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.

Woops, close enough!

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 wispiANt · Posted

      Historically, T-Mobile has been the only carrier contracting with Crown Castle Solutions, at least in Brooklyn. I did a quick count of the ~35 nodes currently marked as "installed" and everything mapped appears to be T-Mobile. However, they have a macro sector pointed directly at this site and seem to continue relying on the older-style DAS nodes. Additionally, there's another Crown Castle Solutions node approved for construction just around the corner, well within range of their macro. I wouldn’t be surprised to see Verizon using a new vendor for their mmWave build, especially since the macro site directly behind this node lacks mmWave/CBRS deployment (limited to LTE plus C-Band). However, opting for a multi-carrier solution here seems unlikely unless another carrier has actually joined the build. This node is equidistant (about five blocks) between two AT&T macro sites, and there are no oDAS nodes deployed nearby. Although I'm not currently mapping AT&T, based on CellMapper, it appears to be right on cell edge for both sites. Regardless, it appears that whoever is deploying is planning for a significant build. There are eight Crown Castle Solutions nodes approved for construction in a 12-block by 2-block area.

      Starlink (1900mhz) for T-Mobile, AST SpaceMobile (700mhz and 850mhz) for AT&T, GlobalStar (unknown frequency) for Apple, Iridium (unknown frequency) for Samsung, and AST SpaceMobile (850mhz) for Verizon only work on frequency bands the carrier has licensed nationwide.  These systems broadcast and listen on multiple frequencies at the same time in areas much wider than normal cellular market license areas.  They would struggle with only broadcasting certain frequencies only in certain markets so instead they require a nationwide license.  With the antennas that are included on the satellites, they have range of cellular band frequencies they support and can have different frequencies with different providers in each supported country.  The cellular bands in use are typically 5mhz x 5mhz bands (37.5mbps total for the entire cell) or smaller so they do not have a lot of data bandwidth for the satellite band covering a very large plot of land with potentially millions of customers in a single large cellular satellite cell.  I have heard that each of Starlink's cells sharing that bandwidth will cover 75 or more miles. Satellite cellular connectivity will be set to the lowest priority connection just before SOS service on supported mobile devices and is made available nationwide in supported countries.  The mobile device rules pushed by the provider decide when and where the device is allowed to connect to the satellite service and what services can be provided over that connection.  The satellite has a weak receiving antenna and is moving very quickly so any significant obstructions above your mobile device antenna could cause it not to work.  All the cellular satellite services are starting with texting only and some of them like Apple's solution only support a predefined set of text messages.  Eventually it is expected that a limited number of simultaneous voice calls (VoLTE) will run on these per satellite cell.  Any spare data will then be available as an extremely slow LTE data connection as it could potentially be shared by millions of people.  Satellite data from the way these are currently configured will likely never work well enough to use unless you are in a very remote location.

      will this work for service in a plane?

      T-Mobile owns the PCS G-block across the contiguous U.S. so they can just use that spectrum to broadcast direct to cell. Ideally your phone would only connect to it in areas where there isn't any terrestrial service available.

      So how does this whole direct to satellite thing fit in with the way it works now? Carriers spend billions for licenses for specific areas. So now T-Mobile can offer service direct to customers without having a Terrestrial license first?
