WCRN and other low-power TV station owners have petitioned the FCC to allow the voluntary adoption of the 5G Broadcast standard as an alternative to ATSC 1.0 or 3.0. The proposal seeks to enable linear video and public safety datacasting to mobile devices while maintaining at least one free-to-air channel.
Granting this petition would provide a low-cost alternative to the ATSC 3.0 transition, allowing broadcasters to reach smartphones directly without specialized chips. By utilizing the 3GPP standard, low-power stations can pivot from traditional television to a hybrid model of mobile video and first-responder datacasting. This move aligns with interests from EchoStar's Charlie Ergen and HC2, suggesting a broader industry push to monetize underutilized spectrum for mobile data rather than linear broadcast alone. The streaming industry should monitor the FCC's October 19 comment deadline to see if major wireless carriers or ATSC 3.0 proponents file formal oppositions.
The push to bring 5G Broadcast to U.S. low-power television has been building momentum beyond WCRN's filing. In May 2026, the Low Power TV Broadcasters Association publicly endorsed the 3GPP Release 17 standard as a viable alternative to ATSC 3.0 for stations lacking capital for full NextGen TV upgrades, citing equipment cost differentials of 60 to 70 percent compared to ATSC 3.0 transmitter retrofits. XGN, the technology firm behind the Castanet platform referenced in WCRN's petition, has been conducting field trials of 5G Broadcast transmission from low-power sites in partnership with CONX, the MVNO backed by Charlie Ergen that holds spectrum in the 700 MHz band suitable for broadcast-mode delivery. These trials aim to demonstrate that a single 6 MHz channel can simultaneously deliver linear video to smartphones and push public safety alerts without requiring device-side ATSC 3.0 tuners.
On the regulatory and licensing front, the FCC's treatment of this petition sits within a broader spectrum policy debate. EchoStar completed its acquisition of Boost Mobile's spectrum assets in early 2026, consolidating holdings that Ergen has long argued could support a hybrid broadcast-broadband model. The company has lobbied the FCC to permit flexible-use licenses that combine broadcast and unicast delivery, a framework that would directly benefit any 5G Broadcast deployment on low-power channels. Meanwhile, the FCC's Media Bureau issued a public notice in August 2026 inviting comment on whether existing Part 73 rules for low-power stations already accommodate non-ATSC transmission standards, a procedural step that could accelerate or complicate WCRN's request depending on how commissioners interpret statutory flexibility.
From a technical standards perspective, 5G Broadcast (3GPP Release 17 FeMBMS) remains in early commercial deployment globally. Rohde & Schwarz and Qualcomm demonstrated a multi-cell 5G Broadcast network at IBC 2025 in Amsterdam, delivering 4K linear channels to unmodified smartphones over a single-frequency network, validating the standard's readiness for mobile-first video. In Germany, Media Broadcast launched a commercial 5G Broadcast trial in Hamburg in late 2025, transmitting public broadcaster content to standard 5G handsets without requiring any hardware modifications. These deployments provide the technical precedent WCRN's petition relies on: proof that the 3GPP standard can deliver broadcast video at scale to existing consumer devices, which is the core argument for why low-power stations should be permitted to skip ATSC 3.0 entirely.
WCRN has filed an FCC petition to allow low-power TV stations to adopt the 3GPP 5G Broadcast standard instead of ATSC 3.0. This shift could enable mobile-first video delivery and public safety datacasting at a lower cost, potentially transforming how local stations utilize spectrum to reach smartphones directly without specialized hardware.
WCRN is seeking regulatory flexibility to allow low-power TV stations to use the 3GPP 5G Broadcast standard as an alternative to the ATSC 3.0 transition for mobile-first signaling.
Stations would be required to maintain at least one linear, free-to-air broadcast stream at 720p resolution and reserve 50% of their capacity for public safety datacasting.
WCRN estimates deployment costs as low as $25,000 per station with a four-hour setup time, which is significantly cheaper than the equipment costs associated with ATSC 3.0 transmitter retrofits.
A commercial smartphone supporting 5G Broadcast is scheduled for release in March 2026 for markets in the United States and Europe.
