Has New Jersey 5G

Mobile TV reloaded

Multicast has been planned since 3G

Standardized mobile radio technologies for multicast transmissions have been around since 2006, when the subsystem MBMS (Multimedia Broadcast / Multicast Service) was specified in 3GPP Release 6 (UMTS). With Release 9, it was further developed into eMBMS (evolved MBMS) and incorporated into LTE, in order to finally reach the development stage FeMBMS (Further evolved MBMS) in Release 14 (LTE Advanced Pro). This was adopted by 3GPP under the name "LTE-based 5G terrestrial broadcast" largely unchanged in Release 16 and is therefore now also an official part of 5G.

The technologies for terrestrial broadcasting and mobile communications have been converging for a long time. Both now rely on signal feed via IP networks and OFDM at the air interface. The transmitter receives its user and configuration data via 3GPP-compliant protocols. The signal processing of a DVB-T2 transmitter can be adapted to the FeMBMS specifications with a manageable effort. The frequencies are compatible anyway if the broadcast takes place in the original TV bands that were added to mobile communications as a digital dividend in broadcast digitization or as a result of spectrum repacking.

Compatible end devices must support receive-only mode without a SIM card (free-to-air) so that the service can also address devices that are not registered in a cellular network, such as television receivers.
