Qualcomm is turning off 5G NR-NTN by default on its newest chipset because there are no commercial low-Earth orbit (LEO) satellites available to test the feature. That choice highlights how direct-to-device (D2D) 5G from space still runs into the same bottleneck: satellites, device support, and economics haven0t all arrived together.
SpaceX is building a 5G-like path using 3GPP Release 19, and Qualcomm is betting on NR-NTN0s efficiency versus direct-to-cellular (DTC). But the near-term reality is that X105 will ship with NR-NTN disabled, leaving field trials for later.
Why NR-NTN is disabled on Qualcomm0s newest chipset
Qualcomm decided to disable 5G NR-NTN by default because it cannot test the capability in a commercial LEO satellite internet network yet. The company0s X105 Modem-RF is Qualcomm0s first product to support 3GPP Release 19 for 5G NR-NTN, but Qualcomm plans to ship it to customers with NR-NTN disabled for the same reason.
Qualcomm expects X105 to be integrated into smartphones hitting the market in the fourth quarter of this year, and into devices for larger volume customers in the first quarter of 2027. Customers could enable NR-NTN in their labs or over the air once satellites become available.
Francesco Grilli, Qualcomm VP of product management, linked the software/hardware readiness problem to in-orbit verification: If you have satellites today and we can test and verify that everything works, then you can have a commercial launch as soon as the customer unboxes the device. But without first testing with at least a few satellites in orbit, that cannot happen.
SpaceX and other operators set schedules, but availability drives timelines
SpaceX confirmed earlier this year that its next-generation non-terrestrial network (NTN) constellation will be built on 3GPP Release 19 to deliver 5G-like data from space to smartphones. The company targets starting launching its larger V2 satellites in mid-2027 for the Starlink Mobile NR-NTN-based service and expects support on most devices in the US by the time that service starts, promising up to 150 Mbit/s on the downlink.
Elsewhere, Amazon Leo plans to deploy a new D2D system in 2028, pending its acquisition of Globalstar. AST SpaceMobile says its satellite technology is built on 3GPP NTN standards, but it has launched only one next-gen craft out of a planned 45 by the end of the year.
NR-NTN vs DTC: Qualcomm0s capacity-and-spectrum-efficiency case
Qualcomm0s internal argument is that NR-NTN0s efficiency can outweigh DTC0s faster time-to-market. The core trade is that D2D satellites adapt signals by changing the frequency and timing so devices do not know the signals are coming from a satellite; the same article says that losing some signal properties degrades services by a factor of four to ten.
Grilli framed the degradation as a huge loss and said that, for the same amount of spectrum, satellite complexity, and power on the satellite, 5G NR-NTN is four to ten times more efficient in spectrum use than any direct-to-cellular (DTC) system that can be conceived. He also said the only advantage of DTC is that it can be deployed today with legacy devices for faster go-to-market, but it takes a big hit on capacity.
Standards adoption is building, but the device and business case remain hurdles
FDM CCS Insight principal analyst Luke Pearce said NR-NTN requires new infrastructure, new devices, and new economics, and he made the remarks at the Mobile Network Innovation Summit last week. Pearce also said the anticipated timeframe for NR-NTN services is towards the end of the decade and at least two to three years away.
Pearce argued that standards-based NR-NTN is gaining acceptance as the better option for D2D services in the long term, and said that standards work for 6G will see even more integration between satellite and cellular networks. But the first challenge is device support: NR-NTN can extend connectivity beyond smartphones to cars and IoT devices, while Pearce said it will still be a very long time until there is a mass user base because consumers do not replace handsets as often as they used to.
He also pointed to physical constraints, including the size of the antenna required, and said there are big questions about the business casewhether there is enough money in the market for all the innovation and for new LEO constellations that will have to support NR-NTN. Pearce said people are still figuring this out and noted potential opportunities in automotive and other industry verticals beyond keeping consumers connected off the terrestrial grid.
