Project #91: High Performance Indoor Wireless System Deployment

Back

Description:

Indoor wireless communication systems make use of a network of access points placed throughout a building to provide the necessary levels of service.  Limited frequency spectrum resources mean that only a limited number of frequencies/channels are available, and so frequency reuse is inevitably required.  Performance on a given link between an access point and a mobile user is dependent on levels of interference due to interfering transmissions from other co-channel access points (using the same frequencies) located some distance away.  In these situations, optimising system performance requires (i) the careful placement and orientation of access point antennas and/or (ii) installing shielding in order to minimise levels of co-channel interference and thereby maximise performance.

Recently, a software tool has been developed in the Department of Electrical and Computer Engineering which allows the user to model propagation in buildings from which estimates of desired and interfering signal levels can be obtained.  This project will make use of this software tool to investigate a range of typical indoor deployment problems and propose generic rules for optimal system deployment.

Outcome:

Rules for optimal deployment of access points in an indoor wireless communication system.
