  • 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.

  • 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.

      Samsung's Pattern is the worst. Since they put the pilots too close, the t-f position far from pilots has too week correlation with pilots and so is worse performance. Pilot should be placed uniformly.
