Representatives of Google and Microsoft urged the FCC to adopt technical rules permitting the use of three 801.11af channels in the 600 MHz band following the TV incentive auction, in a series of meetings with commission officials. The companies elaborated on their arguments in an ex parte filing in docket 12-268. The companies urged that the rules allow the operation of Mode 1 and 2 personal/portable unlicensed devices in the duplex gap, the lower guard band and Channel 37, the filing said (http://bit.ly/1uEzbyS). They argued that a database should be allowed to determine unlicensed device operation based on the device’s location-accuracy capabilities so devices with better accuracy can operate in appropriate locations, rather than preserving the current rule, which mandates that all devices establish location within +/- 50 meters. Unlicensed systems should be allowed to determine areas where devices can operate in the broadcast band using both the database and sensing, Google and Microsoft said.
