Introduction
The RAK811 is a wireless transparent communications module, based on the Semtech SX1276. LoRa technology utilizes a spread spectrum modulation in the Sub-GHz band to enable long range (greater than 10 miles) coverage, low power consumption (up to 10 years battery power), high network capacity (up to 1 million nodes), robust communication, and localization capability. With strength of RF hardware capability by RAK, RAK811 communication distance maintain to 3000m with improve receiver sensitivity.
Moreover, RAK811 fully supports and conforms to the specifications of LoRaWAN Class A&C protocol, facilitating an easy access to LWPA IoT platforms, such as Activity.
