Product Overview

The RM191-SM-01 is an intelligent LoRa/BLE module (915MHz LoRa for US / Canada) featuring smartBASIC. The RM191 module offers a powerful, convenient solution for long-range Enterprise IoT (EIoT) deployments. Laird innovatively combines Bluetooth v4.0 with LoRaWAN, the emerging standard in Low Power Wide Area Networks (LPWAN) into one module. RM191 module aggregate and transmit data from Bluetooth Smart (BLE) devices and sensors over LoRa to gateways as far as 15Km (approximately 10miles) away. This bridges the personal area network to the wide area network in a unique way. The RM191 is LoRa Alliance and Bluetooth SIG certified and fully interoperable with any LoRaWAN adherent gateway.
