TV white spaces (TVWS) are unused TV broadcast channels, made available through the transition from analog to digital TV. With today’s spectrum scarcity crunch, the availability of approximately 200MHz of additional spectrum is monumental especially for under-served markets.
TVWS are located in the VHF and UHF bands and have several important benefits that make them highly desirable for wireless communications including.
• Ability to cover a greater area at a relative lower cost
• Non-line-of-sight performance offers the ability to penetrate obstacles such as trees, buildings, and rugged terrain
