Freescale has sub-1-GHz ultra-low-power smart radio
Freescale demonstrated the radio at ESC Boston last week. The MC12311 can connect smart meters to remote displays that show consumption data and thermostats that help control energy use.
Pike Research predicts 535 million smart meters will be deployed worldwide by 2015, of which approximately 50 percent of them will use wireless mesh technology. The MC12311 can also be tied to ultra-low-power medical sensors worn on the body, wireless building sensors that detect temperature and humidity, garage door openers and general cable/wire replacement.
The radio’s very low power is suitable for battery operated devices, according to Freescale: the M12311 has low-power features such as 100 nA with radio configuration retention, 16 mA Rx current, 20 mA Tx current at 0 dBm and 33 mA Tx current at +10 dBm. The MC12311 platform supports multiple sub-1 GHz standards including Wireless M-Bus, 802.15.4g and other proprietary offerings.
