Is WiMAX or LTE the better 4G choice? - 0 views

  •  
    WiMAX (worldwide interoperability for microwave access) is a fourth-generation (4G) telecommunications technology primarily for fast broadband. Also a 4G mobile technology, LTE allows a peak download speed of 100 megabits per second (Mbps) on mobile phones, compared with 20Mbps for 3G and 40Mbps for WiMAX. "For operators, the choice of technology depends on a number of things including available spectrum, legacy inter-working, timing and business focus," says Nokia Siemens Networks head of sub region, Asia South, Lars Biese. To deploy either technology, operators will have to commit tens of billions of dollars in network upgrades for the new mobility landscape, which now includes social, video, location-based and entertainment applications and experiences. Wing K. Lee says WiMAX and LTE more similiar than different. Also a 4G mobile technology, LTE allows a peak download speed of 100 megabits per second (Mbps) on mobile phones, compared with 20Mbps for 3G and 40Mbps for WiMAX. Some argue that LTE is the next step for mobile networks like GSM, WCDMA/HSPA and CDMA in the move to future networks and services. The common belief is that the natural migration path is from 2G to GPRS, from GPRS to 3G, and from 3G to LTE. But IDC Asia/Pacific's telecom research director Bill Rojas has a differing view. To him, LTE is a totally new set-up. It has been reported that LTE's main advantage over WiMAX, in addition to speed, is that it is part of the popular GSM technology and can allow backward compatibility with both 2G and 3G networks. A point many dispute.  The new Sprint EVO is a 4G smartphone with chipsets for 2G, 3G, 3G enhanced, and 4G WiMAX.  Sprint argues that LTE is just another chipset away.

LTE vs WiMAX - Comparing both 4G mobile broadband standards - 0 views

  •  
    Excellent comparison of WiMAX and LTE.  The chart provided is exceptional. The future of the US mobile broadband market is taking shape right before our very eyes, with both the LTE and WiMAX flavors of 4G wireless data networks promising to deliver the internet to your mobile phone at speeds that might give your home broadband connection a case of "bandwidth envy." But, with heavyweights behind both the LTE and WiMAX 4G technologies battling it out for mind share (that's you, silly), it can be confusing to figure out which side of the great wireless Internet divide you should be sitting. That's where IntoMobile comes in. This is where we break down the pros and cons of each technology to help you decide whether or not to go with WiMAX now or wait for LTE in the near future.

USA, USA, USA: America's 4G Network Is Ranked 62nd 'Best' In The World (Behind Macedoni... - 0 views

  • The United States takes pride in being a technological leader in the world. Companies such as Apple, Alphabet, IBM, Amazon and Microsoft have shaped our (digital) lives for many years and there is little indication of that changing anytime soon. But, as Statista's Felix Richter notes, when it comes to IT infrastructure however, the U.S. is lagging behind the world’s best (and many of its not-so-best), be it in terms of home broadband or wireless broadband speeds. According to OpenSignal's latest State of LTE report, the average 4G download speed in the United States was 16.31 Mbps in Q4 2017.

  • That’s little more than a third of the speed that mobile device users in Singapore enjoy and ranks the U.S. at a disappointing 62nd place in the global ranking.
  • While U.S. mobile networks appear to lack in speed, they are on par with the best in terms of 4G availability. According to OpenSignal's findings, LTE was available to U.S. smartphone users 90 percent of the time, putting the United States in fifth place.

Long-Secret Stingray Manuals Detail How Police Can Spy on Phones - 0 views

  • Harris Corp.’s Stingray surveillance device has been one of the most closely guarded secrets in law enforcement for more than 15 years. The company and its police clients across the United States have fought to keep information about the mobile phone-monitoring boxes from the public against which they are used. The Intercept has obtained several Harris instruction manuals spanning roughly 200 pages and meticulously detailing how to create a cellular surveillance dragnet. Harris has fought to keep its surveillance equipment, which carries price tags in the low six figures, hidden from both privacy activists and the general public, arguing that information about the gear could help criminals. Accordingly, an older Stingray manual released under the Freedom of Information Act to news website TheBlot.com last year was almost completely redacted. So too have law enforcement agencies at every level, across the country, evaded almost all attempts to learn how and why these extremely powerful tools are being used — though court battles have made it clear Stingrays are often deployed without any warrant. The San Bernardino Sheriff’s Department alone has snooped via Stingray, sans warrant, over 300 times.
  • The documents described and linked below, instruction manuals for the software used by Stingray operators, were provided to The Intercept as part of a larger cache believed to have originated with the Florida Department of Law Enforcement. Two of them contain a “distribution warning” saying they contain “Proprietary Information and the release of this document and the information contained herein is prohibited to the fullest extent allowable by law.”  Although “Stingray” has become a catch-all name for devices of its kind, often referred to as “IMSI catchers,” the manuals include instructions for a range of other Harris surveillance boxes, including the Hailstorm, ArrowHead, AmberJack, and KingFish. They make clear the capability of those devices and the Stingray II to spy on cellphones by, at minimum, tracking their connection to the simulated tower, information about their location, and certain “over the air” electronic messages sent to and from them. Wessler added that parts of the manuals make specific reference to permanently storing this data, something that American law enforcement has denied doing in the past.
  • One piece of Windows software used to control Harris’s spy boxes, software that appears to be sold under the name “Gemini,” allows police to track phones across 2G, 3G, and LTE networks. Another Harris app, “iDen Controller,” provides a litany of fine-grained options for tracking phones. A law enforcement agent using these pieces of software along with Harris hardware could not only track a large number of phones as they moved throughout a city but could also apply nicknames to certain phones to keep track of them in the future. The manual describing how to operate iDEN, the lengthiest document of the four at 156 pages, uses an example of a target (called a “subscriber”) tagged alternately as Green Boy and Green Ben:

  • In order to maintain an uninterrupted connection to a target’s phone, the Harris software also offers the option of intentionally degrading (or “redirecting”) someone’s phone onto an inferior network, for example, knocking a connection from LTE to 2G:
  • A video of the Gemini software installed on a personal computer, obtained by The Intercept and embedded below, provides not only an extensive demonstration of the app but also underlines how accessible the mass surveillance code can be: Installing a complete warrantless surveillance suite is no more complicated than installing Skype. Indeed, software such as Photoshop or Microsoft Office, which require a registration key or some other proof of ownership, are more strictly controlled by their makers than software designed for cellular interception.

iPhone 5 Review - CNET Reviews - 0 views

  •  
    "The good: ......... The iPhone 5 adds everything we wanted in the iPhone 4S: 4G LTE, a longer, larger screen, free turn-by-turn navigation, and a faster A6 processor. Plus, its top-to-bottom redesign is sharp, slim, and feather-light. The bad: ............ Apple Maps feels unfinished and buggy; Sprint and Verizon models can't use voice and data simultaneously. The smaller connector renders current accessories unusable without an adapter. There's no NFC, and the screen size pales in comparison to jumbo Android models. The bottom line: .............. The iPhone 5 completely rebuilds the iPhone on a framework of new features and design, addressing its major previous shortcomings. It's absolutely the best iPhone to date, and it easily secures its place in the top tier of the smartphone universe."

Why the next iPhone should be on Sprint | DVICE - 0 views

  •  
    Excellent discussion of CDMA based 3G, Sprint WiMAX 4G, and Verizon's VERY limited capacity GSM LTE.  Keep in mind that Verizon is today an exclusive CDMA+ shop.  They do not do GSM (AT&T, Apple and most of the rest of the world outside the USA).  No mention of T-Mobile who has introduced a very fast and thick CDMA+ that is faster than WiMAX. excerpt: I'm hoping Apple expands beyond AT&T with Sprint instead of Verizon or, at least does what Samsung just did with the Galaxy S series - make an iPhone for all the major carriers. Why should iPhone be on Sprint? Here's five reasons:

In Mobile, Fragmentation is Forever. Deal With It. - washingtonpost.com - 0 views

  •  
    I disagree with the authors conclusions here.  He misses some very significant developments.  Particularly around Google, WebKit, and WebKit-HTML5. For instance, there is this article out today; "Google Really is Giving Away Free Nexus One and Droid Handsets to Developers".  Also, Palm is working on a WiMAX/WiFi version of their WebOS (WebKit) smartphone for Sprint.  Sprint and ClearWire are pushing forward with a very aggressive WiMAX rollout in the USA.  San Francisco should go on line this year!   One of the more interesting things about the Sprint WiMAX plan is that they have a set fee of $69.00 per month that covers EVERYTHING; cellphone, WiMAX Web browsing, video, and data connectivity, texting (SMS) and VOIP.  Major Sprint competitors, Verizon, AT&T and TMobile charge $69 per month, but it only covers cellphone access.  Everything else is extra adn also at low speed/ low bandwidth.  3G at best.  WiMAX however is a 4G screamer.  It's also an open standard.  (Verizon FIOS and LTE are comparable and said to be coming soon, but they are proprietary technologies).   The Cable guys are itneresting in that they are major backers of WiMAX, but also have a bandwidth explosive technology called Docsis. There is an interesting article at TechCrunch, "In Mobile, Fragmentation is Forever. Deal With It."  I disagree entirely with the authors conclusion.  WebKit is capable of providing a universal HTML5 application developers layer for mobile and desktop browser computing.  It's supported by Apple, Google, Palm (WebOS), Nokia, RiMM (Blackberry) and others to such an extent that 85% of all smartphones shipped this year will either ship with WebKit or, an Opera browser compatible with the WebKit HTML5 document layout/rendering model.   I would even go as far as to say that WebKit-HTML5 owns the Web's document model and application layer for the future.  Excepting for Silverlight, which features the OOXML document model with over 500 million desktop develop

CPU Wars - Intel to Play Fab for an ARM Chipmaker: Understanding What the Altera Deal M... - 0 views

  • Intel wants x86 to conquer all computing spaces -- including mobile -- and is trying to leverage its process lead to make that happen.  However, it's been slowed by a lack of inclusion of 4G cellular modems on-die and difficulties adapting to the mobile market's low component prices.  ARM, meanwhile, wants a piece of the PC and server markets, but has received a lukewarm response from consumers due to software compatibility concerns. The disappointing sales of (x86) tablet products using Microsoft Corp.'s (MSFT) Windows 8 and the flop of Windows RT (ARM) product in general somewhat unexpectedly had the net result of being a driver to maintain the status quo, allowing neither company to gain much ground.  For Intel, its partnership with Microsoft (the historic "Wintel" combo) has damaged its mobile efforts, as Windows 8 flopped in the tablet market.  Likewise ARM's efforts to score PC market share were stifled by the flop of Windows RT, which led to OEMs killing off ARM-based laptops and convertibles.
  • Both companies seem to have learned their lesson and are migrating away from Windows towards other platforms -- in ARM's case Chromebooks, and in Intel's case Android tablets/smartphones. But suffice it to say, ARM Holdings and Intel are still very much bitter enemies from a sales perspective.
  • III. Profit vs. Risk -- Understanding the Modern CPU Food Chain
  • ...16 more annotations...
  • Whether it's tablets or PCs, the processor is still one of the most expensive components onboard.  Aside from the discrete GPU -- if a device has one -- the CPU has the greatest earning potential for a large company like Intel because the CPU is the most complex component. Other components like the power supply or memory tend to either be lower margin or have more competitors.  The display, memory, and storage components are all sensitive to process, but see profit split between different parties (e.g. the company who makes the DRAM chips and the company who sells the stick of DRAM) and are primarily dependent on process technology. CPUs and GPUs remain the toughest product to make, as it's not enough to simply have the best process, you must also have the best architecture and the best optimization of that architecture for the space you're competing in. There's essentially five points of potential profit on the processor food chain: [CPU] Fabrication [CPU] Architecture design [CPU] Optimization OEM OS platform Of these, the fabrication/OS point is the most profitable (but is dependent on the number of OEM adopters).  The second most profitable niche is optimization (which again is dependent on OEM adopter market share), followed by OEM markups.  In terms of expense, fabrication and operating system designs requires the greatest capital investment and the highest risk.
  • In terms of difficulty/risk, the fabrication and operating system are the most difficult/risky points.  Hence in terms of combined risk, cost, and profitability the ranking of which points are "best" is arguably: Optimization Architecture design OS platfrom OEM Fabrication ...with the fabrication point being last largely because it's so high risk. In other words, the last thing Intel wants is to settle into a niche of playing fabs for everybody else's product, as that's an unsound approach.  If you can't keep up in terms of chip design, you typically spin off your fabs and opt for a different architecture direction -- just look at Advanced Micro Devices, Inc.'s (AMD) spinoff of GlobalFoundries and upcoming ARM product to see that.
  • IV. Top Firms' Role on That Food Chain
  • Apple has seen unbelievable profits due to this fundamental premise.  It controls the two most desirable points on the food chain -- OS and optimization -- while sharing some profit with its architecture designer (ARM Holdings) and a bit with the fabricator (Samsung Electronics Comp., Ltd. (KSC:005930)).  By choosing to play operating system maker, too, it adds to its profits, but also its risk.  Note that nearly every other first-party exclusive smartphone platform has failed or is about to fail (i.e. BlackBerry, Ltd. (TSE:BB) and the now-dead Palm).
  • Intel controls points 1, 2, and 5, currently, on the food chain.  Compared to Apple, Intel's points of control offer less risk, but also slightly less profitability. Its architecture control may be at risk, but even so, it's currently the top in its most risky/expensive point of control (fabrication), where as Apple's most risky/expensive point of control (OS development) is much less of a clear leader (as Android has surpassed Apple in market share).  Hence Apple might be a better short-term investment, but Intel certainly appears a better long-term investment.
  • Samsung is another top company in terms of market dominance and profit.  It occupies points 1, 3, 4, and 5 -- sometimes.  Sometimes Samsung's devices use third-party optimization firms like Qualcomm Inc. (QCOM) and NVIDIA Corp. (NVDA), which hurts profitability by removing one of the most profitable roles.  But Samsung makes up for this by being one of the largest and most successful third party manufacturers.
  • Microsoft enjoys a lot of profit due to its OS dominance, as does Google Inc. (GOOG); but both companies are limited in controlling only one point which they monetize in different ways (Microsoft by direct sales; Google by giving away OS product for free in return for web services market share and by proxy search advertising revenue).
  • Qualcomm and NVIDIA are also quite profitable operating solely as optimizers, as is ARM Holdings who serves as architecture maker to Qualcomm, NVIDIA, Apple, and Samsung.
  • V. Four Scenarios in the x86 vs. ARM Competition
  • Scenario one is that x86 proves dominant in the mobile space, assuming a comparable process.
  • A second scenario is that x86 and ARM are roughly tied, assuming a comparable process.
  • A third scenario is that x86 is inferior to ARM at a comparable process, but comparable or superior to ARM when the x86 chip is built using a superior process.  From the benchmarks I've seen to date, I personally believe this is most likely.
  • A fourth scenario is that x86 is so drastically inferior to ARM architecturally that a process lead by Intel can't make up for it.
  • This is perhaps the most interesting scenario, in the sense of thinking of how Intel would react, if not overly likely.  If Intel were faced with this scenario, I believe Intel would simply bite the bullet and start making ARM chips, leveraging its process lead to become the dominant ARM chipmaker.  To make up for the revenue it lost, paying licensing fees to ARM Holdings, it could focus its efforts in the OS space (it's Tizen Linux OS project with Samsung hints at that).  Or it could look to make up for lost revenue by expanding its production of other basic process-sensitive components (e.g. DRAM).  I think this would be Intel's best and most likely option in this scenario.
  • VI. Why Intel is Unlikely to Play Fab For ARM Chipmakers (Even if ARM is Better)
  • From Intel's point of view, there is an entrenched, but declining market for x86 chips because of Windows, and Intel will continue to support Atom chips (which will be required to run Windows 8 tablets), but growth on desktops will come from 64 bit desktop/server class non-Windows ARM devices - Chromebooks, Android laptops, possibly Apple's desktop products as well given they are going 64 bit ARM for their future iPhones. Even Windows has been trying to transition (unsuccessfully) to ARM. Again, the Windows server market is tied to x86, but Linux and FreeBSD servers will run on ARM as well, and ARM will take a chunk out of the server market when a decent 64bit ARM server chip is available as a result.
  •  
    Excellent article explaining the CPU war for the future of computing, as Intel and ARM square off.  Intel's x86 architecture dominates the era of client/server computing, with their famed WinTel alliance monopolizing desktop, notebook and server implementations.  But Microsoft was a no show with the merging mobile computing market, and now ARM is in position transition from their mobile dominance to challenge the desktop -notebook - server markets.   WinTel lost their shot at the mobile computing market, and now their legacy platforms are in play.  Good article!!! Well worth the read time  ................

Rural America and the 5G Digital Divide. Telecoms Expanding Their "Toxic Infrastructure... - 0 views

  • While there is considerable telecom hubris regarding the 5G rollout and increasing speculation that the next generation of wireless is not yet ready for Prime Time, the industry continues to make promises to Rural America that it has no intention of fulfilling. Decades-long promises to deliver digital Utopia to rural America by T-Mobile, Verizon and AT&T have never materialized.  
  • In 2017, the USDA reported that 29% of American farms had no internet access. The FCC says that 14 million rural Americans and 1.2 million Americans living on tribal lands do not have 4G LTE on their phones, and that 30 million rural residents do not have broadband service compared to 2% of urban residents.  It’s beginning to sound like a Third World country. Despite an FCC $4.5 billion annual subsidy to carriers to provide broadband service in rural areas, the FCC reports that ‘over 24 million Americans do not have access to high-speed internet service, the bulk of them in rural area”while a  Microsoft Study found that  “162 million people across the US do not have internet service at broadband speeds.” At the same time, only three cable companies have access to 70% of the market in a sweetheart deal to hike rates as they avoid competition and the FCC looks the other way.  The FCC believes that it would cost $40 billion to bring broadband access to 98% of the country with expansion in rural America even more expensive.  While the FCC has pledged a $2 billion, ten year plan to identify rural wireless locations, only 4 million rural American businesses and homes will be targeted, a mere drop in the bucket. Which brings us to rural mapping: Since the advent of the digital age, there have been no accurate maps identifying where broadband service is available in rural America and where it is not available.  The FCC has a long history of promulgating unreliable and unverified carrier-provided numbers as the Commission has repeatedly ‘bungled efforts to produce accurate broadband maps” that would have facilitated rural coverage. During the Senate Commerce Committee hearing on April 10th regarding broadband mapping, critical testimony questioned whether the FCC and/or the telecom industry have either the commitment or the proficiency to provide 5G to rural America.  Members of the Committee shared concerns that 5G might put rural America further behind the curve so as to never catch up with the rest of the country
