Twin-Turbo dual transmit uplink technology to provide enhanced performance
Beceem Communications has released a new WiMAX chip BCSx350 which includes ‘Twin-Turbo’ dual transmit uplink technology that provides up to 6dB of performance gain compared to traditional Wave 2 uplink technology.
The company said that the new 4G-WiMAX chip employs MIMO decoder technology and interference-cancellation algorithms that can increase the downlink performance at both high- and lowsignal strength to improve throughput and hand-off performance.
Beceem claims that the newly embedded ‘Twin Turbo’ technology supports peakpower transmit diversity to exploit channel diversity, true uplink beamforming for linkbudget gains in weak signal conditions and uplink spatial multiplexing for throughput increases in rich-scatter environments.
The BCSx350 comes in two models, the BCSM350 for mobile/embedded devices and BCS5350 for high-performance, low-cost CPE (customer premise equipment) that simultaneously support data, voice and WiFi on a single chip.
Lars Johnsson, vice president of marketing and business development for Beceem Communications, said: Performance and market leadership are the hallmarks of our 4G products. We continue to invest heavily in improving the performance of WiMAX networks and devices, and our new BCSx350 chip is by far the most capable 4G-WiMAX chip given its further increased uplink performance and continuously reduced power consumption.
