I'm old enough to remember the first attempt at 'mobile underground'. Maybe I've forgotten the name but it was something like BT Phone Zone, though google returns zero relevant results, so perhaps it was called something else. In lieu of public call boxes, BT trialled a base station that was installed in some tube stations (almost certainly Oxford St and Tottenham Court Rd), and with the correct 'wireless handset' as long as you were within 10 feet of it, or thereabouts, you could make a call. I'm sure I remember a semi-circle painted on the ground that if you stood in, you were in range.

You might be thinking of Rabbit: https://en.wikipedia.org/wiki/Rabbit_%28telecommunications%2...

Yeah, I think that's it. Thanks.

Whilst I have seen the Rabbit fittings others have mentioned I do remember mention of a "zone phone" and suspect we're recalling the same thing...

Maybe this?

Was it a Rabbit Telepoint, perchance?

Yes, looks like it. I see it was licensed to a few other companies.
