Freescale, TTP partner on white space broadband basestation


TTP and Freescale  are collaborating to develop low-cost terminals and base stations to support “last-mile” delivery of broadband service to consumers and small businesses using the new M2M white space spectrum.

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.

According to Richard Walker, Head of Wireless for TTP, the 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.

Similar in size to current-generation home routers, the systems being developed are engineered to deliver broadband over white space at speeds comparable to cellular LTE. By combining several TV channels and using directional antennas, said Walker, data rates can be maximized.

“Enabling communities with affordable, robust broadband service in locations where wired infrastructure is impractical or uneconomical is one of the great challenges for the telecommunications industry over the coming years,” he said. “White space broadband is significantly faster and lower cost to deploy than optical fiber over long distances in remote areas.

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 system they are developing also includes Freescale’s gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) amplifiers.

“As IP traffic continues to grow exponentially around the world, spectrum has become an increasingly rare and valuable commodity,” said Tareq Bustami, vice president of product management for Freescale’s Digital Networking business.

The QorIQ Qonverge BSC9131 base station-on-chip is based on 45-nm advanced process technology. It includes multi-standard acceleration technology that adds flexibility and reduces costs for OEMs.

An onboard Multi-Accelerator Platform Engine for baseband, called MAPLE-B, works in concert with the high-performance and fully programmable DSP core to support Layer 1 processing for 3G-LTE, TD-SCDMA, WiMAX and WCDMA standards.

A high-performance Power Architecture e500 MPU coupled with a smart Ethernet controller and a security encryption accelerator balance the device to handle Layer 2/3, transport and control functions.
