SDMA

 

Space Division Multiple Access (SDMA)



SDMA Technology

SDMA enables simultaneous downlink communications with multiple users over the same frequency channel, thus increasing significantly the network capacity.

Wavion's unique SDMA technology creates two downlinks to two different users simultaneously, transmitting one data stream per user. Each stream is "beamed" by means of Beamforming in such a way that the user receives only the stream directed to him, while the other steams are received below the noise level. This doubles the network’s downlink capacity.


Increased Capacity and Coverage with Beamforming and SDMA, over conventional Wi-FI

The improvement in capacity and range resulting from SDMA and spatially adaptive Beamforming are presented in the diagram. Wavion's SDMA performance is compared to a conventional Wi-Fi Base Station in typical Non-Line-of-Sight propagation model. Note that, Wavion’s SDMA technology capacity increase tapers off gradually as the radius from the base station increases. This is a result of the division of power between the two beams.


Wavion’s SDMA capability will be offered as a SW upgrade to all Wavion’s base stations. Network operators are able to upgrade their existing network in order to increase their capacity and improve their networks value.
