IN MY OPINION
Small is Bigger, Better and More Innovative?Small is Bigger, Better and More Innovative?

By Bob Pinato,
ICCS, LLC.


Here we are four years into the worldwide economic crisis, which to date has yielded one of the worst financial downturns the western world has seen since the 1930s, and still there is debate whether or not we are facing a long anticipated election year upturn. Military budgets are being scrutinized carefully for the proper balance between the costs for national security, secure jobs in key congressional districts, pet pork programs and the cost of the war efforts.

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...
