It really starts at 4:11, just skip and save yourself 4 minutes. and set speed to 1.5.

thanks to this video, i was able to succefully pass the past exam questions i’ve been practicing. I got he past questions from Leanology World for free , they gave me official CWNA 109 study guides for free as well but those study guides where not enough for me, this video tutorial was able to put the knowledge that i got from the study guide into perspective. ❤ thank you a much for making this tutorial video ❤

@NassimDhaher7 років тому
at 28:00 you say:"Interference happens at the receiver", but won't the sender receive the responses from the "receiver" as well and therefore become a receiver. Or you meant to say interference happens on reception of signal???
@thepokergrind7 років тому
7:43 : wavelength is a distance expressed in meters, and the period is in seconds (how many cycles in a seconds = n hertz). They seem mixed up in their definitions.

When it comes to refraction: Generally how wide is a wave length ? You mentioned a filing cabinet 🗄️ while the display gives an example of a roof top ? Also what is the size difference between that of say 2.4 opposed to the 5ghz [ if you aren’t sure of exact dimension- Maybe you’d be able to say which is wider over the other (2.4 or 5). ]

In a 4x3 AP, Is there a way to setup the client to connect not using 3x3 but 2x2 or 1x1 ?
@Hazwan-ud7mz4 роки тому

@ruchitaahluwalia96956 років тому
It would have helped if you've used similar graph to 2.4GHz to describe the 5GHz so novice person like me can visualize the difference in comparison of two. Other than that it was a great video.
@kworgz6 місяців тому
These are great, but if you add animation when explaining some of the concepts like interference etc. these videos would really take off
@jeffm27873 роки тому
2.4 is alive and kicking, well at least for home and IOT related devices. Once you get out of the cities it becomes completely useable even for 4k streaming, etc. Use 5Ghz of course where possible.

@akhileshkumar-fu6of6 років тому
Excellent explanation sir But how to change 11 and 12 dbm in mw by your 3 and 10 technique
@JonathanWaltersDrDub6 років тому
The premise for that quick chart is that 10^(0.3) = 2 approxmiately. For increasing 1 dBm we would see that 10^(0.1)=1.25 so we would multiply the original power by 1.25 to increase its strength.
@georgecuclea77704 роки тому
11dBm = 20dBm-3dBm-3dBm-3dBm 11dBm= 100mW/(2*2*2)=100mW/8=12.5mW and 12dBm= 3dBm+3dBm+3dBm+3dBm 12dBm=2mW*2mW*2mW*2mW=16mW

@spiderx012 роки тому
Hello, what is controlling power output of the access point? Voltage or amperage? What increases or decreases the transmission power?
@CinncinnatusРік тому
wattage.... ie was both... typically voltage is a fixed point due to hardware limitations (now...) so its mainly amperage but it very well can be both. but since almost no-one deals with HV amplifiers now its pretty much always amps now but you really dont even deal with that due to frequency based modulation not amplitude. and if we talking your home wifi set it to the lowest possible setting that still lets you get a signal without issues. eg. my home 2.4/5ghz wifi runs @ 1/4 watt vs the default of 1 watt
