Wi-Fi, a technology that allows electronic devices to connect to a local area network (LAN) wirelessly, has become a cornerstone of modern communication. It enables users to access the internet and share data without the constraints of physical cables. The significance of Wi-Fi extends beyond mere convenience; it supports various applications ranging from personal use, such as streaming and gaming, to professional environments where reliable connectivity is crucial for productivity. As the demand for high-speed internet continues to rise, Wi-Fi plays an essential role in facilitating seamless communication and access to information globally.

What is Wi-Fi

Wi-Fi, short for Wireless Fidelity, refers to a set of standards for wireless local area networking (WLAN) that allows devices to communicate without direct cable connections. It operates on radio waves and is based on the IEEE 802.11 standards. Wi-Fi technology enables devices such as smartphones, laptops, tablets, and smart home appliances to connect to the internet or communicate with each other over a wireless network.

Typically, Wi-Fi networks consist of a router that acts as a central hub, transmitting signals to connected devices within its range. The convenience of Wi-Fi allows users to move freely within the coverage area while maintaining connectivity. Additionally, Wi-Fi supports multiple devices simultaneously, making it ideal for both home and office environments where numerous gadgets require internet access.

How does Wi-Fi work

Wi-Fi technology operates using radio waves to transmit data between devices. The process begins when a device, such as a smartphone or laptop, sends a request to connect to a Wi-Fi network. This request is received by a wireless router, which is connected to the internet through a wired connection.

The router then communicates with the device using specific frequencies (typically 2.4 GHz or 5 GHz). Data is transmitted in packets, which are small chunks of information that are sent over the airwaves. Each packet contains the destination address (the IP address of the receiving device) and the source address (the IP address of the sending device).

Once the data packets reach their destination, they are reassembled into their original format by the receiving device. This process happens rapidly, allowing users to browse the internet, stream videos, or play online games without noticeable delays. The efficiency and speed of Wi-Fi technology have made it an integral part of daily life.

Different Wi-Fi standards (802.11)

Standard	Maximum speed	Frequency bands	Year introduced
802.11b	Up to 11 Mbps	2.4 GHz	1999
802.11a	Up to 54 Mbps	5 GHz	1999
802.11g	Up to 54 Mbps	2.4 GHz	2003
802.11n	Up to 600 Mbps	2.4/5 GHz	2009
802.11ac	Up to 3.5 Gbps	5 GHz	2013
802.11ax (Wi-Fi 6)	Up to 9.6 Gbps	2.4/5 GHz	2019

This table outlines various Wi-Fi standards and their capabilities, illustrating how advancements have led to increased speeds and improved performance over time.

Types of Wi-Fi deployments

Wi-Fi deployments can be categorised based on their architecture and management style:

Centralised deployment: In this model, all access points are managed from a single location or controller.

Converged deployment: Combines both wired and wireless networks under one management system.

Cloud-based deployment: Utilises cloud computing resources for managing Wi-Fi networks.

Distributed deployment: Each access point operates independently without centralised control.

These deployment types cater to various organisational needs, ensuring efficient network management based on specific requirements.

Security protocols in Wi-Fi networks

Security protocols are crucial for protecting data transmitted over Wi-Fi networks:

• WEP (Wired Equivalent Privacy): An older protocol that provides basic security but is now considered insecure due to vulnerabilities.
• WPA (Wi-Fi Protected Access): Introduced improved security features over WEP but has been succeeded by more advanced protocols.
• WPA2: Offers stronger encryption methods using AES (Advanced Encryption Standard) and is widely used in modern networks.
• WPA3: The latest security protocol that enhances protection against brute-force attacks and improves security for open networks.
• These protocols ensure that data remains secure during transmission over wireless networks.

Wi-Fi security protocols (WPA, WPA2, WPA3)

Protocol	Encryption method	Key features
WEP	RC4	Basic security; vulnerable
WPA	TKIP	Improved security; still vulnerable
WPA2	AES	Strong encryption; widely adopted
WPA3	AES	Enhanced security; protection against dictionary attacks

Types of Wi-Fi network security devices

Firewalls: Protect networks from unauthorised access by filtering incoming and outgoing traffic based on predetermined security rules.

Intrusion Detection Systems (IDS): Monitor network traffic for suspicious activity and alert administrators about potential threats.

Access Control Lists (ACLs): Define which users or devices have permission to access certain resources within the network.

Wireless Intrusion Prevention Systems (WIPS): Specifically designed to detect and prevent unauthorised access points from compromising network security.

These devices play vital roles in safeguarding Wi-Fi networks from various security threats.

Benefits of modern Wi-Fi (Wi-Fi 6)

Modern Wi-Fi technology, particularly Wi-Fi 6 (802.11ax), offers several advantages:

Higher speeds: Capable of delivering speeds up to 9.6 Gbps, significantly enhancing user experience during high-bandwidth activities like streaming and gaming.

Improved capacity: Supports more simultaneous connections without degrading performance, making it ideal for environments with many connected devices.

Better efficiency: Utilises technologies like OFDMA (Orthogonal Frequency Division Multiple Access) for more efficient data transmission across multiple devices.

Enhanced range: Provides better coverage in larger areas due to advanced beamforming techniques that direct signals towards specific devices.

Lower latency: Reduces lag during online activities, improving responsiveness in applications requiring real-time interaction.

These benefits highlight why upgrading to modern Wi-Fi standards is essential for both personal and professional use.
