LightSquared: Will Persistence Pay Off? By Paul Kruczkowski, editor
Since it began its bid to become a major player in the broadband wireless 4G-LTE market back in 2010, LightSquared has faced a multitude of technical, regulatory and political setbacks. The biggest blow came earlier this year, when the Federal Communications Commission (FCC) rescinded its conditional waiver for terrestrial service, saying that LightSquared had failed to adequately resolve GPS interference issues. LightSquared subsequently reorganized under chapter 11 bankruptcy. Down but not out, the embattled company is continuing its quest to deploy a 4G-LTE network, now proposing to share government spectrum and regain use of part of its licensed spectrum below the GPS band.
Theory And Application Of RF And Microwave Absorbers By Emerson & Cuming Microwave Products
Absorbers in the RF/microwave realm are materials that attenuate the energy in an electromagnetic wave. Absorbers are used in a wide range of applications to eliminate stray or unwanted radiation that could interfere with a system’s operation. Absorbers can be used externally to reduce the reflection from or transmission to particular objects and can also be used internally to reduce oscillations caused by cavity resonance. They can also be used to recreate a free space environment by eliminating reflections in an anechoic chamber.
The Warrior Cable with internally armored GrooveTubeCable technology is a field-proven design that provides repeatable and dependable performance in extreme conditions for electronic countermeasures, SATCOM, and EW systems.
MCLI's 16-Way Power Dividers and Combiners feature excellent phase noise and amplitude balance, high isolation and reliability, low insertion loss, low VSWR, and stripline construction. They're ideal for applications involving signal measurement, feedback monitoring, combining/splitting antenna signal feeds, and antenna beam forming.
