For the first time I noticed some small cells in West L.A. So far, the parts of the city that have multiple deployments include: Koreatown, parts of Hollywood, NoHo and now West LA. There's probab

I am failing to see the point of posting repetitive bad 3G speed tests. We all experience poor Sprint 3G performance in many places on the network. Help me to understand how this is helpful or goes

1x800 in Hawaiian Gardens! As close as I have seen to SBC so far. Might just be testing because it keeps going back and forth to 1xRTT.

Kudos to the person who captured LTE signal on his/her commute on the Riverside Metrolink. Or I should hope it was a commuter and not the conductor. :D

There is a purple strip that stretches from just East of Union Station at the beginning of the Cesar Chavez railyard to the 101 freeway. This purple strip covers the rail line which the Riverside Metrolink uses.

Its been really fun messing around with LTE these last few days. First, Not sure about the GS3, but the signal on the iPhone shows signal for that connection. If connected to LTE, it will show LTE signal strength. And, if you switch to 3G it reverts to that signal strength. Ive noticed that where I get LTE (say 3 or 4 out of 5 bars on my iPhone), and I turn off LTE, I have full bars on 3G. And consistent speeds of 1.5+ mb. About 1mb of upload too, its pretty nice. Though, it seems that LTE doesn't penetrate as well as 3G does, despite both operating at 1900mhz. In my apartment, literally RIGHT across the street from where I have 4 bars of LTE on my phone, I dont get LTE. I want to blame my apartment, especially since my Epic 4G Touch had AWFUL reception issues in my unit due to poor Samsung radios, where my iPhone does not. BUT, I get 3G on the iPhone. Ahhh, atleast I have 50mbps Wifi Lol

It's not that LTE doesn't penetrate as well, it is that LTE is not usable with as weak of a signal. LTE 1900 and CDMA 1900 will be the same signal strength at the same distance from the same site. However, LTE maxes out around -95dBm RSSI and CDMA will go to about -105dBm. And going indoors usually results in a 8 to 10dBm signal loss. And even more with some types of buildings.

 

Also, there is a good chance that the tower that you are connected to 3G to is closer than the tower you are connected to LTE on.

I didn't know that, thanks for clarifying. I definitely feel im connected to the same tower with both. Though, Ive noticed that the LTE signal on my phone is VERY faint in my apartment, and it seems as if it may try and connect, but then just reverts to 3G. So, your reasoning sounds very accurate.

The best way to try to determine if you are connected to the same site for 3G and LTE is to get the dBM readings for both in your debug menu. I'm not exactly sure how to do that in an iPhone.

 

However, if you can get your RSSI reading for 3G, and then your RSRP reading in LTE, then add 25 to the RSRP number, then you have an apples to apples signal comparison. If they are similar after you add 25, then they are likely from the same site. If they are more than 5dBm apart, then probably not.

Network Vision/4G LTE is gonna be upgrade in every single sprint site(they said) so being that true LTE coverage will be bigger many times than Wimax...Wimax was only deployed on important areas,urban areas. ALSO i dont think Los Angeles will be 100% by march..now it is not even 50%.

Still waiting for lte in Hawthorne gardena Torrance areas. Can't wait to start mapping it

 

No joy in Torrance around The Crossroads Shopping Center. I went to Costco to fill the car tank and only 3g in the area.

This is very disappointing news. I am averaging -105dBm in my house right now.

      Network Vision/LTE - New York City Market

      Good catch! I meant 115932/119932. Edited my original post I've noticed the same thing lately and have just assumed that they're skipping it now because they're finally able to deploy mmWave small cells.

      T-Mobile LTE & Network Discussion V2

      By Dkoellerwx · Posted

      At some point over the weekend, T-Mobile bumped the Omaha metro from 100+40 to 100+90 of n41! That's a pretty large increase from what we had just a few weeks ago when we were sitting at 80+40Mhz. Out of curiosity, tested a site on my way to work and pulled 1.4Gpbs. That's the fastest I've ever gotten on T-Mobile! For those that know Omaha, this was on Dodge street in Midtown so not exactly a quiet area!

      Did you mean a different site? eNB ID 112039 has been around for years. Streetview even has it with C-band back in 2022 - https://www.google.com/maps/@40.7303042,-73.9610924,3a,24.1y,18.03h,109.66t/data=!3m8!1e1!3m6!1s2ossx06yU56AYOzREdcK-g!2e0!5s20220201T000000!6shttps:%2F%2Fstreetviewpixels-pa.googleapis.com%2Fv1%2Fthumbnail%3Fpanoid%3D2ossx06yU56AYOzREdcK-g%26cb_client%3Dmaps_sv.share%26w%3D900%26h%3D600%26yaw%3D18.027734930682684%26pitch%3D-19.664180274382204%26thumbfov%3D90!7i16384!8i8192?coh=205410&entry=ttu Meanwhile, Verizon's eNB 84484 in Fort Greene has been updated to include C-band and CBRS, but not mmWave. I've seen this a few times now on updated Verizon sites where it's just the CBRS antenna on its own, not in a shroud and without mmWave. Odd.

      Dish Network/Boost Mobile cell/5G buildout thread

      By dkyeager · Posted

      Drove out into the country today.  Dish stuck to my phone like glue. At least -120 rsrp. Likely only good for phone calls (should have tested.) It then switched to T-Mobile. Getting back on Dish was another issue. I am used to dragging out coverage so I expected a few miles, but had to drive at least 10 miles towards a Dish site. Airplane mode, which worked for Sprint, did nothing. Rebooting did nothing. Finally got it to change over about 2 miles from the site by manually setting the carrier to Dish then it had great reception. Sprint used to have a 15 minute timeout but I did not have the patience today.  Previously I did a speed test on Dish out in the country at the edge of Dish coverage. My speeds were 2g variety. Dish has really overclocked some of these sites. Seen rssp readings in the 50s. Would have called them boomer sites with Sprint but much  more common with Dish.
