Have they got the emergency services' Tetra radios working in the Tube
yet? This was one of the recommendations post 7/7. Presumably it'd
be relatively easy to piggy-back civilian mobile traffic onto that
infrastructure if it has actually been completed.

If the emergency services had adopted GSM Pro instead of Tetra,
they could have added leaky feeder down the tube for all to use
at least 10 years ago.

ISTR we had this argument somewhile ago and did we came to any
conclusion why it wasn't done?..

I mean sound engineering reasons?..

Tetra has nothing to do with sound engineering reasons, it's entirely
political and a means of funnelling large quantities of taxpayers
money to O2 Airwave.

Some fairly bald assertions, there. And wrong, too.

Firstly, perhaps you can point us at a capabilities specification for
GSM Pro and take us through how it meets the requirements that Tetra
meets to match the ERC specification.

Secondly, the TfL Tetra rollout doesn't involved Airwave, other than
requiring interworking.
