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.

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.

 

I was just thinking the same thing...Can't wait to see some pics in the wild!

Has Any one seen any of these Yet in the wild, or permits for the Locations these are going?

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.

    • I've now seen how things work in Kobe, Hiroshima, and Osaka, as well as some areas south of Osaka (e.g. Wakayama, Kinokawa), and tried three more SIMs. The two physical SIMs (different branding for each) both use IIJ, which provides a Japanese IP address/routing on NTT, aleit LTE-only, so latency is ~45ms to Tokyo. The catch with NTT is that it uses two frequency bands (B42/3500 MHz LTE, n79/4900 MHz NR) that you're not going to get on an Android sold in the US, and I'm guessing that B42 would be helpful speed-wise on that network, as it doesn't have B41. I also found one place that doesn't have cell service: a vending machine in the back of the Osaka Castle tower. Or, rather, the B8/18/19 signal is weak enough there to be unusable. Going back to 5G for a moment, I saw a fair amount of Softbank n257 in Hiroshima, as well as in some train stations between Osaka and Kobe. 4x100 MHz bandwidth, anchored by B1/3/8, with speeds sometimes exceeding 400 Mbps on the US Mobile roaming eSIM. Not quite the speeds I've seen on mmW in the States, but I've probably been on mmW for more time over the past few days than I have in the US over the past year, so I'll take it. My fastest speed test was actually on SoftBank n77 though, with 100 MHz of that plus 10x10 B8 hitting ~700 Mbps down and ~80 Mbps up with ~100ms latency...on the roaming eSIM...on the 4th floor of the hotel near Shin-Kobe station. Guessing B8 was a DAS or small cell based on signal levels, and the n77 might have been (or was just a less-used sector of the site serving the train station). I'm now 99% sure that all three providers are running DSS on band 28, and I've seen 10x10 on similar frequencies from both NTT and SoftBank IIRC, on both LTE and 5G. I also picked up one more eSIM: my1010, which is different from 1010/csl used by US Mobile's eSIM unfortunately, as it's LTE-only. On the bright side, it's cheap (10GB/7 days is like $11, and 20GB for the same period would be around $15), and can use both KDDI and SoftBank LTE. It also egresses from Taiwan (Chunghwa Telecom), though latency isn't really any better than the Singapore based eSIMs. Tomorrow will include the most rural part of our journey, so we'll see how networks hold up there, and from tomorrow night on we'll be in Tokyo, so any further reports after that will be Tokyo-centric.
    • I think the push for them is adding US Mobile as a MVNO with a priority data plan.  Ultimately, making people more aware of priority would allow them (and other carriers) to differentiate themselves from MVNOs like Consumer Cellular that advertise the same coverage. n77 has dramatically reduced the need for priority service at Verizon where the mere functioning of your phone was in jeopardy a couple of years ago if you had a low priority plan like Red Pocket. Only have heard of problems with T-Mobile in parts of Los Angeles. AT&T fell in between. All had issues at large concerts and festivals, or sporting events if your carrier has no on-site rights. Edit: Dishes native 5g network has different issues: not enough sites, limited bandwidth. Higher priority would help a few. Truth is they can push phones to AT&T or T-Mobile.
    • Tracfone AT&T sims went from QCI 8 to 9 as well a couple years ago. I'm pretty neutral towards AT&T's turbo feature here, the only bad taste left was for those who had unadvertised QCI 7 a couple months ago moved down to 8. In my eyes it would have been a lot better for AT&T to include turbo in those Premium/Elite plans for free to keep them at QCI 7, while also introducing this turbo add on option for any other plans or devices. As it stands now only a handful of plans can add it, and only if you're using a device on a random list of devices AT&T considers to be 5G smartphones.
    • My Red Pocket AT&T GSMA account was dropped to QCI 9 about a year ago.  Most recently 8 for the last few years prior.  Voice remains at 5.
