More Interference for DoD On the Way?

FCC Chairman Ajit Pai maintains that current limits are fine and enough to ensure public safety, after six years of review with the FDA and other federal health and safety agencies. The exposure limits apply to handheld devices, computers and cell towers, and span technology generations including 3G, 4G, and 5G. Pai’s proposal also seeks to establish a uniform set of guidelines, regardless of the wireless service of technology, for how to determine compliance ...

After hundreds of studies and thousands of peer-reviewed journal articles, the issue remains as poisonous as ever. In fact, the only issue of any kind in any discipline I can think of that has been around for this long is whether vaccinations cause various medical issues, including autism, the flu, and other diseas...

A Word from Sam Benzacar As we’ve noted before in this column, the Department of Defense faces interference challenges at least as daunting as the commercial wireless industry. This situation looks likely to become even more challenging in the future because military radar and satellite communication systems operate at frequencies well into the millimeter-wave region, which is precisely where the fifth generation of cellular is headed. In addition, the FCC’s recent successful spectrum auction has given T-Mobile significant assets at 600 MHz, which is the figure shows covers almost the entire United States. Others gained 600 MHz spectrum as well. This is obviously not the first time the DoD has had to contend with services encroaching on its allocated frequencies. However, even though frequency sharing will be employed at the millimeter-wave frequencies where military satellite communications systems operate, the potential for interference still exists. And allocations below 1 G...
