Adaptive Wireless™

Adaptive Wireless™ is a unique, software defined feature set which runs with Icera’s Livanto® soft baseband, to allow device manufacturers to develop multiple products with difference performance levels, all from a common platform. This has big advantages for device manufacturers: reduced cost of ownership, faster time to market, higher performance and a roadmap to support multiple future standards.

Today Adaptive Wireless™ delivers the world’s highest performance multimode 4G LTE / 3G / 2G solution.

Adaptive Wireless™ Advantage

With conventional hard-wired solutions it is necessary to instantiate all signal processing algorithms used to receive and decode the signal as separate areas of silicon. This approach results in a high-cost solution with inherent inflexibility. Verification of these separate hardware operating modes is arduous and problematic. This leads to a solution that cannot possibly provide optimum performance under all circumstances as inevitable compromises are made with algorithm parameters.

In contrast, by implementing these complex algorithms in software, Icera is not constrained to always use the same receiver architecture. A menu of receiver algorithms, including rake, advanced receivers and receive diversity, for example, can be made available to the modem, without incurring increased cost or increased silicon verification time. The Adaptive Wireless™ solution, at any given instant in time, selects the optimum mixture of algorithms that will maximize system performance. This judgment is based upon a large number of criteria and optimization constraints. Channel conditions are continuously monitored, together with other performance metrics, to determine the best receiver configuration to deliver the highest possible performance.

This dynamic receiver architecture delivers dramatic performance throughput gains and receiver sensitivity advantages. Files download in under half the time of other solutions. Web browsing is noticeably faster. Network carriers achieve this dramatic user experience advantage with more than a doubling in sector capacity and a consequent halving in per-megabyte delivery cost.
