Here is one companies Smart Meter implementation.
Their systems have been installed in both Canada and USA.
220 (higher power) and 900 MHz (lower power) packet radio links.

get users to use less power at peak times they can avoid costly system
upgrades to supply the peak power required. You know who pays for the
