Competing Technologies
Main competing technologies of MBMS include DVB-H/DVB-T, DVB-SH, DMB, ESM-DAB, and MediaFLO. However, due to spectrum scarcity and the cost of building new broadcast infrastructure some of these technologies may not be viable. MediaFLO has been deployed commercially in the US by Verizon Wireless through their relationship with MediaFLO USA, Inc. (a subsidiary of Qualcomm) however the service was shut down in early 2011. DMB and DVB-H trials have been ongoing for more than a year now, like those during the football 2006 championships in Germany.
Huawei's proprietary CMB is a precursor to the Multimedia Broadcast Multicast Service. It was specified in 3GPP R6 and is using existing UMTS infrastructure. Huawei says that CMB is based on existing UMTS infrastructure and real time streaming application protocol and requires only a software upgrade to existing UMTS infrastructure. Huawei says it will maintain CMB and help to smoothly migrate to MBMS, but that by deploying CMB ahead of MBMS, operators will gain the advantage of two years of experience in streaming service deployment.
