With iOS 16, the iPhone now has cellular iCloud backups and LTE

Similar to iOS 15, Apple has updated iOS 16 with a new feature that enables users to backup their devices to the cloud over both 5G and an LTE connection.

The new backup features for iOS 16 and iPadOS 16 are described in the release notes of Apple’s second developer beta of iOS 16:

Users of iOS 16 can now backup their iPhone over an LTE cellular connection in addition to a 5G or WiFi connection.

Customers who are using iOS 15 already have the choice to backup their devices over a cellular connection, but it is only compatible with 5G right now.
