Smart meters run on two frequencies. The frequency communicating to the electric meter is 900 MHz (megahertz). If the premise also has a gas meter, the frequency from the electric meter to the gas meter is 2.4 GHz (gigahertz).

The electric meter frequency is similar to a cell phone and the gas meter frequency is similar to a computer router. Neither device will interfere with any wireless devices in the home and it is highly unlikely that the relatively weak fields produced the meter would interfere with the operation of a medical device.

While very similar to the existing electric meters, there is one big difference in the appearance of the new smart electric meter: an easy-to-read digital display instead of the spinning wheel or dial that many customers have today.  For those customers, this will be the only obvious difference between the appearance of the old and the new meter. 

The old meters are recycled.  Any newer, electronic meters utilities replace (such as solid state meters and OMR – offsite meter read – meters) are refurbished, tested and recycled back into the meter population until smart meters are installed in the area in which they are recycled. The older, electromechanical (dial) meters that are replaced are dismantled and all their components – such as aluminum, copper, glass et cetera – recycled.
