| Shared goals of 5G and Wi-Fi 6 include increased bandwidth and network speeds, as well as low latency. Both 5G and Wi-Fi 6 aim to improve upon their respective former generations and enhance UX. Yet, with all their similarities, the two technologies have key differences that make them complementary to each other and offer alternate connectivity options for organizations.Authentication. 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.Network security. Security has been a major 5G concern for experts, due to potentially high costs to ensure 5G network security, as well as increased vulnerability concerns. However, 5G will introduce several security concepts, including security anchor functions, subscription permanent identifiers and subscription concealed identifiers. These functions can enable seamless and secure device reauthentication as a device travels between networks, which former cellular generations couldn`t guarantee.Use cases. Where and how organizations deploy cellular and Wi-Fi technology are other key differences between 5G and Wi-Fi 6. Traditionally, Wi-Fi is better suited to indoor wireless coverage, and Wi-Fi 6 will maintain this. Other Wi-Fi 6 use cases include increased support for IoT devices and high-density wireless service for locations such as stadiums and sports venues.As for cellular, 5G is better suited to outdoor use cases, such as autonomous vehicle support. In addition, 5G also aims to support mobile backhaul and fixed wireless access use cases. For organizations that turned toward 4G and LTE for backhaul use cases, 5G aims to improve that connectivity, as well as bring cellular into the fixed wireless space. -- ???????? | |||
