The location of telecommunication towers in Australia is freely available. Why aren’t collectors in the meshed smart meter networks also within the public domain? Areas close to collectors may have higher levels of radiation than other areas in the meshed smart meter networks. Why should collectors fall under the radar?
Victorian power distributors CitiPower and Powercor Australia, Jemena and United Energy, along with Western Power in WA, Essential Energy and Endeavour Energy in NSW, and WEL Networks and Unison in New Zealand, have all elected to use smart grid technology from Silver Spring Networks.
Access Points are the lynchpins in the meshed smart meter networks. Don’t be mistaken by their innocent appearance. These are the devices which link wireless communications between all the smart meters in a given area and the utility. This means that Access Points aren’t just fulcrums for the 915 – 928 MHz microwave communications, but they also deploy other communications. For instance, CitiPower elected, in its rollout of smart meters, to use Telstra for its 3G ‘backhaul’ communications between Access Points and CitiPower.
Relays are an intermediary device used to extend microwave signals in a meshed network between smart meters (‘end points’) and the Access Point.
Pictures of a Powercor Access Point, seen from two different angles, follow. Have you spotted one of these devices in your neighbourhood?
