Question: what is the difference between wifi and wwan?
Answer: WLAN and WWAN both connect you to the Internet wirelessly, but they use different technology to do it. WLAN is intended for “local” use (the “L” in WLAN). ... WWAN is a mobile broadband3 option that covers a “wide” area (the “W” in WWAN). You may have heard it called a “3G” or in some areas a “4G” network.
