Mobile Network Resilience: 72-Hour Backup Could Cost €11bn a Year

Alternatives to blanket coverage

The researchers do not treat the blanket approach as the only option. They point to alternatives, which suggests that a targeted strategy could reach key resilience goals at lower cost than equipping every site with a multi-day buffer. Details of these alternatives were not available in the material at hand.

Why it matters

Mobile networks carry emergency calls, warnings and everyday communication. When towers lose power and their batteries run down, coverage fails just when people need it most. The debate therefore concerns who pays for greater resilience, and how much protection is proportionate.

For network operators, regulators and politicians the estimate provides a benchmark for the discussion. An annual cost in the billions would ultimately be reflected in investment budgets or consumer prices, which is why a differentiated approach is likely to be considered.
