DECT in general (the successor to CT-2 which Rabbit used) is still going strong, though in some bubbles people are shocked to hear anyone uses anything other than a mobile phone.
Is that line of reasoning obvious enough to follow, or do I need to explain further?
The point is: how do you ensure that you always have a phone on you?
It is precisely a long-distance Bluetooth headset in phone form factor. The multi-handset, single-base units are very good.
A lot of modern baby monitors use DECT. Works much better than the old timey one-way radio type too, You'll get alerted if the connection drops, and on a lot of models you even get two-way communication.
And of course I bring an old phone just for the fun of it.
The last 'landline' was going out over the fiber anyway and was some kind of emulation. The router had a phone jack to plug an old school phone in.
AVM also has a line up of smart home devices based on the DECT standard that work in conjunction with their routers.
[1] Just don’t use the phase “at it like rabbits” to mean conversations. Unless you mean Ugandan discussions… [2] VHF was used for the old 405 line system, which was turned off in the ‘80s.
There was a 1981 song in the UK by Chas & Dave called Rabbit which was about people endlessly rabbiting on.
