What is Wi-Fi and how does it work?
Wi-Fi is a type of wireless networking technology that allows devices to connect to the internet or communicate with each other without the use of cables or wires. It works by transmitting data through radio waves at a specific frequency, typically in the 2.4 gigahertz or 5 gigahertz range. When a device, such as a laptop or smartphone, is connected to a Wi-Fi network, it sends and receives data to and from a wireless router, which is connected to a physical internet connection.
The data is then transmitted back and forth between the device and the router, allowing the user to access the internet or communicate with other devices on the network. Wi-Fi networks use a variety of protocols and technologies, such as IEEE 802.11, to manage the transmission and reception of data, ensuring that data is sent efficiently and securely.
How does Wi-Fi track and collect data about me?
Wi-Fi networks can collect data about you in several ways. One way is through the device’s MAC (Media Access Control) address, which is a unique identifier assigned to each device’s network interface. When a device connects to a Wi-Fi network, the router logs the device’s MAC address, allowing the network administrator to track the device’s activity and location. Wi-Fi networks can also collect data about the websites you visit, the apps you use, and the files you download or upload.
Additionally, many public Wi-Fi networks, such as those found in coffee shops or airports, may require you to log in with your email address or social media credentials, which can provide them with personal information. Some networks may also use data analytics software to collect data about your browsing habits and behavior, which can be used for targeted advertising or other purposes.
