Wi-Fi stands for wireless fidelity uses two frequency bands available to use when setting up Wi-Fi network.
- 2.4 GHz
- 5 GHz
So now let us talk about where and which types of frequency most widely used in daily life.
In general 2.4 GHz is the most universally used frequency. 2.4 GHz is the most compatible with standard for building a wireless network known as 802.11b and 802.11g.
This frequency most common one, because it can result in device interfering with each other.
5 GHz is less common, It is range about 30 meters. Result is not good too much compare to 2.4 GHz. But sometimes it achieve high speed reason of less crowded frequency.
5 GHz is the most compatible with standard for building a wireless network known as 802.11a and 802.11n.
Now let us check it out some advantages and disadvantages of 2.4 GHz frequency and 5 GHz frequency :
2.4 GHz :
Advantages :
- Accessible from greater distance
- Compatible with lots of devices
Disadvantages :
- Crowded frequency from all the device that supports
5 GHz :
Advantages :
- Lots more bandwidth
- Generally less interference on 5 GHz because the frequency is not as crowded
Disadvantages :
- Available for shorter distances
- Not compatible with as many devices
