AG-221


Dual LAN cellular IoT gateway


Coming Soon!

  • OpenWRT system with custom script support
  • Dual Ethernet, WiFi, 4G LTE, GPS and RS485
  • Additional 512MB memory as overlay
  • More than 6500 ready applications

AG-221 is 4G LTE cellular gateway with 2 ethernet ports, WiFi, RS485, digital inputs working on OpenWRT system. It can connect in multiple ways to the Internet with dual SIM capability and a range of advanced functions for mission critical IoT or M2M applications. AG-221 also support MQTT protocol for cloud application and Modbus TCP/IP or RTU for industrial applications. It supports multiple VPN providers and is therefore ideal for remote PLC management and industrial automation monitoring.
