"What happens when every wireless user has an iPhone, a Palm Pre, or a BlackBerry Tour?" Speaking at CTIA Wireless IT & Entertainment in San Diego today, FCC head Julius Genachowski has said that he wants to "close the spectrum gap" -- the difference between the spectrum it's making available for wireless data versus enormous usage projections (400 petabytes a month by 2013, he says) that'll be brought about by smarter, easier-to-use devices and ubiquitous high-speed data through a handful of initiatives including the promotion of the smart use of existing spectrum through the use of femotcells, WiFi, and smart antennas, and -- more importantly -- reallocation of existing spectrum. Genachowski says there are "no easy pickings" for reallocation, but the Commission is aggressively pursuing additional airspace that can help keep 4G rollouts on track. He's gone on to say that they'll be adopting the widely-discussed "shot clock" policy for placement of new towers, giving locales a limited window to protest placement of cell sites that'll help spread 4G services over wider footprints. The guy seems genuinely concerned about keeping 4G rollouts rolling, so let's see just how far the guys in Washington are willing to go to do that.
