AirHop Communications and NetLogic Microsystems are working together to develop reference designs for small-cell heterogeneous 3G and 4G/LTE mobile networks.

Powered by NetLogic's multicore, multithreaded processors, these reference designs will highlight the capabilities of AirHop's Evolved Self-Organizing Network (eSON) technology to manage interference and optimize spectrum reuse in multi-layer wireless network environments. The first reference design demonstrates eSON technology running on NetLogic's XLR processor in a multi-base station configuration within a simulated RF environment.

"Mobile broadband traffic is exploding. Unfortunately the available spectrum to support it is finite," indicated Peter Jarich, service director with Current Analysis. "LTE or the expansion of macrocell footprints alone won't solve this problem. Instead, operators will need to look to new network architectures and embrace small cells in order to ensure quality of user experience. With the adoption of small-cell architectures, however, comes the need for innovative technology to address interference and spectrum reuse issues associated with heterogeneous deployments. These issues can degrade capacity as well as quality of service and perhaps more onerously, have the potential to generate excessive customer support calls."

The reference design combines AirHop's eSON software with Trillium LTE software from Continuous Computing, both running on NetLogic's XLR532 processor with 32 virtual CPUs. This scalable solution can be adapted to address a wide range of eSON-enabled equipment, from base stations requiring dedicated processors to server-based applications where multiple base stations could be controlled from a single multi-threaded processor.

"This collaboration with AirHop demonstrates our commitment to deliver best-in-class solutions for our mobile infrastructure OEM customers who are developing next-generation LTE equipment," said Dilip Ramachandran, senior director of marketing, multicore processor products at NetLogic. "These eSON reference designs will enable our OEM customers to more rapidly evaluate, develop and deploy next-generation RAN equipment with advanced interference and spectrum management capabilities. We are excited to be the silicon vendor powering AirHop Communications' innovative eSON technology, and are proud to add them to our expanding ecosystem of solution partners."

"AirHop has been developing solutions for operators to address interference and spectrum reuse in the small-cell environment since 2007," added Garrett Choi, chief operating officer at AirHop. "Our eSON technology enables the wide-scale deployment of small cell base stations in heterogeneous environments, including macrocell base stations sharing the same spectrum, and NetLogic Microsystems' multicore, multi-threaded processors are a perfect fit for our software. NetLogic Microsystems is well-positioned to serve our target customers, and we look forward to benefiting from their strong processor roadmap."
