• Wireless connection – the station connects to a 2G/3G mobile network with the use of
additionally built-in router. The contracting entity signs a contract with the mobile
network operator to acquire a unique APN (private network in the mobile operator's
network). The contracting entity and the mobile operator must properly direct data
traffic between the station operator's network and the mobile operator's network with
the use of firewalls. In the case of clustering of charging stations, only the first charging
station needs to be equipped with a router, while the other stations can be connected
to it with a UTP/SFTP cable.
• Connection to an existing network in the facility on the location of the charging station.
In this case, the data traffic is directed through the existing internet connection and the
contractor must install proper network equipment (router/firewall) to ensure the safety
of data traffic.
