Network Vision/LTE - New York City Market

Fun fact, while taking my Uber today I found out T-Mobile doesn't have service in the Battery Tunnel. Meanwhile Sprint has Band 26 down here and I'm posting this while on it right now. It might be leaky coax or a DAS because the signal is really strong.

Carriers put DAS in tunnels?

Carriers put DAS in tunnels?

Sometimes, or they use repeaters if applicable. Pittsburgh does in a few of its tunnels, but they aren't updated for LTE yet. San Francisco finally does on all the underground portions of the BART (subway), including the tunnel that goes from San Francisco to Oakland under the bay. DAS is becoming more and more popular and we're starting to see them in a lot of places. There are a lot of ODAS installations as well. The distinction between ODAS and DAS when it comes to tunnels is a bit blurry, I guess it just depends if the antennas are weather proofed or not?

I just ran a speed test in my house and got a ping of 23ms with speeds of 13Mbps down on at -112dbm. It's kind of amazing because in the younger days of Sprint LTE, I struggled to hold onto even Band 26 in parts of my house. Now my house is covered in Band 41.

Since this small cell was broadcasting on EARFCN: 40072, 1 week ago, this week it changed to 41078, 41276 and 41474. I uploaded data on cellmapper by me. I only upload data for lower manhattan.

This looks like 2xCA coming from the small cell, first time ive seen that. Did you do a speed test? did you notice any increase in speed?

Yes, but I was on my work break at 16th floors, 22.99 Mbps Download speed and 8.80 upload and ping 19ms. The image is too large to upload.

Looks like these EARFCN are contiguous, if I'm not mistaken small cells are limited to 2xCA, but this does signify that 3rd carrier is incoming. Did you pick up all three EARFCN's from the same site? and how did you confirm it?

Yes, it keep on changing on my Service Mode from first EARFCN 41276, the SCC1: keep changing between 41078 and 41474.

There also another small cell that have 3 carriers broadcasted. GCI: 0129DB31 PCI: 485 and GCI: 0129DB39 PCI: 485.

GCI: 0129DB31 was broadcasted EARFCN: 40072 only, now it has the same EARFCN as my first one.

Mini macros and picos do not support more than 2x20 or two 20 MHz LTE carriers. Only 8t8r macro equipment does and the third carrier gci ends on 41/42/43 if so.

My bad the pci 459 only broadcast 41474 and 41276 while pci 485 broadcast at 41078 and 41276 these small cell very close to each other in M15 SBS south ferry terminal.

Hey folks, saw this just a minute ago. Maybe related to what the observant user up top discovered and the ensuing channel moveage and findetry discussion. Not being local I checked le map and, as I assume you know is in Manhattan. What a rollout, small cells and then aggregation. Great times to be a Sprint user in the area. Hope this helps.

Have a great night everyone.

Our new @Sprint #LTEPlus system is now on-air w/ two-channel carrier aggregation (faster data speeds!) @PABusTerminal in #NYC

Nice find, but this sounds like DAS in port authority which is a huge bus terminal. I havent been there in a while but its awesome to see it come online.

In Staten Island and my aunt's Galaxy S6 Edge is getting speeds of 56Mbps and pings of 21ms. Pings that low aren't common at all in Boston.

 

I thought we determined that Boston LTE backhaul is out of a 4G core in New York. Or was it Roachdale?

I have one question, why does some clearwire(sprint) sites only broadcasting single band 41 instead of 2x20 mhz? Other clearwire(sprint) site have 2x20mhz, with GCI ending 00,01,02,09,0A,0B

This is the speed test image from the 16th floor.

This is the another speed test image when waiting at the bus stop at south ferry terminal at 3:30 PM. 2x20mhz small cell really does have with capacity and bandwidth.

Optimization can do wonders..

I can gain small cell at work, but I can't gain small cell from my home apartment complex. The highest speed I can get -97 RSRP 2x CA band 41 8T8R is 50 Mbps down and 15 upload at 4:30 AM and 26 Mbps down and 8.5 upload on band 26 on -89 RSRP and band 25 -97 RSRP.

    • So, in summary, here are the options I tested: T-Mobile intl roaming - LTE on SoftBank, routes back to the US (~220ms to 4.2.2.4) IIJ physical SIM - LTE on NTT, local routing Airalo - LTE on SoftBank and KDDI (seems to prefer SoftBank), routed through Singapore (SingTel) Ubigi - 5G on NTT, routed through Singapore (Transatel) US Mobile East Asia roaming - 5G on SoftBank, routed through Singapore (Club SIM) Saily - 5G on NTT, routed through Hong Kong (Truphone)...seems to be poorer routing my1010 - LTE on SoftBank and KDDI (seems to prefer KDDI), routed through Taiwan (Chunghwa Telecom) I wouldn't buy up on the T-Mobile international roaming, but it's a solid fallback. If you have the US Mobile roaming eSIM that's a great option. Otherwise Ubigi, Airalo, or my1010 are all solid options, so get whatever's cheapest. I wouldn't bother trying to find a physical SIM from IIJ...the Japanese IP is nice but there's enough WiFi that you can get a Japanese IP enough for whatever you need, and eSIM flexibility is great (IIJ as eSIM but seems a bit more involved to get it to work).
    • So, the rural part of the journey still has cell service for nearly all the way, usually on B18/19/8 (depending on whether we're talking about KDDI/NTT/SoftBank). I think I saw a bit of B28 and even n28 early on in the trip, though that faded out after a bit. Once we got to where we were going though, KDDI had enough B41 to pull 150+ Mbps, while NTT and SoftBank had B1/B3 IIRC. Cell service was likewise generally fine from Kawaguchiko Station to Tokyo on the express bus to Shinjuku Station, though there were some cases where only low-band LTE was available and capacity seemed to struggle. I also figured out what I was seeing with SoftBank on 40 MHz vs. 100 MHz n77: the 40 MHz blocks are actually inside the n78 band class, but SoftBank advertises them as n77, probably to facilitate NR CA. My phone likely preferred the 40 MHz slices as they're *much* lower-frequency, ~3.4 GHz rather than ~3.9, though of course I did see the 100 MHz slice being used rather often. By contrast, when I got NR on NTT it was either n28 10x10 or, more often, 100 MHz n78. As usual, EMEA bands on my S24 don't CA, so any data speeds I saw were the result of either one LTE carrier or one LTE carrier plus one NR carrier...except for B41 LTE. KDDI seems to have more B41 bandwidth live at this point, so my1010 or Airalo works well for this, and honestly while SoftBank and NTT 5G (in descending order of availability) have 5G that's readily available it may be diminishing returns, particularly given that I still don't know how to, as someone not from Hong Kong, get an eSIM that runs on SoftBank 5G that isn't the USM "comes for free with the unlimited premium package" roaming eSIM (NTT is easy enough thanks to Ubigi). In other news, I was able to borrow someone's Rakuten eSIM and...got LTE with it. 40 Mbps down, 20 Mbps up, 40ms latency to Tokyo while in Tokyo...which isn't any worse than the Japan-based physical SIMs I had used earlier. But not getting n77 or n257 was disappointing, though I had to test the eSIM from one spot rather than bouncing around the city to find somewhere with better reception. It's currently impossible to get a SIM as a foreigner that runs on Rakuten, so that was the best I could do. Also, I know my phone doesn't have all the LTE and 5G bands needed to take full advantage of Japanese networks. My S24 is missing: B21 (1500 MHz) - NTT B11 (1500 MHz) - KDDI, SoftBank B42 (3500 MHz) - NTT, KDDI, SoftBank n79 (4900 MHz) - NTT Of the above, B42/n79 are available on the latest iPhones, though you lose n257, and I'm guessing you're not going to find B11/B21 on a phone sold outside Japan.
    • T-Mobile acquiring SoniqWave's 2.5 GHz spectrum  Another spectrum speculator down! T-Mobile is acquiring all of their BRS/EBS licenses and their leases. Details are lacking but it looks like T-Mobile might be giving them 3.45GHz in exchange in some of the markets where they're acquiring BRS/EBS to sweeten the deal and stay below the spectrum screen. Hopefully NextWave is at the negotiating table with T-Mobile so NYC can finally get access to the full BRS/EBS band as well.  — — — — — Edit: Turns out this is a spectrum swap where T-Mobile is basically giving them DoD spectrum in a bunch of markets in exchange for all of SoniqWave's BRS/EBS. SoniqWave will likely turn around and sell the DoD spectrum to AT&T whenever the FCC removes the 40MHz cap.
    • Maybe. The taller buildings on one side of the street all have Fios access and the NYCHA buildings are surrounded by Verizon macros that have mmWave. I don’t think this site will add much coverage. It’d be better off inside the complex itself.
