China Mobile network transmits live, high-quality video of Xiamen marathon for broadcasters
For the first time in the world, TD-LTE (time division duplex long term evolution) technology has successfully been used for a live TV broadcast. On January 5, China Mobile’s TD-LTE network transmitted a live video stream of the Xiamen International Marathon to TV centers of China Central TV and Xiamen TV for live broadcasting. The TD-LTE network, solely built by Nokia Siemens Networks, exceeded required parameters to transmit high-definition (HD) video and images from cameras on the move, providing the best live TV experience, matching a relay via satellite. This technological feat ushers in a new era for future outside TV broadcasting using LTE.
As sole supplier of the Xiamen network, Nokia Siemens Networks’ high-quality TD-LTE network supported the entire event with a zero bit error rate. In spite of the increased demand for network capacity with exceptional traffic and load conditions, there was no degradation in network performance, no packet loss and no delay during the two and a half hour live transmission of the mega event on the move. A stable uplink throughput of 5 Mbps (megabit per second) ensured perfect video quality for the smooth TV viewing of millions of viewers worldwide.
“This world-first is yet another proof point for us as a leader in driving the TD-LTE innovation, globalization and commercialization,” said Markus Borchert, president of Nokia Siemens Networks Greater China Region. “With our advanced TD-LTE technology, we ensured optimal network performance with ultra high-quality and reliability for China Mobile to support such a mega international event with very high data traffic.”
For the TD-LTE network, Nokia Siemens Networks deployed its Single RAN Advanced platform, based on its high-capacity Flexi Multiradio 10 Base Station, to China Mobile’s TD-LTE pre-commercial trial network in Xiamen. The company also provided its Liquid Core-based Evolved Packet Core (EPC) platform, including Flexi NS (Network Server) and Flexi NG (Network Gateway). In addition, the company provided its NetAct network management system, enabling consolidated monitoring, management and operation of China Mobile’s networks.
