The Birth of Wi-Fi and the Rise of 2.4 GHz
Wi-Fi, a term coined by the Wi-Fi Alliance, was first introduced in 1999 as a wireless networking technology that allowed devices to connect to the internet without the need for cables. The initial Wi-Fi standard, IEEE 802.11b, operated on a frequency band of 2.4 GHz, which was chosen due to its ability to penetrate solid objects and provide a decent range.
The 2.4 GHz frequency band was already occupied by various devices such as cordless phones, microwaves, and Bluetooth devices. However, the Wi-Fi Alliance implemented measures to ensure coexistence with these devices, making it possible for Wi-Fi to thrive in this frequency band.
How the 2.4 GHz Network Works
The 2.4 GHz network uses a type of radio wave to transmit data between devices. Here’s a simplified explanation of how it works:
- A Wi-Fi router or access point (AP) is connected to a device that provides internet access, such as a modem.
- The router or AP broadcasts a unique identifier, known as an SSID (Network Name), which allows devices to detect and connect to the network.
- When a device, such as a laptop or smartphone, detects the SSID, it sends a request to connect to the network.
- The router or AP authenticates the device using a password or other security measures.
- Once authenticated, the device is assigned an IP address, allowing it to access the internet and communicate with other devices on the network.
