Deal To Be Signed For Mobile Coverage On Tube

Via Ian Visits and London Reconnections: A website called Cellular-News is reporting that a deal to bring mobile phone coverage to the Tube could be signed very shortly.

Back in September, we reported that discussions between the various interested parties were underway, with Boris Johnson "bashing together" the noggins of network CEOs in order to get things moving. Under the £150 million contract, which could be signed in weeks, services from the four main mobile networks would be trialled on the Jubilee and Central lines in time for the 2012 Games ("the most digital Olympics ever!"), with other lines being connected afterwards. The deployment on those two lines make some sort of sense, as the Central and Jubilee are the two Tube lines that run to Stratford, and will probably bear the brunt of Olympic traffic.

For those interested in the technical aspect of Tube telephony, London Reconnections says that the system will use "leaky feeders" (no snickering at the back please), a common method for underground communications networks, including the New York and Moscow subways (and indeed used by existing Underground station radios). A relatively low-tech solution, and one that might not provide the most complete or trouble-free service, but probably the easiest to get up and running.

There's nothing particularly low-tech about leaky feeders! They're perfect for use in tunnels - there's a fat copper cable running along the tunnel, and as you've got coverage as you're near the cable. And the nature of tunnels means that you're near the cable. Antennas are only useful where you're covering a large open area, so in the tunnels you'd get loads of blind spots and a lot more equipment.

Enough about the tube, tell us about the Leaky Feeders...

Couldn't they think of anything better to spend £150 miwwion pound on?

In most transport networks, the networks (or sub contracted agents) install the mobile coverage infrastructure themselves at their own cost - and often then pay a rental fee to the railway network.

If that model is followed in the UK, then far from costing the Underground any money, it will actually raise money for them.

Low tech? Not true! Ok lets be clear the term is not “Leaky Feeder” but “Radiating Cable”.
The only other alternative is to use antenna’s which is not possible in the LUL due the space between the tunnel and the train. Also “radiating Cable” provides the most uniform coverage in tunnels whilst being relatively broadband for future applications.

I will miss the silences, and the lovely moment where the shouty idiot stops saying "hello? yeah, i'm on the train...can you hear me?" as the train pulls into the tunnel.

I don't care... I'm using the Overground to get to work! :-).
