Connect to Wi-Fi Easily
Overview
Wi-Fi, a shorthand for wireless fidelity, represents a suite of wireless networking technologies, mainly known as 802.11 networks, including 802.11b and 802.11a, dual band. The term "Wi-Fi" was coined by the Wi-Fi Alliance, an organization that certifies products to ensure quality and compatibility.Wi-Fi Certification
Products analyzed and approved by the Wi-Fi Alliance receive the "Wi-Fi Certified" label. Initially, Wi-Fi referred specifically to the 2.4 GHz 802.11b standard. It quickly gained popularity, spreading access points across the United States. These standards are globally embraced, allowing devices like laptops and PDAs to connect wherever a Wi-Fi hotspot is available.Wi-Fi Standards and Speed
There are three main Wi-Fi standards that indicate connection speed. Both 802.11a and 802.11b can achieve speeds of 54 Mbps, with 802.11a offering additional capabilities. Although 802.11b is the most common, supporting speeds of 11 Mbps, faster standards are continually emerging. Despite these differences, all Wi-Fi standards generally support broadband connections.The Rise of Wi-Fi
Wireless fidelity is becoming as ubiquitous as electric outlets and phone lines. It offers significant convenience and boosts productivity, especially for workers in Wi-Fi-enabled offices. Originally designed for wireless devices, Wi-Fi is now widely used for internet access, enabling computers to connect without wires. Travelers can increasingly find Wi-Fi in airports, coffee shops, cafes, malls, and hotels globally.How Wi-Fi Works
Wi-Fi enables wireless networking by transmitting a global internet connection via radio waves. These waves, emitted by antennas, are received by Wi-Fi-enabled devices. Once a device detects a signal within a network's range, it connects to the internet using a Wi-Fi card. Users may need to log in or enter a password, depending on network security settings.Wi-Fi Security
Wi-Fi faces several security challenges. Wired Equivalent Privacy (WEP) is used to secure data on physical and data link layers, aiming to protect transmissions between points. Unlike wired LANs, where networks are typically confined to buildings, wireless LANs are more vulnerable because radio waves are easier to intercept. WEP's vulnerability partly stems from organizations not regularly changing shared keys, which can be problematic if these keys are compromised.By understanding these aspects of Wi-Fi, users can better appreciate the technology that powers their wireless connections, as well as the importance of maintaining robust security practices.
