What is the purpose of a VPN in a wireless network?

The purpose of a VPN (Virtual Private Network) in a wireless network is to create a secure and encrypted connection over the internet. This ensures that any data transmitted between a user’s device and the VPN server is protected from eavesdropping or interception by unauthorized parties. By encrypting data, a VPN provides privacy and security, especially important when using public Wi-Fi networks, where the risk of potential data theft is higher.

In addition to securing communications, a VPN can also allow users to access resources on a private network from a remote location, thereby enhancing flexibility and security for remote workers or travelers. This functionality is crucial in today's digital landscape, where sensitive information is often transmitted over potentially insecure channels.
