Laird's RM186/191 series of modules offer a powerful, convenient solution for long-range Enterprise IoT (EIoT) deployments. Laird innovatively combines Bluetooth v4.1 with LoRaWAN™, the emerging standard in low-power wide-area networks (LPWAN), into one module. The 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 RM186/191 will be LoRa Alliance certified and fully interoperable with any LoRaWAN-adherent gateway.
