What happened
Ookla analysis of 50M+ signal scans shows London Underground's 5G availability (19.8% of below-ground scans) now exceeds the citywide above-ground average (16.5%), with median 5G signal at -93 dBm underground vs -98 dBm at street level. However, like-for-like comparisons of the same surface areas show street-level signal is still 2-3 dB stronger, meaning the headline advantage comes from the Tube running beneath central London where surface networks are already strong.
Why it matters
Minimal practical impact for this audience. The only transferable insight is that purpose-built underground 5G infrastructure can outperform legacy above-ground networks on a citywide-average basis, which is relevant only if you are evaluating Malaysian transit or tunnel connectivity projects. No action required for developers, AI builders, or founders.
Discussion angle
Brief mention only: contrast London's slow rollout (promised end-2024, now targeting end-2025, only 60% of stations covered) with Malaysia's own tunnel/transit connectivity situation, if anyone in the group has recent experience with KVMRT or ERL signal coverage.
