LTE / 5G Broadcast Evolution


It's been a while since I last wrote about eMBMS. A report by GSA last month identified:
- 41 operators known to have been investing in eMBMS
- 5 operators have now deployed eMBMS or launched some sort of commercial service using eMBMS
- GSA identified 69 chipsets supporting eMBMS, and at least 59 devices that support eMBMS


BBC R&D are testing the use of 4G/5G broadcast technology to deliver live radio services to members of the public as part of 5G RuralFirst - one of 6 projects funded under the UK Government’s 5G Phase 1 testbeds and trials programme (link).

A press release by Samsung Electronics back in May announced that it has signed an expansion contract with KT Corporation (KT) to provide public safety (PS-LTE) network solutions based on 3GPP standard Release 13 for 10 major metropolitan regions in South Korea including Seoul by 2020. One of the features of PS-LTE that the PR listed was LTE Broadcast (eMBMS): A feature which allows real time feeds to hundreds of devices simultaneously. It enables thousands of devices to be connected at once to transfer video, images and voice simultaneously using multicast technology

Dr. Belkacem Mouhouche – Samsung Electronics Chief Standards Engineer  and Technical Manager of 5G projects: 5G-Xcast and 5G-Tours Presented an excellent overview on this topic at IEEE 5G Summit Istanbul, June 2019. His presentation is embedded below.



5G-Xcast is a 5GPPP Phase II project focused on Broadcast and Multicast Communication Enablers For the Fifth Generation of Wireless Systems.

They have a YouTube channel here and this video below is an introduction to project and the problems it looks to address.
