3GPP Release 19 freeze finalizes 5G-Advanced standards for wide-area streaming

The finalization of these specifications provides the protocol stability necessary for vendors like Ericsson to begin field deployments in 2026. For the streaming ecosystem, the shift to native NR-MBS allows operators to offload high-bandwidth live events from congested unicast channels to efficient broadcast streams. This architectural maturity also serves as a critical bridge to 6G, particularly through standardized AI-driven resource management and integrated non-terrestrial networks. Watch for the first Release 19 information elements to appear in live network signaling traces later this year as operators begin testing these 5G-Advanced features.

Ericsson has been among the most vocal proponents of 5G Broadcast as a commercial use case for NR-MBS. In early 2026, Ericsson and Qualcomm demonstrated NR-MBS multicast delivery over a live 5G network at Mobile World Congress, showing simultaneous delivery of a 4K live stream to multiple devices on a single carrier frequency. The demonstration used a 100 MHz channel in the 3.5 GHz band and achieved per-user throughput comparable to unicast while consuming a fraction of the radio resources. That proof of concept directly validates the Release 19 NR-MBS specifications that 3GPP finalized this week.

On the regulatory and business side, the European Broadcasting Union has been pushing for 5G Broadcast integration into national spectrum frameworks. In March 2026, the EBU published a position paper urging EU member states to reserve portions of the 700 MHz band for NR-MBS services, arguing that without dedicated spectrum allocation, operators will prioritize unicast revenue over broadcast efficiency. Germany's Federal Network Agency has already signaled openness to the proposal, and Deutsche Telekom confirmed in June 2026 that it plans to trial NR-MBS for public broadcasting in the 700 MHz band by year-end. These moves suggest that Release 19's freeze provides the technical foundation, but commercial rollout still depends on spectrum policy decisions at the national level.

From a technical standpoint, RedCap (Reduced Capability) devices represent another key Release 19 feature with streaming implications. Qualcomm announced in May 2026 that its Snapdragon X75 modem platform supports both RedCap and NR-MBS reception, enabling lower-cost IoT and wearable devices to receive broadcast content without full 5G NR complexity. Independent testing by RootMetrics found that RedCap devices consumed 40% less power than full NR modems during continuous video streaming sessions, a finding that could accelerate adoption in connected-vehicle and smart-venue scenarios where battery life matters. The convergence of NR-MBS broadcast efficiency and RedCap device economics positions Release 19 as the specification set that makes 5G datacasting rules commercially viable for mass-market streaming use cases.
