It is absolutely fascinating to learn more about the devices we use on a daily basis, I wasn't expecting to be having this much fun so far lol

[MatteoR]

What I find to be more impressive than the countless informative and well structured videos professor messer creates, is the fact he never seems to make a mistake when explaining anything, the fluidity of his communication is insane lol

[starmartyr]

This and the prior videos - besides being a great study tool for A+ certification - were a wonderful summary of the stunning progress we've made with technology throughout the past 30+ years. It's like a walk down memory lane for this 40 year old who has been online since ~1995, and has been using computers since cassette tapes were a storage medium, lol. Thank you Prof. Messer, especially for putting these all up free of charge! When it comes time to purchase study guides and practice tests, you have my business.

And I can't wait to view all the rest of the videos!!

I have encountered lots of educational videos for this course but so far, your voice doesn't make me want to fall asleep lol. Thank you! It's very informative and detailed. I'm just starting to change careers so I'll take your videos to heart. Kudos!

[michaelsouza]

Thank you for posting these videos! Taking my exam next week and they are a great supplement to my course work!!!

[ThichabodCrane]

Watched the earlier videos in this playlist and should have commented earlier. These are extremely helpful. Thank you so much!

Trying to map out the development of the GSM and CDMA standards throughout the years is so complicated because of all the nomenclature. But this is good for some basic ideas.

[NATESOR]

The real reason they call them cell phones is because we are prisoners to our phones... I'll see myself out.

[Sanjaykumar-bdds]

Absolutely amazing playlist for Comptia A+ certification. Thankyou professor messer. I have a question that I want to order your core 1 and core 2 physical addition books, can you or someone who already purchased the books tell me like what content is written in books like are there practice questions in the book or just topics? Thankyou

6:28 would another example of this be wireless calling?

[jeremiahempringham]

what items are iot that are using mobile internet i find most things are using the home wifi which is isp and not mobile. anyone educate me on that?

[jonmagnam]

This reminds, growing up I thought LTE was the light version of 4G. 😂

[michellenicole]

For CDMA did the user have to put in a code to speak to that person?

[religinjrclips]

If I buy his course notes for core 1 and exams bundle. Is that all I need for the core 1 exam for A+. And ofc watching all of his course videos like these?

[sapphireryan-campbell]

are there any websites that offer completely free study labs? online no free trials.
