2G and 3G will be phased out by 2033 under plans to help bring in new telecoms suppliers to build the UK’s 5G networks

How many smart meters and pdqs are affected by this?

Source is above, there are many articles across the internet on this, but the source is worth reading.

At my age i don't think it'll be an issue.

Nor me !

Might it not always apply to those?  In my area there seems to be a mast specifically for smart meters which is strange as we have good coverage on all networks.

I'm aware O2 have deployed LTE-M :

What's the mast you have locally?

It will be a standard smart meter mast. They are dotted all over the place.

Arqiva who own/operate the UK terrestrial tv (Freeview) transmitters also own much of the smart meter network.

Edit: seems Arqiva sold its telecommunications business to Cellnex in 2019. No idea if this includes the smart meter masts.

It seems in US they will be shutting down the 3g networks in 2022.

https://www.washingtonpost.com/technology/2021/09/30/3g-networks-ending/

All of the major cellphone carriers — AT&T, Verizon and T-Mobile — are planning to shut their older 3G networks in 2022. Like millions of people in the United States who use 3G phones and other 3G devices, she will have to buy a new device if she wants to text, make calls or even reach 911.

I found out via a CPAP review channel, as I use a device myself daily. A guy had wrote a message to the video maker and it was concerning the modems inside the devices that are 2g/3g. The modem allows the doctor to see the current stats of the machine as well as change settings without the patient having to go to hospital.

The modem isn't vital. But the CPAP makers will have to figure out how to upgrade the modem board to 4g for them to continue to have that functionality.

I believe most of the operators in the UK are working to a similar end date for their 3G networks.

Good point about the CPAP machine though, we have one as well and it will be interesting to see how they deal with this.

We only get 2G or maybe 3G  (if the winds in the right direction and it's a Tuesday ) That's if we go up the hill outside of the village, In the house Nill.

I have excellent 4G in most parts of the house upstairs and some parts downstairs though in some places my iPad drops down to 3G if I’m reading it correctly. But down the hill, my neighbours have nothing at all. When I lived in the house on the seashore over the summer of 2003, all I could get down there was just barely enough signal for SMS and even then only in the bathroom velux roof window.

That's kinda the point though, if you turn off 2G/3G and re-use those frequency bands for 5G, reception should be better.

Of course that's a big "if" and not much help for people who only need a 2G/3G device, of which there are still loads on the market that will become doorstops..

I can get a 4G USB ‘modem’ for use in my Firebrick router as an emergency failover link. Currently I have a 3G USB modem. So when I have to get rid of the 3G device, then I will find as I already have done, that although the 4G device might reasonably seem a plug-in replacement for the working 3G modem, in fact the 4G device isn’t a modem at all but rather an annoying IPv4 NAT router which does not provide the straight-through bridging functionality that I need; it’s incompatible with the correct, usable 3G modem.

So am I going to be truly stuffed in this respect in the far, far distant future, or will someone come out with a truly equivalent 5G/4G replacement for the 3G USB modem? Will presumably be looking for 6G devices by then?

[Chrysalis]

Well at least they not phasing out 4g, as 5g coverage is very very poor.

My city is pretty much almost 100% indoor and outdoor 4g coverage.

5g is maybe 5% coverage at best for indoor use.

[Alex Atkin UK]

I just hope they DO use the 2G/3G bands for 5G, rather than cheaping out and selling the spectrum off.

Quite a lot I think in the Central and South regions of the UK, because Telefonica from 2013 use the O2 2G network to provide the smart meter connections to the Smart Meter DCC, see https://news.o2.co.uk/press-release/telefonica-uk-signs-1-5bn-smart-meter-deal/#:~:text=On%2012%20September%202013%2C%20Telef%C3%B3nica,of%20approximately%20%C2%A31.5%20billion.

The DCC say that they are looking in to it, following the HMG announcement in December 2021, see https://www.smartdcc.co.uk/news-events/2g-sunset-looking-into-the-future-of-connectivity/ and say that they will rely on 3G out towards 2033 because they have to cover 99% of landmass of UK.
