Special Case "Tri-Band Antenna" Setup
Deployed for engineering reasons these sites do not deploy a dedicated 8T8R antenna for 2.5 but instead opts for a three frequency antenna that supports 800 MHz + 1900 MHz and 2500 MHz. Due to size constraints for the antennas they limit the 8T8R RRUs to 4T4R mode (4 Jumpers from radios to antennas).

I love that this thread is up because I believe these are the radios that were used to show the 2.6Gb/s lab tests with LTE-A.  But wont these be housed in the cabinet at the base, and not visible?  How will we tell if they are installed?  If I am off base, please correct me, but I do not know as much about this stuff.  

 

Still super excited, and love seeing real photos... are these already being used in spark markets, or is it going to be like the Network vision deployment, with different areas being deployed by different vendors?

These are remote radio heads mounted by the antennas. 

 

No. Current spark markets utilize either Huawei dual mode TDD-LTE / Wimax equipment (which will be decommissioned at the end of the year) or an older model 4T4R Samsung dual mode Wimax / TDD-LTE RRH. NSN will be deploying over all of the Ericsson territory. ALU and STA will deploy over theirs.

ALU and STA will be using their own 8t8r equipment, or will this be used nationwide?

I guess my question is: will the other vendors have the same theoretical abilities as the NSN equipment?  AKA, will the experience be the same across the country?

I'm sure this has been answered and I apologize if it's been repeated but these RRUs don't just hook up to the same NV panels, they need their own panels, correct?

That's correct. NV panels house only 800/1900MHz antennas. The new 2600 antennas will be housed in an additional panel. They may come out with a triple band panel in the future, but that seems unlikely as Band 41 will have considerably different deployment scenarios than the other frequencies. Should be different enough that a completely separate panel will always be warranted.

There are 8 antennas in every band 41 panel, and there is talk of NSN deploying 6-sector sites, meaning we will likely see 2 new panels per existing sector. They should fit perfectly on either side of the Ericsson panel where the legacy panels were.

 

The caveat, of course, is that the site needs to be fully 3G accepted so that the legacy equipment can be removed. This is one of the reasons we're seeing Ericsson hastily going back and doing 3G acceptances all over the place right now.

That is incorrect.

 

Each 8T8R antenna panel has 4 "antennas" and are capable of up to 3 sectors per antenna. All three vendors RRH are capable of 3 sectors per antenna. There is no need for an additional antenna per sector. 

 

The NV site must have 4G capable backhaul available and installed before the new B41 equipment is installed or else they will not do that site. Priority is immediate offloading of capacity from the B25/B26 bands and thus they will target only sites with backhaul available at first.

 

Deinstall of legacy 3G equipment is because Sprint doesn't want to pay for their leases and they contracted several companies to do so within a specific time frame.

Thanks for the correction regarding the panels, but won't they still need to prioritize removing legacy equipment and thus doing 3G acceptances on all the 4G-only sites to have somewhere to put the new panel?

 

Or are you saying they're going to be using a new rack?

Contractors were hired to do deinstalls of legacy 3G equipment within a certain time frame. IIRC it's within 6-12 months after the installation of NV equipment. Most "big tower" racks can handle 3-4 full sized antennas per sector. Some have T bar racks which only support 2 antennas per sector where legacy must be removed. 

 

Either way the legacy 3G equipment must be removed and the hired contractors are now just getting to do it en masse instead of whenever they have free time.

Has there been any report of NSN installs? I would love to see one in the macro.

NSN’s TDD-LTE Radio solution features its Flexi Multiradio 10 Base Station using high capacity baseband platform and high bandwidth TDD LTE 8-pipe radio. This will allow Sprint to provide industry leading speed and performance to its subscribers. The project commenced with Services Planning in late 2013, and hardware is expected to start shipping in July of 2014. The network is scheduled to be on air in the third quarter of 2014.

 

The contract announcement was made at Sprint’s facility in Burlingame, California, on the same day that NSN demonstrated its ability to provide download speeds of 1.3 Gbps. This speed could provide unprecedented service for subscribers, allowing them to download a typical two hour movie in eight seconds or a 45 minute TV show in about one second. The demo used the same radio hardware as will be used for the network implementation.

Thanks, I must of missed that Date. I would assume that Permits would start to show up in the wild in the next month or so? In order to have a speedier rollout.

Permits should be already being applied. Contractors / Sprint just won't pick them up (i.e. Issued) until they are ready to begin the deployment.

Has anyone seen the Andrew/Commscope 8T8R antennas that they plan to deploy at the NSN sites? I can't find anything on those new 2.5GHz antennas.

      Ericsson RRUS82 2.5 GHz 8T8R
      Now being found in Ericsson vendor territory, these augment the existing Nokia Flexi 2.5 8T8R radios in place.

      Ericsson RRUS31 B25 + RRUS11 B26
      These are the newest and greatest remote radio units to come from Ericsson. 

      The new Ericsson RRUS31  B25 should be fairly distinctive compared to the earlier RRUS11s and now the RRUS12s being deployed by ATT and Verizon. One of these new RRUS31s can do the job of two earlier RRUS11s thus reducing deployment costs for Sprint and complexity in deploying new sites and making it easier for users to spot as there are now 4 jumpers coming out of one RRUS31 rather than two from each RRUS11 that Ericsson originally deployed. 

      All future deployments will be utilizing the new Ericsson RRUS31s. In addition Ericsson are sending crews to their original deployments and swapping out older RRUS11s for these new RRUS31s due to the aforementioned fact that one RRUS31 can do the job of 2 RRUS11s. Weight savings will be significant at sites where there are 4 or 5 RRUS11 B25s that can be replaced by one or 2 RRUS31s. The Ericsson RRUS31 deployment project is known as the 65 Mhz Project.

      Note the additional antenna + PCS radio.
      Previously Ericsson utilized additional PCS radios and used RF combiners for high capacity setups where they utilized three or more PCS radios. This new setup will utilize a completey new antenna + radio set just like Samsung and run 4x2 MIMO on the LTE antenna / radio set.

      This type of setup is no longer deployed or utilized in new sites. Existing sites will be slowly converted to newer RRUS31 B25 via the Sprint 65 mhz project.

      Hey guys I found another newsletter about Sprint and Cox. I'll be posting the article here.

    • I started working on the Raspberry Pi 3b Plus tonight with an Sierra Wireless em7565. This one has all those cool features that I was describing up top. Not bad for ~39 bucks. I was waiting for a few open source firmwares to get through the compilebot6k's toobs; this one is built now. Some use modem manager or openWRT for the router side. This LTE radio is band(s) 2/26/41 capable on the Sprint side. Band 25 did not make the cut, but was on previous Sierra builds. This is a tester radio so there is a slight chance it will appear down the road. It has just about every other LTE band.  

      This is an example of the debug screen. GMO is nearest so we only get 26 from a far site. No 41 in our zip yet. 
      The best part is I can plug an MC7455(that would be Modem#2) or another EM7565 in and it can hop over to that or I can direct load balancing. I just wanted to show the EM7565 authenticated below. Another shot of my terrible reception. Here it is out of the armor.

      So, we have a stable software image. I will get it built and add some GPS features, then test on band 41 in Myrtle where present. We have one site w 8t8r gear to test 3xCA on, so it might be a minute. I am in 2xCA MM areas through the week. I will see how it likes the Magic box too. 

      I should have a true GB ethernet router to massacre in the next couple of weeks with software images already set to go. I can embed the radio beyond a USB adapter. It still requires m.2>mPCIe but that is one less failure point and better throughput. This was a great breakthrough in affordable and small solutions for us.  I have to go to bed and then work now.

      Have a great week everyone.
    • Thank you so much for bringing light to this! I would have never known about it had you not posted it! You've saved me a lot of money and lowered my bill moving forward! It wasn't an easy process, but well worth it. Unlocking the phones was surprisingly easy. But the small hiccup came with my final bill. When I received it, I thought I was screwed when I saw that the ETF was included. I almost paid for it too, but the frugal in me decided to call Sprint (couldn't hurt, right?). After an hour on the phone with a US supervisor, my account was credited for the full amount of the ETFs. I walked away Scot-free!! Thanks a bunch OP! I'm trying Verizon's throttled unlimited data plan. Excellent reliability in the city, but there are certain key spots where I need my phone that aren't great. I don't know if it's the throttling or the network.
    • I see more mass upgrades by TMO on 600mhz -- it seems they did an amazing and fast roll out. If I recall folks here thougt TMO wouldn't be able to see much strides for a year plus.

      Reason I bring it up is TMO can't have much more free cash than Sprint. Yet can operate fast and lean.

      Positive note Sprint has rocked it's upgrades this past year...
