Does anyone know why Sprint didn't pick Nokia Siemens?

NSN did not have a CDMA version of their new Flexi, which T-mobile is utilizing, at that point and time which precluded them from participating in the bids.

How do I become a sponsor ???

Sprints maximum is like 30-35mbps down & 10-15up I want that to be regular consistently . I like to strea video & people say you only 5-10mbps well yeah you need 5-10mbps go stream the video but for it to be clear & not stop & constantly buffer ur gonna need something more than 10mbps , & tbh I expected better from Sprint with the whole upgrade speed wise . I understand the NYC market is VERY crowded but other carriers such as AT&T & Verizon (mainly ATT) manage to pull off high speeds ATT average 20mbps , their peak is something like 55-60 (thats overkill in my opinion) , T-Mobile is similar , Verizon is just overly packed so every once in a while they'll reach that otherwise their LTE is slower than Sprint's -_- .

First off. You need to read up a bit more before you start complaining about speeds.Sprints 5x5 has a maximum theoretical output of 37.5mbps DL and ~ 14 mbps UL. The theoretical maximum is the absolute maximum that is physically allowed in our known universe with regards to scientific laws in an absolute perfect setting. Sure, getting 30-35 mbps is nice but that requires a near perfect line of sight to the cell site in addition to zero entity other than you utilizing that specific sector. An entirely non realistic feat that no carrier can ever provide and is the main reason all the major carriers advertise speeds in the ballpark of 5-10 mbps.

Second. It's not all about the "5-10mbps vs 20-30mbps" that matters most in streaming video. Although streaming video and data intensive usages does have a minimum requirement, once we hit the ~6mbps range, there isn't much one cannot do with that connection. What matters most is the ping time which severely affects the human perception of "slow" or "fast".

Ping time is the delay one gets after inputting a command via touch to query a response from an online server. As I'm a semi-active / former hardcore PC gamer, ping time is a major aspect that should never be overlooked. The lower the ping (sub 150 ms) is better as everything feels more "responsive" due to the fact that queries sent to the server and coming back is done in a fraction of a second. On the other hand, once you get to the 200ms ping time, you start noticing something widely known as "lag" where everything is less responsive due to the fact that the queries sent to the server and back are much slower than every other persons connection. It means that you may be shooting at an enemy on your screen but in reality already got killed 150 ms before but it has not registered on your end yet due to the connection being slower.

This is one of the main reasons that gamers and other data intensive users prefer sub 100 ms ping and one of the main reasons sprints network vision requirement for backhaul is sub-100 ms ping for LTE. A 5-10 mbps connection with ~40ms ping will feel far "faster" than a 15-25 mbps connection with ~150-200 ping [cough cough] due to this alone.

Third. Carriers such as Verizon Wireless and ATT Mobility use 10x10mhz chunks of spectrum for their LTE deployment which has theoretical maximums of something like ~70 mbps DL and ~20 mbps UL. A 10x10 channel will always provide more bandwith available for users thanks to its wider radio waves. It's simple math really. 20mhz > 10 mhz.

Sprints counter though is carrier aggregation and small cell deployment which should significantly help in highly densely locations like NYC. Carrier Aggregation (CA) is a LTE-Rel 10 (LTE-A) technology that combines two separate blocks of spectrum and utilizes them as one like how DC-HSPA works. I'm sure someone can explain it better but in essence CA will allow Sprint to maintain their network speeds for a while to come as they can easily shut down a 5x5 chunk utilized for EVDO and CA it with the other PCS 5x5 chunk used for LTE and provide double the capacity (?).

TLDR: sub 100ms ping + 5-10 mbps DL speeds = much faster response than 20-30 mbps DL speeds & > 150ms ping due to the fact that communication between device and targeted server is done faster.

Will the 800 CDMA/LTE be added if an agreement can be made with Mexico? Yuma is out of luck if not as we are like less than 10 miles from the border.

Yes but that will be at a minimum of many months if not years away.

Anyways , you guys have been finding new towers how are the speeds ?

On average for me i've gotten 10-15mbps not consistent either , I was hoping that would improve .

Question do you guys think that once the market is fully rolled out & completed that the speeds will improve ?

If an adjacent and closer site went online then probably OOverall? No. It will go down to around 5-10mbs on average as more and more users start utilizing the service.

Thanks for response. Im in sprint 3g area. Aren't they supposed to cover their existing footprint?

Yes. Most, if not all Sprint cell sites will get NV upgrades of some sort be it full build sites or GMO's. Clearwire sites are not operated by sprint but by clearwire who is doing their own thing until they get bought out by Sprint.

I think I in one of these protection sites. Will I receive NV lte? My location is Huntington Wv.

No.

So basically, lilotimz has unofficially been designated your 'Mini Me'?

uh oh.. "looks at my username... inspired by Lilo and stitch*

Hmm, When they deinstall everything, could some of the locations get replaced with NV?

Potentially but only 100 or so towers to our knowledge are confirmed to do so. Remember, these would be full site replacements and can costs hundreds of thousands of dollars each. It's something that Sprint will probably look into once Softbank takes over and starts pouring billions into New Sprint.

NV1.0= complete physical replacement of sprints legacy network. New modular gear will be installed including modular base stations, multi band and remote controlable antennas that support 800/1900 and upgraded backhaul.

NV2.0= activation of SMR 800 service on a wide deployment on both CDmA and LTE. In addition, Clearwire TDd-LTE sites will be utilizing 2500 mhz for hotspot offloading in huge 20mhz carrier aggregated channels. This is beginning with the Nextel iden shutdown on June 30,2013 11:59:00pm

So with Samsung towers being installed, does that mean HTC phones will not get LTE?

That statement is just wrong on so many levels but to sum it up... it does not matter who makes the telecom gear as long as it broadcasts the correct signals that the device you have was designed for. If a device was made for Sprints frequencies than it will search for those frequencies. Radio waves don't discriminate against certain cellular devices... (looks at Gnex & 1x)...

TLDR: NO. 1900mhz A-> G blocks = 1900 mhz A-> G blocks. If that signal is being broadcast ed then your phone will receive it.

So what would actually be involved in deploying EV-DO Rev. B on NV sites? Is it just a software update or would there be more to it? If its something that wouldn't require significant resources, why not do it? Even on a single channel config you'd get benefits from it on the network side and the end user would get slightly faster speeds.

 

If its a significant cost then of course don't do it, but if its fairly straightforward then what's the harm?

Spectrum and the fact that Sprint wants people off the EVDO network onto the LTE network so they can use the spectrum for PCS and aggregate it for LTE.

Intriguing for sure. Excited to see how this turns out. Doesnt the FCC usually make a stink about foreign corps buying out US communications infrastructure?

*Looks at deutsche telekom & Vodafone*

what is IBEZ?

International Boundary Exclusion Zone.

Areas where sprint cannot deploy SMR 800 service due to interference issues with foreign government / private entities. Canadian border will be all PCS 1900 for the foreseeable future due to their safety band being on SMR and they're getting PCS only panels in response. The southern border is being worked out but it'll still be years before they can deploy down there.

So each panel, 1 per side has approx 120 degrees of coverage?

Depends. Some are 120, others are 90, some 65, and narrow band ones are either 30 or 45 degrees.

Apparently they begun applications a while ago in the UCV (I've only been checking Sacramento permits) as I've now found quite a few permit applications in other cities dating from mid to late march. Most excellent finding this is... most excellent... :evil:

.....NV 3.0!

Actually it's NV 2.0... the mass deployment of SMR 800 services (LTE and CDMA 1xA) and utilization of TDD-LTE 2500-2600 as hotspots in major urban areas where capacity is needed.

So I get terrible service at my house, the average is a about -100 dBm (barely can hold a call)

 

1. I wanted to know how lte would be like for me

2. Will my signal get better in about 9 months (I live in Houston )

3. How much of an Improvement would it make once my tower is upgraded.

4. Is 800 MHz coming soon

1. It Will be excellent. I believe Houston is one of Sprints remaining markets which has a spectrum crunch on PCS (20mhz overall iirc) and the deployment of SMR 800 LTE & CDMA 1xA V will help out substantially.

2. Yep, SMR 800.

3. Oh.. that'll depends. Expect anywhere from up to 4-10 dB in improvement or even significantly better if you get connected to SMR 800.

4. Yep. It's being deploy sparsely on CDMA 1xA V in many markets and is slated to quickly come into service after Nextel iDen is shut down on june 30,2013. All currently deployed Sprint NV hardware is capable of immediately broadcasting SMR 800 with minor work being done. The problem is that the Nextel iDen network is still running and you can't utilize the SMR 800 frequency till you shut it down.

My lucky day if it was. haha

Thanks for the tips, I'll cruise around this week and hunt them down.

 

 

I wonder.. since samsung is doing the hardware, will their devices have a small edge on others?

Samsung Telecommunications=/= Samsung electronics

Reception is all about your phones design and the SGS3 is an excellent RF performer.

aaagghh... I was hoping to have LTE in time for my birthday, but I guess I can settle for a bunch of beers and them maybe starting LTE

 

I'm going to check Lodi/stockton's sites for those permits, and if not I can at least stop by Stockton's since I work downtown.. the place I need to go can't be far from here. Where would I need to go to get them? There's a ton of county building on this block but idk where to start. I'll gladly share any info I find, unless someone's already done some digging

 

Best bet is to look around City of [insert name] website and then looking at building permits. Usually cities will have an archive of who applied for what and you can find it from there. If they don't then you'll need to find out which department handles building permits and check for their main office location - aka call to confirm.

From what I recall... there was one city which was giving Sprint / Samsung headaches regarding permits but I do not recall if it was stockton.

How do you find this stuff? haha. Are the timelines mentioned earlier accurate then?

 

Thanks for the tip, I'll have to come up with an excuse to head to midtown soon

 

I've started to notice more and more cell towers as I drive around... I've even gone out of my way several times to get a closer look at them. Pretty interesting tech up there.

No timelines other than the excellent repository of knowledge that robert provides and my own combing through city websites for permit information. Some cities post them online (in case of most major cities in CA) while other smaller towns needs to be done in person. Given that LCV is also getting permit applications around this time, i'll venture to say that Samsung is starting both markets right now and will be in full swing by june / july. Just in time for iDen's shut down... :]

Other than that, the standard turnaround from application date to issue date is approx 3 weeks from what I see of T-mobile modernization applications so work should begin around the end of May, give or take 2-3 weeks, if all goes well.

Applications for building permits related to network vision has begun in sacramento, CA. It's begun!!!!!

I think I'll head by shabu japanese fondue or shoki ramen II house in a few weeks... "cough cough"

Why is the nv upgrade giving us better coverage? To me it makes no sense. Better antenas?

You'er a sponsor and have access to a wealth of information pertaining to NV. Use it as this question has been asked many a times before and answered.

To people that haven't seen it.. basically the answer for improved coverage at the edges of cell service is the fact that the new antennas are much more efficient than the legacy panels in addition to the fact that RRU's are mounted extremely close to them. This allows the new setups to get as much as up to 20% better performance than the old ones which translates somwhere to the 5-10 dB range. This minor increase can mean the difference between usable service at the extreme edge of a cell site or no service / crappy service & can be sometimes viewed as increased coverage.

I just hope they implement some 800mhz love in Puerto rico. If the system is smart I would assume it would only give the user that lower frequency when needed.

No 800mhz in PR anytime soon as have been stated again and again.

Wow those are rather narrow channels, I suppose all things considered its rather impressive they move so much data on such thin swaths of spectrum. Also isn't Nextel's iDEN literally going to be shut down officially in like a month, I seem to remember June/July 2013?

Yes. ~14 mhz across most of the nation except for certain areas in the southeast where Solinco is not sharing the spectrum with sprint. In that area, Sprint has to utilize a 3x3 setup for LTE in addition to a different channel for CDMA 1xA. Rest of the nation, except for the exclusion zones around the borders, will have just enough spectrum for one 5x5 LTE setup alongside a CDMA 1xA V setup in addition to the guard bands.
