I just noticed that eHRPD is back on in San Jose today. Also, the tower close to Santana Row has been broadcasting 800Mhz all week and now it looks like LTE as well. Hopefully things are picking up steam in this part of the market

Look what popped out of the ground the other day, could the recent rain we had have led to this? y2edynuv.jpg

Seems like the old water tower may no longer be the sprint cell site. Can't wait for it to be completed. This is in Gonzales, CA.

What is that?  It looks like a doppler radar site.

This is what it is. Although this picture is a bit old as well. If you guys want up an updated picture, I can get one. Right now that water tower looks crazy. Has a giant scaffold and being repainted.

Will let you know later today, when I'm in the north part of San Jose.  What device are you using, and where are you trying to catch the signal?  I'm curious as to what practical effect the new 800 CDMA signal will have on my day to day use.

No 800 on my drive to work or at work.  I've been on band 25 the whole time.  I'm on an iPhone 5s and am in an area where 99% of the towers are now 800 CMDA accepted.  Based on info in the map updates thread, it seems I'll get 800 only when there's no 1900 available...

I believe that iPhones prefer 1900 (if available) over 800.  Other phones simply prefer either 800 or 1900 depending on what they're currently / last connected to.

You're right.  Getting CDMA 800 on an iPhone in an urban area is tough to impossible.

Doesn't help for me...though I do get a weak 1900 signal so it must take zero (or close) 1900 signal to have the phone switch to 800.  I don't care which I'm using but with all the talk about 800 making things better indoors, it's a bummer that I'm not seeing it.

On an iPhone, it will not begin to scan 1900 until you completely lose a 1900 signal and then rescans all the 1900 channels to make sure there is no 1900 available.  After a 1900 rescan, it will then scan 800.  It is pretty hard to get CDMA 800 on an iPhone.

Does the iphone have similar behavior for LTE800?  Or is it network controlled?

Robert,

 

Thanks for the response.  Does this mean that iPhone users will benefit from 800 only when in areas with truly no 1900 coverage such as more rural areas or very deep inside a building (so basically we will roam less)?  It sounds as if 800 won't even help iPhone users with dropped calls, if the phone won't look for 800 until 1900 is completely lost.  Is there some other benefit for iPhone users that I'm missing?

PRL's only control scan behavior for CDMA.  For LTE it is network controlled regardless of device type.  We have already had a member in Wisconsin report being able to connect to Band 26 on an iPhone even while they were within Band 25 coverage.

Yes, this pretty much sums it up.  An iPhone user will get the benefit of 800 when they go outside of 1900 coverage.  However, once an iPhone gets on CDMA 800, it would likely stay there until it loses an 800 signal, the device is rebooted, airplane mode is cycled or the PRL is updated.

Well....That's just annoying. At least LTE is network controlled so Ill be able to get data inside. Most of my friends have iPhones so I can always just make a FaceTime audio call if I have crappy voice. Thanks for the insight... This seems to be  a very big question that a lot of people are asking, including me. Maybe it should be an article? OR is it already?

I don't think it's really just a choice by Sprint.  In my mind, it is either a device problem and they are working on a software solution for it.  Or Apple has requested that 800 be a low priority until 800 is more prevalent.  So the user experience is not hindered.  It is actually better to be on a cohesive 1900 network than a patchy 800 network.  It may change in the future.

Anyone else having a complete outage in North San Jose? I toggled airplane mode on and off, and my phone is getting no service.  This isn't looking good either:

When you say it's better to be on a cohesive 1900 network than a patchy 800 network, does that mean that the phone can't easily hand off between 1900 and 800 so it's not the same as any tower hand off?  In that case, I see the point.  If not (i.e., if the phone can hand off between 1900 and 800 interchangeably), then why not just make them the same priority?  Anyway, it will be interesting to see what happens with this.  Given Sprint's investment, and given how many subscribers use iPhones, I would think they will also invest in the software solution (if it's a device issue) or push Apple (if that's the issue) or come to their senses (if they're the ones programming the PRL in this manner).

A handoff between 800 and 1900 is technically possible if both networks are tied together at the same MSC cohesively.  But even in an ideal network set up, it is still a hard handoff and will have a much higher call drop rate than handing off between cells in the same CDMA band class.

 

Up until the 3G network is complete on all sites, both 1900 and 800, I don't think we will see a satisfactory handoff scenario between bands.  And this could be a driving factor with Apple.  Apple certainly doesn't want the perception that it is their device that is the problem.  And it's conceivable if someone moved from a Sprint 1900 only device and purchased a Sprint iPhone and then started dropping all over the place that they may conclude the problem is the iPhone since their previous device worked fine.

 

I don't know for fact, but I really feel Apple is the one that has pushed for iPhone PRL's to push CDMA 800 only as a last resort.  If I am right, then a new PRL will come out likely by Mid 2014 that will change the priority for CMDA 800 for iOS devices.

Thanks for the response.  Given the handoff issue, that makes sense.  And in this area, I go from the part of town where I live, where Sprint hasn't done much upgrading (many brown dots on the map and several white ones), to the part where I work (95% NV and 800 capable)...that would result in dropped calls (though I already get TONS in the first place).  Your suspicion would make sense for the South Bay market, which is where many of the Apple decision makers must live.

      I recently went on an 8 day cruise from NYC to the Caribbean that stopped in Turks and Caicos, Puerto Rico, and the Dominican Republic. My first stop was Grand Turk and there I opted for the free roaming. My S9+ automatically connected to Flow's (Cable & Wireless) LTE network where I received speeds of around 120kbps on average with boosts of up to 150kbps. Something worth noting is that on speed tests, the server prefers to default to Sprint's Miami server as opposed to local servers. Speeds were more than adequate for any amount of web browsing and honestly felt much faster than in reality. It helps that using Chrome will save you data by not loading pictures on certain sites unless you click them.
      In Puerto Rico, I connected to Band 13 on the way into the port in San Juan but once I was in the city, my phone never left Band 41. While the phone was usable, speeds remained significantly lower than what I've come to expect from 3xCA in the mainland U.S. Data speeds peaked at around 25-30Mbos but on average were in the 5-10 Mbps range even on LTE+. Signal remained strong everywhere though. 
      Finally in the Dominican Republic, I entered in Amber Cover which is in Puerto Plata. My phone latched onto a weak Band 2 LTE signal in the port from Altice (called Orange Dominicana in SignalCheck). I had trouble loading pages though. Once off of the ship and out in the open, I had a much stronger signal which allowed me to browse the internet without a hitch. Because it was the last day of my trip, while at the beach I decided to purchase the 24 hour high speed pass for $5. My speeds went from 120kbps to 65Mbps in less than 5 seconds. In some areas speeds were slower, particularly at the port where it struggled to break 2Mbps. Now, back on the boat my phone is flipping between weak Band 4 LTE and overloaded Band 5 HSPA+ from Claro (called Verizon Dominicana in SignalCheck Pro). Here is the difference in speed from before and after purchasing the high speed pass.

      Sprint 4G Rollout Updates
      Friday, April 20, 2012 - 11:31 AM MDT
       
      Is there a "spectrum shortage?" Those two words send shivers down the spines of wireless industry executives. New services demand ever more spectrum, and, the story goes, there simply isn't enough spectrum available. An Internet search engine will easily find hundreds of thousands of links to the term "spectrum shortage." Many claim that it will be the downfall of America.
      The dwindling availability of a finite resource that can't be seen or touched threatens to possibly disrupt the mobile lifestyle that virtually every American has embraced. Dropped cellphone calls, delayed text messages and choppy video streams could become more frequent occurrences because the airwaves on which that data travel are nearing capacity at a time when mobile usage shows no signs of slowing.
      Federal regulators and industry players are searching for ways to fend off the supply-and-demand collision. Dish Network recently acquired a large block of vacant wireless spectrum that pending regulatory approval could be used for mobile broadband services.
       
      Short-Term Plan

      AT&T tried to merge with T-Mobile to solve its own capacity problem. It wanted to get its hands on T-Mobile spectrum. Still, that would have been only a temporary fix at best. Remember all the terrible stories about the quality of AT&T's wireless data network over the last few years? They say they simply don't have enough.
      The reason is that during the last few years, smartphones like the Apple iPhone and the many devices running Android emerged, and wireless data traffic grew like crazy. This problem jumped up and bit AT&T in the rear end. Suddenly, so many people were sucking so much data that the network could not handle it, due to spectrum shortage. Spectrum is like the size of the hose, and a wider hose is needed to carry more data for more customers.
      A couple good things are suddenly happening that may give carriers a little time to solve this increasing problem. Perhaps Verizon starting to sell the iPhone last spring has something to do with it. If so, then now with Sprint selling the iPhone, AT&T will have more breathing room, at least temporarily. That's the good news. However, that reprieve will only last a short while before the exploding smartphone and wireless data growth catches up. Then the other carriers will be faced with the same problem that's confronting AT&T.
      In the first quarter of 2011, the amount of data the average smartphone user consumed each month grew by 89 percent to 435 megabytes from 230 MB during the same quarter in 2010, according to Nielsen research. That's up from about 90 MB in 2009. For reference, the average size of an MP3 music file is about 4 MB.
      "Texting has always been traditionally viewed as a lightweight consumer of bandwidth, but if I start adding videos and pictures to my texts, that also starts consuming more bandwidth," said Tom Cullen, an executive vice president with Dish. But the primary growth driver will be video. Consumers can go through 5 gigabytes a month simply by streaming 10 minutes of standard definition video daily, he said.
       
      Data use is skyrocketing
      Data from the FCC indicate that more Americans are looking at their phones rather than talking on them. In 2009, 67 percent of available spectrum was utilized for voice and 33 percent for Internet data. Those percentages are now at 75 percent for data and 25 percent for voice. With each new iPhone release, data consumption grows. The iPhone 4S eats up twice as much data as the iPhone 4 and three times as much as the iPhone 3G, according to a study by network services firm Arieso. The new iPhone features Siri, a bandwidth-heavy voice recognition feature.
      The FCC estimates the U.S. will face a spectrum deficit of 90 MHz in 2013 and 275 MHz in 2014. To address the crunch, the federal government hopes to unleash 500 MHz of spectrum currently used for other purposes for wireless broadband by 2020. To put that figure in perspective, there is currently 547 MHz of spectrum allocated for mobile services, and AT&T and Verizon each own about 90 MHz.
      The government plans to hold so-called incentive auctions, which will try to lure spectrum owners such as TV broadcasters to sell their licenses. Verizon Wireless has agreed to purchase spectrum from a group of cable-TV companies. Sprint has expressed interest in working with Dish, which acquired the bulk of its 45 MHz of spectrum through two deals for bankrupt satellite technology companies. Dish chairman Charlie Ergen has said that the satellite-TV provider would prefer to partner with an existing wireless carrier on a high speed, 4G network. In response to recent comments by Sprint Chief Financial Officer Joe Euteneuer about the company's interest in working with Dish, Cullen said other wireless carriers are in the same situation. After failing to acquire T-Mobile, analysts expect AT&T to make a play for Dish, a long-rumored merger partner.
      As for T-Mobile, perhaps the most logical buyer is CenturyLink. T-Mobile's German-based parent company has indicated that it might exit the U.S. market. CenturyLink, which acquired Denver-based Qwest last year, is the third-largest landline phone company but does not own a wireless service, unlike the top two, AT&T and Verizon.
      Carriers are trying to offload as much traffic as they can to Wi-Fi networks, which ride on unlicensed spectrum. In some areas, they're installing picocells, which are smaller cell sites that can help boost capacity in dense areas.
      Finally, they're spending billions of dollars on LTE networks that use the airwaves more efficiently. Verizon and AT&T already have 4G LTE networks in place, and Sprint is moving to the technology. Dish says it hopes to enter the mobile broadband market with advanced LTE technology by late 2014 or early 2015. If Dish were to also offer voice service, it would come through VoLTE, which is similar to Voice-over-Internet Protocol (VOIP) phone services. Dish still needs the FCC to drop a condition tied to its spectrum that requires devices to have the ability to communicate with satellites, not just ground-based cell sites. The rule-making process that will likely remove the requirement is underway and could be completed by summer's end.
       
      Is there really a shortage problem?
      The problem, analysts argue, is that the operators that control the greatest amount of unused spectrum may be under-capitalized or unwilling to build out networks to use the spectrum. "We do not believe the U.S. faces a spectrum shortage," Jason Bazinet and Michael Rollins wrote in their Citigroup report. "Too much spectrum is controlled by companies that are not planning on rolling out services or face business and financial challenges. And of the spectrum that is being used, 90 percent of it has been allocated to existing 2G, 3G, and 3.5G wireless services by larger wireless carriers, such as AT&T, Verizon Wireless, Sprint Nextel, and T-Mobile USA.
      In total, U.S. operators have licenses for about 538MHz of wireless spectrum. Only about 192MHz of that spectrum is currently being used. Most of the unused wireless spectrum is owned by companies such as Clearwire, LightSquared, and Dish Network. But so far, LightSquared has been stopped and the other companies have been slow to build networks using their available spectrum.
      "There is definitely a mismatch when it comes to spectrum in the wireless industry," said Paul Gallant, an analyst with MF Global in Washington, D.C. "There are some companies that have spectrum, but they're struggling financially. Or they aren't quite sure what to do with the spectrum. And others that have the money and business model, but need the spectrum." The move to 4G is very important for these operators because it offers them a more efficient way to deliver service. 4G LTE uses the available spectrum roughly 700 percent more efficiently than the 3G wireless technology EV-DO. Carriers will soon be refarming 3G spectrum to 4G LTE in several years.
      A key factor in encouraging efficient use of spectrum has been largely overlooked in carrier boardroom discussions. Wireless providers can add capacity, without obtaining more spectrum, by adding more and more cell sites. Additional cell sites in spectrum constrained areas allow the same spectrum to be used by even more consumers, as well as adding picocells and microcells to denser population areas. So far, the carriers have not expressed too much interest in this method due to additional capital expenditures and overhead. Their strategy is like what Microsoft, Apple and Google have used. It's just cheaper to buy what you need than to invest the time and energy to do the actual work.
      So what can the wireless companies do? To some extent, re-farming their existing networks will help. But so will finding ways to use other spectrum. For example, only T-Mobile lets users make phone calls using Wi-Fi, yet most of the mobile devices available from carriers have this capability; the carriers just don't enable it.
      Allowing Wi-Fi calling could unload millions of voice and data users on to alternative networks and ease the spectrum crunch, at least to some extent. Encouraging VoIP use would also help for two reasons. VoIP doesn't require a lot of bandwidth, and it means that the phone in question uses only the data spectrum, not both voice and data while this is going on.
      These points illustrate that the carriers do have options beyond just buying up spectrum. They can offload more wireless traffic than they do now, build more cell sites into their networks and they can allow the use of other types of communications. While the spectrum crunch isn't going away, that doesn't mean that the process can't be slowed.

      Sprint 4G Rollout Updates
      Tuesday, January 31, 2012 - 7:46 PM MST
       
      Since last fall, there had been talk of a Samsung Galaxy Nexus launching on American carriers other than Big Red. Sprint has finally announced several weeks ago that it is the another vendor slated for release in the U.S. Suffice to say, many of us out there, especially those adverse to heading to Verizon and paying its premium prices, are excited about the impending release.
      The good news is that Google could be working on an updated version of the Galaxy Nexus. It has unofficially been dubbed the Galaxy Nexus Plus. There is much anticipation that it will be released before Sprint turns on LTE this summer. It’s not the first time an OEM has refreshed a device and re-released it to the market place, which works to our advantage. It’s rumored that the new Galaxy Nexus will have either a 1.5 or 1.8 GHz Texas Instrument OMAP4670 dual core processor. This would be a significant upgrade from the 1.2 GHz dual core processor found in the current Verizon version.
      We don’t know anything about official specs, but it’s also rumored to have an 8 MP camera. This is a noteworthy upgrade to the 5 MP shooter on the Verizon model (which has been lauded by many techies). We already know that the Sprint model will come installed with Google Wallet, per previous announcements. Some rumors also point to a beefier battery as well. The phone should have all the other features that’s on the current Galaxy Nexus, so now all we have to do is wait.

      With Todays announcement that T-Mobile and Sprint are merging, and the announcement of the T-Mobile Sprint Roaming deal that will survive and will last for four years regardless if the merger is completed or not, which is effect immediately as stated in the conference call and the slides made available. So I thought I'd create this to see if anyone has been able to use their Sprint device on T-Mobile roaming yet. And of course if not, once you do, come back here and say you have. Personally I'm not bothering with anything until after the coverage map is updated again, hopefully to reflect the T-Mobile roaming. And of course if you are able to roam onto T-Mobile what kind of speeds are you pulling, and on what device.
      Also for those that are unaware, the T-Mobile Sprint Roaming agreement that was announced as part of todays merger announcement is a roaming agreement for Sprint customers to roam onto T-Mobile for 4 years and takes affect immediately, yes right now, regardless if the merger completes or not. Surely it's a stepping stone to integrating the networks by getting Sprint devices that are capable, which according to the conference call is 20 Million Sprint devices ready to be used on the T-Mobile network full time once deal is approved by the regulators and finally completed.

      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.

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.

      3 or 4 PCS RRUs are present for a total of 4 or 5 RRUS11s per antenna.
