An anonymous reader writes: MIT Technology Review reports that French company Sigfox will soon roll out a cellular data network in the San Francisco Bay Area aimed exclusively for low-bandwidth, low power devices such as household appliances and sensors. It's the U.S. debut for a technology already in use in France. The network uses the 900 MHz unlicensed spectrum used by cordless phones. Sigfox says that and their technology's very low bandwidth makes it possible to connect devices significantly more cheaply than with conventional cellular modems and service.
