Quick Read
- TPG Telecom and Optus are contesting Telstra’s assertions regarding mobile coverage mapping with ACMA.
- The discussion centers on the signal strength benchmarks for assessing usable coverage.
- Telstra advocates for a lower benchmark of -122dBm, while competitors back ACMA’s -115dBm standard.
- ACMA’s revised standard seeks to enhance consumer awareness of mobile coverage.
- Potential legal and regulatory consequences could arise from the updated mapping criteria.
- The industry is encouraged to achieve an agreement before the standard is enacted.
Coverage Mapping Debate Intensifies
TPG Telecom and Optus are disputing Telstra’s claims regarding the usability of mobile services in regions with less robust signal strengths. This controversy is escalating as the Australian Communications and Media Authority (ACMA) introduces new mapping standards for mobile coverage.

Signal Thresholds at the Center
ACMA’s draft suggests that regions with signal strengths lower than -115dBm should not be categorized as having usable service. Telstra, however, advocates for a lower benchmark of -122dBm, a position that TPG Telecom and Optus oppose.
Telstra’s Marketing Claims Under Examination
TPG Telecom accuses Telstra of overstating its coverage, asserting it encompasses areas where mobile services may be unreliable. Both Optus and TPG support ACMA’s proposed threshold, arguing that it better reflects the accurate portrayal of usable coverage.
ACMA Clarifies Its Justification
ACMA’s -115dBm threshold is grounded in international standards and the National Audit of Mobile Coverage (NAMC) initiative. This standard is designed to produce clearer coverage maps with designations for good, moderate, usable, and no coverage.
Possible Customer Misunderstanding
Telstra contends that ACMA’s methodology could mislead consumers, influencing their choices regarding service plans and usage. The carrier points out that a significant number of its customers depend on coverage that falls below the -115dBm threshold.
Optus Backs -115dBm Benchmark
Optus maintains that the -115dBm benchmark is the minimal level at which consumers can anticipate a dependable mobile experience. It opposes any lower threshold, believing it could misrepresent the reliability of coverage.
Telstra’s UOMO Concerns
Telstra expresses apprehensions that the new standard might conflict with upcoming Universal Outdoor Mobile Obligation (UOMO) legislation, which mandates providing coverage over wide areas and may rely on satellite systems.
Industry Encouraged to Find Common Ground
TPG Telecom and Optus are advocating for additional industry discussions ahead of finalizing the new standard, expected to be completed by the month’s end. ACMA aims to enforce the standard by June 30.
Summary
The discussion surrounding mobile coverage mapping in Australia sees TPG Telecom and Optus disputing Telstra’s proposal for a diminished signal strength threshold. With ACMA’s new standard on the horizon, industry participants are urged to achieve consensus for clarity and precision in representation of coverage.
