What is a wireless network?

A wireless network is a system that allows devices to connect and communicate without the use of physical cables or wires. Instead, it relies on radio frequency signals to transmit data between devices such as computers, smartphones, tablets, and other electronic equipment. These networks facilitate the sharing of resources, internet access, and data transfer within homes, businesses, and public spaces.

Wireless networks are commonly implemented through technologies such as Wi-Fi, which provides high-speed internet connectivity within a limited area, or cellular networks that enable mobile communication over larger regions. They offer the advantage of mobility and convenience, allowing users to access information and services from virtually anywhere within the network’s coverage area.

The setup of a wireless network typically involves a central device called a router or access point that broadcasts signals to connected devices. Security measures such as encryption protocols are employed to protect data integrity and prevent unauthorized access. Overall, wireless networks have become integral to modern communication infrastructure, supporting both personal and professional activities with flexibility and ease.
