Title: Prediction of Wireless Network Signal Strength Within a Building

Abstract: With the increase in the provision of access to Wireless Local Area Networks and the abundance of user devices capable of utilising Wi-Fi, the design of the network infrastructure has introduced some significant problems. Prior to the installation of Access Points it is difficult to predict whether access can be guaranteed at specific locations. Additionally, to increase the level of security, it is often preferable, despite the use of security protocols, to ensure that the signal strength is not large enough to enable connection in areas other than those designated. By combining the theory of antennae and the measurement of the performance of devices, it is possible to predict whether access is likely and hence how secure the network design is. Additionally, the use of a simple application is proposed that enables the network designer to enter a configuration and produce an answer showing if WIFI will operate and a value to indicate the margin.
