Qualcomm pushes for 300Gbps in-flight broadband

Mobile chip and network gear maker Qualcomm has now proposed an in-flight wireless network that would bring speeds as fast as 300Gbps. It would use spectrum in the 14GHz to 14.5GHz bands for this, and the so-called Next-Gen AG system would use about 150 towers located throughout the US. The network would use familiar airwave techniques to get ther, including a time division duplex communications mode and orthogonal multiplexing, which stitches together multiple signals into a coherent whole.

Qualcomm's EVDO tech is used on the ground for the Gogo in-flight Wi-Fi system. The chipmaker said that it uses just 3MHz of spectrum and could thus soon reach its limits as more and more passengers put a strain on it. Gogo is planning on addressing this by bringing in directional antennas, dual-modems and EVDO Rev. B tech to the 100 or so ground towers.

The Next-Gen AG system has backing from American Airlines, Virgin America, and Delta Airlines. Gogo supports it as well, but stipulates that the FCC should not grant both 250MHz licenses to one company. Opposing the idea is Row 44, a Gogo rival used on Southwest Airlines, along with Boeing, the Satellite Industry Association, Panasonic Avionics Corporation, and others. They believe the new system would cause interference to adjacent bands currently in use.

Qualcomm may bid to buy the spectrum itself, of simply profit by selling hardware to whoever does buy the spectrum. [via FierceBroadbandWireless]
