It really starts at 4:11, just skip and save yourself 4 minutes. and set speed to 1.5.
Think you bro ¶
Exactly what i did.
Nice
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 ❤
Save yourself some time, jump to 4:20. Brilliant overview.
Tom- one of the best videos presented by cwnp.Really gives a clear understanding of all the basics.
How the heck can 19 people give this a thumbs down?????? Tom & CWNP are the best out there at explaining this stuff.
Joel Panetta Online Simple why there are 19 thumbs down. 19 idiots = 19 thumbs down.
Keep in mind there are people that actually believe that earth is flat. unfortunately, they have access to the internet too.
Wikipedia is better. Or a text book, MIT lecture for that matter.
Research cellphone radiation
Research cellphone tower radiation
Research wireless/wifi radiation
How narrow minded you people must be to believe there are no downsides to wireless tech........... pffff tbh gtfo fried zombie brains and your wireless tech
Good video! Some of the discussion reminds me of EE courses taken long ago.
Great refresher. Thank you.
Great video Tom.
Thank you for this video, really informative
Good Info. Thanks for the video!
Great Video explaining fundamentals
Very informative, thank you for sharing
Thank you. Good video!
Thank you, it was really informative.
Brilliant outstanding.
very good video to start learning about wireless technologies basics
Thank you Sir!!
Where can I get complete video training from this guy please ? So well explained
I hear you 🤚🏾
thank you
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.
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???
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.
props... someone knowing their stuff. most ppl if you said 80m or 10m etc they wouldnt even have a clue.
I know all of these things. Thank you
then why the heck are you here? sshooo!! get the hell out!
thanks a lot
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.
this good video
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). ]
What unique concerns must be addressed by the designer of a WLAN network?
These are great, but if you add animation when explaining some of the concepts like interference etc. these videos would really take off
thanks

In a 4x3 AP, Is there a way to setup the client to connect not using 3x3 but 2x2 or 1x1 ?
Remember that when you watch this now, there is UNII-4 Channels aswell! (75 MHz additional!)
yup

Hello, what is controlling power output of the access point? Voltage or amperage? What increases or decreases the transmission power?
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
Excellent explanation sir
But how to change 11 and 12 dbm in mw by your 3 and 10 technique
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.
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
Trainning's voice sound like from Kevin Wallace , right?
What about Omnipeek in analysis of network?

If anyone reads this can they please direct me to radio frequency training for tower climbers I'm trying to find a review course online while I'm waiting for my own industry to provide me with the class for some reason I cannot find anything online
Where are you rushing like that? Any consideration for listeners?

Brah, I have known this for years and they made a certificate for it??? What!?
what is rf duty cycle and how is it different from PWM duty cycle
hey
I can hear 6ou
sorry...
can you make subtitle in indonesian language in this video?
@@cupcupcup1802 wkwk i didn't need it again
too fast for beginners
Can you honestly say that these bands are innocuous and pose no harm to human life?
Hello is 80 and 160 recommended today for 5ghz
No
For home use you could get away with 80. For a business I would stick with 20, or if it's low density 40.
