Base station-on-chip enables innovative white space broadband
White space is license-exempt radio spectrum that exists between licensed TV transmissions. Globally, more than 100 MHz of prime UHF white space radio spectrum exists in many rural locations and is characterized by excellent propagation characteristics ideal for long-range communication. Enabled by the right multicore SoC and RF solutions, the spectrum can be used to deliver data at high speeds across a distance of many miles. White space spectrum is ideal for providing fixed broadband internet services to locations where the routing of cables or optical fiber is neither practical nor economic.
TTP and Freescale are collaborating to develop low-cost terminals and base stations engineered to support “last-mile” delivery of broadband service to consumers and small businesses. Similar in size to current-generation home routers, the TTP solution is engineered to deliver broadband over white space at speeds comparable to cellular LTE. By combining several TV channels and using directional antennas, data rates can be maximized.
Freescale’s QorIQ Qonverge BSC9131 processor will handle the entire wireless stack from Layer 1 to transport and other processing duties for the TTP white space solution. The TTP solution additionally includes Freescale’s MMZ09312B, MMZ25332B, MML09211H and MML20211H advanced gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) amplifiers featuring exceptional linearity and power efficiency.
TTP is an established leader in white space development and was one of the first to demonstrate the potential of using TV spectrum for the delivery of broadband by linking its head offices in Hertfordshire, UK, to a rural village in Cambridgeshire in 2012.
