The RAK811 is a wireless transparent communications module, base 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.
☼ LoRaWAN protocol supported, global license-free ISM band, full certification by region. ☼ Lora Point to Point communication, Activation by OTAA/ABP. ☼ Easy to use, UART interface, serial port AT command, baud rate and air rate online change supported, simple ASCII command set. ☼ Maximum output power 100MW (20dBm), adjustable from 5 to 20dBm. ☼ High sensitivity,-148 dBm, enabling extremely long range connectivity. ☼ Long range - greater than 15 km. ☼ High capacity of up to 1 million nodes ☼ Low power consumption, 500nA on standby, in-air wake-up supported. ☼ Multi-channel, dual data buffer (256byres each). ☼ LoRa/FSK/GFSK/OOK modulation, bidirectional 2 way communications. ☼ Long battery life - over 10 years. ☼ LoRa technology is capable of demodulating 20 dB below noise level, significantly improving immunity to the interference when combined with integrated forward error correction.
