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.

Thanks for the thread. 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!

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.

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.

If it is on the ground, then it is no longer an RRU.

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.

Zip codes don't mean anything to me. 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.

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.

      T-Mobile to acquire UScellular

      By iansltx · Posted

      A heavy n41 overlay as an acquisition condition would be a win for customers, and eventually a win for T-Mobile as that might be enough to preclude VZW/AT&T adding C-Band for FWA due to spreading the market too thinly (which means T-Mobile would just have local WISPs/wireline ISPs as competition). USCC spacing (which is likely for contiguous 700 MHz LTE coverage in rural areas) isn't going to be enough for contiguous n41 anyway, and I doubt they'll densify enough to get there.

      Dish Network/Boost Mobile cell/5G buildout thread

      By iansltx · Posted

      Boost Infinite with a rainbow SIM (you can get it SIM-only) is the cheapest way, at $25/mo, to my knowledge; the cheaper Boost Mobile plans don't run on Dish native. Check Phonescoop for n70 support on a given phone; the Moto G 5G from last year may be the cheapest unlocked phone with n70 though data speeds aren't as good as something with an X70 or better modem.

      Official Tmobile-Sprint merger discussion thread

      By iansltx · Posted

      Continuing the USCC discussion, if T-Mobile does a full equipment swap at all of USCC's sites, which they probably will for vendor consistency, and if they include 2.5 on all of those sites, which they probably will as they definitely have economies of scale on the base stations, that'll represent a massive capacity increase in those areas over what USCC had, and maybe a coverage increase since n71 will get deployed everywhere and B71 will get deployed any time T-Mobile has at least 25x25, and maybe where they have 20x20. Assuming this deal goes through (I'm betting it does), I figure I'll see contiguous coverage in the area of southern IL where I was attempting to roam on USCC the last time I was there, though it might be late next year before that switchover happens.

      Forgot to post this, but a few weeks ago I got to visit these small cells myself! They're spread around Grant park and the surrounding areas, but unfortunately none of the mmwave cells made it outside of the parks along the lake into the rest of downtown. I did spot some n41 small cells around downtown, but they seemed to be older deployments limited to 100mhz and performed poorly.

      What is the cheapest way to try Dish's wireless network?  Over the past year I've seen them add their equipment to just about every cell site here, I'm assuming just go through Boost's website?  What phones are Dish native?
