Acorn's HellaPHY IP core boosts 4G network performance

4G World 2010, CHICAGO, USA: Acorn Technologies announced the successful integration of Acorn’s chip-level IP core solution for 4G networks—HellaPHY, with LTE and WiMAX platforms from Texas Instruments and Runcom Technologies respectively.

Test results demonstrated a more than 60 percent gain in spectral efficiency for both LTE- and WiMAX-based networks. Acorn Technologies collaborated with AirHop Communications on its HellaPHY solution for LTE.

Acorn achieved standards-compliant integration of HellaPHY into Texas Instruments’ LTE development platform as well as full integration with Runcom’s WiMAX commercial hardware. Significant spectral efficiency gains were observed when HellaPHY was implemented over the baseline approach.

HellaPHY greatly reduces network total cost of ownership (TCO), as service providers can deploy fewer base stations and still deliver a better user experience. HellaPHY works by increasing overall receiver performance, offering capacity improvements under the most challenging mobile channel impairments, including co-channel interference, inter-carrier interference, multi-path interference and thermal noise.

Compared to other technology approaches, HellaPHY provides exceptional spectral gain while retaining critically low implementation complexity.

“In selecting a partner to enhance our OFDM and WiMAX solutions, we look for technologies that deliver on the promise of 4G—higher data speeds and advanced mobile applications,” said Eran Bello, vice president of marketing and sales for Runcom. “As mobile operators continue to deploy WiMAX, service providers are looking for ways to optimize their networks. Acorn Technologies’ HellaPHY integration was very straightforward and the performance is excellent.”

“The combination of HellaPHY with TI’s LTE reference board well exceeded our performance expectations,” opined Hanson On, vice president of engineering at AirHop Communications, Acorn’s LTE Partner. “This platform provides an excellent foundation for LTE basestations that incorporate advanced RAN-management products like AirHop’s eSON.”

Steve Caliguri, vice president of Telcom at Acorn Technologies, stated: “Working closely with industry leading partners like AirHop and Runcom helps to confirm Acorn’s unique signal processing approach that allows for a greatly simplified implementation that provides significant spectral efficiency gains. Independent validation by third-parties obviously adds significant credibility to our product. We look forward to continuing our relationship with our partners in these efforts.”
