RM1xx Series - LoRa + Bluetooth v4.0 Enterprise IoT modules

The RM1xx series of modules offer a powerful, convenient solution for long-range Enterprise IoT (EIoT) deployments, combining Bluetooth® v4.0 with LoRaWAN™, the emerging standard in Low Power Wide Area Networks (LPWAN), into one module.

Laird RM1xx modules aggregate and transmit data from Bluetooth® Smart (BLE) devices and sensors over LoRa® to gateways as far as 15 km (~10 miles) away. This bridges the personal area network to the wide area network in a unique way. The RM1xx will be LoRa® Alliance certified and fully interoperable with any LoRaWAN™-adherent gateway.

Key features:

  • Designed for the EIoT - Innovative combination of BT™ v4.0 and LoRa® makes the RM1xx the bridge between Bluetooth Smart devices and a network that intelligently uses their data.
  • Ultra-low power usage schemes - Allows years of use on a single battery.
  • Laird's unique smartBASIC language - Makes it extremely easy to create event-driven, hostless applications.
  • Upgradable firmware - Prepare for the future with access to feature and security updates.
  • Compliant with FCC, CE regulations - Available as the RM186 (CE) or RM191 (FCC).
