This object reports the cellular service type the modem is presently using, again drawn from the 2G/3G/4G-LTE capability set. An admin monitors this in real time to confirm whether a site is actually getting the higher-speed service tier it's paying for or has silently dropped to a slower fallback technology. For example, seeing this value change from LTE to a lower tier during business hours would prompt an admin to investigate local tower congestion or coverage problems.
