Executive Summary

Video surveillance is a highly useful tool to the public transport authorities, which is now widely used as a measure to ensure passenger safety and security. While video surveillance application in static environments like airports, shopping malls, train stations has been a huge success, real-time video surveillance in moving public transport experiences serious technological challenges mainly due to low data rates at vehicular speeds offered by existing communication technologies. Success of live video surveillance in public transport depends on future communication technologies. WiMAX has emerged as an exciting technology with promises to offer high throughput, a key requirement for video surveillance in public transport. WiMAX, however, offers limited throughput at high vehicular speeds mainly because of multipath fading that causes high bit error rate at the receiver.
