A wireless wide area network (WWAN) connects mobile devices to the internet via mobile phone masts. Unlike a WLAN, a WWAN offers a greater range, particularly outdoors, and is operated by mobile phone providers. Radio network types used include GSM, UMTS, LTE and 5G.

WLAN vs. WWAN

Both WLAN (wireless local area network) and WWAN (wireless wide area network) are wireless networks, but they differ in terms of range and usage. WLAN is typically used at home or in the office, connecting devices to the internet via a router — ideal for short distances. WWAN, on the other hand, uses the mobile network (e.g. LTE or 5G) and offers internet access over long distances — for example, when travelling with a SIM card. It is particularly useful when WLAN is unavailable.
