Technology Review: Mobile Carriers See Gold in Femtocells - 0 views

  • Mobile Carriers See Gold in Femtocells If consumers buy in to private wireless phone networks, the industry could save money.
  • Strong cell signals at home are certainly a plus, but it's not clear how much consumers will pay for this, analysts say.

      If I brought AP, why should I pay for the Wireless Access Provider? If I have paid for the access, why should I investigate on infrastracture myself, but not by wireless operator? I won't buy femtocell unless operator pay me!!!
  • Sprint, one of the first companies to start commercial trials of the products, is offering them to consumers in Denver and Indianapolis for $50 apiece, along with an offer of lower-priced calling plans--altogether a substantial subsidy.

      That is a fair play.

  • an acceptable price range for consumers used to buying products such as Wi-Fi modems

      It is not true! Since WiFi is much faster than 3GPP, 3GPP AP should be cheaper...
  • may be built into other devices, such as Internet routers for consumers.

      And customer should be benefit from subsidy by operator.

Sanity check: The 700 MHz auction will tip the wireless balance, but in which direction... - 0 views

  • Sanity check: The 700 MHz auction will tip the wireless balance, but in which direction?
  • these two are also likely to delay the move to open platforms.
  • AT&T and Verizon would ultimately slow the growth and adoption of the mobile Internet if either of them won 700 MHz Class C.

  • If Google does win and start a new wireless broadband network, it would put tremendous pressure on the leading wireless carriers to open their networks and play fair.

Secrets of 700-MHz Spectrum Auction - Bob Cringely - Google - FCC - Sprint - WiMAX - Po... - 0 views

  • Everything You Always Wanted to Know About the 700-MHz Auction but Were Afraid to Ask: Expert Op-Ed
  • America’s mobile phone oligopoly
  • 700-MHz signals propagate better, spreading farther and penetrating buildings more easily than higher frequencies

  • having lower so-called spectral efficiency
  • require smaller cells and lower power to reduce interference and increase the total data throughput not per cell but per square mile
  • Which makes one wonder: Why is a data-centric company like Google even interested?
  • simply bidding to make sure some of its open access requirements are imposed on an eventual winner, which will only happen under FCC rules if the bidding for that C Block goes to at least $4.6 billion
  • trade that block to Sprint/Nextel for some of that company’s 2.5-GHz WiMAX licenses
  • The thought of unused or underused spectrum got the juices flowing at companies including Intel, Microsoft and Philips, who banded together to propose that they be allowed to offer unlicensed data service in so-called “white space” within and between existing broadcast frequencies—piggybacking, as it were, on the bandwidth allocated to TV broadcasters and wireless providers.

      trend??? by Ericsson Polarized antenna setups for SDMA by polarization. Thus only long term CQI is needed and less inter-stream interference. For DFT beamforming unitary precoding is better than non-unitary precoding when using less-bit quantilized codebook.
