Report documents interference unlicensed devices would cause TV receivers

The Association for Maximum Service Television (MSTV) last week made public a comprehensive analysis of the interference problems associated with placing unlicensed devices in the TV White Spaces.

According to the MSTV, the report refutes non-interference claims by unlicensed device proponents. The report “responds to the unsubstantiated claims” from proponents of unlicensed devices that such devices won’t cause interference if used in the TV band, said MSTV vice president of policy and technology Bruce Franca.

“The New America Foundation and other proponents simply ignore the complex engineering and technical issues associated with placing these devices in the television band,” said Franca, who is also a former chief of the FCC’s Office of Engineering and Technology.

The report documents “problems with interference from out-of-band emissions, interference from operating on the first adjacent channel and a significant potential for co-channel interference,” said MSTV senior vice president Victor Tawil.
