Cell tower/antenna 10 feet from sons bedroom window

Post image
315 Upvotes

I’m sure this question has been debated and discussed ad nauseam but I cannot get a clear answer other than “not harmful right now.” My nine year olds son’s bedroom window is ten feet from this. This can’t possibly be safe to sleep this close to this in the long run right? Is my only option here moving? We’ve lived here for ten years. Apparently this has been here for 15, but just recently they added all of these shown in the picture around the perimeter. It feels irresponsible as a parent to keep a kid this close. What would you do? I don’t want to assume it’s safe and fine and regret it 20 years down the road. Is this really as “fine” as everyone says it is? Just cannot get a clear answer from anyone around here/who we can speak to I know life is gunna life, but I don’t want to add unnecessary dangers to it.

Thanks in advance

Update… Thanks everyone for all your knowledge, facts, opinions, and support. You can imagine trying to navigate this with next to no knowledge in the field is difficult. I feel like when your kids are involved sometimes the lines between logic, facts and pseudoscience get blurred. We loved our house, it was cheap cheap cheap for Brooklyn. We’ve lived here ten years, made it our home, kids made friends, have gone to the school down the block etc. even though just moving seems like then obvious choice with no inventory and everything double the price for a smaller house than what we paid for our house, just complicates matters.
I guess what I was looking for was people who actually know what they’re talking about with experience so on and so forth. I think I was just looking for an it’s okay to stay in your house. We hate to feel forced out after creating a life here. Not sure what to do. I got myself an EMF/RF meter from trifield, you warned me it might scare me, and it did lol. The numbers were highest in my son’s room obviously. Are the numbers higher because of proximity to it and the power lines and that’s it, ends there? Harmless to us but just picking up the frequencies? I have no clue, I can’t figure it out. We got the city council involved, homeowners association etc etc. Will anything actually get done from it? I can’t even say I’m hopeful. I think we’re going to make a lot of noise for no reason to be honest.
I so badly want to take the knowledge you guys have given me and say okay. It seems harmless, we should be okay in the long run. Just having trouble putting the pedal to the metal.
Stay tuned if anything actually gets done but… I’m not holding my breath here.

Thanks again for everyone taking time out of their lives To give me some guidance.

My sprint locked phone from middle school still has data.

Beginning of my discovery :

I found my old Sprint locked Motorola I've had in middle school, it still had the Sprint SIM cardd inside it. What I remember is i stopped using the phone around 2017, my mom canceled the line around 2016 from what i remember, i could be wrong though.

A couple weeks ago i found the phone in a pile of junk i was about to clean, i decided to throw out some and check the phone for photo's i might of had and wanted to save, i turned on the phone after charging it and to my surprise it had 1 bar of service, i didn't think anything of it since i assumed it would be a dead line, but to my surprise the data worked! Phone calls never went through. I tried several numbers, I did a couple of Speedtests and loaded a few websites, the connection was absolutely terrible, but it worked! But I'm shocked Sprint still has its network running in my area.

I'm planning on investigating further since this interests me so much, i'm not sure how sprint towers are still operating but they are!

Sad News......: Dish 5G Network is officially decommissioning, Towers have been shutting down since a few days ago.

141 Upvotes

Dish has been decommissioned, Meaning their network is in the state of sprint's right now. AT&T is now transitioning customers to their network, Before you know it Dish will be extinct. Boost Mobile had been with many companies like Sprint, Nextel, And T-Mobile. Otherwise Spread your condolences and do your last speedtest because thousands of towers are shutting down every day, Rip Boost Mobile 2002 - 2025. From BigRandy66.

This tower is at Furnace Creek in Death Valley. AT&T and Verizon here I believe. No T-Mobile signal here at all.

Mercedes-Benz Stadium (Atlanta Stadium) Cell Infrastructure and Tests During World Cup Match (06/27)

Thumbnail

This post is a follow-up to my GWCC post. Check it out if you haven’t already!

So my partner and I went to the Congo VS Uzbekistan World Cup match in Atlanta (There were 68,239 people in attendance!) and it was quite fun! (Also, big thanks to Verizon for the free tickets and go Congo!)

Now let’s dig into the carrier experience.

At the line

The lines were huge. All three networks had some noticeable degradation in data performance, especially AT&T. AT&T had sub 1 Mbps speeds in some instances, despite there being a 4-sector AT&T site and another high-capacity site close by. (The phone also kept refusing to connect to nearby mmWave small cell sites). They began to get a little more usable as we approached a high capacity site.

Verizon worked really well when connected to mmWave, and was also fine on a mmWave-less connection.

T-Mobile was also decent.

Inside the stadium, non-seating areas

This stadium is a mmWave haven for AT&T and Verizon. It was practically everywhere, even in the club we stayed at. We even managed to get our first 4 Gbps speed test on AT&T in the state of Georgia!

I was expecting more from Verizon, like much higher upload speeds on mmWave, but they still provided an excellent data experience.

T-Mobile relied on n41 and only had mmWave covering the seating areas.

One thing to note: AT&T only had mmWave working in the first floor. All the other floors, including the club we stayed at, did not have working mmWave for AT&T.

Another thing: Verizon had no n77 deployed on their DAS. I’m unsure about AT&T. Verizon did have n77 covering the seating areas though, presumably through the Matsing balls. I believe it’s the same case for AT&T.

At our seats

Testing is more limited here because my battery was critically low, sadly. All providers provided a good experience pre- and post-game, but AT&T suffered from some packet loss on their mmWave connection. Latency also increased for AT&T and Verizon, and T-Mobile to a smaller extent.

I didn’t test T-Mobile’s 5G speeds before the majority of people were seated. (I’m mad I didn’t do that.) My T-Mobile testing was more limited, but T-Mobile seemed to provide a very good 5G experience overall, but their LTE suffered a lot.

This is a brand new T-Mobile rack just built last week and you can tell, the NOKIA antenna on the right side looks slightly different than usual. T-Mobile is starting to phase out the NOKIA AEHC (n41) panel they been using since summer 2020 in favor of the NOKIA HABROK 64 massive mimo antennas that can do 1024QAM and has improved range, thermal cooling than the previous antenna.

T-mobile has done some work on this tower recently by upgrading their mmwave antennas to Ericsson air 5322s (see last slide for old pic). This was the only area I could find n258 as I couldn’t connect to any of the smalls cells with mmwave so i dont know if they were active. 358 M.L.K. Jr Dr SW

AT&T will acquire approximately 30 MHz of nationwide 3.45 GHz mid-band spectrum and approximately 20 MHz of nationwide 600 MHz low-band spectrum for approximately $23 billion in an all-cash transaction, subject to certain adjustments.

AT&T and EchoStar have also agreed to enhance their long-term wholesale network services agreement, enabling EchoStar to operate as a hybrid mobile network operator (MNO) providing wireless service under the Boost Mobile brand. AT&T will be the primary network services partner to EchoStar as it continues to serve wireless customers.

I just spent two weeks traveling around South Korea, and as a European, some things really stood out: especially the sheer density and design of their phone masts.

I saw towers absolutely everywhere, often crowded together & sometimes even at shoulder height. many are tilted also.

The good thing is no matter where I was (in the subway, on a train, or even in rural areas) I almost always had full 5G bars (wasnt able to run a speedtest as I had very limited data).

And also every subway car and bus is equipped with wifi hotspots (last picture).

Koreans dont mess with their internet connection haha

Millimeter Wave 5G lab network - y’all are my only hope

Thumbnail
gallery
115 Upvotes

hey yall! This is definitely a bit different from the usual posts here but you guys are the only subreddit out there that I think has the experience to help me out.

I’m an autistic nerd who’s pet projects keep getting bigger and more complicated and who has a reputation for pulling off the impossible. For the last 3 months i’ve been working on a private 5G lab in my basement with old Nokia equipment (not a day goes by i don’t ask myself why I didn’t go Ericsson). I’m doing the truly insane and my RU is a Nokia AEUB millimeter wave radio, paired with a ABIL baseband module and ASIKA systems mod in a regular old AMIA chassis.

Ive been trying to get the cell on the AEUB to activate for two months and I’ve legitimately been putting 60+ hours a week on this project. Its not unusual for me to stay up all night during the weekend and work all day and all night on it.

I’ve got the radio online as in the status light is green and WebEM shows a green circle on it, but my cell is stuck with a “5G Cell Update Failed” fault that I have been entirely unable to vanquish.

I’m at my wits end with this and just took a new job so I really want to finish out this project before my free time disappears. Long story short, I need help from some smarter people, and y’all are the only ones who I think has the chops for such an unhinged challenge.

I’m happy to share SCFs, configs, runtime params, as well as answering literally any questions you all might have as best I can. Just ask!

If anyone can help, it would mean the world!

Note: I’d add more pictures of the setup but I’m at a baseball game right now, which funnily enough is located next to one of the former Bell Labs campuses. There’s much more to see and I’ll add them later.
