What's That Infrastructure? (Ep. 5 - Wireless Telecommunications)

John Maloney has Siri and other tracking stocks agreed 👍

Remember rabbit cell phones?

🗨️😽

Permission to use some clip in this video for school purposes thank you

Wow the greatest weapon in history😮

No visible coax running up to those yellow features on the structures in Quebec. Likely not cellular (yet).

Unbelievably short video. Hardly what I would call informative. Why make a video less you're going to be thorough about it? Other videos on this channel or a lot more in depth. Disappointed.

This 'infrastructure' series is truly international, with pictures from all around the world. I was impressed that you obviously made an effort to pronounce the names correctly. Now all you have to do is completely rid your videos of SAE units.

Sept 16, 2022 This is Irene Imanil (real, King Philip, II) calling from Waikiki Public Library @ 1340 hour to tell you to turn off mobile/cell phone usage and go back in time to land line. Keep satisfied with internet and world wide web service, not mobile/cell phone. That mobile/cell phone usage has become criminal through tracking, shadowing, instructions. Crime rates could increase. That breached gridline could enable even little guys to wiretap for wrong purpose, so one has to end usage of mobile/cell phone.

I live in a small village in Poland and have 36mbit up/down (limited by ISP) via WISP/WiFi and around 50mbit when using LTE. Its crazy when I compare it to the beginnings of mobile internet via GPRS.. (both with unlimited data and at a cost of around 20eur/month each)

Small cells is what 5G is going to be based on. Instead of having antennas on tower sites, due to the extremely high frequency of the mm wave (60 GHz), more smaller cells are required to have coverage. This is because the 60 GHz radio waves don't really bend or refract around objects, therefore if the smallest of things is in your way, your signal may decrease in upwards of 30-40 dB, in some cases making it unusable. The high bandwidth of these 60GHz signals require there to be more of a signal present in order to take advantage of all that bandwidth. These signals don't use conventional AM or FM modulation, either. These use a modulation called OFDM (Orthogonal Division Frequency Multiplexing). This is not your conventional CDMA or GSM. This operates differently, applying the same technologies that CDMA and GSM use just a much larger scale. There are plenty of resources explaining how OFDM works, so I won't get into it here because it's a pretty complex topic, but it allows much more data to be transferred than other methods. So basically instead of having 300 foot towers every couple of miles, you're going to have these small cells roughly every couple hundred feet. Also, these small cells aren't just used for 5G, they can act as small base station sites to fill in areas of poor coverage for existing technologies like 4G LTE. In hilly or mountainous terrain, it is really a challenge to get coverage into valleys. So, this new technology of small cells can help fill in the gap of coverage into these hard to reach areas.

I design this infrastructure for a company called CSAi and I honestly didn’t know some of the stuff in this video

Shoutout to AT&T Long Lines

"Thanks for spening your hard earned megabytes on this video..." is a depressing statement.

TeleCom companies have been given massive subsidies in North America and have pocketed that money and saddled Canadians with exorbitant rates for mobile data. $71/mo for 1 Gigabyte is price gouging.

You barley scratched the surface, message me if you want more information on telecommunication.

LOL, I am not the least bit surprised that Long Lines was the #2 reference.

I suspect that those yellow rectangles, and the uprights they're attached to, are part of some signaling system related to that bridge.

Been watching your channel for awhile, just started a job as a tower technician a couple months ago and brought me to this old video. Keep up the good work Grady! ❤️

I worked for Western Electric in the early 70s and the microwave SOLID copper microwave tubing was very visible inside the telephone buildings. I can imagine that tubing is long gone, probably into someone's garage...

Thank you for making this series, it's been fascinating.

Do you still do these? And if so what do you want pictures of, I'm an electrician and have worked on everything from 250 meter wave tanks, weather radars, cellular towers, sewage pump stations and a whole host of others

We could use a video on 5G, speaking of which. Benefits, dangers, perhaps your insights on some of conspiracy theories surrounding 5G. What say you Grady?

I can tell you’re an engineer because you made a TLA out of this series in only 5 videos :-)

No VSAT coverage?

Literally got an ad about fearing/blocking 5G on this vid like wtf

Yellow box things are Wave guide horns if I'm not mistaken

The old AT&T long lines microwave towers from the 50's-60's make great infrastructure tourism. They were spaced about 30 miles apart and used to carry a lot of telephone calls and video. They've been replaced by fiber optics, but some are still in service as cell towers or simply abandoned. With the cost of spectrum increasing, I would imagine that fiber optics are far cheaper per bit transferred, even with the increased cost of burying fiber everywhere.

In the UK (at least), you often see mobile phone antennas on large electricity pylons, I was told this helps carry the signal further? Not sure.

I know its been quite a while but I just came across this series and instantly recognized that AT&T antenna array as being just down the street from my hometown! Extremely strange to see it featured here! A bit of further context: it's the AT&T building in Bloomington, Indiana. (Home of Indiana University) Parts of it are boarded up but it seems to still be operating as an AT&T data center after all these years,, they certainly still own the building, there are a couple modern AT&T logos about. The antenna stand was built in 1970.

He is one in a million, best among many, most trusted , I almost gave up on trading then I met him through a friend, Austin is the most trusted trading expert who helped the life of my family and I ,.

Any Chance of this series coming back?

Got a giant flagpole that hides several cellular antennas in the area. Seen it open once. I’ll snap a photo if I see it open again!

I seen cell phone tower in Las Vegas on Northside looked like robotic palm tree

Hi from Somalia...........enjoyed

I really hate in the US we have individual cell networks. We would get an overall better product if all the spectrum was used universally. Having choice and redundancy is nice, but it just doesn't make sense for infrastructure services. Imagine having sewer companies complete with their own networks.

Cathode /Anode Or Magnetic Bell Used For Logistical Systems.

I love learning from your videos

I want a report on this topic .. I hope someone who has a report sends it to the email in the responses .. Thank you

Hey Grady! Love the channel, and came back to this one hoping to learn about a little more about the wireless technology utilized in cell phones in addition to learning about the infrastructure which makes it all possible. I know it's not really civic engineering but I think a lot of people would be really interested to learn! There's so many different boxes and antennas on those towers, the mystery is killing me.

Are you going to make more of these videos?

Antennas? Surely Antennae old chap.

my area used to be only served by microwave and let me tell you it's terrible. it's better than living in the dark ages, sure, but you know what ruins the signal? TREES! they charged us like over 100 dollars a month for less than 1 mb most the time and told us well you know, it's all the water in the tree leaves, what do you want us to do about it? honestly satelite internet (which we switched to for almost a year) was faster. they ran a fiber cable in front of our house though so now we pay the same amount for literally like 100x the internet speeds. microwave is 80% just scamming people out of their money.

"Thank you for spending your hard earned megabytes to support this channel"

Damn you dont need to make me cry man, you channel's awesome!

You will all burn in hell, for your work in the 5G roll out. Believe it.
