Innovative industrial secure LTE router WR322A-M12 Series is designed for IIoT applications on railway by dual radio high-speed LTE routing and Wi-Fi networks. LTE Cat.4/6 technology provides up to 300 Mbps data rate, while IEEE802.11ac Wi-Fi delivers up to 866Mbps high throughput. RS232/422/485 and DIO devices are able to connect the cloud over cellular and Ethernet network. Cyber redundancy includes wireless auto-offload, LTE/WAN backup, redundant SIM ensure the best connectivity. The embedded MQTT and RESTful API enables public cloud integration such as AWS or Azure. The private cloud platform ThingsMaster can also be set up for instant and secured access to track location and monitor data over cloud.
