1 Introduction WM1110 is a fusion positioning module based on LoRaWAN communication technology. The hardware mainly integrates Semtech LR1110 Edge chip and Nordic’s Nrf series Bluetooth chip, which can provide a variety of positioning technologies including Bluetooth positioning, LP-GPS and WIFI positioning. It is an ideal platform for developing various tracking product solutions. 1.
2 Description WM1110 is embedded with high-performance Semtech LR1110, which is very suitable for the design of various IoT nodes. Ultra-low power platform that integrates a LoRa® transceiver, long range FHSS modulator, multiconstellation scanner, and passive Wi-Fi AP MAC address scanner targeting asset management applications. The LR1110 solution utilizes Semtech’s LoRa Cloud™ Ceolocation capabilities, to significantly reduce power consumption by determining asset location in a Cloud-based solver. 2.
