In June 2017, the international standardization committee 3GPP (3G Partnership Project) completed the "Release 14" development stage. This supports important requirements for broadcasting services in large-cell 4G and 5G networks. With these developments, Release 14 approaches the parameters that have been common in classical terrestrial broadcasting transmission methods so far.
The improvements include reception without SIM card and without authentication, as well as the option to make up to 100 percent of the transmission capacity available for broadcasting applications in the new FeMBMS mode - the further development of the LTE broadcast mode eMBMS. Significantly increased transmitter inter-sites allows the use of broadcast transmitter sites for economical area coverage. In addition, FeMBMS enables larger transmitter cells in a single-frequency network. A pure receive-only mode, without the necessity of a return channel, was also established in the 3GPP standard, as was the definition of audiovisual transport and coding formats currently used in broadcasting.
IRT is actively involved in 3GPP standardization and regulatory issues in the relevant groups (5G Media Initiative, 5G Exchange Platform of BNetzA, ITU WP-5D and EBU-FD (Future Distribution), as well as corresponding subgroups), in particular in the ongoing Work Item Descriptions (WIDs) to further improve Terrestrial Broadcast for Release 16 and AV production.
