Well Done! Thank you!

Thank you

Hey telecomtraining I have an issue I’ve been dealing with for years now and I’m truly at my wits end and don’t know what to do so long story short I live in an apt building and when I go to play a game online the games feel sluggish and unpleasant on the eyes but it’s not lag and when I disconnect from the internet completely my games feel smooth and snappy , if ther is any guidance or help you can point me in the right direction I use dsl and isp always says everything is fine on their end, can this be some sort of interference happening causing like missing info and like a jitter if you will almost as if all my inputs aren’t being registered ?

Cool!!!!!!!!!

Those two frequencies are used only for full duplex. 4G & 5G are moving to half duplex, which uses the same frequency for both directions. In fact, I'm not aware of 5G using full duplex. Also, where are you getting 10 sq miles from? The range of a cell site is dependent on it's height and the trend is to have more sites, with lower antennas, particularly on the higher frequency bands.

You mentioned 2 different frequencies for the handset to transmit and receive on. This is only true with full duplex. With 4G & 5G, half duplex is also often used. The advantage of HD is the ratio of up and down stream traffic can be variable, whereas with full duplex it's the same.

Great, informative videos! Very educational. THANK YOU! ❤ I can’t seem to find the videos for the 2G, 3G and 4G evolutions though. Could you please share the link? Appreciate it.

great job; thank you a lot

AMPS was never on 1900. It was on 850 MHz only.

Hi. Great video with clear explanations. My question is how does the cell tower know which phone another phone is trying to get connected to during a call.

I recently switched to cable from DSL. The download speed is 4x faster than DSL. It could be that more bandwidth is available on the cable line because fibre optic was installed throughout the neighborhood last year, so customers are switching from cable to fibre optic. For the DSL line, my download speed matched the results of the Ookla Speed Test, which was 24 to 25 Mbps. For the Coaxial line, however, there is a difference between the speed test result (about 950Mbps) and the rate I actually get when I download files, which is about 100Mbps.

Very good information, thanks

This is almost correct but not. You will not be pumping 100mbps at one end to get 50 mbps out the other. The lines will only be capable of 25 mbps because that's the maximum they could negotiate at that distance. They aren't "losing" the data per say.

Great explanation, thank you for making this video!

How do terminate a 25 pair to a patch panel

Nice video! Thank you for making this one. It's very helpful.

incredible, thanks for going out and doing this extra research I wouldn't have thought to do really helped my understanding of the differences

thanks. I'm doing disaster research and this is helpful

Your Tip and Ring colors Violate and Slate are reversed!!!!! TIP IS VIOLET RING IS SLATE

thanks, this was really helpful

So did I understand correctly? While the cable infrastructure is saturated during peak hours, will DSL be less saturated under the same conditions?

Who will provide airtel telecommunications towers

Great Presentation Trevor

❤😂🎉🎉😢😮😅

Thank you! I'm currently taking a Network + class and this was a great explanation!

In this video. You have the red/green pair as red=tip, green = ring. Isn't that reversed?

Great thanks, Now I know how to access my system when I'm talking to my provider about my speed.

you have violet and slate intrer changed ! violet is a tip color not slate

only thing i'll add is that when i lerned the circle diagram we started where 3 is on a clock, cus if u plop the sirxle diagram next to a graph, the y axis for both graphs line up

The IMSI has 3 digits country code (USA is not 1 but 310), 2 or 3 digits of network code, and the rest is the mobile subscription identification number (MSIN). Takes a 1 second google search...

The further the signal goes the more DNA damage, impairment of antioxidants, decreased glutathione concentration catalase, superoxide dismutase, increase in lipid peroxidation will occur in all humans, All proven by non industry independent research and published on the Enviromental Health Trust website. Who will you beleive? An industry that can't get insurance against biological damage to all life forms , or independent research of highly skilled scientists and doctors.

THOSE ARE COLLINEAR SNTENNAS, CORPORATE FEED STRUCTURE. AMPS SERVICE USED TO USE VOLLINEARS, WITH ONE INVERTED FOR NEAR FIELD COVERAGE THAT THE OTHER ANTENNAS WOUKD ',OVERSHOOT' WITH THEIR RF SIGNALS. PANEL ANTENNAS ARR ACTUALLY SMALL YAGIS, AMD NOW, THEY ARR ELECTRICALLY MANIPULATED FOR DOWNTILT. 45 YEARS RF ENGINEERING IN CELLULAR AND TRUNKED/ANALOG/DIGITAL RADIO SYSTEMS.

Thanks a bunch for taking your time to make this educational video. I've always been drawn to telecommunications and mobile networks in general. Currently I'm working as a network engineer with a specialization on WiFi. I've heard that cellular networks are a lot more complex than WLAN. Do you think pursuing a master's degree in telecommunications would allow me to transition into the cellular side of networking?

What would it take to start a go fund me and buy a tower and make cell service free for the whole city? How much money would that take?

So the bonding happens on premise right? Where do I get these bonding routers? Would I be able to bond 2 separate VDSL lines (each with their own router/modem) into 1?

Why I am always late to such a awesome video. I am landed here after watching your part 1. Thank you so much for the explanation. As a sysadmin for a ISP and DTH I was always curious about telcos network. And today I found you. Much love from Nepal 🇳🇵

Finally!!!! Someone, who has explain Feq in simple terms!! Now! After 1yr, I understand Feqs!! Thknu!!

If a call connects to a tower in the next city, will it transmit to a new tower closer to the customer as it becomes available? Is it safe to say that you can accurately place where someone is based on their phone pings?

Can someone who worked on my macbook be connected thru this and I not know??

So that's how the shut ur number off if u don't pay it

Finally, a guy who knows what he's talking about and isn't just reading a Wikipedia article with an Indian accent.

What a high quality video!. I have a question: Does the base station constantly maintain communication with my phone once it's powered on, even when I'm not actively using it for a call, so it can immediately update my location as soon as I move?

If you are on dsl with fiber . No problem

Been using this video as a reference for about 2 years now for pbond bells training was horrible this video I’ve actually learnt things I can use in the field thanks a bunch!

best video on the topic ... thanks brother
