SmartGridElectronics.Net is reporting that some smart meters are causing RFI. In an article published today, they say:
The smart meters that Central Maine Power Company (CMP) is installing throughout its territory pursuant to Commission approval are causing radio frequency interference with some customers’ electrical appliances, personal computers, and communications devices. To date, over 200 customers have contacted CMP about problems with a variety of appliances and devices including phones (cell, cordless, and landline), answering machines, Internet routers and wifi, personal computers, TVs, garage doors, fire alarms, clocks and even electric pet fences. The most common problem is interference with wireless internet routers, because they use similar radio frequencies. The problems can often be resolved by simply changing a setting on the device. Other concerns include malfunctioning phones, Internet routers crashing or freezing, damage to computer hard drives, static and clicking sounds on communication and computer gear, inability to stream Netflix, failure of TV remote, and other appliance malfunctions.
Fortunately, they’re not using BPL for this project. They’re using some kind of wireless networking in the 2.5 GHz band. Even so, it makes you wonder if anyone ever did any EMI/RFI testing on these devices.
