Robin intercoms do not have built-in 4G connectivity.
However, they can be used in combination with an external 4G router. In this type of setup, the intercom is connected with an Ethernet cable to the 4G router. This allows the router to provide internet access through a mobile network.
This setup has been tested with various 4G routers and the intercoms work reliably when properly configured. The functions and operation of the intercom is the same as if it is connected to a standard wired network.
What to consider when using 4G
A stable 4G signal is essential for reliable performance of Robin intercoms in this setup. Consider the location of the installation and the general signal quality in the area.
We recommend the use of a high-quality 4G router with an external antenna, especially in locations with weaker signal strength.
In addition, you should ensure that the network configuration, such as NAT and firewall settings, support SIP communication as this is essential for the correct operation of the Robin intercom.
