Re: Promises, promises
I got a free upgrade to 4G on 3 network and at home in the evening I've seen 40mbit speeds up and down - amazing speed!
2 miles away in one of the financial districts I struggle to get 1mbit and in the new office location I don't even get a signal at all, so it's pretty pointless most of the time.
You put 100,000 people/phones in a 2km square area and it just doesn't have the throughput it needs on the backend, doesn't matter if it's 3G, 4G or 5G, the higher number just makes you more annoyed it's not working as marketed. Holiday day trips to lightly populated Med' islands show how decent even 3G is when it's not over subscribed.
Oh and on the IoT... I love the quote I read on t'internet - "my boiler won't turn off because it can't see the internet". I would laugh hard at that except the landlord controls the heating for the flats from his phone....
