Brief Overview
- Telstra alerts that LEO satellite constellations are unprepared for 000 calls.
- LEO satellites require a “critical mass” for dependable emergency communication.
- The UOMO commitments might need to be postponed until at least late 2028.
- Telstra has noted a rise in outages tied to LEOsat backhaul.
- The absence of LEOsat caused major community effects on the availability of emergency calls.
Telstra’s Apprehensions Regarding LEO Satellite Abilities
Telstra has expressed apprehensions about the preparedness of low earth orbit (LEO) satellite constellations to facilitate trustworthy 000 emergency calls. The telecommunications leader has notified the federal government that these systems must attain a “critical mass” to ensure sufficient support for emergency services.

The Importance of Achieving a Critical Mass
Telstra’s alert corresponds with its earlier guidance that 5G non-terrestrial network standards are still under development. The merger of terrestrial and non-terrestrial networks is crucial for delivering reliable SMS, voice, and data services. Until LEOsat densities reach necessary levels, consistent emergency communication will continue to be difficult.
Postponements in UOMO Commitments
The telecommunications provider recommends pushing back the Universal Outdoor Mobile Obligation (UOMO) until a complete ecosystem, which includes adequate LEO satellites and infrastructure, is established. Telstra foresees that this may not be realized until late 2028.
Effects of LEOsat Services on Emergency Communication
Telstra’s dealings with Eutelsat’s OneWeb LEOsat constellation reveal the obstacles encountered. Transitioning from geostationary to LEOsat backhaul resulted in a 43% rise in mobile tower outages. These outages brought considerable disruptions to the availability of 000 calls, with certain base stations unable to manage emergency calls for up to 35 minutes each day.
Conclusion
Telstra’s cautious outlook on the preparedness of LEO satellites for emergency services highlights the necessity for a well-rounded infrastructure before depending on them for crucial communication. As Australia advances its telecommunications capabilities, ensuring sturdy and dependable emergency call systems remains a principal concern.
