Innovative industrial secure Cellular LTE router WR322GR Series is designed for IIoT applications by dual-radio high-speed LTE routing and WLAN networks. Dual RS232/422/485 ports with Modbus support brings sensor and meter data to cloud wirelessly. The WR322 router supports LTE to WLAN redundancy and LTE/WLAN auto offload to guarantee continuous connections. To safeguard cybersecurity, security features such as Firewall, OpenVPN, GRE tunnel are supported. The embedded MQTT and RESTful API enables instant public cloud integration such as AWS or Azure. The private cloud platform ThingsMaster and ThingsMaster OTA can also be set up for an instant and secured access to receive data or manage devices remotely.
