Cellular

Cellular networking refers to wireless data communication over mobile telephone networks — the same infrastructure used for voice calls and SMS. Modern cellular standards (LTE, 4G, 5G) provide broadband-speed internet access over radio links managed by carriers such as AT&T, Verizon, and T-Mobile. A cellular modem connects to the nearest cell tower and exchanges data over the carrier’s wide-area network, providing internet connectivity without a wired connection.

Because cellular coverage is independent of local wired infrastructure, it is commonly used as a backup communication path: if a broadband connection fails, a device with a cellular modem can continue to reach the internet over the carrier network.

The Enphase IQ Gateway includes a built-in cellular modem. If the home’s primary internet connection is unavailable, the gateway falls back to cellular to continue reporting solar production data to Enphase’s cloud monitoring platform.
