Featured gateways
Hardware for every connection point.
Compare models by network, interface and project fit, then send your requirements for a clear engineering recommendation.
One system for networking, sensing and device access.
For industrial IoT projects, the gateway is the bridge between legacy field equipment and modern cloud platforms. Net Join IoT provides cellular gateway models for data acquisition, transparent transmission, protocol access and remote O&M.
Connect distributed field devices to cloud platforms, SCADA systems or private servers.
Use LAN, WAN, RS485, digital I/O, SIM and antenna interfaces according to the selected model.
Support smart pole, power cabinet, water management, machine monitoring and outdoor equipment projects.
Provide logo, label, port map and firmware customization for project-based orders.
