Atoll Microwave is a state-of-the-art point-to-point and point-to-multipoint backhaul planning and optimisation software. It allows designing and planning large microwave link networks as required for 5G deployments, according to ITU recommendations, industry standards, and operator guidelines.


Atoll Microwave powerful link planning tool

Atoll Microwave is based on the leading Atoll software platform which includes a high-performance GIS and advanced data and user management features. It provides mobile operators with a comprehensive framework for the design and planning of point to point and/or point-to-multipoint microwave links and transmission backhaul.

Full integration of Atoll Microwave with Atoll radio planning modules allows immediate sharing of radio planning and optimisation data for backhaul planning. Atoll microwave also takes advantage of the Atoll platform GIS, user and data management, and reporting features.

Atoll Microwave is being used by a number of major wireless operators and equipment vendors worldwide.

Atoll Microwave also includes a Backhaul Capacity Planning module that allows mobile network operators (MNOs) to model backhaul network topologies and to dimension backhaul links according to the mobile network traffic. The Backhaul Capacity Planning module enables the analysis of end-to-end mobile traffic routing and the optimisation of backhaul capacity. Atoll Microwave also supports non-line-of-sight backhaul enabling small cell planning and 5G network design activities.
