About wifi

Wi-Fi, short for Wireless Fidelity, is a wireless networking technology that enables devices such as computers, smartphones, tablets, and other equipment to connect to the internet and communicate with each other without the need for physical cables. It utilizes radio waves to transmit data between devices and a wireless access point, typically a router, facilitating seamless connectivity within a local area network (LAN). ​GeeksforGeeks+2GeeksforGeeks+2Cisco+2

Key Components of Wi-Fi Networks:

• Wireless Access Point (WAP): A networking device that allows Wi-Fi-enabled devices to connect to a wired network. It acts as a central hub, broadcasting the Wi-Fi signal for devices to detect and join. ​GeeksforGeeks

• Wireless Router: Combines the functions of a router and a wireless access point, managing both internet traffic and wireless connections for devices within the network. ​Cisco

Wi-Fi Standards:

Wi-Fi operates based on various IEEE 802.11 standards, each introducing improvements in speed, capacity, and security:​Cisco

• 802.11ac (Wi-Fi 5): Introduced in 2013, it delivers higher throughput to wireless local-area networks (WLANs) compared to its predecessor, 802.11n. ​Cisco

• 802.11ax (Wi-Fi 6): Ratified in 2020, Wi-Fi 6 enhances efficiency, flexibility, and scalability, providing faster data transfers, lower latency, and improved performance in environments with numerous connected devices. ​WIRED+2Cisco+2Cisco+2

Advantages of Wi-Fi:

• Mobility: Enables users to move freely within the network coverage area without losing connectivity.​GeeksforGeeks

• Convenience: Simplifies the process of connecting devices to the network without the need for physical cables.​GeeksforGeeks

• Scalability: Easily accommodates additional devices without significant infrastructure changes.​Cisco+5GeeksforGeeks+5Cisco+5

Security Considerations:

Implementing robust Wi-Fi security measures is crucial to protect devices and networks from unauthorized access and potential threats. Without proper security, wireless networks can be vulnerable to unauthorized users within range of the signal. ​Cisco

Wi-Fi technology continues to evolve, offering enhanced capabilities and supporting a growing number of devices and applications in both personal and professional settings.
