| Many of the differences between Wi-Fi 6 and 5G stem from the difference between their technology types. 5G is a cellular technology that uses base stations, small cells and radio signals to transfer data and provide connectivity to end-user devices. 5G typically covers a large geographic area. Wi-Fi is a wireless LAN technology that uses routers, access points and radio signals to connect devices in a limited range.While Wi-Fi technology`s unlicensed bands don`t require permission to use, access to the Wi-Fi network itself does. To access a Wi-Fi network, users typically require a service set identifier -- or network name -- and password. In addition, Wi-Fi 6 introduces a new authentication type called Simultaneous Authentication of Equals for added protection against bad actors.Security has been a major 5G concern, due to potentially high costs to secure 5G networks and increased vulnerability concerns. However, 5G introduces several security concepts, including security anchor functions, subscription permanent identifiers and subscription concealed identifiers. These functions enable seamless and secure device reauthentication as a connected device travels between networks, which former cellular generations couldn`t guarantee.Wi-Fi is typically cheaper to build and use. Unlicensed spectrum doesn`t require license fees to use, and Wi-Fi devices are typically more affordable than other networking equipment. 5G offers high-speed connectivity but for higher prices. Most operators have to build their 5G infrastructure from the ground up, which requires heavy investments in equipment and components. They also have to purchase the spectrum to use in their mobile networks.Where and how organizations deploy cellular and Wi-Fi technology are other key differences between Wi-Fi 6 and 5G. Traditionally, Wi-Fi is better suited to indoor wireless coverage, and Wi-Fi 6 maintains this. Other Wi-Fi 6 use cases include increased support for IoT-connected devices and high-density wireless service for locations such as stadiums and sports venues. -- ???????? | |||
