| Explanation & Hint:
Mobile devices use Wireless Wide Area Network (WWAN) or cellular Internet access technology. WWAN requires using an adapter to link to a cellular provider network through the nearest base station or transmitter. WWAN adapters can be internally or externally connected by USB. The bandwidth available over WWAN connections depends on technologies supported by the adapter and the transmitter, such as 3G or 4G. Connection to the WWAN is automatic once the adapter and adapter software are installed. |
