Information
Definition
4G is a mobile network generation commonly used for EV charger cellular data connectivity. It is normally considered alongside site connectivity, router/modem configuration, signal availability and ongoing remote support.
Why it matters
It is widely used for public and commercial chargers where wired internet is unavailable or where mobile backup is needed. For UK users, it affects whether a charger can remain connected reliably for authorisation, payments, diagnostics and software updates.
