Bandwidth Prediction on a WiMAX Network

The IEEE 802.16 standard (WiMAX) is an important next-generation networking technology which promises high-speed network access for both mobile and fixed users. In this paper we present a method to estimate link quality for devices connected to Temple University´s WiMAX network as they traverse both the main campus and the city of Philadelphia via foot and motor vehicle. This is accomplished by first measuring receive signal strength indicator (RSSI), carrier to interference plus noise ratio (CINR), and bandwidth. After capturing these values, we then analyze the data to provide an estimation of the actual system rate. We then present an approach to predict future states of link quality both while stationary at Temple and when traversing Philadelphia via bus.
