| + | [* icon_note] The true innovation in the smart meter is its ability to relay power consumption statistics without direct contact from a meter reader. It accomplishes this by sending encrypted signals on the 900 MHz radio spectrum. The antenna can be seen on the rear side of the board near its bottom edge. |
