They aren't even sufficiently close to that yet. Let alone start from scratch with 5G. The original switch-off date for Airwave was supposed to be the end of 2019. Many don't expect that to happen for a least five years, and that's sticking with 4G. -- Roland Perry |

Plod was still using motorola analogue trunking systems only 15 years ago - I used to listen to them on a scanner. Tetra is a lot newer than DAB! |

They aren't even sufficiently close to that yet. Let alone start from scratch with 5G. 5G is all hype. Yes it allows fantastic download speeds - as long as you're within site of a transmitter. Go behind a wall or around a corner and the speed soon drops off as the frequency simply doesn't penetrate matter very well. Blanket coverage of 5G simply won't happen as it'll require far too many base stations and associated equipment and wired links and would cost an absolute fortune which the phone companies don't have. Its just marketing hype to part the usual techno-suckers from their money in order to get smartphone sales back up. |

Well yes, but surely if it's layered on top of 4G it could also be layered on top of 5G and any subsequent radio data bearer of a similar ilk? I wasn't suggesting it could only be on 4G but made forward compatible so it wasn't getting to be obsolete by the time rollout was completed. |

The money to put the 4G on the tube is coming from the much-delayed Emergency Network project. There isn't any money to install 5G, and it's far too late to start changing the Emergency Network spec to include 5G. That's the kind of thing which makes large government IT projects even later and more over budget than they already are. -- Roland Perry |

That's the kind of thing which makes large government IT projects even later and more over budget than they already are. And even more out of date. Combined base stations and aerial arrays are already available and they should have been using those even if they aren't turning on the 5G bit now. This is particularly true as 5G is far better at dealing with high densities of users which a tube station / train is a rather good example of. |
