The battle for white space frequency spectrum between Microsoft and Google has finally come to an end. White spaces has moved into a new era with FCC’s decision this November, to allow consumer electronic companies access to these broadcast frequencies. This move saw a new chapter being created in media history.
The frequency bands upto 806 MHz range where over to air channels 2-139(VHF) and 14-69(UHF) operated for over 50 years is called white spaces. These white spaces were much in demand with both Microsoft and Google wanting a share of it. The 700 MHz range is the band that is most sought after by media wireless companies because it allows for optimal frequency propagation, with unhindered RF travel.
Lengthy tests carried out by FCC helped determine how new and existing applications could use the space without hindering each other. Months of testing included use of NFL games as test beds. The outcome of the tests were in the negative and in spite of this, FCC Chairman Kevin Martin has thrown open white spaces to all new and existing media players.
With white spaces thrown open to new media companies, wireless broadband connectivity is poised for improvement.
White Spaces have been thrown open with certain stipulations, which have to be followed. Spectrum sensing is to be incorporated by all new devices as it allows airwaves to be scanned and detected. Another stipulation is the establishment of RF database to notify which channels are currently in use around the country. White spaces devices cannot connect to other devices without Internet access or use of GPS.
