Spectrum so called "Air-Waves". Transmitter/receiver in your phone along with your antenna is designed to read/convert/modulate/digitize the Air-waves signal. Each wave length carries analog signal which will be translated to 0 and 1 (digital). Why? Person in California calls his gf "Hey; how you doing" who in Miami. Hey;how you doing is converted into a digital code which will be further converted into an analog code (radio-wave) to be transmitted to the nearest cell-phone tower. Through cell phone tower, it will going to the nearest exchange/this Verizon building for example. Before that digital code is generated, Client information such as mac id,serial number,phone number etc etc is also send to verify the legitimacy of the caller and this is why your cell phone company knows when you roam etc etc. So now, your information + "Hey;how you doing" is nothing besides a signal generated through your transmitter and emitting that signal through the cell-phone antenna in the form of an "Air-Wave" so called "Spectrum". For instance, 850 MHz or drop a stone in a water creating waves and give it a name through the distance it travels/sec or count the number of oscillations withing the given distance. It may be 2 cycles so, 2Hz/Sec. Difference is, radio waves oscillate super fast thus, 850 Mega Hertz/sec. Each Cycle in a radio-wave is an analog signal generated through your transmitter traveling to the nearest cell phone tower. Now, cell phone tower will convert that Analog signal carrying your information along with "Hey;how you doing" into a digital Signal accordingly. Your information goes thru Carrier-Servers/Network and identifies your identity that you have paid your bill on time etc etc and then your gf number which now is also connected to the nearest exchange. This place in video just simply route your call to the nearest exchange in which your gf cell phone tower keep communicating (reception). Damn!!!!
Please pardon some typos. Too Tired!!!! These guys in the videos are highly paid engineers making over 100K. Also, they don't have a permission to disclose any confidential information. As you can tell through the noise that, those are servers and hearing the cooling fans at the background. Voice signals dont require massive infrastructure. These massive servers are for data routing.
@deejoe233 Nothing you just said makes any sense. It's like you found a bunch of random words, squeezed them together, and pooped them out with the hope that it would sound clever.
Also I want to see AT&T's MTSO with their GSM switching equipment (their upgraded GSM eNodeB's for LTE and NodeB's for GSM/UMTS/HSPA+) is similar to VZW's LTE stuff. Interesting Ethernet attachments for intra-VZW MSC trunking. No wonder unlimited calls! VZW is trunking intra VZW to VZW MSC via Carrier Grade VoIP (EVRC/EVRC-B!) over the GigE and 10GigE circuits! Hopefully their diversely routed!
many dumb questions. also do you have to repeat everything the employees say. Nice idea to show backend but be better prepared for intelligent questions
Wow, the smug was so thick with those Verizon suits. Yeah they have infrastructure on the East cost (the old NYNEX ILEC) but not so much out west. Where I live, they're the only MNO that's totally dependent on CenturyLink, and CenturyLink has this habit of going down everywhere when one network card is misconfigured. So much for reliability...
ram130, cause VZW wants the superior voice voice quality. That's why they deploy 1X carriers @ 800MHz and 3G EVDO rA carriers @ 1900MHz. Remember the "nation's most reliable!?" yeah that... AT&T's GSM 3G is newer in that they can do dynamic power/signal load balancing on their newer upgraded sites (and soon Sprint CDMA with Network Vision) in that if you are indoors it switches to 800/850MHz but outdoors close to site is 1900MHz. (Balancing in-door coverage & capacity). VZW's 4G is the newest.
You just have to love the way those switch engineers talk. Not a clue about shit lol. At least we core engineers know that if we touch anything it gets fucked lol
@ulukita: I was amused by that--always selling. He was a pretty technical guy though, so it was interesting that he seemed genuinely excited to be asked about the new spectrum acquisition. It was as if he wanted to say "Oh yeah! And we plan to use it!" I'd guess that LTE phones supporting both 700MHz and AWS frequencies will coming relatively soon now. AT&T should have bought the licences before Verizon did. Instead, AT&T wasted time and resources messing around with T-Mobile.
Interesting MSC... BTW VZW, I assume with the legacy 1X/EVDOrA (DOrA) in the urban areas you guys are using IP RAN now to increase efficiency!? Also I assume your using trans-coder free operation (TrFO) to allow for your BTS/NodeB (Yeah I know its still BTS in CDMA2000!) to send you the raw erlangs of the EVRC/EVRC-B to your RNC!? IP RAN = Definitively on the 4G LTE. Probably the new stuff is Verizon's EPC (Evolved Packet Core) with their eHRPD to combine it with their legacy 3G.
Unlike CDMA, GSM is a broad group of standards, ranging from post 1G, to advanced 4G standards of wireless communication. What you are saying is like comparing a car model to an entire car lineup, apples vs oranges, it doesn't work.
I wish he asked what causes disruptions to the service (for example: what happened the past few days when 4G was down across the country). Also, I wish he asked if they can run the facility off of diesel indefinitely or if that is limited by some other factor.
Thank you for this video Brandon. That was intriguing, no doubt. The man with glasses, I assume the head of the switch, almost put up the four finger quote for the word 'benefit' when he stated, "That's how we're able to extend that--benefit to the customer." Interesting.
Some folks here are wondering why the guys with ties are not telling much....That stuff is top secret corporate info. Are you going to tell your competitor how you built your telephone system?? And there needs to be security from nut case folks who want to destroy our comm systems. Radio frequencies will never be as fast as light waves.
No it's not secret. It's build from parts anyone can buy or play with. If you have a richie rich;) And if you study telco you can "play" with it in the lab in order to get basic principles of operations. There are public lectures about it and vendors offers study materials to anybody. Phone networks always worked with the same principles and same design. What was different was a specific implementation of that principle eg. different equipment or different underlying architecture level. Today phone systems are not national secret. Even local connections are publicly held in public databases to support safe distance during construction works such as road repairs or excavation. And as you probably know submarine cables are also publicly available in marine maps. Some parts of the network such as physical connections between equipment,cable border crossings,equipment location inside facility (especially government spying devices) may be secret. But that's all.
Possible over the air, sure. But once it gets back to where they were, voice calls are circuit switched, and data is packet switched. All those rows of cabinets in that one room was a Lucent 5ESS telephone switch. All it does is route calls to the rest of the public switched telephone network. (They didn't even cover the data part.) Today there are more voice calls that are packet switched end to end, just like any other data. But back then there was a huge entrenched infrastructure for voice using SONET and other TDM technology.
vorkev1 Is call MIMO is two transmitter and two receivers to achieve 100MB Downlink the Antenna on the tower is One with MIMO path inside so there is 4 antennas in one.
1xRTT is 3G. The reason why you get only 1xRTT indoors is because the narrow RF bandwidth has better power density. Better to be able to make voice calls than have nothing.
Yea great, 4G in the USA. Its just 3.5G technology, not the actual 4G. So the US 4G network works at the same speed as the 3G network we've got in Europe. Brilliant xD
Scrolling down through the comments, i realized i'm not the only one who noticed he got taken for a run. Still cool to see i guess.
I dont trust anyone who wears a tie. I dont think they wanted to tell you anything, Nice try tho.

Now we are moving towards 5G. Goodbye 3G.
the switch tech was horrible. I am a cell tech for "Run Fast" and only about half that was stated was accurate...
Yeah I get the feeling their been warned not to say too much lol.
Do you think?
I'm a cell tower technician and I even had to sign an NDA. Guaranteed he can't disclose much info either.
Its like this at any data center. Can't even really take photos. People finding out the orientation of the equipment gets these guys nervous
Ah...gold old Verizon managers...not a clue in hell about what they are doing! :D

Cool. Thanks to the Verizon employees who took the time to show us around, and thanks to the interviewer for sharing this fascinating experience.
I guess he meant "microwave backbone" or "fibre backbone" when he said "cloud"
Watching on 5G
would love if you guys made one for sprint, and having them explain and show us the new network vision upgrades theyre deploying in 2012.
Verizon hates guys like me...I use up to 300gb per month ☺️
Maybe not if you spend a lot of money on data.

@wpgeek nice break down. Do you have any explanation why Verizon keeps their 3G network on 1900mhz and not go lower? Thanks..

tentacles?? are u fucking kidding me?! the things that hold the antennas in place are called "racks". wow.
How many MAC channels does a tower have? Cause users on MAC channel can be viewed on some phones and it rarely goes over like 40-60
u should do a video with AT&T and ask them why they don't invest in there network, can u say bonus for boss and crap for consumer
old vid. but there shotgunning lol.. old timer computer guys will know what it meens ...

Actually, simultaneous voice and data is possible on CDMA. look up SVDO. some verizon phones already support that

That’s the lawyers in the background
so maney lies but the biggest is when he sys lte requires 4 antennas for it to use 100mb and that is not true
vorkev1 Is call MIMO is two transmitter and two receivers to achieve 100MB Downlink the Antenna on the tower is One with MIMO path inside so there is 4 antennas in one.
nice i love information about 4g lte core engineering
this video explaned everything I have ever wonderd bout a cell network
what is different between CDMA and GSM
Great video. I wish you asked why they kept 3G on 1900mhz? my phone always switching between 3G and 1x once inside. Can you ask them next time? Thanks
1xRTT is 3G. The reason why you get only 1xRTT indoors is because the narrow RF bandwidth has better power density. Better to be able to make voice calls than have nothing.
good video i would like to see more from all the carries
