RF315MHz

Laws of physics dictate that the 315 MHz frequency band carries data through materials, such as building walls, more efficiently than the higher 900 MHz and 2.4 GHz frequencies. When other range variables are held equal, 315 MHz RF modules yield longer indoor range (up to 4x the range of 2.4 GHz data communications). The 315 MHz band is less crowded than the unrestricted ISM bands. 2.4 GHz systems have to share air waves and do battle with high-powered signals originated from pervasive devices such as Wi-Fi routers, mobile phones, VoIP phones, microwave ovens and Bluetooth units. When high and low power transmissions share the same frequency, higher power outputs always win. EnOcean-enabled sensor networks are isolated from the crowded ISM air waves.
