インターネットイニシアティブ(IIJ)の法人向けデータ通信サービス「IIJモバイル」MVNO(仮想移動体通信事業者)としてNTTドコモから無線設備を借りることで実現した。ユーザーはHSDPAを利用して下り最大3.6Mビット/秒でインターネットに接続できる。NTTドコモが提供するパケット定額プランと異なり,利用できるプロトコルに制限はない。

2007年には,認証や信頼性を高める機能を搭載する製品の裾野が拡大したが,2008年はさらに下位機への搭載が進む。2008年2月に登場する新サーバーOS「Windows Server 2008」の「ネットワークアクセス保護」(NAP)機能と連携させることで,セキュリティ・アプライアンスなどを追加しなくてもLANセキュリティの司令塔が手に入る。既に実装が進んでいる認証機能と組み合わせ,手軽に検疫システムを構築できるようになる。In the U.K, Telefonica O2 this month started testing equipment from NEC Corp. and the ZoneGate femtocell from UbiquiSys Ltd. Unstrung understands that Telefonica O2 will also test a femtocell solution from ZTE Corp.
For the U.K. trials, Telefonica O2 is concentrating on what services can be delivered and how they will be provisioned.
"We're checking out the feature set and seeing if the 'zero touch' is really all that," says Chris Fenton, director of convergence policy at Telefonica O2. "We're really focused on whether we can make the customer experience."
NEC is integrating the Ubiquisys femtocell into its solution, which includes the femtocell gateway and "all the access point management and provisioning system, which makes it all 'zero touch,'" explains Anil Kohli, director for global femtocell competence at NEC Europe.
Telefonica O2 says it plans to expand the U.K. trial in the summer and aims for commercial services in early 2009, if all goes to plan.
If the "zero touch" promise cannot be fulfilled, then that greatly affects an operator's business case. If customers struggle with plugging in, setting up, and getting services on the home base stations, then increased calls to customer support centers will jack up an operator's costs.
Vivek Dev, chief operating officer of Telefónica O2 Europe, said in a statement, “Our Apple iPhone is already driving unheard-of levels of mobile internet usage, and the introduction of flat rate data tariffs is expected to increase this further. Both of these place huge capacity demands on our networks, and because so much of that usage is at home, femtocells coupled with DSL could provide an alternative capacity resource.”
Telefonica O2's trials are limited to the U.K. But Fenton says the trial complements what parent company Telefónica SA is doing in Spain. There, the Spanish operator is testing femtocell kits from Huawei Technologies Co. Ltd. and Alcatel-Lucent.
These vendors will be busy with femtocells in Spain because Vodafone is also testing femtocell equipment from Alcatel-Lucent and Huawei in the country.
Andy MacLeod, global networks director of Vodafone, said in a statement, “Femtocells have the potential to enhance customers’ 3G broadband experience, and the trials are critical to investigate whether the technology can deliver on its promise.”

| The 700 MHz Auction Bids Continue Climbing and Far Exceeding Expectations | |
Even the FCC underestimated the demand for 700 MHz. Originally expected to raise between $10 billion and $15 billion, total current bids exceed $18.9 billion. Bidding on the sought-after C block also surpasses the FCC requirements ($4.6 billion) and now has a PWB (Provisional Winning Bid) of $4.7 billion. ABI Research notes that demand for 700 MHz is so great, not even the pending recession impacts the bidding process. This auction may be the last opportunity for new participants to gain ground in the wireless realm, which is dominated by incumbent carriers. New participants include Google, Vulcan Spectrum LLC, Tower Stream, and Cox, while traditional participants include Verizon and AT&T. “700 MHz provides better propagation characteristics than 850 MHz, 1900 MHz, 2100 MHz, and higher-frequency spectrums,” says ABI Research senior analyst Nadine Manjaro. “For instance, cable companies can utilize this spectrum by launching their own mobile broadband networks – thereby alleviating the need to rely on wireless operators. But Google draws the most speculation, since the company’s entrance into the wireless market could significantly change the wireless industry.” Moreover, incumbent operators absolutely want to strengthen 4G deployments; and 700 MHz will improve rural and in-building coverage at a lower cost than existing frequencies. One surprise is the nationwide D block, set aside by the FCC for public safety. Frontline Wireless – the expected front-runner – was disqualified due to its inability to pay the minimum bid. And there has been only one bid, which failed to meet the reserve bid price of $519 million. The D block price is set at $1.3 billion. “Beginning in 2009,” concludes Manjaro, “the 700 MHz auction could alter wireless broadband services in the United States and abroad. Google’s interest in the C block influenced Verizon’s decision to open up access to its network, just as Apple’s introduction of the iPhone stirred up the cellphone market. If Google or another disruptive player secures the C block spectrum, it could change the whole industry.” ABI Research’s recent report, Global Wireless Spectrum Issues: Market Opportunities and Implications, explores all major spectrum initiatives, highlighting implications for vendors, regulators, and operators. It addresses spectrum trading, mobile liberalization, technology neutrality, and the latest developments in the satellite bands, and covers globally harmonized bands for WiMAX as well.
