"What are those batteries for" -T-Mobile
🤣
Since it was AT&T equipment Mr. Sneed was showing us, I can only assume the batteries were for them.
@@realsmt Dude but seriously, T-Mobile has NO REDUNDANCY MEASURES ON SO MANY OF THEIR TOWERS BRO! I don’t know how the FCC hasn’t hit them with hella fines for being unable to make 911 calls from time to time, or send E911 text messages.
That's the thing, they do ding them whenever they have extended outages. It's all cost reduction, they'd rather pay the occasional low cost penalty or fine than force a massive capex to national backup power. They will add backup power at a slow pace their capex can handle and just pay the fines along the way.
@@realsmt It’s ridiculous, especially in Texas where they have a MASSIVE presence, especially with the additional Sprint assets, and they’re burning up energy like you wouldn’t believe. It’s gotten so bad, we have to move away from Texas ASAP, because the costs have ballooned to NON-affordability. Looking into places like Rhode Island, with small populations but capable infrastructure and decent housing, as well as road infrastructure. Rhode Island has awful roads, but the rest is okay.
FWIW, I have worked on the cell networks for two Canadian carriers, Rogers and Wind/Freedom. The first time was on Wind's initial rollout, where I was hired to test the microwave links between sites, where one site would have a fibre connection and nearby sites would connect to it via microwave. Several years later, after they changed their name to Freedom, I was working to upgrade the power at several sites. This included getting those heavy batteries up to the roof of the buildings. At one site it was straight up a ladder, through a hatch on the roof. We had to buy a boat winch and some strut channel to hoist the 4 batteries up to the roof. I also managed the Rogers 4G rollout at several sites, working with Rogers, ensuring materials were ready and more. I also had to update all the relevant records and ensure the techs had done the work properly. One difference I noticed, between Rogers and Wind/Freedom, is Rogers had it's equipment in a shelter, but Wind/Freedom had the radio gear in suitcase sized cases that bolted onto the mast and a cabinet for the power and network connections. Rogers was one of the original cell carriers in Canada, going back to the mid 80s and analog phones. Wind/Freedom started life as a 3G carrier in 2008.
BTW, in a recent test, I was able to get 436 Mb down and 78 up on C band with Rogers.
Rogers is truly the best network, so long as they don’t update their equipment and don’t tell certain folks lol. But yeah, truly an amazing network and one that puts some American networks to shame. Your speeds are amazing, but your costs are eye-watering.
Thanks for sharing, most people take it for granted that our phones just work but never think about the planning and labour that goes on to make it all work! I recently switched to Freedom to try and support the underdog and drive competition since they improved their Nationwide/Roaming.
@@jchtylmegekr When I started with Rogers (Jan. 1995), then Cantel, it was the underdog! 🙂 Back in the analog days there were two carriers, the incumbent phone company (Bell) and the alternate (Cantel). Back then, there was only the 850 MHz band and voice calls only, no data. Also, back then, you had to pay for every call!
I work on the hvac system to keep the shelter cool
Very cool video! Thanks for sharing the footage of the gear that’s inside the shelter. I think the site is going to perform amazing. It should be really fast. Once DOD goes live, should easily be pushing over 1GB with 10 gig backhaul.
Awesome video! Very cool, I’ve never seen the internals of a cell site before. Those look like prismatic LifePo batteries, but not really sure what their capacity might be. I’m curious how much energy that site requires. I bet even if those things are high capacity all that equipment probably really slurps down the juice. lol
Awesome video!
Great close up
Sneed, it ought to be great coverage for you at home. My AT&T home antenna I had sent pics of, was just turned on this week. The upgrade was about 1 week and the city permits etc... took another 2-3 weeks to clear and sign off. I now have 5G+ in my house ... 300-400 dn and 28 up. It's great. It improved about 150-200 dn from where it was before.
Yeeeeeeeeeaaaahhhhhh 🔥
Nice!!
Enjoy chemotherapy in 5-10 years
😂 non ionizing radiation but make sure you hide in the shade. The sun radiates ionizing radiation. There's your chemotherapy junior.
The 4 in a row are one string 12x4 =48 volts x 5 strings . I don’t know if you saw the amp draw? If around 100 amps that should last 4 to 6 hours on battery. Also did att have a backup generator?
Nice video
Nice. I have seen but at least they don't have to splice the fiber like I have to. Lol
10 Gig backhaul. impressive
Where can I get the antenna's that they use on these install's as I am trying to set up a Cellular backhaul up on a mountain and want best Antenna I can get so the signal is clear and plentiful? Any recommendations are appreciated and some Distributors would be even better thanks a lot Sneed Mobile Tech!
The batteries that are there is usally only there to transfer of power so they don't drop service till the generator starts up. Batteries don't carry load very well. Now I don't know what the voltages are to power the antennas but looks like it may only power the cellular site for 24 hours so they either can wait till generator kicks on or make provisions to get a temporary generator there to power.
Yup they are in buffer/float configuration. They power the DC to DC converters if power is lost from the main supply. When this is detected it will be on battery and send a notification of this. If the outage lasts more than about 90 seconds the transfer switch is tripped and the gas generator is switched on. I've seen two types. The efficient but loud engine based ones, and the nearly silent stupidly expensive and horribly inefficient thermoelectric ones. Since the batteries are a buffer as well as backup the changeover is instant unlike a home generator set. ❤
Those batteries may be lead and if so are only 2.2V a piece at 400 to 600AH. If one in a string fails they replace that entire string, a bit surprised by the 8 cell group size though, most of these have a 48v (24 cell string) Ended up with several from a scrap yard that were pulled from a lightning damaged tower site. All were fine went for a 12 pack for solar use. ❤
All those new goodies but still with the old T1 smart jack hangin off the wall. (Doesn't appear to be in use though)
I thought I saw a T1 box off to the side when you were showing pics of inside the cell site? I’m pretty sure they’re using fiber now, but would they still be using some T1 circuits?
Yep old T1
This video was recorded in mid July 2022, so I'm guessing you already completed your speed tests on this AT&T tower?
Not yet.
We don't have batteries on our T-Mobile site lol. They have a generac to power it. Vary nice over the traditional batteries
Batteries ? E-waste much ?
Well Well Well
48Vdc battery racks
whoever terminated the fiber into the BBU ports should be retrained. just saying.
The upgrade was in progress, I’m sure everything has been fixed and finalized now.
@@realsmt lets hope so, Id fail that QV in a heartbeat
Is there a way to switch and lock into a cell tower? If so, do you have a video showing how?
No
I hate to say but customers don't have any Authorization privileges to go to a cell site by engineers
Why not? I had a hard hat on, it was not an issue. Just because you don't like I was there and you hatin 😂
That’s crazy he wouldn’t be there if he didn’t ask. Unless it is a government agency or some trade secret that is involved there is no issue. Him being there is inconsequential. It’s may be awkward but he has more insight than an average customer.
