How does Wi-Fi technology work?
Wi-Fi technology works by transmitting data over radio waves between devices. Wi-Fi networks use a type of radio wave called a microwave, which has a high frequency and can transmit data at high speeds. When a device, such as a laptop or smartphone, connects to a Wi-Fi network, it sends a request to the network’s router, which is a device that manages the network and connects it to the internet. The router then transmits the data to the device over the radio waves, using a protocol called packet switching.
The packet switching protocol breaks down the data into small packets and transmits them over the radio waves. The packets are received by the device and reassembled into the original data. Wi-Fi networks use a variety of techniques to ensure reliable data transmission, including error correction and encryption. The data transmission rates of Wi-Fi networks can vary depending on the standard being used, but they are typically much faster than traditional wired networks. For example, Wi-Fi 6 networks can transmit data at speeds of up to 9.6 Gbps, making them ideal for applications such as online gaming and video streaming.
What are the different types of Wi-Fi standards?
There are several different types of Wi-Fi standards, each with its own set of features and capabilities. The most common Wi-Fi standards are 802.11b, 802.11g, 802.11n, 802.11ac, and 802.11ax. Each standard has a different data transmission rate and range, and they are not always compatible with each other. For example, devices that use the 802.11b standard can only connect to networks that use the same standard, while devices that use the 802.11n standard can connect to networks that use the 802.11b, 802.11g, or 802.11n standards.
The different Wi-Fi standards also have different security features and capabilities. For example, the 802.11i standard adds support for advanced security protocols such as WPA2, which provides strong encryption and authentication for Wi-Fi networks. The 802.11ac standard adds support for beamforming, which allows routers to focus their signal on specific devices, improving the range and reliability of the network. The latest 802.11ax standard adds support for orthogonal frequency-division multiple access (OFDMA), which allows multiple devices to share the same channel, improving the overall performance and capacity of the network.
What is the difference between Wi-Fi and IEEE 802.11?
