Unwired Australia Pty Ltd was an Australian company dedicated to fixed wireless telecommunications network offering carrier grade Internet services. They provided coverage in Melbourne and Sydney. Unwired had 52,320 customers and 97 employees. The technology used by Unwired was provided by American manufacturer Navini Networks〔(【引用サイトリンク】url=http://www.pba.com.au/index.php?page_id=154 )〕 and Venturi Wireless Solutions. Unwired utilised a wireless network similar to WiMax, using base towers that broadcast a microwave signal, offering speeds of up to 1024kbit/s. The Unwired network was the first data only network providing Internet services in Australia. Unwired customers used external modems to connect to the wireless network. Unwired technology was portable, but not mobile - the technology does not operate well while the receiver was in motion. The network operated at 3.5 GHz within a spectrum exclusively reserved for use by Unwired. Unwired offered free technical support 7 days a week plus public holidays. Optus bought out Unwired and shut down the Unwired network at midnight on 28 February 2013. ==Corporate acquisitions== The Seven Network Limited's subsidiary Network Holdings acquired Unwired in 2008〔(Seven Network Limited Annual Report 2008 )〕 for a reported $127 million. Seven Network Limited owns 50% of the Seven Media Group which owns the Seven Network. At this time Unwired CEO David Spence left the company. Unwired was later consolidated into Seven's wireless broadband division, Vividwireless which was based in Perth. Australia’s second largest telecommunications company, Optus, announced in February 2012 that it would buy Vividwireless from its parent Seven Group, for a total cost of $230 million. Optus said this would create a new 4G mobile broadband network in Australia. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Unwired」の詳細全文を読む スポンサード リンク
