This seems to be a new spectrum tune that makes no sense to me:
<"It really doesn't make any sense ... to use [LMDS spectrum] for video," Hardin said, because the "cell structures are too small." In other words, the spectrum isn't expansive enough to deliver a video signal. Instead, the top bidders likely will use their spectrum for "telephony or data, as a base business. Video needs a fair amount of bandwidth," he said - more than the 150 MHz to 1150 MHz in the LMDS spectrum. > More than 1150MHz??!! DirecTV has 500MHz x 2 polarizations, and they use the same QPSK modulation that seems the modulation of choice for optimum utilization of 28GHz (Nortel/BNI is the only exception I am aware of, with a QAM design.) I think there are 4, maybe 5 cable systems in the country with more than 750MHz. You have to wonder what he is thinking if 1150MHz isn't enough for a full service network capability with video, data, and voice capacity. That does not mean that it is prudent or economic to bundle those services on an LMDS platform, or even that it makes economic sense to deliver consumer multichannel video. But to explain video away as too much of a spectrum hog for LMDS, well, please. |
