WiMAX/BWA

Atoll WiMAX is a state-of-the-art WiMAX and Broadband Wireless Access (BWA) network planning
tool developed in cooperation with WiMAX equipment manufacturers. Atoll WiMAX supports the IEEE 802.16d and the evolving IEEE 802.16e standards.
It also supports advanced antenna diversity systems, such as Adaptive Antenna Systems (AAS) and Multiple-Input-Multiple-Output (MIMO).
