Definition: 4G stands for the fourth generation of wireless mobile communication technology. It succeeded 3G and is designed to provide faster data transfer rates and more reliable communication.
Technical Details:
Data Rates: 4G offers significantly higher data transfer rates compared to its predecessor, 3G. It can provide peak download speeds of up to 1 Gbps (Gigabit per second) and upload speeds of up to 100 Mbps (Megabits per second).
Technology: 4G uses various technologies, including LTE (Long-Term Evolution) and WiMAX (Worldwide Interoperability for Microwave Access), to achieve high-speed wireless communication.
Frequency Bands: 4G operates on a range of frequency bands, including the 700 MHz, 800 MHz, 1.8 GHz, 2.1 GHz, and 2.6 GHz bands, among others.
5GHz:
Definition: 5GHz refers to the frequency band used for wireless communication in the 5 GHz range.
Technical Details:
Frequency Range: The 5GHz band spans from 5.150 GHz to 5.850 GHz and is commonly used for Wi-Fi communication.
Advantages: The 5GHz band provides advantages like reduced interference, as it is less crowded than the 2.4GHz band, and it allows for higher data transfer rates.
Wi-Fi Standards: Wi-Fi standards that operate in the 5GHz band include 802.11a, 802.11n, 802.11ac, and 802.11ax (Wi-Fi 6).
Channels: The 5GHz band is divided into multiple channels, each with a certain frequency range. Channels in this band do not overlap as much as those in the 2.4GHz band, reducing interference.
