As mobile data usage skyrockets, wireless companies are spending billions each year to maximize capacity, and consumers end up footing the cost in the form of higher cell phone bills. But a cube that fits in the palm of your hand could help solve that problem.

It's called lightRadio, a Rubik's cube-sized device made by Alcatel-Lucent that takes all of the components of a cell phone tower and compresses them down into a 2.3-inch block. Unlike today's cell towers and antennas, which are large, inefficient and expensive to maintain, lightRadio is tiny, capacious and power-sipping. As tiny as it is, it has been tasked with solving an enormous problem. When conceiving of lightRadio, Alcatel-Lucent's engineers stripped out all the heavy power equipment that controls modern cell towers, and moved them to centralized stations. That allows the lightRadio cubes to be made small enough to be deployed virtually anywhere and practically inconspicuously: Atop bus station awnings, on the side of buildings or on lamp posts. Their small size and centralized operation lets wireless companies control the cubes virtually. That makes the antennas up to 30% more efficient than current cell towers. Live data about who is using the cubes can be assessed, and the antennas' directional beams can be shifted to maximize their potential.
