Leaky cables bring mobile communications to subway systems.
 In its relatively short lifetime, the mobile phone has developed from an interesting novelty to an essential tool. We’re on the phone everywhere and any interruption in our ability to communicate is regarded as a major inconvenience.
Witness the desperate attempts of passengers to maintain conversations as they descend into the London Underground and the quizzical stares at mobiles as their trains enter the tunnels which give the network its name.
The London Underground network is one of the world’s largest urban transportation systems. It has 249 miles of track, of which 45% are underground. Providing mobile phone coverage to those tunnels has been on the table for years. To date, that solution has yet to be determined.
But other cities around the world have managed to do just that. In places such as Hong Kong, Singapore, Beijing and Glasgow, passengers can enjoy – if that’s the right word – the benefit of mobile phone communications wherever they are in the city; and that includes when they’re on underground trains.
Markus Kalt is vice president of business development, EMEA, for Andrew’s wireless innovation group. He described the importance of this in Hong Kong. “The ability to use a mobile phone has a very special place in Hong Kong. Because apartments there are often very small, people tend to ‘live in the streets’. Mobility is very high and the mobile phone has very high penetration.”
