Okay I know that this will be great for in building coverage but one question, with 1900 spacing I was wondering how much the downtilt would have to be to not cause interference... I ask this question because on the way to work ( I work outside of sprints coverage) I get 800 signal all over my town now been weeks since I've even seen signal check say anything different. But back to my question, on my drive to work I will see my dBm drop from -62 to roaminging in literally 1/2 mile (headed straight south of the cell site nothin to disrupt signal), and this is an area where I'd even have 1900 coverage. I know these towers may still be testing but anyone seeing what I'm seeing?

 

- would the downtilt of 800 on 1900 spacing, cause no real coverage increase just better inbuilding penetration?

Downtilt can be adjusted for each separate antenna element. So, you can have more downtilt on 800 than 1900. Even with downtilt, you still have 800's advantages of matter penetration, and propgation will be better. And severe downtilt is only used in very urban areas, where site density should be enough for it not to matter as much. Should.

Because CDMA1X is used for voice and SMS, only sparingly for data, interference is far less of a concern.  Voice and SMS work fine even with relatively poor Ec/Io.

Has 800 greatly increased your coverage footprint on your way to work?

No see that's the thing my coverage is almost exactly the same the only difference is I have more bars when in sprints area. Its almost like they can't use 800 to its full potential because of interfereance maybe with other sites? This happens every day I go from full bars to no bars in a half mile. Coverage cuts off about the same place it did before too.

Your network is still in testing phase.  Or it has been configured incorrectly.  Plenty of us use CDMA1X 800 for miles and miles through other cells that have not yet had CDMA1X 800 lit up.

We only have one CDMA 800 site live in our area now, but it is traveling 15-20 miles!!! It is broadcasting over 5 PCS sites in one direction. Just amazing.

I also have been impressed with the extreme distance of 800smr 1x. More than I expected.

That's good news for me in Pahrump. :) Great signal in my house for voice would really make things great.

Can "good news" and "Pahrump" be used together in the same sentence?

 

:P

As far as I know, yes. I ignore the existence of those 'things' that make Pahrump famous.

      Are you sure that's Direct to Cell? That sounds like the 911 center was offline and they got brought back online via a Starlink uplink. Which also makes way more sense than Direct to Cell for that area.

      Sprint Super Bowl Coverage/DAS

      February is always closer than you think! https://stadiumtechreport.com/news/caesars-superdome-gets-matsing-deployment-ahead-of-super-bowl-lix/ Another Super Bowl, another MatSing cellular antenna deployment. Caesars Superdome, home of the NFL’s New Orleans Saints, has deployed a large number of cellular antennas from MatSing as part of an effort to increase wireless network capacity ahead of the upcoming Super Bowl LIX in February, 2025. It is the third such deployment of MatSing equipment at Super Bowl venues in as many years, following cellular upgrades at Allegiant Stadium for Super Bowl LVIII and at State Farm Stadium for Super Bowl LVII. According to the Saints, the MatSing antennas were part of a large wireless overhaul this offseason, done primarily “to satisfy fans’ desires for wireless consumption and bandwidth,” an important thing with Super Bowl LIX coming to the venue on Feb. 9, 2025. Each year, the NFL’s big game regularly sets records for wireless data consumption, with a steady upward progression ever since wireless networks were first put into stadiums. https://www.neworleanssaints.com/news/caesars-superdome-transformation-2024-new-orleans-saints-nfl-season-part-1-wifi-upgrades-wireless-cellular During the offseason renovation project, the foundation of the facility's new Distributed Antenna System (DAS) was the installation of 16 multi-beam, wideband spherical lense antennas that are seven feet in diameter and weigh nearly 600 pounds apiece, a model called the MatSing MS-48H180. Another 16 large antenna spheres of varying sizes and frequencies have also been installed for a total of 32 new large antennas, in addition to 200 cellular antennas inside and around the building, all of these products specifically made for high-density environments such as stadiums and arenas. The DAS system's performance is expected to enhance further as it becomes fully integrated throughout the season. The MatSing MS-48H180 devices, with a black color that matches the Caesars Superdome's roof, each were individually raised by hoist machines to the top of the facility and bolted into place. Each cellular antenna then transmits 48 different beams and signals to a specific area in the stadium, with each sphere angled differently to specifically target different coverage areas, allowing increased, consistent coverage for high-density seating areas. In addition to creating targets in seating and common areas throughout the stadium, these antennas create dedicated floor zones that result in improved coverage to the field areas for fans in 12 field-level suites and the Mercedes-Benz End Zone Club, teams and on-field media and broadcast elements. The project is also adding 2,500 new wireless access points placed in areas such as concourses, atriums, suites and food and beverage areas for better WiFi coverage.
