Spatial Division Multiple Access SGSN
Spatial Division Multiple Access. A complement (not an alternative) to CDMA and TDMA, this technology increases the number of users that can access an existing wireless phone or data system by exploiting the spatial characteristics of the channel itself through highly developed implementation of an intelligent antenna system’s capabilities for receiving and transmitting.
SDMA is a multiple access technique based upon sharing the access to the network on a geographical basis whereby the service area is divided into non-overlapping cells containing low-power transmitters.
