Arraycom and TI team up on MIMO for WiMAX

ArrayComm and Texas Instruments have agreed to combine ArrayComm's smart antenna technology with TI's high-performance digital signal processing for WiMAX and other wireless infrastructure applications.

The combined solution will provide system operators with four-fold improvements in wireless system coverage. Data rates will be more than doubled. Capacity may increase by as much as 10X, all with better coverage quality for 802.16/WiMAX and WCDMA/HSDPA networks.

The combination of ArrayComm's Network MIMO smart antenna software and TI's family of high-performance TMS320TCI6482 DSPs on a single reference design provides base station equipment manufacturers with critical differentiation including shorter time to market, higher equipment performance and greater flexibility as wireless standards evolve.

The first step is a reference design for WiMAX infrastructure applications that incorporates ArrayComm's Network MIMO software. It will support multiple input / multiple output (MIMO), adaptive antenna system (AAS) and combined MIMO/AAS modes.

ArrayComm's Network MIMO software implements all the antenna processing aspects of the WiMAX profiles approved by the WiMAX Forum Mobile Task Group (MTG) for IEEE 802.16e. MIMO and AAS, used in combination, increase subscriber data rates, improve cell-edge link budgets, manage interference, and maximize overall network capacity.

For the first time, ArrayComm' Network MIMO software has been ported to TI's 1 GHz TMS320TCI6482 DSP. This optimized DSP performs at nearly twice the clock speed of other available solutions, yet consumes only three watts of power, making it the industry's most power efficient DSP for wireless infrastructure systems.
