On April 19, the traditional Patriot’s Day in my home state of Massachusetts and the anniversary of the “shot heard round the world” that started the American Revolution, FCC approved the equipment authorization application of Adaptrum, Inc. for a TV white space device for unlicensed use in the UHF-TV band under the rules adopted in Docket 04-186.

Adaptrum ACRS 1.0 White Space Device

The unit was approved as shown above for the frequency range 473.0 - 695.0 MHz, TV channel 14-51, and a transmitter power of 0.617 W. The approval include permission for use of antennas with a gain up to 10.15 dBi, so the device is capable of the maximum 36 dBm, almost 10 dB higher than the only other device that has ever been approved.



Adaptrum also announced a field test of its equipment in rural Nottoway County Virginia. This is an economically challenged area with little broadband connectivity due to disinterest of the mainstream carriers and lack of appropriate technical options in the past. Adaptrum hopes to show how white space technology can improved connectivity in such an area.

Adaptrum, founded in Silicon Valley in 2005, is MSS’ oldest client and we are proud to have played in a key role in assisting them to reach this point.
