  1. by Jeff Foster 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. Sensational graphic extolling the dire spectrum crisis. Maybe a tad exaggerated???

  2. I just saw a news article that the United States government is investigating AT&T and Verizon for wireless collusion. I'm going to post a link below. Let's please keep this discussion on track. https://mobile.reuters.com/article/amp/idUSKBN1HR2Z8
  3. Yikes! T-Mobile shouldn't have spoken so soon about deploying 5G nationwide before VZW and AT&T. It'll only be a dozen cities by year end but nonetheless, I wouldn't be surprised if AT&T fast-tracked this roll out just to spite T-Mobile. I'm expecting a similar announcement from VZW very soon. Source: AT&T announces plans to start rolling out a true 5G network by the end of 2018
  4. Hate to bring up another carrier on here, but I am on AT&T right now and do plan to switch to sprint as soon as my contract is up. is there a forum similar to this but relating to the AT&T network?
  5. 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?

    Verizon's Coverage Comparison

    Am I the only one that likes to look at Verizon's coverage comparison tool. I think it gives a good idea of a carrier's generalized coverage as far as those cities that have been announced. However, it takes a while for it to get updated. I look at Verizon's map and think, no one will ever build an LTE network of that size. When I look at T-Mobile, I see a spotty, spread out network. AT&T is also spotty with a few highways covered here and there. Sprint seems to be more put together as in even if it is spotty, they are in blobs rather than random remote areas. I've also found a few places that Sprint has coverage in but not Verizon such as in southern Texas. http://www.verizonwireless.com/wcms/consumer/4g-lte.html
  7. The next step in shutting down former Alltel in Georgia is underway: http://www.phonescoop.com/articles/article.php?a=15007 Of note, AT&T's commitment to keep CDMA live in these markets expires June 15, 2015; I'd be surprised if they keep it on a day longer, which means a fallback to 1x on Verizon for Sprint customers roaming off the interstates and a few other corridors in south Georgia. The SouthernLINC RRPP buildout can't come soon enough...

    AT&T Launching VoLTE

    AT&T took the plunge. Let's see how far they can go with it and how it compares to the HD Voice offerings of Sprint and T-Mobile. [url="http://www.androidcentral.com/att-switches-hd-voice-small-test-markets-small-phone
  9. Now all your WCS are belong to AT&T...
  10. It's official: Google Fiber is coming to Austin. AT&T has also said that, provided they get the same incentives that Google does, they'll run gigabit as well. I trust AT&T about as far as I can throw one of their VRADs, but we'll see what happens between now and when Google connects its first customer, over a year from now.
  11. AT&T's LTE network impaired by salon's fluorescent light By Tammy Parker AT&T's (NYSE:T) cellular network has faced myriad challenges over the years, such as the overwhelming capacity crunch that hit when Apple's (NASDAQ:AAPL) first iPhone rolled out. But the latest threat to AT&T's network is particularly illuminating, because the problem is being caused by a common fluorescent light fixture. The fixture is located inside the Perfect Cuts Salon in a San Antonio, Texas, strip mall. By simply flicking the salon's lights on and off...
  12. "This is pretty incredible when you think about it: Verizon has instituted a system where I actually have incentives to not use its network." http://bgr.com/2013/09/27/verizon-att-lte-data-cap-criticism/
  13. Via FierceWireless: In their quest for more spectrum, this will be the fourth acquisition of a facilities-based carrier by AT&T this year, following Alltel (ATN), Leap, and Iowa's Long Lines. Given that they are shutting down the CDMA network, I hope they are not a Sprint roaming partner. I'm having trouble finding a coverage map for them.
  14. From GigaOM: Interesting excerpt from the AT&T public policy blog post: Details are thin on what that "software feature" is, or how it works to remove Ch. 51- 700 MHz B-block interference that the smaller carriers deny is even present. Also, if it's true that AT&T has been investing "considerable time" in modifying it's 700 MHz LTE equipment, you'd think they'd have tipped off Google (Nexus 5) or Apple (iPhone 5C/S) about that. Still, this seems like a step in the right direction toward LTE roaming, or at least a step away from further industry consolidation. Telecompetitor also has some nice maps that give an overview of where the major players own A and B block spectrum, and make the good point that after the upcoming 600 MHz incentive auctions, DTV Channel 51 will be the first to be cleared, rendering the A block interference controversy moot, and Band 17 entirely redundant. Perhaps that is why AT&T is making this move now.

  16. "So you could argue that SoftBank’s ability to smack down bigger rivals like NTT-DoCoMo and KDDI did not hinge on the one-time surprise attack it staged in 2007. SoftBank has been able to keep its bigger rivals on the defensive through half a decade, introducing a variety of new pricing and marketing strategies." "If SoftBank does acquire Sprint (S) and/or Clearwire (CLWR), the obvious U.S. analogs to NTT-DoCoMo would be AT&T (T) and Verizon (VZ)." http://www.bgr.com/2012/10/12/softbank-sprint-acquisition-analysis/
  17. So as you cruise the internet at work and things are getting you down, just think you could be working at the Car Wash.
  18. AT&T is making it known that it is going to try to capitalize on Sprint's iDEN shutdown over the next year. http://www.att.com/gen/press-room?pid=22974&cdvn=news&newsarticleid=34695&mapcode=consumer|enterprise AJ
  19. I've seen various times around the site that Verizon's 700 Mhz LTE site spacing is rather large and they don't have it deployed on all the towers they have EVDO, whereas Sprint is going to deploy 800 Mhz LTE on most (I think I've seen 85%?) of their sites. Meaning for in-building coverage Sprint would have a better set-up. Has AT&T done the same thing as Verizon and used the fact that 700 has a large range and deployed it to just achieve coverage? I haven't really seen a lot of mention of AT&T's LTE on this site and was curious how Sprint's 800 Mhz will likely compare to theirs once completed in an area.
  20. Came across a book on the History of Bell Labs. Jon Gertner's The Idea Factory, was an interesting read. Interesting to see how Bell Labs conceived the future, which is now the present. Book goes into the development of transistors, solar cells, RADAR, microwave communications, information theory, satellites, UNIX, CCDs, LASERs, lightguides and the list goes on and on. http://www.nytimes.com/2012/04/08/books/review/the-idea-factory-by-jon-gertner.html?pagewanted=all&_r=0 I had no idea how involved in the defense industry Ma Bell was with Sandia.

  22. I have a question, outside of the data issue, Why is it that people refuse to be on sprint? I have seen people talk bad about Sprint more than T-Mobile.

    AIO Wireless DIscussion

    Making this thread for discussion about the new AT&T MVNO Aio Wireless. Curious to see what anybody has to say that's tried them. What kind of speeds you get (also pings), coverage (especially in larger buildings), and whatever else. Had a response from a person in another thread who said they got longer pings (100-200 ms) than normal for AT&T LTE (attributed it to a Aio proxy) so if anybody else has seen the same it would be interesting to know. Also if anyone has used both Aio (or AT&T) and Sprint LTE and can provide some comparison that'd be cool especially since this is a Sprint forum. Also any comments about AT&T's network (HSPA+, LTE, 2G) would be great.
  24. Came across this website today that compares customer complaints to all carriers and locations. You will learn that every company has issues and significant ones. It will also help those people who want to switch carriers to see what reviews the other companies got. I learned sprint in NYC is rated 2nd and of all four carriers and every carrier has dead zones. (Not a lot of reviews on site but sill some interesting info) Check it out and add any thoughts. http://www.cellreception.com/coverage/ Click on your city at the bottom of page..or put zip but i learned clicking on city works better. I recommend adding your review and spreading awareness as well.
  25. While commuting to work this morning on MetroNorth, the railroad put a copy of their monthly newsletter on all the seats. Interestingly enough, they officially stated that cell service is coming to the Park Avenue tunnel. This tunnel is the main artery between Grand Central and the outdoor world, and all MetroNorth trains travel through it. Interestingly enough, the big carriers have contracted Ericsson to provide the cell coverage throughout the tunnel and public WiFi in the terminal. AT&T, Sprint, T-mobile, and Verizon are all funding the project and it will take up to two years to complete. This announcement will soon be posted on MTA.info under the MetroNorth Mileposts section, but I was able to find an earlier report here: http://gothamist.com...g_to_grand.php Will this be a good thing for commuters or will it turn out to be annoying with people screaming "I'm in the tunnel can you hear me?" into their phones? Only time will tell!
