Deutsche Telekom multi‑orbit IoT roaming

Deutsche Telekom multi‑orbit IoT roaming
Deutsche Telekom’s launch of seamless IoT roaming across terrestrial, GEO, and LEO networks signals a practical turning point for standards‑based satellite IoT at global scale. Multi‑orbit roaming blends the strengths of geostationary (always‑on footprint, predictable links) with low‑earth orbit (lower latency, better high‑latitude reach) and terrestrial cellular to keep devices online where traditional networks fall short. The service has been validated on Nordic Semiconductor’s nRF9151—billed as the first 3GPP‑compliant cellular IoT module to support terrestrial NB‑IoT/LTE‑M and NB‑NTN over both GEO and LEO—which matters for total cost of ownership and speed to scale.

Iridium & T-Mobile Strengthen 5G with LEO PNT Timing

Iridium & T-Mobile Strengthen 5G with LEO PNT Timing
Iridium and T-Mobile are scaling satellite-delivered positioning, navigation, and timing services under a U.S. Department of Transportation initiative to bolster the resilience of 5G networks against GPS disruptions. The collaboration equips T-Mobile sites with Iridium PNT receivers to deliver precise, authenticated timing that complements existing GNSS sources. Iridium transmits timing over its low-earth-orbit constellation in the L-band, offering weather-resilient coverage and stronger signals than typical GNSS. The service is engineered for sub-100-nanosecond accuracy, uses cryptographic protections for integrity, and can operate indoors without an external antenna, addressing urban canyons, indoor small cells, and hard-to-reach sites where GNSS is unreliable.

AT&T Users Tap T-Mobile Satellite D2D: Ookla Report

AT&T Users Tap T-Mobile Satellite D2D
New usage data shows AT&T subscribers are tapping into T-Mobile’s Starlink-powered T-Satellite more than expected, signaling a rapid shift in how carriers and customers think about direct-to-device connectivity. Speedtest intelligence indicates T-Mobile users account for the majority of direct-to-device (D2D) connections to Starlink, roughly six in ten overall and more than seven in ten among devices reporting active service at connection time. The surprise is AT&T’s footprint: about a third of observed connections come from AT&T subscribers, while Verizon’s share is minimal.

Iridium and Deutsche Telekom begin 3GPP NTN IoT integration

Iridium and Deutsche Telekom begin 3GPP NTN IoT integration
Iridium Communications and Deutsche Telekom (DT) are collaborating to integrate Iridium NTN Direct with DT’s global IoT footprint, enabling DT customers to roam onto Iridium’s low Earth orbit (LEO) network for narrowband IoT. The service targets 3GPP-compliant 5G NTN for NB-IoT, bringing satellite reach to sensors, machines, and vehicles. Commercial launch is slated for 2026, pending integration, testing, and a roaming agreement. DT is among the first major mobile operators to pursue a standards-based NTN IoT integration, aligning with its broad NB-IoT/LTE-M roaming strategy. The pairing aims to offer seamless terrestrial-satellite service without proprietary devices or walled gardens.
