Introduction Specifications Application Specifications

Introduction

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.

LoRa Technology

LoRa technology applies physical layer or wireless modulation to build long-distance communication link, based on LEF SS modulation, it maintains the same low power consumption as of FSK modulation, but significantly prolongs communication distance (less cost in commercial uses).

LoRaWAN defines communication protocol and system architecture of networking, aiming at some core requirements of IoT, such as safe two-way communications, mobility and local service. The technology does not require local complex configuration to allow seamless interoperability among smart devices, releasing the operating authority to the users, developers and enterprises of IoT

LoRaWAN Benefits
