To validate the LNR performance of delivering live news
content over the deployed WiMAX Infrastructure, two kinds
of performance tests have been done: (1) the availability test
of backbone network; (2) the round-trip time (RTT), packet
loss, and delay jitter of delivering LNR video packets through
backbone network and repeater network over the WiMAX
infrastructure. Since the LNR application includes e-SNG and
WiTV services, the performance evaluations are effective for
both services in our test scenario as shown in Figure
