Difference Between Single-bands And Dual-band Routers


It is the things we take for granted that hurt us the most. When it comes to internet connection using Wi-Fi, it is common to find routers in many homes and offices. However, we tend to ignore the importance of what types of routers we have. Well, I got this one from my ISP provider, sentiments shared by most people. Consequently, due to the number of devices and work, we end up with poor internet connection. To choose a router, you have to understand some of the basics about routers.

Right, it is all about how fast your internet connection is. Routers play a vital role. The Wi-Fi standard often called 802.11 with either a, b, g, n or AC to show its different versions. Also, the versions are backward compatible. However, g speeds are much lower compared to the n version. AC version is the latest and considering market prices you should consider purchasing one.


Wireless communication takes place via frequency bands. For all versions leading up to 802.11g used frequency of 2.4GHz.Afterward, in the n and AC versions support both the 2.4GHz and 5GHz frequency bands. There are several drawbacks to using the 2.4GHz frequency band. They are;

1. The presence of transmission channels that only are three and overlapping, therefore, allowing for disturbance of connection by electronic devices.

2. 2.4GHz frequency band limited the speed of internet connection due to its narrow band.

These problems can be corrected by just changing your router to a dual-band one. It has the following advantages;

1. Special Wi-Fi networks for video and gaming that improve the user experience.

2. Ability to change over the 2.4GHz and 5GHz frequency bands as well as using them simultaneously.

3. It is relatively affordable due to increased availability in markets.

Despite all the advantages of dual-band routers, it possesses some disadvantage. The operating range may reduce due to hindrances. This is due to the fact that higher frequencies lose their power when going through obstacles. However, you can remedy this problem. Using AC specifications, there is a feature called beamforming. What it does is that it helps in transmitting signals about where the devices are located.

Also, dual-bands can be categorized into two, selectable and simultaneous dual-band. The selectable dual-band allows you to select between the 2.4 or 5 GHz frequencies. Simultaneous dual-band allows you to choose both frequency bands at the same time.


It is clear that dual-band routers are way better than the single-band routers. However, it all depends on the needs of the user. In spite of the needs of the user, one should always remember that it is important to move with emerging trends.
