Explain what the function of a WWAN network is in the context of the transmission limitations of Wi-Fi.
What will be an ideal response?
Although Wi-Fi is great for communicating with a nearby router, its transmission limitations mean it cannot provide mobile Internet access from a car or outdoor site far from any base station. To handle this type of wireless communications, we need a different type of network called a wireless wide area network (WWAN). In this type of network, the computer (often a tablet or smartphone) transmits messages to a remote base station provided by a telecommunications company, which may be located many miles away. The base station is usually a large cellular antenna placed on top of a tower or building, providing both long-distance voice and data communication services to any system within sight of the tower. One of the most popular wide area wireless technologies is called 4G. It offers voice services as well as data communication at rates of 50 to 500 Mbps, with peak speeds reaching 1Gbps.
