangkrut.
Strategi yang dilakukan oleh mayoritas Operator Seluler Indonesia adalah dengan memberikan imin-iming hadiah atau keuntungan kepada para pelanggan/calon pelanggan, agar mereka terus menggunakan Telpon Seluler mereka, misalnya gratis setelah 3-menit, dapat hadiah pulsa, SMS, dll, yang ujung-ujungnya para pelanggan itu terus saja membeli pulsa isi ulang dan menggunakan perangkat Telpon Seluler-nya untuk berkomunikasi dengan siapa saja, tanpa tujuan dan manfat yang kelas. Untuk yang memakai perangkat HP yang lebih canggih (Smartphone) maka mereka terus saja chatting di YM, BBM, Fecebook dan Twitter, tentang apa saja yang kira-kira akan mendapat tanggapan dari kawan-kawannya, dan memperoleh pujian (narsis).
Ini adalah sebuah strategi yang keliru, dimana strategi yang lebih tepat adalah dengan Meaningful SMS, Meaningful Internet dan Meaningful Broadband, dalam arti kata, mereka-mereka yang menggunakan SMS, Internet dan Broadband akan mendapatkan manfaat, keuntungan atau penghasilan finansial, sehingga pada akhirnya mereka bukannya tambah miskin, tetapi akan bertambah kaya, meningkatkan taraf hidup mereka.
Ini adalah hipotesa atau data empiris yang sudah banyak kita ketahui berdasarkan pengukuran di berbagai negara di dunia, yaitu pertumbuhan penetrasi jaringan Internet sebesar 10% per tahun akan menghasilkan pertumbuhan GDP kumulatif sebesar 2,6% per tahun berurutan sampai 5-tahun kedepan. Hipotesa lainnya, pertumbuhan Broadband sebesar 10% akan menghasilkan pertumbuhan GDP sebesar 1%.
Strategi yang tepat adalah strategi "meaningful" tersebut diatas, bukan asal-asalan untuk mencapai target Revenue Operator tanpa mempedulikan nasib kehidupan para pelanggan Seluler itu.
Berikut ini adalah contoh-contoh Strategi Meaningful SMS, Internet dan Broadband yang telah sukses diterapkan di beberapa negara berkembang sbb:
