Sprint makes official offer to acquire Clearwire in General Topics Posted December 21, 2012 In conjunction with my post above, here are some scientific developments that obviate the need for additional spectrum: The method -- time-domain transmit beamforming -- involves digitally creating a time-domain cancellation signal, coupling it to the radio frequency front end to allow the radio to hear much weaker incoming signals while transmitting strong outgoing signals at the same frequency and same time. Today's wireless radios use two separate channels to transmit and receive signals, but full duplex radios transmit signals at the same time in the same frequency band. This can double the efficiency of the spectrum, but the problem is often interference between the transmission and receiving functions on full duplex radios. http://www.innovationgeneration.com/author.asp?section_id=2807&doc_id=256003& And algebraic answers to the capacity crunch: http://www.innovationgeneration.com/author.asp?section_id=2557&doc_id=253598 That woman is an idiot and doesn't understand what she's talking about. TCP isn't licensed from anyone and the technique deals with TCP throttling due to missing packets, where reconstructing the missing packet greatly increases throughput by avoiding both the latency (where all subsequent packets are useless until the retransmit succeeds) and the receive window scaling where TCP tried to adjust to the bandwidth. Basically TCP assumes low packet loss which is often not the case for WiFi links. Not to mention TCP is not the only protocol used on the Internet.
