Information
Definition
A cellular modem connects a charger to mobile data networks such as 4G or 5G. It is normally considered alongside site connectivity, router/modem configuration, signal availability and ongoing remote support.
Why it matters
It is important for public, fleet and remote sites where fixed broadband or Wi-Fi may be unavailable or unreliable. For UK users, it affects whether a charger can remain connected reliably for authorisation, payments, diagnostics and software updates.
