Some Common Questions that make Us confused.....Then all you need to know.... Q& A
How Router Antenna Works, Types of Antenna....

Q: My router is dual band. Now if I turn off the 5ghz frequency from the firmware, will the 5ghz antenna work at 2.4ghz?
Ans: Probably no router will be available now which does not have antenna defined for 2.4ghz or 5ghz frequency. Each router will have separate antennas for 2.4ghz and 5ghz.

Now the important thing for us is if I turn off the frequency of 5ghz then the antennas allocated for 5ghz will work at 2.4 GHz. The answer is 'no'.

Those of you who have seen the review of my D-Link DIR 819 router; They must know that there are separate chips for 2.4GHz and 5GHz and these chips are connected to two different antennas. Even in the review of TPLink Archer C24, you have seen how CPU, RAM plus 2.4 Ghz chip has been used together using Semiconductor Technology. But for 5 ghz, a different chipset was used, you see that.

So when you turn off the 5ghz chip, the attached antenna will also turn off. I hope you understand.

Q: Will I get more speed if I put the antenna back on the side of the house where I am?
Ans: There are mainly two types of antennas; Omnidirectional Antenna and Directional Antenna. Most of the Wireless Routers and Acces point have multiple antennas. These multiple antennas work to spread the frequency of the router evenly everywhere. These antennas are called Omnidirectional Antenna.

And there are some routers whose antennas will throw the frequency wherever you put it back. These are called Directional Antennas.

Now the question is whether the frequency will go higher wherever you turn the antenna. Well, it depends on the type of router you are returning the antenna to and what kind of antenna is attached to it.

If it is a directional router, then only the frequency will go in the direction you put the antenna back. And if the omnidirectional antenna is the router, then the calculation is different. How is the frequency of omni-directional router spread? Take a look at this router ................ place the antenna at 90 সাথে with your devices.


Q: If the speed of my line is not reduced, will the range be reduced or not?
Ans: Nah range will not decrease. Butt Effective Range will be reduced. This means that you are running a line of 10mbps bandwidth with a DualBand WiFi Router. So when you run WiFi from a very close router, you know the download speed, upload speed everything will be fine for sure. Because you will then run the mobile at 5ghz.

But whenever you move away from the router, the WiFi signal will continue to decrease, right? Also, the farther you go from the router, the higher the frequency interaption, especially for 2.4ghz.

When you go to test the speed, you will see that the download speed is decreasing, the upload speed is decreasing, and the ping / latency is also increasing. Why is this?

If you want to understand this, you must first understand how the mobile in your hand is communicating with your router. Basically your router will send the data to your mobile in the form of small packets. So the farther you are from the router, the more packets you will lose. What we call straight in Bengali is packet loss.

So whatever; Your mobile keeps calling the router again and again for the lost packet until the packet reaches it in full. So now you understand why the net is slow when you go away from the router? Then again there are different types of interfaces including walls, steel cupboards. That's why high mbps lines cause a little better end of WiFi Range than low mbps lines. And because of this low mbps, the range of the router may seem less to you. That's All. The higher bandwidth you take, the higher active frequency you can achieve.

There are also different routers that can't work well at the very end of the range. There are some routers that work very well up to the end of the range. It depends on the build quality of the router and antenna.
