This paper presents a link utilization performance analysis of the hybrid WiMAX-Wi-Fi and WiMAX video surveillance systems. Link utilization is ratio of throughput to capacity expressed as a percentage. Therefore, Link utilization measurement must take into account throughput, packet losses and signal-to-noise ratio. A WiMAX-Wi-Fi video surveillance system consists of a Base Station (BS) which is connected in a point-to-point configuration with the Customer Premises Equipment (CPE). The base station then connects to the Internet, routers and video servers. The CPE has a Wi-Fi and WiMAX wireless interfaces. Results show that the hybrid WiMAX-Wi-Fi video surveillance system outperforms the WiMAX in throughput, packet loss and signal-to-noise ratio terms. The hybrid WiMAX-Wi-Fi is 4.5 times better in utilizing the WiMAX link than the WiMAX system.
