Sounds like its an isolated incident. I am not surprised if folks that live in certain areas for Network Vision are experiencing some slight problems. I believe he was having problems with an airave version 1 and it was a known issue it has problems with the Photon. The airave version 2 seems to have fixed the problem. I wouldn't worry about too much. If there was a massive outage, I am sure it would have made the news.

Network Vision is not being tested anywhere except for G Block. There is signficiant drive testing that occurs before they finally convert a site off legacy and onto NV. We have also had many members visit sites in Chicago, Boston, Central Jersey and DFW and none have complained of these issues. This doesn't make sense from how NV is being deployed. You would need to have a modified PRL to be experiencing the issues described.

 

Also, someone should probably tell that guy over in the HoFo thread who was complaining about not seeing a map of completed sites that we have one posted here for sponsor members. :)

I found this on the Sprint forums which may give reasoning:

 

"As of 03/25/2012, we have began Network Vision upgrades to various cell towers that service the Chicago Market. During this transition, customers will experience temporary impairments causing increased Drops and Blocks may occur unfortunately. The current ETR listed for completion is June. Stay tuned for more information as it becomes available.

Sprint has let us know that wherever they are messing with NV, there are going to be dropped/blocked calls. They have updated out Network Event Board tool to show a "ticket" on any tower with NV work being done so that we can tell the customer the expected time it should be over and service normalized. Total time per tower seems to be 3 to 5 days.

I can see why at turnover from legacy to NV, people would definitely get dropped calls and data connections. But only at one time. However, that could feel like it is all over the city when it is one tower here, then another tower there. Repeating itself over a thousand times for each tower in the market.

 

Also, the Chicago market will not be anywhere near done in June. So they are going to have to extend that deadline much farther out.

But the big question Dino, is it happening at places we have identified as NV sites?

I might be having the same problem in Los Angeles. I began dropping calls on my drive home on the 110 north before hitting the 5 north. I just check the updated map and noted the site near there was upgraded to NV. It may be coincidence, but I have never had a problem in the past 2.5 years.

I have confirmed it is the NV conversion that is causing major headaches from Chicago west. I suspect we will see lots more issues as other towns convert.

 

However, I suspect it will be just the 3G NV radios that cause the issues now. I know they have lit up 4G NV towers here with no 3G NV radios and we have no problems. I can check Chicago tomorrow again, but I do believe they are firing up 3G towers.

 

Robert, can you confirm?

That is interesting. We had a five day period about two weeks ago when everybody I knew in the area with sprint, including me were dropping calls like crazy.

I think you're right. It only seems to be in markets where 3G NV sites have gone live and not in the markets where only 4G LTE has gone live. They are rapidly firing up on Chicago. And the I-110 corridor in LA too. Sounds like NV 3G deployment is the culprit. I will keep my eyes open to see if I come across specifics about what is at play.

I've seen some engineers working on towers in Downtown L.A. while heading home from Santa Monica today.

Illinois was one of the areas with horrible capacity issues, wasn't it? Maybe Sprint is cutting over 3G towers as they go to alleviate the issue and will go live with 4G LTE later.

Chicago is a spectrum constrained market. Yes.

Found some info.

 

"High block/drop rates: During the migration to Network Vision those customers on the boundary between NV sites and legacy sites will experience a higher than normal block/drop rate. The rate will continue until the boundaries are reduced by the introduction of additional NV sites."

Excellent info. Thanks for a little background. For people outside S4GRU, they must be really confused in Chicago. Because Chicago is not even an announced market by Sprint.

Here are some more stats for Chicago market:

 

Capacity upgrades:

91 to 180 days ago = 298

Last 90 days = 59

Next 90 days = 382

91 to 180 days = 498

 

Seems like a strategy change in there or something. They slowed waaay down and are now screaming.

i wonder why.

We had quiet a few issues on the west side of Elgin, IL. From 3G signal not seeing that strong to calls dropping. I suspected Sprint was upgrading cell towers but i've had no way to confirm. Is there any way to confirm without special equipment?

      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?
