I know this is a couple years out but I am curious and it keeps me busy while I wait.

 

As I understand it Sprint is rolling out G block LTE in the NV build out with a 5x5 format. Sooner or later the masses will come and more capacity will be needed to keep the service top tier. With the RRU's and upgraded cell site gear make it a lot easier to add additional 5x5 ore even maybe 10x10?

Will new gear have to go up the tower or is it mostly add new cards in the cabinets and some programing/configuration? I hope the RRU's handle the whole PCS band.Is there tons of paper work and permits to file?

It's easy to add capacity if Sprint has the spectrum spare in the market. A new carrier card is really all that is needed in the base cabinet. Existing RRU's and panels can accommodate extra LTE carriers in most instances.

 

Each RRU can handle up to four carriers. Each panel can handle two 800MHz RRU's and up to four 1900MHz RRU's. If the added LTE carrier exceeds the available capacity in RRU's, then a RRU will need to be added. If an added RRU exceeds the available capacity in the panel, then an additional panel could be needed.

I should have picked this up by now but they require a truck roll in June to bring up 800mhz LTE, correct?

Yes. At a minimum, it will require an LTE 800 carrier card to be installed. If that's all that is needed, it would be a very quick visit at each site.

 

What I'm not clear on is whether LTE 800 can share the same RRU as CDMA 800. I had one source tell me it can. If so, it will be much easier. If LTE 800 is required to have its own RRU, then it would require a little more work, but nothing mind blowing. Just an additional RRU added near the panels. It shouldn't require an additional NV panel since the existing panels can handle two 800 RRU's.

 

We will know more probably after the LTE 800 FIT.

When is the FIT being constructed? And this is in North Dokota if I remember correctly?

The last thing I seen on the LTE 800 FIT was supposed to be this Fall in Montana and New Orleans. However, I haven't seen anything on it since May.

I'm surprised there isn't an Alcatel/Lucent 800 LTE FIT.

There very well may be. I haven't heard from the source where I learned about these two FIT's since May.

 

AlcaLu likely will use the very same FIT as they did 3G and LTE 1900. Whereas Samsung and Ericsson had separate 3G and LTE 1900 FIT's.

Nice! Thanks for the info. I take it the RRUs are band specific and the 4 carriers can all be on one 1900MHz RRU.

Is that 4 LTE carriers or do you have to use one for the 3G/1x/voice?

For certain 1x and EVDO carriers can be on the same RRU. But we are not certain if LTE can be on the same RRU as CDMA, or if they must be separate. I'm not 100% sure.

Ok thanks. I know they got a LTE RRU up there somewhere so I guess they could add another LTE carrier on NV complete site pretty easy. This is great when the time comes for more carriers we won't need another 2 year build out.

Here in austin most of the NV towers have 1 NV antenna per sector and 2 or 3 RRU per antenna. There are of course usually 3 sector per tower in urban areas.

 

It would be interesting to see if that changes when they compete the NV transition. Which Sprint market has the most thorough/mature LTE buildout thus far? Do we have any confirmation that legacy equipment or antennas have been removed from any towers in the most "complete" NV markets?

 

I've seen most AT&T towers grow from 2 to 3 to 4 antennas per sector over the last 6 years. Yes i am such a nerd that i pay attention to and remember this stuff vividly. Many of their cellsites had 4 antennas per sector before LTE even rolled out, and they've always been doing 850+1900 GSM+HSPA in most markets.

 

I wonder if it would be advantageous in terms of network quality/capacity for Sprint to add an additional antenna or two per sector when the legacy hardware is removed.

Sprint NV panels can handle as many as 16 carriers and four RRU's. So a 2nd NV panel is only needed on really busy urban sites. Less than 5%.

 

Sprint panels currently have the densest antenna arrangement of any other else deployed. AT&T often has so many frequencies and technologies that they need so many panels.

      Network Vision/LTE - New York City Market

      By Paynefanbro · Posted

      As far as I know it's ubiquitous. Ultimately the network decides if you should use VoNR vs VoLTE but pretty much anytime my phone is in standalone mode and I place a call, it goes over NR.   Yup, it was terrible. After a while, I just connected to the WiFi, and that worked fine at about 90Mbps. I get the feeling that rather than doing a "real" upgrade where they install new antennas, upgrade backhaul, etc., T-Mobile instead installed new radios onto the existing and already overloaded DAS and called it a day, which isn't enough. Compared to Yankee Stadium, where they actually went and deployed new antennas/radios for their n41 upgrade, and you're able to get upwards of 200Mbps at sold-out games, Arthur Ashe really is a joke. What's worse is that the folks in their NOC likely know this already, but no effort is being made to change that. I'm not asking for T-Mobile to deploy mmWave everywhere like Verizon but there is a real use case for it at stadiums.

      Does anyone know how well implemented is VoNR in the 5 boroughs. Does anyone use it? I have an iPhone 15 Pro. Does anyone know if T-Mobile is still working on upgrading their network? It seems like the service has gone down. My phone struggles in parts of the Belt Pkwy, and data is slow.

      I come to the US Open men’s semifinals and finals every year, and I’ve never been able to use my T-Mobile phone successfully. Usually AT&T is the top performer—good to hear Verizon has upped their game.

      One sector down, two more to go — — — — —  I was at Arthur Ashe Stadium for the U.S. Open today and the good news is that there is an n25/41 DAS setup throughout USTA Billie Jean King National Tennis Center. From the "boardwalk" to the outdoor concession area, to inside the stadium; you connect to standalone n41 and n25 everywhere via oDAS and iDAS. The bad news is that in the actual stadium it's beyond useless. While I saw strong coverage as indicated by signal bars and I was able to make calls and send texts, there was no data throughput at all. Running a speed test failed 9 out of 10 times. The only time I got a speed test to work was by switching to LTE funnily enough or by using NSA 5G where the test would initiate via LTE and then n41 would kick in giving me ~20Mbps. T-Mobile has so much traffic on their 5G network that now n41 gets bogged down before LTE. That was a first for me! In the stadium in the same area Verizon got 1.2Gbps on mmWave and LTE kept timing out when trying to test it. My Boost line on AT&T got upwards of 150Mbps on C-band and I know they have mmWave deployed as I saw their Nokia mmWave antennas deployed but I was unable to test it. In the outdoor concession area T-Mobile performed well getting over 150Mbps on n41. AT&T in these areas saw over 250Mbps on C-band and I didn't get the opportunity to test Verizon there. It just seems like 140MHz n41 is not enough capacity for the amount of people inside the stadium. Hopefully T-Mobile is considering deploying n258 to all of these stadiums since they now own that mmWave nationwide. It'd make a world of difference in terms of capacity at these venues.
