Introduction to Wi-Fi Technology
Wi-Fi technology has become an integral part of our daily lives, revolutionizing how we connect to the internet and share information. This wireless networking technology has transformed the way we work, communicate, and access digital content, making it possible to stay connected virtually anywhere.
How Wi-Fi Works
Wi-Fi operates using radio waves to transmit data between devices and wireless access points. These radio signals typically operate in two main frequency bands:
- 2.4 GHz – Offers better range but slower speeds
- 5 GHz – Provides faster speeds but shorter range
When devices communicate over Wi-Fi, they convert digital data into radio signals and back again, enabling seamless wireless communication.
