What is Wi-Fi and how does it work?
Wi-Fi is a technology that allows devices to connect to the internet or communicate with one another wirelessly using radio waves. It primarily operates under the IEEE 802.11 standards, which define protocols for wireless local area networks (WLANs). When you connect to a Wi-Fi network, your device communicates with a router, which acts as a gateway to the broader internet, converting data into radio signals that can be transmitted through the air.
The connection is established when a Wi-Fi-enabled device sends a request to the router. The router, upon receiving that signal, sends back the requested data. This two-way communication allows for high-speed internet access without the need for physical cables, making it more flexible and portable. Wi-Fi technology has evolved through various standards, each improving speed, range, and connectivity capabilities.
What are the different generations of Wi-Fi technology?
Wi-Fi technology has evolved through several generations, each designated by the IEEE 802.11 standard number. The original standard, 802.11, was introduced in 1997, providing limited speeds of up to 2 Mbps. Subsequent generations have introduced significant advancements: 802.11a and 802.11b in 1999 offered higher speeds and better reliability, followed by 802.11g in 2003, which combined the best features of both earlier standards.
The evolution continued with 802.11n in 2009, which introduced multiple-input and multiple-output (MIMO) technology for increased performance. More recent developments include 802.11ac, offering higher throughput and effective use of the 5 GHz band, and the latest 802.11ax (also known as Wi-Fi 6), which significantly enhances performance in crowded environments. Each new generation aims to meet the growing demand for faster and more reliable wireless connectivity.
When was Wi-Fi first developed and how has it changed over time?
Wi-Fi technology was first developed in the late 1990s, with the IEEE ratifying the first standard in 1997.
