Pacific Gas and Electric Co.’s wireless SmartMeters are designed to communicate directly with the utility, eliminating the need for meter readers.
Turns out they do a lot of talking.
According to a document PG&E filed with the California Public Utilities Commission this week, the typical meter sends out almost 10,000 radio-frequency signals per day.
The signals are very, very brief. Add them together, and the meter’s total transmission time equals a little more than 45 seconds per day. And the signals’ peak energy level falls well within federal standards, according to a PG&E spokesman.
