Dual Band Wireless Routers have the capability to transmit on the 5GHz and 2.4GHz wireless band. What is the difference between 2.4GHz and 5Ghz? Which is better, the 2.4GHz or the 5Ghz? The major difference between 2.4GHz & 5GHz is the range and the bandwidth. 2.4GHz frequency can reach farther than the 5GHz frequency. So if your requirement is coverage rather than bandwidth, you should select 2.4GHz rather than 5GHz. Higher the frequency the attenuation of waves will be more.
2.4GHz encounters more interference compared to the 5GHz signal, reasons being, Most of the wireless devices run on 2.4 GHz starting from cordless phones, Microwaves, Bluetooth, amateur radio & Television, etc. Only 3 non-overlapping channels (channel 1, 6, & 11) compared to 23 in 5GHz which isolates the 5 GHZ from other signals around. Overall the 5GHz has shorter range compared to the 2.4GHz. It is recommended to select the 2.4 GHz if you using computers and wireless devices to access the Internet for simple browsing and email. These applications do not take too much bandwidth and work fine at a greater distance. However, if you are in a place which is crowded with more wireless signals, it is advisable to use the 5GHz network to avoid interferences. Furthermore, the 5GHz is most suited for devices which require uninterrupted wider bandwidth for video/audio streaming or multimedia content.
