A necessary part of wireless implementation is computer-aided design (CAD) of the Radio Frequency (RF) aspects of point-to-point links and point-to-multipoint networks. This service includes the various phases of RF Planning from Desktop Feasibility to Field Survey and Detailed RF Design.

Link Planning

This CAD allows us to determine the optimum link performance in the case of point-to-point links. The experience of our RF Planners enables us to give a level of confidence that the proposed link will not only work, but will fulfill predetermined performance objectives in terms of link availability under all conditions. The CAD makes use of digital terrain models, weather predictions and system specific data to obtain accurate predictions.

Coverage Analysis

In point-to-multipoint networks using technologies such as WiMAX, the necessity for modeling is even more important. The tools allow us to determine the optimum site for the base stations and to predict network coverage for the Operator. Cell boundary criteria are determined for agreed performance criteria such as Carrier/Interferer level, modulation type or signal level. The CAD tools make use of digital terrain models, clutter models and system specific data to obtain accurate predictions.

The design tools used also allow for analysis of interference caused by adjacent base stations.
