This guy is such a good teacher. Also follows the objectives to a tee which makes it easy to focus in on certain subjects if you need to retake a test. Thank you for this series!
Every video you make is simple and easy to understand. Before every video, I'm thinking I won't be able to understand it but after watching it, I actually do. Thank you Professor!
Hi professor, I noticed that you mentioned the Zigbee connections were on a meshed, open network. You also mentioned that the Z-Wave network is meshed but I was wondering if it was a closed network (since it is proprietary) or is it also an open network like Zigbee? Thank you so much.
Hi, can you please explain what it means by an open standard with two major wireless standards associated with Internet of Things technologies, does an open standard mean that is NOT a proprietary system?
You need to know the differences between the two frequency ranges and the ranges used by the different wireless standards. You don’t need to know specific frequencies or channels.
@@professormesser thank you because i was really stressing with the amount of information in this video, just trying to figure out how to take it all in lol
I've watched all of these videos twice and even though I thoroughly understand the content I'm having a hard time remembering the vast amount of information. Any tips?

You have done a great job Professor

The radio-frequency section was such an eye-opener. I always wondered how those things worked...
legend, thanks for the training course!
Hi Prof. Messer! On the background of 802.11 technologies text, I see a banner photo, is it Turkey?
Yes, it is!
Thank you so much for your knowledge. I leaned so much.

So thankful for this 🙏🏾🙏🏾🙏🏾

How come on my modem/router for 5ghz I only have the option for channels 36-48 and 149-161. Based on your video I should also have channels 100 -149.
It sounds like you might have an older wireless device that does not include the newer frequency ranges.
@@professormesser Thank you for responding Professor. That makes sense now. I bought my modem/router in 2014.
Do I need to know the specific channels for the 5ghz band? For the exam?
You need to know the differences between the two frequency ranges and the ranges used by the different wireless standards. You don’t need to know specific frequencies or channels.
@@professormesser thanks, I also wanted to know if a USB receiver (for a mouse or keyboard) was an example of zigbee or bluetooth? Or both?

no disrespect or anything, your videos are working great for me. sometimes i'm just not sure what i need to retain and what i don't
@@QuanLovesGaming bluetooth
What channels do we use for 5 GHZ
I would assume the range is 5150Mhz to 5925Mhz, broken into IEEE channels, 36-64 100-165 @20Mhz, 36-64 100-161 @40/80Mhz and 36-64 100-128 @160Mhz
I use 5ghz and I noticed my net seems faster is the true or am I crazy my isp is telling me that it is the same as 2.4ghz
5ghz greater speed. 2.4ghz greater reach
@@markschultz1476 thought so thank you

I am studying the CompTIA study guide and watch the videos. Just watching the videos is not enough
Make flash cards on quizlet!
@E115 where to get those tests ? please

I swear i seen the RFID in the first matrix movie it's all making sense lol
