Overview
The Inventory Master IoT base station gateway based on low power LoRaWAN protocol, which can provide low power, mobile and safe local bidirectional communication service for IoT devices. LoRaWAN can simplify the interconnection of device, user and network, as well as provide standard designed to be used in long range star network architectures; it can achieve message delivery between front-end device and central network server. Connected to the network server via standard IP connections while front-end devices use single-hop wireless communication to one or many gateways. The communication between front-end devices and established by different channels and data rate, which can be negotiated in advance. In order to save the battery life, can maximize the power saving by implementing ADR (Adaptive Date Rate). With our IoT technology and our base station gateway, users can then have their own IoT control system to achieve customized smart services, which will be widely applied in the fields of smart parking, smart fire-fighting, energy management, asset tracking, smart grid, industry 4.0, smart agriculture and etc. in the future.
Features
