Concise Overview
- ACMA introduces new mobile coverage criteria categorizing areas with signal strengths under -115dBm as ineffective.
- Telstra may need to revise its coverage maps, affecting an area of one million square kilometres.
- TPG and Optus endorse the new criteria, promoting enhanced accuracy in coverage representation.
- Telstra claims its tests indicate usability at lower signal strengths, prompting questions about real-world relevance.
- Providers must refresh their coverage maps every quarter to represent service updates.
ACMA’s Updated Mobile Coverage Criteria Ignite Industry Discussion

New Coverage Mapping Standard Implemented
The Australian Communications and Media Authority (ACMA) has established a new mobile coverage mapping standard. Coverage regions will now be categorized based on four levels of signal strength: excellent, fair, usable, and no coverage. Any area with signal strength beneath -115dBm will be classified as unusable.
Impact on Telstra
In accordance with these updated guidelines, Telstra might have to reevaluate and possibly retract its existing coverage representations, influencing around one million square kilometres classified as serviced zones.
Responses from the Industry
Telstra’s rivals, TPG Telecom and Optus, have supported the revised standards, asserting that they will deliver a more precise depiction of actual mobile service accessibility. Both firms argue that the new benchmark more accurately represents the dependability of mobile networks.
Telstra’s Position
Telstra has rebutted the new regulations by displaying its network data, which suggests substantial usage within the newly defined signal levels. The telecommunications company claims that even at reduced signal strengths, critical functions such as emergency calls remain viable.
ACMA and Consumer Confidence
ACMA Chair Nerida O’Loughlin highlighted that the updated standards will allow consumers to make informed choices by comparing similar coverage from various providers, fostering trust in service declarations.
Revising Coverage Maps
All telecom providers are required to update their coverage maps quarterly to stay current with any changes in network infrastructure, ensuring clarity and precision for users.
Conclusion
The ACMA’s revised mobile coverage mapping standards have initiated a notable discussion within the telecom sector. With the new -115dBm benchmark for usable service, Telstra faces the challenge of modifying its coverage assertions, while TPG and Optus view this shift as a significant step toward increased transparency for consumers. The dialogue underscores the difficulty of reconciling technical specifications with genuine mobile user experiences.
