  1. Your EV (3G) must've been dormant or idle (no data transfer) for your MAC index to be 0; otherwise, it looks decent (for Sprint).

    Your 1x on the other hand--- you're either at the edge of the sector or you're getting alot of carrier pollution from too many nearby sectors for the Ec/Io to go that low-- it's not good when it drops below -8 dB or so. There may just be alot of users on that sector right now.

     

    I turned on Navigation and Dropbox sync to generate some data traffic. I set the Field Test refresh rate to 1 sec. MAC never changed and State stayed at inactive. What's up wit dat?

  2. If you're running HTC Sense ROM, dial ##DEBUG# (##33284#), you don't have to press call. You'll be able to see 1x and EVDO channels under their respective engineering screens along with the sector ID and PN (pseudo-random noise code). More importantly, you'll see the EVDO SNR or Ec/Io ratio and the MAC index, which tells you how many concurrent users are on your sector.

    Nokia Siemens Networks, who isn’t exactly a market leader in terms of the amount of revenues involved in the mobile infrastructure game, is widely respected as being a leader when it comes to research and development. They just

    demonstrated a 1.4 gigabit per second connection using LTE-Advanced and 100 MHz worth of spectrum. As impressive as that figure sounds, we need to put it into some perspective. Eight months ago, to the day, we filed a report about Ericsson’s LTE-Advanced demo. They used 60 MHz worth of spectrum and were able to hit over 950 Mbps in a moving van. So that’s 60% of the spectrum NSN used, yet 68% as fast as NSN’s test, which by the way was done in a laboratory under perfect conditions. Can you see why Ericsson gets all the contracts? Just last week they announced their own “industry first”, they were able to triple the upload speed of HSPA using just software.

     

    Anyway, the bigger question is when are we going to see LTE-Advanced networks in the wild? If you believe Dish Network,

    then it’s going to happen next year in the United States. Though to be perfectly honest, we don’t think LTE-Advanced will really take off until 2014 or so. Even then, operators don’t have 100 MHz worth of spectrum to throw at a network. Verizon’s 4G LTE network, arguably the biggest and baddest 4G LTE network in the world, uses two 10 MHz channels in several markets. They’d like to use more spectrum, and they’re currently trying to buy some more, but they’re rightfully getting some push back from T-Mobile who wants the market to remain competitive.

     

    So long story short: NSN wrote a fantastic press release that’s going to get a lot of coverage, yet at the same time the technology is several years away. Assuming LTE-Advanced went live right now, what the hell are you going to do with a 1.4 gigabit per second in your smartphone anyway?

  4. One other thing that is killer in BR: the stupid low-e glass they use downtown now-- damn treehuggers! I had jury duty down there-- and you could tell the half dozen Sprint users were lined up along the wall so they could get half a bar of signal from the tower less than 2 blocks away! The energy saving crap kills all the PCS signal! The AT&T and Verizon guys were just sitting in their chairs playing away on their phones and I was standing by the window leaning on the window with my tongue hanging half out trying to get my mouth right to catch a signal-- and I know I was killing the EVDO on that sector trying to pull timeslices.

     

    Why would Verizon work but Sprint would not. Both are on 1900 MHz, aren't they?

  5. A post in another forum asked:

     

     

    I really don't get Sprint continuing to "support" an independent "Clear" when they already own ~ 50% of the company. Google is selling it at a loss, $1.60 a share and Sprint should snap up every share at that price if they can. The debt is already on the books, just pay it off as Sprint and take the 2.5Ghz spectrum back under Sprint control.

     

    Giving Clear another 600 Million is throwing good money after bad. Buy up the rest of the company now, and put 2.5 Ghz in all of the Network Vision towers.

     

    So why wouldn't Sprint purchase Clear? Liabilities?

    Freescale Semiconductor has succeeded in cramming an entire cellular base station onto a single chip. It’s a claim many chipmakers have made, but other “base-station-on-a-chip” designs have focused primarily on small cells and femtos. But at Mobile World Congress on Monday, Freescale revealed it has reduced the baseband capacity of a big honking tower-based macrocell to a system-on-a-chip (SoC) design.

     

    That’s not only an impressive feat of miniaturization and integration, it could kick off the next-generation of LTE deployments, lower the costs of building mobile networks and reduce the energy required to run them. When all those factors are taken into account, base station SoCs could cut the cost of delivering a bit of data, which ultimately could lead to cheaper mobile data plans for the consumer.

     

    The brains of a base station typically reside in a channel card, a sort of hopped up motherboard designed to perform the extremely complex task of encoding and decoding of radio signals. Usually wireless infrastructure vendors like Ericsson and Alcatel-Lucent design those channel cards as a bunch of discrete components: digital signal processors, applications processors, and a variety of hardware accelerators. The new QorIQ Qonverge design stamps all of those discrete components onto a single piece of silicon.

     

    So why is this significant? SoCs are much cheaper to manufacture than the sum cost of all of those separate components, and also drain far less power. According to Scott Aylor, director and GM of Freescale’s wireless access division, a single QorIQ chip can support the capacity of a three-sector 20 MHz LTE cell site – the same configurations Verizon and AT&T are using in their new 4G networks – for one quarter of the cost. Aylor also said the highly integrated platform also drains three times less power, which will help operators design more energy-efficient networks. If operators can build cheaper networks and cut their operating costs they could theoretically offer mobile broadband at cheaper prices.

     

    That performance and power efficiency will make QorIQ a building block for future network technologies such as LTE-Advanced, Aylor said. LTE-Advanced will require enormous processing resources as the bandwidth pumped out by each cell grows well beyond 100 Mbps. “We’re well ahead of the LTE-Advanced curve,” Aylor said.

     

    Furthermore, Freescale customers like Alcatel-Lucent and Nokia Siemens Networks are already exploring a radical shift in network design. Known as cloud radio access network, or cloud-RAN, it seeks to divorce the base station from the cell site. Instead, operators could build signal-processing farms in a private cloud, in essence virtualizing their base stations. Whenever capacity is needed, cell sites – which be little more than radio heads at this point – would reach into the cloud and grab it. Again, Aylor said SoCs would be ideal for such a scenario.

     

    “We can build farms of 64 of these things on a single card, then daisy-chain them together,” Aylor said. “There’s not a significant limitation on our side as to how far we can scale.”

     

    Aylor said the key to developing the SoC was Freescale’s utilizing new 28-nanometer process technology, allowing it to condense a lot more performance in much less space. That means Freescale’s competitors can’t be far behind as most of them are already going down the 28-nm path.

     

    Digital signal processing giant Texas Instruments has already developed powerful SoCs for use in Cloud-RAN platforms and is using them to power smaller-sized cells. Aylor, however, said Freescale believes it has significant advantage over its competitors as it can supply a single-chip solution across the board, from the lowliest femtocell to the most powerful macrocell.

     

    Not all network vendors subscribe to the SoC approach, Aylor admits, but Fujitsu and Alcatel-Lucent are already converts. The Franco-American networking giant is already using QorIQ chips in its new lightRadio architecture, initially in its Cube small cells, but it plans to begin designing its macro base stations around the new SoCs as well.

  7. Oh-and I forgot to mention that since I'm on an Advantage Club plan (sponsored by an employee/friend who works at Sprint) I am not on a contract' date=' I can cancel at anytime even after I upgrade (although technically you're supposed to keep the line open for 60 days after upgrading, or at least that was the policy when I worked there).

    I'll proably make a final decision over the weekend :azn: [/quote']

    It is now 180 days.

  8. From Fierce Wireless

    Challenges facing wireless operators are exemplified in two different industry reports released this week, which separately reveal skyrocketing growth in mobile broadband traffic and a breakneck pace of network investment.

    Global mobile broadband traffic grew by 83 percent in the second half of 2011 with a CAGR of 234 percent during 2011, according to the latest global mobile broadband traffic report from mobile service optimization company Allot Communications.

     

    Video streaming traffic continued its phenomenal rise, with 88 percent growth in 2H11, and is now gobbling up a 42 percent share of all global bandwidth. YouTube accounts for 24 percent of global broadband traffic, and 14 percent of total YouTube traffic is now high-definition.

     

    Other services are also consuming increasing amounts of global mobile bandwidth. VoIP and IM traffic grew by 114 percent in 2H11, which Allot noted is "consistent with recent reports marking the decline of SMS and international voice calls."

     

    Mobile operators have made no secret of the fact that the challenges of meeting escalating demand for broadband data services is driving them to make heavy network investments and migrate to next-generation technologies such as LTE. Industry vendors are reaping the rewards of these substantial network investments.

     

    Dell'Oro Group announced that in 2011 the mobile radio access network (RAN) market recorded its strongest full-year revenue growth since 2004, with mobile RAN revenues growing 15 percentage points during 2011. Ericsson (NASDAQ:ERIC) and Huawei recorded the largest full-year 2011 revenue increases and maintained their No. 1 and No. 2 revenue share rankings, respectively, in the mobile RAN market.

     

    LTE RAN investments accounted for 40 percent of global mobile RAN growth in 2011. However, the strong momentum that drove the mobile infrastructure RAN market in 2011's first nine months slowed at year's end, paving the way for slower growth in 2012, the consultancy said.

     

    "While operators in North America maintained capex guidance for 2011 and front-end loaded investments were expected, it was the shift in product mix from capacity to LTE coverage that resulted in weaker than anticipated wireless infrastructure investments," commented Stefan Pongratz, mobile infrastructure analyst at Dell'Oro.

  9. I seem to remember that the big deal about wireless broadband was for the "last mile" problem. If you have wired broadband there really is no reason for it. It is an inferior technology. Now out in rural areas, it is a viable alternative to satellite. It is just too bad about the limit. But as long as it is not used for videos, 6 GB for 59.99 ain't bad considering the alternatives.

    Can the world’s richest corporation really not afford to build iPhones and iPads in the United States? ....Apple says no...

     

    Back in the 1980s, Apple was having trouble getting Japan to open its market to Apple products, and it wanted the U.S. trade negotiators’ help. At the time, Apple espoused “the funny notion that the U.S. government had an obligation to help them,” Prestowitz recalls. In the 1990s, when Apple was hurting, it sought tax breaks from the city of Cupertino and the state of California.

     

    Even now, the company gets help from the U.S. in the form of protection of its intellectual property from cloners in other countries. Apple and other U.S. firms often find their products being counterfeited overseas and ask the U.S. government to press other countries to crack down on the copycats. “Whenever some executive says, ‘I have a fiduciary responsibility to my shareholders and not to the U.S.,’ I say, ‘Well, OK, then don’t come to me when you have problems with theft of intellectual property,’” says Prestowitz, who now leads the Economic Strategy Institute.
