Wireless Technology

In business school, where I teach, students are often predisposed to see legal concepts as impenetrable and foreign. I watch the lightbulbs go on as they see that Microsoft's antitrust woes, RIM's $600 million patent infringement settlement, and Galleon's downfall due to insider trading say as much about strategic judgment and application of analytical tools as the cases that they study in marketing, management or accounting. The most successful businesses understand the non-market environment in which they operate.
Network neutrality is another good example. Business executives should recognize that the contours of broadband Internet access will affect them, both as customers and as providers. And for all the apparent complexity, the major issues are straightforward. Those reading recent headlines might be surprised to learn just how much agreement there is today on two fundamental points: the Internet fosters innovation and investment in new business opportunities because it's an open platform, and the network operators who build onramps to the Internet thrive when they maximize the returns on their invested capital.
The Federal Communications Commission (FCC), when proposing network neutrality rules last year, emphasized both dimensions. It offered a pragmatic framework that would put the United States in line with Great Britain, Canada, Japan, and other countries that have considered the issue. It proposed a set of basic principles — no blocking or degradation of traffic or devices, no discriminatory favoritism of affiliated services, and transparency — enforced through a case-by-case process that took into account the need for reasonable network management and the legitimacy of private "managed services" alongside the public Internet.
It's not hard to see why business should favor such a regime. Venture capitalists seeking the next YouTube or Twitter want assurance that a broadband access provider won't throttle the new application to advantage its own affiliates, and those broadband providers want certainty that they can use good engineering practices to manage their networks. The FCC's proposals were designed to foster clarity on both sides.
So, where is the controversy? The problem lies with those who see a religious conflict about whether the Internet will be "discriminatory" or "regulated." The simple truth is that it will be a little of both. We regulate the financial system, health care, electricity, and every other essential infrastructure for a modern economy. Pharmaceutical companies don't put drugs into the marketplace without FDA review of clinical trials, and startups don't launch IPOs without SEC registration. The success of those regimes is a big reason for America's global economic strength.
The FCC and other regulators can do a better or a worse job. It's certainly fair to talk about how to optimize the regulatory process. And it's appropriate to call for regulators like FCC Chairman Genachowski, a former venture capitalist and e-commerce executive, who appreciate the dangers of government over-reach.
It's not appropriate to disregard what the FCC actually said. Robert Litan and Hal Singer, for example, should feel reassured by the FCC's language on the concern they raise about "enhanced services" with special traffic handling: "We recognize that these managed or specialized services may differ from broadband Internet access services in ways that recommend a different policy approach, and it may be inappropriate to apply the rules proposed here to managed or specialized services." (Open Internet NPRM, paragraph 149).
This leaves plenty of important details to address. Can Sony's packets be prioritized without degrading the Internet experience for everyone else? Would Zynga have pioneered a multi-billion dollar social gaming market if it had to pay for priority delivery from day 1 to compete with Sony? What if Sony's agreement blocks Microsoft from receiving priority delivery for its competing online gaming portal? Should AT&T's prioritization of its own online gaming portal be viewed differently? Should the same rules apply to wireless broadband? How would enforcement work?
These are not new issues. There has been continuous debate at the FCC about network neutrality for six years. The absence of a comprehensive legal framework exerts a drag on the market. And with no enforceable rules, companies from Facebook to Foursquare have no confidence that discriminatory practices won't undermine their investments. Fortunately, over time, even as the rhetoric has ratcheted up, advocates on both sides have narrowed their differences substantially.
Verizon and Google have now issued a proposal that offers compromise solutions to the major disputed elements of a network neutrality regime. It's a flawed proposal, but it's a step in the right direction if it helps to break the logjam in Washington. Businesses can help achieve that result by supporting a solution that is workable in practice for the long run. For example, if the current wireless broadband market is too immature and different for the same rules to apply, what are the triggers for that to change?
The most valuable area where business can contribute is to support giving the FCC and other agencies the flexibility they need. A recent appeals court ruling called into question the FCC's legal authority over broadband access, opening the door to more years of lawsuits and Congressional lobbying. Such prolonged uncertainty benefits no one.
The FCC was established in 1934 because in complex, fast-changing industries, a body with expertise and open, transparent decision-making processes is the best forum to resolve contentious issues. That's still true. Chairman Genachowski has already proposed to "forbear" preemptively from FCC regulation of Internet content or business practices, outside the limited open Internet rules needed to promote competition and innovation.
The FCC should have the tools to do its job, now and as the marketplace evolves. Network neutrality is just one aspect of a vibrant environment of open, interconnected networks. One would hope that the 2008 financial crisis put to rest the spurious notion that business functions best when regulation functions least.
An open Internet is one in which investment is rewarded and the best innovations win. What could be more pro-business than that?

• LTE SON leverages network intelligence, automation and network management features in order to automate the configuration and optimization of wireless networks, thereby lowering costs and improving network performance and flexibility 
• A key goal of LTE SON standardization is the support for multi-vendor network environments, which has resulted in the definition of standard messaging formats to convey information between entities that can be used to implement a given SON algorithm
• Strong operator interest in LTE SON is evident from the significant SON contributions coming from organizations such as the Next Generation Mobile Networks Alliance (NGMN), and examples of the deployment of various SON use cases by LTE operators in their respective networks
• Results from SON trials in a live HSPA network demonstrate the benefits for operators and provide further validation of the potential benefits of SON in LTE networks 

Sebuah studi yang dilakukan oleh Konsultan OVUM menunjukkan bahwa di tingkat Entry Level Broadband seperti di India, Rusia, Pakistan, Afrika Selatan dan Saudi Arabia, biaya transmisi data 100 MB melalui WiMAX hanyalah 1/100 sampai 1/10 dari biaya transmisi data melalui jaringan 3G GSM HSPA. Silahkan melihat tabel dibawah ini:

 Jadi kesimpulannya, WiMAX akan jauh lebih kompetitif dibandingkan dengan jaringan HSPA, terutama bagi Operator Baru WiMAX, seperti First Media, Berca, dan lainnya yang belum memiliki jaringan infrastruktur GSM.

Oleh karena itu perbandingan biaya antara WiMAX dan LTE di Clearwire USA tidaklah valid, sebab Clearwire adalah Operator Incumbent Amerika Serikat yang besar, seperti PT TELKOM/TELKOMSEL.

Jangan sampai terkecoh dengan judul Milis : "4G belum waktunya di Indonesia", sebab ini akan mengaburkan masalah pokok bangsa.

Permasalahan pokok pertama bangsa saat ini adalah sempitnya alokasi pita lebar yang diberikan kepada para operator GSM/CDMA Indonesia, yaitu 5 MHz atau 10 MHz. Sedangkan Clearwire meng-klaim bahwa ia adalah Operator besar di AS dengan kepemilikan Spektrum Frekwensi terbesar, sehingga mampu memberikan layanan transimisi data yang tinggi dengan biaya yang sangat murah (US$20 per bulan untuk kecepatan uplink minimal 1 Mbps dan dowload yang tak terbatas).

Permasalahan pokok kedua bangsa Indonesia adalah masih belum bersihnya pita 2,3 GHz dari ganggguan interferensi akibat dari tidak tertibnya para penyelenggara WiFi yang meningkatkan daya pancarnya lebih dari 100 mWatt demi memperluas jangkauan. Akibatnya, muncul spurious frequency diluar pita WiFi 2,4GHz yang melebar ke pita 2,3 GHz yang sangat mengganggu efektivitas transmisi WiMAX. Hal yang sama juga akan dialami oleh LTE, bila nantinya dialokasikan di 2,3GHz.

Persoalan pokok ketiga bangsa Indonesia, adalah sempitnya kapasitas Backhaul antara BTS dan BSC atau Simpul Jaringan, karena masih menggunakan transmisi radio E1 atau kelipatannya, dan baru sedikit yang menggunakan Serat Optik. Jaringan Backbone Serat Optik di wilayah Indonesia Barat saat ini sudah mencukupi (Papala Ring?). Sehingga untuk wilayah Barat, yang masih dibutuhkan adalah Jaringan Backhaul untuk menghubungkan BTS-BTS, bukan Jaringan Backbone (Palapa Ring?). Jadi jangan mengaitkan kebutuhan Jaringan Backhaul dengan Jaringan Backbone Palapa Ring, sebab ini adalah dua hal yang berbeda.

Kenyataan lain saat ini, belum pernah ada studi komprehensif di Indonesia yang menyimpulkan bahwa layanan 4G belum dibutuhkan di Indonesia. Kenyataannya, kebutuhan akan transmisi data berkecepatan tinggi saat ini sudah sangat dibutuhkan oleh bangsa Indonesia, terutama dengan populernya uploading di Youtube untuk membuat seseorang menjadi "Instant Artist" seperti halnya Briptu Norman Kamaru.

Bukti lain bahwa saat ini bangsa Indonesia sudah sangat membutuhkan layanan 4G berkecepatan tinggi adalah dengan membuka link URL http://copensat.com dan menikmati "Opera van Pesat" yang dimainkan oleh para senior ex-Indosat.

Peningkatan kebutuhan layanan data dipicu oleh penetrasi berbagai jenis perangkat mobile dengan beberapa pengembangan terhadap sistem operasi baru yang menggunakan interkoneksi internet. Meningkatnya kebutuhan akan layanan data ini sudah tidak lagi dapat ditampung oleh sarana telekomunikasi data dengan teknologi seluler generasi ke-3 atau 3G.

Menurut Director & Country Manager Qualcom Indonesia Harry K Nugraha, LTE merupakan solusi perkembangan layanan data baik untuk CDMA maupun GSM sebagai evolusi teknologi seluler Generasi ke-3 (3G) ke generasi ke-4 (4G).

Menurut Kepala Pusat Informasi dan Humas Kementrian Kominfo Gatot S. Dewabroto kebijakan mengenai implementasi LTE belum diputuskan, meskipun sudah ada beberapa operator telekomunikasi yang sudah melakukan ujicoba. Sampai sekarang masih dibahas dan kajiannya belum diputuskan. Kementerian Kominfo tidak akan membatasi ujicoba LTE oleh operator, selama tidak digunakan untuk layanan komersiil.

Berita tersebut diatas dikutip dari Harian Bisnis Indonesia terbitan Jumat, 8 April 2011. Yang menjadi pertanyaan adalah bagaimanakah kelanjutan dari penggelaran jaringan Wireless Broadband Access WiMAX sudah ditetapkan pada pita frekwensi 2,3 GHz, sebab belum terdengar layanan jasa komunikasi broadband wireless access untuk masyarakat umum, dimana sasaran semula BWA yang diharapkan dapat menjadi andalan kebangkitan Industri Manufaktur Nasional menjadi tidak terlaksana, karena standar yang ditetapkan menghasilkan produk yang tidak kompetitif di pasar dalam negeri.

Pengalaman keterlambatan/kegagalan penggelaran jaringan BWA perlu menjadi pelajaran yang berharga untuk merancang masa depan jaringan BWA/LTE. Apakah BWA/WiMAX akan tetap dilanjutkan ataukah akan diganti dengan BWA/LTE? Dapatkah LTE menjadi andalan kebangkitan Industri Manufaktur Nasional seperti yang diharapkan dari WiMAX?

Perbedaan utama antara keduanya, adalah, WiMAX merupakan produk bukan propritary, sedangkan LTE adalah produk proprietary, sehinggan Indonesia harus membayar lisensi/paten produk ini. Ini akan mengurangi manfaat pengembangan Industri Manufaktur DN yang berbasi LTE.

Silahka diberikan tanggapan atau saran-saran yang positif.
