What is Wireless Fidelity 6 (WiFi 6)?

Computer NetworkInternetMCA

Wi-Fi stands for “Wireless Fidelity.” It can define Wireless LAN (WLAN) products that are based on the IEEE 802.11 standards. Wi-Fi work with both single carrier direct-sequence spread spectrum radio technology and multi-carrier OFDM (Orthogonal Frequency Division Multiplexing) radio technology.

The next generation of the Wi-Fi standard is Wi-Fi 6. It is also referred to as 802.11ax. It is the newest step in a route of nonstop innovation. The standard constructs on the strengths of 802.11ac while inserting effectiveness, flexibility, and scalability that enables new and existing networks increased speed and space with next-generation applications.

Wi-Fi authorizes products via a set of created test procedures to make interoperability. Those manufacturers that are members of Wi-Fi Alliance whose products move these interoperability tests can indicate their products with the Wi-Fi logo.

Wi-Fi is provided to multiple extents under Microsoft Windows, Apple Macintosh, and open-source UNIX and Linux operating systems. Wi-Fi is the first high-speed fixed wireless technology to enjoy large deployment.

Hence, there exist today several wireless products based on Wi-Fi technologies that contain the approved IEEE 802.11a, b and g specifications, and the yet-to-be authorized 802.11n specification.

Wi-Fi as a high-speed wireless technology has enjoyed wide deployment, most prominently in hotspots around the world containing homes and offices, and more in cafes, hotels, and airports. Wi-Fi hotspots are very famous and have been approved for their ability to improve productivity for mobile corporate users.

Wi-Fi is finite by its coverage location and high-speed connectivity is only applicable considering a user remains within the area of the wireless access point, which is optimally inside 100m.

The Wi-Fi architecture includes a base station to which wireless hosts are linked to access network resources. The base station is answerable for sending and receiving data to and from the wireless host that is associated with the base station.

The relation between the host and the base station is the wireless communication connection. This communication link is answerable for data transport among the base station and the hosts. The main strength of Wi-Fi is its simplicity and ease of deployment given that it uses an unlicensed radio spectrum.

WiFi enables users to be mobile for up to 100m from the base station and can have access to the network. It can also the cost for rolling out this wireless solution is low because no expensive wiring is needed.

As a hooked broadband access technology, Wi-Fi has its vulnerability. The user can only use the technology within the boundaries of 100m radius thus specifying the method of mobility.

Also, the fact that the technology operates in the 2.4 GHz band which does not require any licensing renders it susceptible to interference from other devices such as Bluetooth, cordless phones, etc.
