Texas Instruments, Sub10 Systems Collaborate on Backhaul Solution

Texas Instruments (TI) and Sub10 Systems, a manufacturer of point-to-point millimeter-wave radio links, is collaborating on a differentiated and future-proof backhaul solution for small-cell base stations. By incorporating TI’s KeyStone-based TMS320C6678 multicore digital signal processors (DSPs) in its new Liberator V100, Sub10 Systems will be able to more effectively and rapidly meet operators’ challenges of improving resilience in hostile radio conditions.

“TI’s KeyStone-based products are a perfect complement to our design philosophy,” said Stuart Broome, CEO, Sub10 Systems, in a press release. He continued to say that a device is needed that’s powerful, scalable and flexible to support an expanding range of radio products, which can minimize development time and cost. “TI’s multicore DSP gives us exactly what we want, including more processing power and onboard accelerators with higher performance and plenty of a design margin, allowing us to continuously innovate to improve the performance of our product,” said Broome.

Sub10 Systems’ Liberator V100 is designed for use by mobile operators looking to increase network coverage and capacity. It plays a vital role in the backhaul of mobile networks, connecting mobile voice and data traffic from the cell site to the high-speed core network.

TI’s DSPs offer Sub10 Systems access to devices that have high performance while being power and space efficient. The strengths of the DSPs help Sub10 Systems include developing backhaul solutions small enough to fit on lamp posts, and maintain power management.

Backhaul Solution for Urban Small-cell Networks

The Avenue Link Lite sub-6-GHz point-to-point microwave radio from DragonWave has a form factor of only 7.5 inches square, including an integrated antenna. The unit supports licensed and unlicensed spectrum and is suited for non-line-of-sight (NLOS) deployment scenarios where obstructions are found between link endpoints. The unit offers full scalability and is designed within specifications that ensure compliance with strict city-zoning regulations in order to blend into the urban landscape. It can be configured and monitored remotely. Streamlined functionality is complemented by low power consumption (less than 15 W), PoE compatibility, reduced cabling requirements and in-band synchronization, which eliminates the need for an external synchronization source. The high-capacity and low-latency capabilities make it one of the first LTE-ready NLOS systems. It can be deployed using a tree topology, with macrocell traffic aggregation points on rooftops, or with tail, chain or small hub microsites at street level, which reduces interference and offers more flexible network connectivity, as well as simplifying network expansion and helping to ensure protected network architectures. www.dragonwaveinc.com
