lilotimz Posted March 24, 2019 Share Posted March 24, 2019 As part of Sprints Next Generation Network (NGN) upgrades, Sprint has been actively deploying antenna setups that have a total of 4 individual 800 MHz antenna ports. It was first discovered with the 16 port triband antennas which had four 800 MHz ports, four 1900 MHz ports, and eight 2.5 GHz ports. Subsequently, 10 port dual band 800 MHz and 2.5 GHz antennas also began to appear shortly after in deployments alongside Network Vision era 6 port 800/1900 MHz antennas bringing the total amount of 800 MHz ports in use to four per sector. And for what reason one might ask? It's for 2 Transmit and 4 Receive (2Tx4Rx) diversity for 800 MHz at the cell site. Deploying such an antenna setup enables the eNB to maintain a stronger connection to UE which results in improved LTE data speeds and coverage as the device uplink is almost always the first to fail. This serves as a huge plus in terms of supporting Voice of LTE (VoLTE) as ubiquitous LTE coverage is essential for Sprint as there is no legacy voice fallback. With the these new 8 port dual band antennas, Sprint can now provide more consistent 800 MHz service than two individual antennas provided in the 10 port dual band antenna configuration provided and removed the extraneous 2.5 GHz hardware from the 16 port triband antenna where it is no longer needed. These new antennas will now stand alone next to 2.5 GHz Massive-MIMO antennas or older 2.5 GHz RRH and antenna configurations. Both highly optimized in what they do best.

I think those antennas are also being used in Samsung markets, although it appears they are quite rare. For anyone in the Seattle market who wants to check them out, the two sites are SE73XC022 and SE54XC010. Quote Link to comment Share on other sites More sharing options...
RAvirani Posted July 29, 2019 Share Posted July 29, 2019 For those curious about the antenna specifications, here are their model numbers and links to their spec sheets. RFS Celwave APXVBBLL15X-43-C-I20: http://81.3.15.2/WebSearchECat/datasheets/pdf/?q=APXVBBLL15X_43-C-I20 Commscope NNVV-65C-R4: https://www.commscope.com/catalog/antennas/pdf/part/92966|49723|50693/NNVV-65C-R4.pdf @lilotimz feel free to add these links to the original post! Also, both antennas are used in all vendor regions. The Commscope antenna is used where possible due to its better performance, whereas the RFS antenna is used where there are size limitations. 1 Quote Link to comment Share on other sites More sharing options...
jthawks Posted July 30, 2019 Share Posted July 30, 2019 T mobile has been adding those antennas in Colorado. Quote Link to comment Share on other sites More sharing options...

The antennas T-Mobile is using are different antennas from the same family. The models are: Commscope FFHH-65C-R3 Commscope FFHH-65B-R3 Commscope FHH-65C-R3 (usually a dual-antenna setup) 1 Quote Link to comment Share on other sites More sharing options...
