need bb Posted April 15, 2012 Share Posted April 15, 2012 Sprint recently upgraded one of its towers in the center of Westborough, MA. I went and took some pictures which I uploaded to my website, www.danlampie.com, along with a quick article about Network Vision. I don't have any performance information but it does apear that Sprint is going with narrower beam antennas...probally 65 degrees. This should help increase the SNR, at the expense of reduced coverage in the nulls where the antenna patterns overlap. This is an Alcatel-Lucent market and they installed three RRH per sector, so I was thinking two RRH for PCS and one RRH for 800MHz. It appeared the only two (the PCS band) of the three RRH were powered on, so I am thinking that 800Mhz 1X advanced carriers would be coming a little bit later down the road. The old coax was cut, but the old antennas were still mounted. I wonder why the old antennas were not removed when they were already doing work on the tower. 5 Quote Link to comment Share on other sites More sharing options...

I actually came across your website and read your posting earlier in the week. Sprint has a combined 800/1900 panel in Network Vision. They are not separate anymore. The large one in the middle of each sector is the new NV panel. It is connected to the RRU. The smaller ones out at the ends are likely legacy panels. They will be removed later. Typically 30 to 45 days after all the work on the site is complete. At most sites, 800 CDMA will go live on Channel 476 later in the year, but not at initial NV deployment. They are still clearing iDEN out of the way to free up Channel 476 for the new 1xA carriers being installed in NV. Respond with the exact location of this site, either GPS coords or nearest cross streets and I will tell you some more schedule info on this site. And welcome to S4GRU!

lrmcgarvey Posted April 15, 2012 Share Posted April 15, 2012 Very nice. You got some really good pictures there too. Thanks for sharing! Quote Link to comment Share on other sites More sharing options...
need bb Posted April 15, 2012 Author Share Posted April 15, 2012 Hi Robert, Thanks for the info. Clearing the Nextel spectrum makes sense why the 800MHz RRH was powered off. This means the LTE RRH was powered on, but I had no was to test whether it was radiating. The site was: 25 Brigham St, Westborough, MA 01581.

The old coax was cut, but the old antennas were still mounted. I wonder why the old antennas were not removed when they were already doing work on the tower. It's amazing how many wires are running everywhere. I wonder if there are any reliability differences with the RRU's mounted on the tower. It seems like you could have multiple places were gaskets and such could wear out causing failure. The Ericsson solution that Duffman posted where the RRU was mounted inside the antenna housing was downright sexy - I wonder what the cost and reliability differences are between them. I wonder what the cost difference is for mounting the RRU up on the tower is vs. on the ground. Quote Link to comment Share on other sites More sharing options...
WiWavelength Posted April 15, 2012 Share Posted April 15, 2012 I wonder what the cost difference is for mounting the RRU up on the tower is vs. on the ground. If it is on the ground, then it is no longer an RRU. AJ Quote Link to comment Share on other sites More sharing options...
irev210 Posted April 15, 2012 Share Posted April 15, 2012 If it is on the ground, then it is no longer an RRU. AJ err, oops! Good point. I imagine that the amount of wires so high up means a good chance of higher maintenance costs, longer install times, etc. Imagine if you have a bad connection and you need to send someone up the tower to replace it instead of just to the base station. I wonder if Verizon decided that it just added too much time/cost for the benefit when they are using such good spectrum to start with.

gumby420h Posted April 16, 2012 Share Posted April 16, 2012 i wish i could get all that infor on my address lol i make advanced tech tell me some but they dont know all of it or how to acess some of it and some are afraid to get in trouble lol my zip is 60433 if any one can look it all up Quote Link to comment Share on other sites More sharing options...

But if you are in Joliet (I am guessing from your profile), then you are in an active Network Vision area. Some of the sites on the west side going out toward I-55 have already been converted. There are maps in our Sponsors area that show details of where. Robert Quote Link to comment Share on other sites More sharing options...
briankwest Posted April 17, 2012 Share Posted April 17, 2012 (edited) iDEN is not part of Sprint's NV plan. I wish they would have started the turn down faster ... COME ON SPRINT launch already. /b Edited April 17, 2012 by briankwest Quote Link to comment Share on other sites More sharing options...

legion125 Posted April 17, 2012 Share Posted April 17, 2012 Here's a slide show from an official Sprint briefing/tour regarding NV sites. http://www.fiercewireless.com/slideshow/touring-sprint-network-vision-cell-site?img=3 Quote Link to comment Share on other sites More sharing options...
S4GRU Posted April 18, 2012 Share Posted April 18, 2012 my addy is 1720 aspen lane joliet il 60433 if that helps you Posted below is a map of Network Vision sites that are complete in the Joliet area. As you can see, there are a lot of them. Sponsor members have access to all the completed NV sites maps and can zoom in and pan around. As well as more than 100 other maps.
