Google is Building High Frequency Wireless Test Network at Its Headquarters

Experiment could portend a broader rollout of high-frequency networks to reduce congestion
Google Inc.'s (
) headquarters may be the testbed for a new kind of high frequency, dense wireless network that will require kinds of devices not typically sold on the U.S. market today. The producer of the world's top smartphone platform in unit sales last week filed
U.S. Federal Communications Commission
to make use of the 2524-2625 band.
Currently, U.S. high-speed networks,
such as LTE
, use either the 700-800 MHz band or the 1700-1900 MHz band. Meanwhile Europe, Asia, and South America have all looked to the 2500-2600 MHz band for high-speed data traffic.
The growing use of this higher frequency band means that Google won't necessarily need to bake up brand new devices for its mobile network, which, according to the document, will initially consist of 5 to 10 base stations serving up to 40 user devices.
Currently, the 2500-2600 MHz region is set aside by the FCC in most areas for use by the
Educational Broadband Service
(EBS). Clearwire Corp. (
) currently owns most of the reuse rights to this band.

This is by no means Google's first experimental deployment of a wireless network, though it's the first major effort in the cellular space. Google previously offered up free Wi-Fi to his headquarters hometown of Mountain View, Calif. More recently, it jumped onboard a plan to provide free Wi-Fi
to New York City's Chelsea neighborhood
. Google has also offered
free Wi-Fi seasonally
at some airports. Google has also trialed a high-speed fiber-based broadband internet and telephone service
in Kansas City
to be in talks with Dish Network Corp. (
) or other cable internet/television providers to offer broader deployments of fiber optic broadband and wireless services. Thus far, though, all of Google's efforts remain in the experimental stage, with no announced plans for a broad commercial rollout.

What are you smoking..15MW? 15MWs (J) is enough energy to melt 15kg of steel, so the base stations would have to be huge to handle that and then standing at a distance of ~50m from the antenna would be equivalent to being inside a micro wave oven.
a quick search gave this:
" A typical value for macro cell base station is 20-69 W at the antenna connector."

Haha, yeah 15MW is ridiculous! That would be like 5 full sized American locomotives at full speed.
