I am not familiar with the protocols.  I hear the KHz transmissions occur 
about once per hour, I talked with a meter reader about the 900 MHz 
equipment, he has a small data terminal he carries in the vehicle.  Normally 
it interrgotates meter as he drives on the typical monthly round, I ran into 
him in an office building coming out of the sub-panel room, he said he 
couldn't read the meters from his truck.

Now that I think about it, the low-frequency system is called "TWACS", a 
quick search on the web shows a frequency range of 30-500 KHz.

Is that some kind of Zigbee protocol then?
