One thing you need to do ( to improve your WiFi coverage )

If you ever wondered where to place your wi-fi router, to have good coverage but also increase your speed. then this article is for you

You can use one access point, but 2 are preferred for roaming purposes. both should have the same SSID ( wi-fi network Name )

The very first thing that needs to be done is a site survey

Site survey for dummies

So let’s learn how to perform a manual site survey, no special hardware needed, only your Mac and wi-fi router. a good site survey will promise you that signals that spread in the air will have the best chance to hit your home appliances, with minimum loss

Let’s start

-65d dBm is a quite balanced signal quality measurement, which will be suitable for most apps, either web browsing and video streaming ( assuming that you have the bandwidth for it, signal quality, determines only the quality of the signal, yet if you are limited with bandwidth as in the case where your other members in the family consume lots of data, then you have another problem )

The manual process is as follows:

Now take into concern that there are 2 types of ways to measure a signal:

The passive way and the active way

That is quite OK for a survey, but professionals usually prefer to make an active site survey where they interactively moving data as they listen to the signal

Keep moving and get to the place where your wi-fi analyzer app says -65dBm

A side note, the signal measure also known as RSSI (received signal strength indicator ) is a measure that you see in your smartphone and on your laptop whenever you connect to a wifi network, It’s the received power, the signal amplitude as our wireless card circuitry senses it.

Your wireless router broadcast signals at a power level, usually 20dBm, which is 100mw, if you walk one meter from it, the signal will decrease following physical phenomena such as free space path loss and the inverse square law ( but that is for another article )

Once you found the -65dBm signal measure, you have now found your wireless router placement, signals are bi-directional, so now you know that you can place your wireless router, at the -65 dBm location and just for a final check, go back to the beginning of the office with your phone and check to see that you are on -65dBm

The next thing to do, is actually walking around with your wi-fi app, and click around every few meters, and guess what, you’re actually sampling the signal, to see the perimeter where -65dBm is still valid.

where it reaches -70dBm, you know that this is the end of your AP signal

Then we do that again, and now from the opposite side of the office

It is good to have a 10 dB minimum overlap

Your Mac, will soon, seek to roam to the second AP, but that is another video

Now remember, this is just a coverage model, you should also take into concern Density
