4G Router is a device that, connected to a fixed telephone or to the PSTN input terminals of a PABX or autodialer, allows you to make and receive calls over the 4G LTE/UMTS/GSM network.

4GRouter comes with built-in backup batteries and 2 relays output which can be activated either locally or remotely via SMS.It also has the following features:

  • LAN/Wireless access point to offer Wi-Fi/cabled connectivity to connected devices
  • Dynamic DNS client to allow the user to remotely access (using the public Internet) the router itself and all the devices connected to it
  • Data transmission through standard RS-232/RS-485/CAN-bus.

For correct operation the SIM card must be enabled for voice and data traffic.
