The rest of the technology implementation we have seen before from T-Mobile, Sprint, Verizon but the implementation of C-RAN is a first for this country. C-RAN as Centralized RAN communicating with RRHs at the remote sites via fronthaul. Now it is my understanding that they have only implemented what they call 5G Evolution but it's really LTE Advanced in a few high traffic sites but I can see them implementing it all over their network. I like the C-RAN technology since it allows you to centralize your base stations in one central location and maybe colocate them with your MSC in a data center, where you can have fault tolerance, large UPS's, backup generators, much easier updating, etc. I believe that it will also lead to educed rents to the tower companies.

 

"Citing network upgrades that include centralized-RAN (C-RAN), 256 QAM, 4x4 MIMO and 3-way carrier aggregation, AT&T is launching 5G Evolution in parts of Indianapolis today.

AT&T said it worked closely with the city of Indianapolis to make sure AT&T’s network and infrastructure are ready to support the “technology of the future” to prepare for things like self-driving cars. The operator invested more than $350 million in its Indianapolis wireless and wired networks during 2014-2016."

This isn't the first instance of AT&T deploying 256QAM or 4x4 MIMO. It's already up in many areas. They just don't toot their horn like Magenta...

well AT&T also has a monster budget compared to TMobile

      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.

      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.
