Dont; forget this 1000 would actualy be millions as most housholds have
electricity and teh plan is for tehm all to be smartmeters.

It doesn't take much to realise that you can take the readings every 30
minutes, store them locally, then upload a compressed bundle say once a
week or month, cutting out a ****load of handshaking ...

Yes you can but that won't tell the electric company how much leccy your using NOW or at any other time, that is the point.
You don;t need to upload every 30 mins or even every hour or even everyday.






So see if yuo can calculate the sort of bandwidht needed to up load
millions of users data within a few minutes.
Trivial sums

Yep and you'll find some interesting numbers that are trivial but significant especailly inn rural areas, It'll be a bit like the old style christmas post.
