Wireless bandwidth: Are we running out of room? [29Jan12] - 0 views

Wireless bandwidth is like land in Manhattan -- it's extremely valuable because they're not making more of it.

But we sure are using more of it. The wireless-industry association CTIA reported in October 2011 that the number of wireless devices in the U.S. had, for the first time, exceeded the number of people. And Mobile Future, a coalition of vendors and consumers, estimated in a March 2011 report that by 2014, voice traffic will comprise only 2% of the total wireless traffic in the United States -- a worrisome statistic because, as the report noted, smartphones consume 24 times more data than old-school cell phones, and tablets consume 120 times more data than smartphones. (See Data needs bandwidth, but how much? for details.)

The result: Wireless networks are edging near capacity, not just in the United States, but all over the world. Credit Suisse conducted a survey last year that revealed mobile networks in North America were running at 80% of capacity, with 36% of base stations facing capacity constraints. The average globally for base station capacity utilization, the report said, was 65%.

The problem is going to get worse before it gets better. With advancements in connected cars, smart grids, machine-to-machine (M2M) communication, and domestic installations such as at-home health monitoring systems, wireless demands will only increase. As with all things mobile, there are no simple answers, if only because potential solutions rely on agreement among a sizable and incompatible array of players -- from spectrum owners (both telcos and broadcasters) and regulators to government agencies and, of course, consumers demanding the latest in cool devices and applications.
