The proliferation of technology in the home creates a wide range of choices for the consumer. Serving this audience requires deciding on what types of technology to integrate into control devices - the main access point for home entertainment and appliance control.
Radio Frequency (RF) has emerged as a leading option that offers many benefits. A methodical approach is required in selecting ...
A Wireless Internet Service Provider (WISP) currently has an LMS8000 900MHz NLOS system deployed throughout a town and surrounding area. The current system is used to provide broadband Internet access mainly to a residential subscriber base with a slight mix of small businesses. Of this subscriber base, 30% of the installs are indoors within 1.5 miles of the CAP sites and the rest are outdoor ...
It is a simple fact of physics that lower frequency radio energy travels farther through cables, through the air, and through and around clutter like trees, hills and buildings. This note provides examples of propagation loss to be expected in the 900 MHz band, the 2.4 GHz band, and the 5.8 GHz band.
A fundamental tenet of the Spectrum Bridge business plan is that the US Government, under the auspices of the FCC, will permit spectrum owners to sublicense their spectrum and facilitate an open market for spectrum brokering.

This white paper describes the design of the Symmetricom Model 8130A Rubidium Frequency Standard (RFS), modern ruggedized RFS intended for military applications and other harsh environments.
We describe an optically-pumped cesium beam frequency standard under development for deployment on the GPS-III satellite constellation. In particular, we discuss the design choices that have been made with particular emphasis on optical pumping and interrogation techniques, laser and optical technologies, and the realization of the prototype frequency standard. Preliminary performance data is ...
A single frequency network (SFN) enables highly efficient distribution of digital content over a wide area. Easier, faster and less expensive to service a geographic area from a grid of transmitters than using a web of copper or fiber, SFNs address the need to bring high-quality video and audio services to mobile users – with a network that can serve all users. This white paper discusses ...
This white paper focuses on the Xli Time and Frequency System. Continuously locked to GPS, the disciplined 5071A Cesium Oscillator Option is an ultra precise time and frequency reference that offers the ultimate in stability against environmental effects.
This application note discusses how the massive 2003 power outage that left over 50 million people in the dark did indeed shed light on one critical issue facing power companies — the role of synchronized timekeeping.
YellowFin™ Mobile WiMAX analyzer is the world’s first truly portable calibrated, demodulating WiMAX test receiver. This handheld unit utilizes the Samsung ...
