[london] How London finally cracked mobile phone coverage on the Underground … IanVisits digs into the engineering and bureaucracy behind getting a mobile signal into the deep Tube. ‘The new network doesn’t just provide phone coverage for customers; it’s also part of the government’s Emergency Services Network and might, in the future, replace staff radios when they’re being upgraded.

Given the hundreds of millions it would cost to upgrade the emergency service network and staff back-of-house radio networks, it makes sense to provide a public service as well.’
