It is built on LTE (Long Term Evolution, the 4G radio standard) and standardised by 3GPP, using the evolved Multimedia Broadcast Multicast Service (eMBMS) and its further-enhanced variant Further evolved Multimedia Broadcast Multicast Service (FeMBMS), also called LTE-based 5G Broadcast. This project provides the reference transmitter and receiver so anyone can test a complete broadcast chain, covering end-to-end 5G Broadcast systems for TV and radio distribution over dedicated broadcast carriers, without a return channel or SIM requirement on the receiver side. The project also covers hybrid broadcast/broadband delivery and integration with DVB-I service discovery. For the deployment configurations and full feature-support detail, see Implementation status; to see one assembled scenario already running, see the Tutorials.
