I've noticed some sites in Tucson are being set up with 2 RRUs per sector, while others are receiving only one RRU per sector. Was it ever determined if current Alca-lu RRUs can run CDMA+LTE? Are they possibly skipping LTE deployment on otherwise full-build sites?

Yes, AlcaLu re-certified their RRU's for dual-mode CDMA/LTE about 2 months ago, so don't be surprised that you only see 1 1900MHz RRU per sector.

That's correct. A low capacity site in Tucson could have as few as one RRU per sector. It will not receive a second RRU until either 800 is approved for use or they needed more than four LTE/CDMA carriers combined on the site. The AlcaLu 800 and 1900 RRU's both run CDMA and LTE together.

So if AlcaLu's RRUs can run both modes, can the other OEM provider's equipment do the same?

In the beginning, only Samsung could run both CDMA and LTE on the same RRU. Now all three OEM's can do that.

But yet I see Ericsson still rolling out 4 RRUs on sites. Not going to complain one bit though as that just makes things easier in the future.

      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.
