Google builds its own wireless network
Google wants permission to build an experimental wireless 2.5GHz network to test secret technology using 50 base stations and 200 devices.
The network will squeeze into two 2MHz-wide slots, starting at 2524MHz and 2567MHz, and will use both directional and omni-directional antennas mounted on walls and ceilings across the Google campus over the next two years - but what kit or protocol it will be using remains a mystery.
The bands fall within the "3G Expansion" band, generally referred to as 2.6GHz, which are being auctioned off around the world for 4G (LTE) deployments. LTE can be squeezed into 2GHz, but the band being used by Google is paired with one much higher up the spectrum that's almost certainly a red herring.
What's more likely is that the band was a convenient one for testing, and the testing is most likely to be in White Space database techniques which we know Google is actively involved in developing.
Google is one of the companies planning to run a White Space database in the US, but most of the companies involved are planning to add some intelligence to the process in the cause of differentiation.
