Atoll enables designing, planning, and optimising Wi-Fi networks based on the IEEE 802.11 WLAN standards. It provides comprehensive Wi-Fi network modelling with coverage and capacity planning as well as multi-technology traffic modelling and analysis (e.g. HSPA/LTE/Wi-Fi).

Atoll's multi-technology multi-layer RRM features enable operators to plan and evaluate Wi-Fi based scenarios for network capacity enhancement.


Atoll's Wi-Fi features are part of the Atoll WiMAX/BWA module, which delivers a comprehensive set of features for the design and optimisation of WiMAX, Wi-Fi, and other Broadband Wireless Access (BWA) technologies.
