Wireless networks of different sizes deliver data in the form of telephone calls, web pages, and video streaming.
WWAN connectivity allows a user with a laptop and a WWAN card to surf the web, check email, or connect to a virtual private network (VPN) from anywhere within the regional boundaries of cellular service.
A WWAN may also be a closed network that covers a large geographic area.
For example, a mesh network or MANET with nodes on buildings, towers, trucks, and planes could also be considered a WWAN.
A WWAN may also be a low-power, low-bit-rate wireless WAN, (LPWAN), intended to carry small packets of information between things, often in the form of battery operated sensors.
