The OS pulls info to feed google/samsung apps at times to keep them refreshed, such in case your contacts and etc. They are tied to TW which is tied with android. Also, clock widgets. They pull time from the system which pulls from the network to keep it accurate whether you're on cellular or wifi. It could also mean you have apps set only to update through wifi and it's just displaying s system.
Nothing to worry about.
