Everything 800mhz (1xA, LTE, coverage, timeline, etc)

Recommended Posts

 

Thanks for clearing it up. I hope Sprint does near 100% 800 CDMA and LTE for NYC and LA as well . I think NYC especially as a city being mostly urban with thick buildings, I think its important to be able to get a signal indoors so hopefully 100% of 800 CDMA and LTE.

 

In a place like NYC, that's a great example of where Sprint will skip a lot of sites. Unless they need the capacity. Does it matter if your CDMA 800 or LTE 800 signal comes from one block or three? No. The difference in signal will be negligible.

For places like NYC, what is considered 'close' together cell cites? Are they closer than 1000 ft sometimes?

In Manhattan there is a tower roughly ever 3 blocks. In Midtown Manhattan they have cell sites virtually ever other block. In Brooklyn ibthink every 5 blocks or so. Tower spacing is crazy in NYC.

In Brooklyn and Queens, 1,000 feet separation is probably average. In Manhattan, it's much tighter.

And that site density is necessary because those New Yawkers are stacked so many on top of each other like the dead in a mausoleum.

In places like where I live in ohio, where cell sites are much further apart, I would think they would deploy 800 LTE on every site, unless they add more sites, which I don't think will happen.

I had no idea that the sites were that close here.

How big is a block?

 

Oh man that's hard to tell... I think the standard block size [pictured below] is 1.5x2.5x7.5cm in dimensions.

The standard Manhattan Block is about 264 feet by 900 feet.

Sprint is deploying roughly 80% 800MHz for budget reasons. They think it's a waste of money to deploy on 100% of sites with 800 as it is more than capable to serve two PCS cells in many urban places. And they will go back and fill in 800 in these 20% when and if extra capacity is needed. So the goal is 100% 800 coverage in urban areas, but not 100% sites having it.

 

It's not an interference issue, as they can downtilt and reduce power to mitigate interference in most instances.

 

In some places they are deploying near 100%. Like in Chicago. They desperately need the capacity there. And in other markets, more 800 can be added for capacity as needed.

Since our market is under construction I'll say that 9/10 towers I pass that have upgrades are equipped with 4 rru's per antenna. I can only think of about 3/30 that have 3 or less rru's per antenna.

They may not actually use all of the RRU's.

 

As I understand it, licensing is a much larger cost than the physical hardware so they can add several RRU's initially and only use two. They save money on the additional LTE license by not using them until they need the capacity.

Yes, I just mean that they are installing all 4 up front so that when they are ready they can turn them on without re climbing the tower.

The additional RRU is actually for the cdma side of things right now. If the site needs more than 4 carriers for evdo/1x then a second rru is installed with an RF combiner to connect the 2 RRUs to the one side of the antenna.

It was explained to me that on a full build site each antenna holds RRU's 1900 1x & Lte,800 1x & Lte. Most upgraded towers I have seen have all 4 on each antenna panel. I have seen a few with 3 rru's and i swear i saw one the other day and as long as i looked up all i could see was that it has 1 rru @ several wires coming in from the southwest facing sector; I'm not sure if its a splice or what i couldn't make out all the work that had been done up there at the time.

 

Back to the licensing, I've yet to see any 800 MHZ 1X......and i'm counting down the days till i do. I miss the reliability of the Macro network. My airave 2.0 has been losing gps lock since i put it in this house. Worked fine in my old home last year;I guess i should just move the gps beacon outside.

LTE 800 can be run on the same RRU as CDMA 800. If you see a 4th RRU, it usually means the site has more than four CDMA carriers. Each RRU can handle up to 4 carriers.

 

In the case of the 800 RRU, it is running only one CDMA 800 carrier and eventually one LTE 800 carrier. They tend to leave LTE 1900 on its own RRU in Ericsson markets. So that is two of the four. The other two are CDMA 1900, for a combination of 1x and EVDO.

Thank you for clearing that up Robert, i had got a rundown one afternoon while talking to a site crew member when they were assembling the antenna on the ground; albeit his english was not to good, and my 3 years of Spanish are a little rusty. Lo siento mi amigos.

This is the PCS channel that several months ago I alerted folks in Fort Wayne to be on the lookout for...

 

The problem with that is that Sprint does not hold the PCS F block license in Fort Wayne. But I did find a new bit of info. Sprint has started leasing the lower 5 MHz of the PCS E block from AT&T. So, Fort Wayne is no longer stuck at only 10 MHz -- the worst of the top 100 markets. Sprint in Fort Wayne is now working with 15 MHz, which has allowed it to deploy one additional carrier, probably EV-DO.

To tack on a quick addendum to my post above, members in the Fort Wayne area should be on the lookout for the PCS 0725 carrier channel assignment (to go along with the existing PCS 0325, 350, 375 assignments).

      IBEZ will be solved SOONER, rather than later.
       
      Which is a good thing. I would have liked for SoftBank to join the fight, because EVERYONE knows that their roaming rates are going to be abysmal with Sprint customers traveling to Mexico.
       
      Is this a raw deal? Your thoughts?

      The closest Sprint tower to my house is about 3.5 miles away. In between are hills, trees, a handful of houses, and fields. However, I do have line of sight. I can see the blinking light of the tower in the distance at night. I do not think Sprint has deployed any LTE at this tower. When they do, is it possible that the LTE signal would reach my house?
       
      Right now I have a Moto X, but I may go back to the Q10. I do pick up eHRPD at my house. What frequency is that on? I'm thinking Sprint's 800ish mhz LTE band might. Not sure about 1900 though..
       
      Thanks

      With the extremely fast ramp-up of band 26 deployment in the recent months, a lot of the US is now covered by it. Some markets have been optimized, some haven't. 
       
      For those markets that have seen band 26 optimization, what's your story? Did you used to get a weak 3G connection indoors, and now enjoy a usable 1-2 bar LTE connection? 
       
      Is your 800Mhz LTE connection stronger, the same, or slightly weaker than 3G now? 
       
      Let's try to keep this focused only on stories about areas that have seen a definite coverage improvement as a result of a fully optimized band 26 LTE deployment, not a thread that focuses on where optimization hasn't taken place yet. Perhaps we can boost morale and give us non-optimized folks something to look forward to. :-)

      I'm James from OpenSignal. We're trying to map international rollout of LTE, but very few phones can report the band and bandwidth used, so we're hoping people can help us by firing up field test mode and submitting the data to our map - all the data can be downloaded.
       
      We've already got a great map of South Korea and China, there's a lot of 10 MHz and 20 MHz bands there, which explains why they're clocking some of the fastest LTE speeds on the planet.
       
      You actually need to use "service mode" on Android to do this: 
      Type
      *#0011#
      Into a dialer. 
       
      You should see
       
       

       
       
      Here you can read the LTE stats easily. The Band is 7 (around 2600 MHz), and the LTE Bandwidth for download (LTE DL BW) is 15 MHz. Actually the Earfcn_dl gives a more precise reading of the band, 2825, so if this available use this.
       
       
      You can fill in the form here: Google docs form
      Your data will appear on a map here: LTE bandwidth map.
       
      This won't work for all Android phones, I'm yet to find any other codes that can bring up this info (field test modes & service modes are implemented differently on different devices.  
       
      On iOS try:
      *3001#12345#*[/size]
       
       
      Btw if any admin has the permissions, you can embed the form and map right here:
      Form:
      If that works fill out this form and your information will be automatically mapped:
      Loading…
      All the information is public, and responses are mapped immediately below – you will probably need to refresh this page before your data becomes visible. If it doesn’t appear after that there may be a problem geocoding please email me James (@ opensignal.com) with your observation and we’ll get it up.

    • Another beta update to SignalCheck Pro is rolling out! Version 4.614b will appear on Google Play sometime over the next several hours. More 5G improvements, the accent color should be fixed, and several Samsung shortcut menus were added. Samsung users, please try all of the new shortcuts and let me know which ones are useful and what they lead to. Thank you!
    • No, unfortunately I haven't seen any useful 5G info from your phone (or anyone else's LG) yet. If you get a software update and happen to find 5G before they shut it down, please try reporting again! The accent color is still in its infancy and only appears on LTE for now. I've had it on my version of SCP for several weeks, initially I didn't think anyone else would like it. Figured I'd offer it up and see what the feedback was.
    • I accidentally broke the Samsung menus when I compiled the latest release; it will be resolved in next update.   Thanks, I'll look into that.. it's all a work in progress, glad we are making some headway!   The current display format is temporary, it is just to get the data displaying reliably.. once that happens, it will get its own "block" like the connection other technologies have.
    • I forgot to post this this morning. Seems that Sprint will offer the V60. My buddy at Sprint HQ says more will be said Monday. Lets see if this pans out.   TS out
    • Another suggestion, can you place the 5G info above the neighbor cell list? In dense urban areas with 5x CA there will easily be enough neighbor cells to push the 5G info off the screen. Sent from my SM-G988U using Tapatalk
