🔹 How WiFi works:
The router receives data from an Internet Service Provider (ISP) over an Internet connection and then transmits it to your device via a wireless signal.
Devices (eg smartphones, laptops) receive this signal and exchange data, which is used to access the Internet.
Wireless signals transmit data via radio waves, typically at 2.4 GHz or 5 GHz frequencies.
Frequency band of Wi-Fi:
Wi-Fi generally operates in two types of frequency bands.
— -
🔹 2.4 gigahertz (GHz): This works well over a longer distance and can send signals well through walls or other obstacles. However, it is relatively slow.
5 gigahertz (GHz): This is capable of transmitting data at high speeds, but has a short range and cannot pass through walls very easily.
Advantages of Wi-Fi:
Wireless connectivity: WiFi allows you to access the internet wirelessly.
Mobile Connectivity: WiFi gives you an option to stay connected to the internet without mobile data.
Multiple device connection: Multiple devices can be connected simultaneously to the same Wi-Fi network.
WiFi Security:
There are some standards to protect the security of WiFi networks.
— -
🔹 WPA (Wi-Fi Protected Access): This is a Wi-Fi security protocol that encrypts network data.
WPA2 : Updated version of WPA, which is currently the most widely used.
Future WiFi Technology:
Wi-Fi 6 and Wi-Fi 7 are new generations of Wi-Fi technology, capable of providing faster and more efficient connections than previous versions.
