While commuting to work this morning on MetroNorth, the railroad put a copy of their monthly newsletter on all the seats. Interestingly enough, they officially stated that cell service is coming to the Park Avenue tunnel. This tunnel is the main artery between Grand Central and the outdoor world, and all MetroNorth trains travel through it. Interestingly enough, the big carriers have contracted Ericsson to provide the cell coverage throughout the tunnel and public WiFi in the terminal. AT&T, Sprint, T-mobile, and Verizon are all funding the project and it will take up to two years to complete. This announcement will soon be posted on MTA.info under the MetroNorth Mileposts section, but I was able to find an earlier report here: http://gothamist.com...g_to_grand.php

 

Will this be a good thing for commuters or will it turn out to be annoying with people screaming "I'm in the tunnel can you hear me?" into their phones? Only time will tell!

The link should work now. The period at the end screwed up the link. Anyway, Sprint is part of this. I think it will be a good thing too, as long as people do not abuse it. Will be nice to be able to stream radio now in the tunnels and continue to work if needed.

I have been a victim of links with punctuation directly after them. :doh:

Is it really that difficult to deploy cells in transit tunnels? I don't understand why subway coverage isn't widespread.

 

If you've ever seen the NY subway system, the infrastructure there is probably order than both of us. I can imagine how hard it would be to run antennas and repeaters throughout the stations without affecting service.

I am not signal guru, but the tunnels have metal framing (steel probably?), which probably absorbs a good deal of the signal. Also, within the tunnels, space is limited, so fitting the required equipment might also be tough in some areas. Another planning nightmare is that the system runs 24/7 365 (unless there is a hurricane), which means there is not a lot of down time to deploy the network. Sure there is the FastTrack program that suspends a select line at night for a few nights, but this is mainly for track and station work. The MTA also requires any outside contractor to attend training to work in the tunnels. Thus, cell operators were probably not in any hurry to install below ground.

Stupid FastTrack screwing up my weekends on the 7 train.

I know part of it is finding the room to store the equipment, especially in NYC where the system is so old and was never designed for the amount of telecommunications and electrical components we have. You can see this in pictures of the original tunnels, without 4,247 pipes per station, and current looks of stations. There isn't a lot of available space underground to build new telecommunications rooms. And, those rooms need to be air conditioned, as they discovered with the countdown clocks shutting down in extreme heat.

Not to make this a MTA NYCT Discussion but the weekend work on the 7 is to Install "Communications Based Train Control" when the R188 comes out the 7 will be computer controlled for hopefully more trains during rush hour.

I just hope that means more local trains. I've been at the 40th street / Lowery St. station and had to skip a few trains because they were packed.

      I have Sprint and still on the framily plan if you can believe that. I am thinking about the new SE because its cheap mostly.
      For now should I get a Sprint phone or the T-Mobile version and just run it on Sprint? Current coverage here is spotty. If I go to my favorite Taco Bell I get 2 bars of strength but I can't even use the app to order until I drive a block north. I worried about included bands working now and some becoming obsolete in the future.

      Even though Sprint doesn't have the best coverage in my area. I do have lots of memories and nostalgia with the company. I wonder who else here will miss Sprint besides me?

      I'm new to this forum, and I've seen people mention cell sites with specific ID's (for example, SF33XC664). Is there any significance to these ID's, and is there a way to decode them? Also, how do I figure out what the cell site ID's are for towers near me?
      Thanks! I'm excited to start talking on this site more 😀

      I figured since Verizon's 5G-NR network officially launched it would make sense for there to be a thread for it.

    • If your on an LTE device that’s correct but on a 5g device it doesn’t really matter both will be on the T-Mobile network.
    • Thanks all. SA 5G is not important to me at this point.  The aspects of a Sprint-SIM phone, including having non-keep sites as a fallback is more important to me at this point. If one gets a new SIM card with a new phone purchase (as mentioned in my original post, such as Best Buy providing on Sprint's behalf or requesting it through the My Sprint app), will it be the Sprint SIM by default? (that is, if you don't request a specific type?)  Do TNX SIM cards need to be specifically requested? (either on an existing phone or an upgrade phone that is requesting a changeover to T-Mobile)  Also, for new Sprint SIMs that are not TNX SIMs, will those need to be changed out to a New T-Mobile SIM once the Sprint network is completely decommissioned and New T-Mobile is in place?
    • I had a tech try to switch me back to TMO SIM yesterday -- well, he actually did switch temporarily...and it wouldn't activate (at my home), so he switched me back to Sprint. I'm in the 3rd week of having a non-working phone unless I'm within range of wifi that is fast enough to have wifi calling connected. I had to call the store and explain to the tech that during the screen replacement that I had 3 weeks ago, it appears that an antenna wire was not connected because wifi works fine, but cellular doesn't hardly work at all..and the way it goes is: WIfi calling connects and works. VOLTE will connect and work. LTE will pass data but no voice calls...Roaming won't connect at all. At home, in range of the Airave (B41), i show on SCP that it's on the Airave...but soon as I place a call, it goes from 4 bars, 3 bars, 2 bars, 1 bar...then 1 bar of R...then the call just drops. Same for places where VOLTE doesn't connect and it's just LTE only...has the same behavior.  It's strange that my wife has the exact same phone..and hers will work fine but mine will do the 4-3-2-1, R, then drop.  I explained to the tech in the closest store...detailed my hours-long convos with various levels of tech and online chat..and told her that i just wanted a working phone...so, over the phone, she was nice enough to just order me a replacement. I told her that I had brought the phone in to have someone take it apart and verify everything was connected..but all they did was "run tests" on it and didn't do anything to the actual internals...which doesn't solve the problem. I was forced to use my Firstnet phone for the past 3 weeks and missed a couple of job interviews because the apps I put in were a day or 2 before I had the phone screen replaced due to stuck pixels. So I'm not sure who's tried to call...but unless it's been on wifi calling...they haven't managed to get me.
    • The only thing you get with a TNX SIM is SA. Sprint-SIM phones still have TMo as the primary, with keep sites filling in just like they do on TNX, but non-keep sites are available as a fallback (high priority roaming, basically). Oh, and you get CDMA (including 1x800) as a fallback rather than H+/GSM until CDMA goes away. The benefit of a Sprint SIM will decrease over time, but for non-5G there's still a benefit. You want TNX basically for SA (if you wind up in areas where n71 can reach but B2/66 can't) and NR CA at some point where you can get n71 and n41. That's...basically it.
    • I've found a couple more recently tagged Sprint keep sites that are really close to existing T-Mobile sites. It'll be interesting to see when these get converted if they get everything or mid-band frequencies only.
