Crackdown on telco coverage claims | 7.30

Key Concepts

• Decibel milliwatt (dBm): A unit of power level used to measure signal strength in telecommunications.
• RSRP (Reference Signal Received Power): A key metric for measuring the power of the LTE/4G signal.
• Standardized Coverage Maps: A new regulatory requirement forcing telcos to use uniform technical criteria for mapping signal availability.
• ACMA (Australian Communications and Media Authority): The government body enforcing the new standardized mapping rules.
• Thresholds: The specific signal strength levels that define whether a location has "good," "moderate," "basic," or "no" coverage.

1. The Problem: Discrepancy in Coverage Reporting

Robert Smith, a 72-year-old resident of Briagalong, Victoria, has experienced a significant deterioration in mobile service over the last five years. Despite Telstra’s official coverage maps indicating that his home should have reliable 4G coverage (both indoors and outdoors), Smith frequently experiences "no bars," dropped calls, and an inability to access the internet. This lack of reliable connectivity poses a safety risk for Smith, who lives alone and has mobility issues.

2. Regulatory Changes: Standardizing Coverage Maps

For years, telecommunications providers (Telstra, Optus, and Vodafone) set their own internal thresholds for what constituted "reliable" coverage. This led to inconsistent and often misleading maps.

• New Mandate: Following a ministerial direction, the ACMA has ordered all telcos to adopt a standardized set of technical rules for mapping coverage, effective June 30.
• Four-Tier Classification: Maps must now clearly categorize areas into:
  1. Good: High-quality signal for reliable calls.
  2. Moderate: Functional signal.
  3. Basic: Minimal connectivity.
  4. No Coverage: Clearly marked areas where service is unavailable.
• Technical Thresholds: Signal strength will be measured in dBm. Anything above -95 dBm is considered "good," while anything below -115 dBm is effectively unusable.

3. Industry Perspectives and Arguments

• Telstra’s Stance: Telstra opposes the new rules, arguing that they will force the removal of 1 million square kilometers from their coverage maps. They contend that their current threshold of -122 dBm represents "usable" coverage for 1.5 million customers. They argue that removing this from maps could discourage tourism and economic activity in regional areas.
• Regulatory/Expert Stance: The ACMA and industry consultants argue that -122 dBm is functionally useless for modern communication. Experts compare -115 dBm to a whisper in the same room, while -122 dBm is likened to a whisper in the next room—technically present, but practically unintelligible. They emphasize that consumers need accurate data to make informed purchasing decisions.

4. Real-World Application: Testing in Briagalong

A diagnostic test conducted at Robert Smith’s residence revealed an RSRP reading fluctuating between -122 and -125 dBm. Under the new standardized rules, this is classified as "no coverage." This highlights the gap between marketing claims and the actual user experience, particularly when environmental factors like building materials and terrain are not accounted for in store-level sales pitches.

5. Actionable Insights for Consumers

Telco consultant Paul Bedur suggests that consumers living in areas classified as "no coverage" under the new standards should:

• Engage Local Representation: Contact local Members of Parliament (MPs) to advocate for infrastructure improvements.
• Lobby Providers: Directly pressure telcos to install additional towers or strengthen signals in underserved regions.
• Demand Transparency: Use the new standardized maps to hold providers accountable for the services they claim to offer.

Synthesis and Conclusion

The transition to standardized coverage maps represents a significant shift toward consumer protection in the telecommunications sector. By forcing providers to use uniform technical metrics (dBm) and clearly label "no coverage" zones, regulators are aiming to eliminate the "coverage gap" that has historically allowed telcos to overstate their service reach. While providers like Telstra express concern over the economic impact of these changes, the case of Robert Smith underscores the human cost of inaccurate mapping: a reliance on an "essential service" that fails when it is needed most. The takeaway for consumers is to utilize these new, more accurate maps to demand better infrastructure and hold providers accountable for their service promises.
