IN MY OPINION
Two Sides of the DoD Coin: Budgets Slashed, UAV Market Soars

By Fred Ortiz, President
dB Control


As we embark on a new year, imminent cuts to the U.S. Department of Defense (DoD) budget are top of mind for those of us in the military electronics market. At a recent House Armed Services Committee hearing, the nation’s military chiefs cited a $600 billion defense cut as “catastrophic to the military” and having a “severe and irreversible impact.”

LightSquared:
The Show’s Over
…Or Should Be
By Barry Manz

There are a lot of very technically astute people at the Federal Communications Commission. Many have decades of experience at every level of RF and microwave technology. How then might LightSquared’s proposal for a satellite/terrestrial LTE network have ever gotten past its first hurdle? Even a cursory inspection of the plan, in which the company's network would operate extremely close to GPS frequencies at L-band, makes interference to GPS devices almost a certainty. Read More...
