    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.

Republic-Wireless

  • Do I need to buy minutes from Sprint or anyone else? No. We're the first-ever wireless provider to bundle WiFi calling with access to cellular whenever you need it. Depending on the plan you choose, your Republic Wireless phone will have unlimited* access to data, talk and text when using the Sprint cellular network. Note that the $5 plan offered by Republic is WiFi only and the $10 plan includes cellular talk and text (no data). All Republic plans include unlimited data, talk and text on WiFi. 
  • Can I switch between plans? Yes! When you purchase a new Moto X phone, you’ll be able to choose whatever plan you like—and you can also switch plans up to twice per month as your needs change. For example, if you know you’ll be taking a vacation and might require more cell data one week, you can switch to a cell data plan right from your phone and then switch back to a WiFi “friendlier” plan once you return home.

    Republic Wireless provides a new kind of smartphone cellular service based on a technology that handles the roll over from WiFi to 3G or 4G cellular in the middle of a call. Very cool, but currently it only works with specially outfitted (custom ROM) Android Moto X phones. (They are working on how to port this custom ROM technology to all Android phones :) The concept is based on the fact that WiFi is cheap, very open and near universally available; while 3G and 4G Cellular is expensive, contractual and proprietary. The idea is to leverage free WiFi wherever they can, and roll over to the Sprint 3G - 4G network when needed. Very cool and the business model seems to have it right. ......................................................................... "Which Moto X plan is right for me? Here's the lowdown on our four new plan options. Depending on your needs and how you want to use your phone, you can choose the plan that's best for you. $5 WiFi only plan This is the most powerful tool in your arsenal of options. Why? You can drop your smartphone bill-at will-to $5. If you're interested in getting serious about cutting costs, you can use this tool to best leverage the WiFi in your life to reduce your phone bill. It's also the ultimate plan for home base stickers and kids who don't need a cellular plan. It's fully unlimited data, talk and text-on WiFi only. $10 WiFi + Cell Talk & Text One of our members, 10thdoctor said :  "I use WiFi for everything, except when I'm traveling and for voice at my school." Yep, this is the perfect plan for that. Our members are around WiFi about 90% of the time. During that 10% of the time where you're away from WiFi, this plan gives you cellular backup for communicating when you need to. This plan both cuts costs and accommodates what's quickly becoming the norm: a day filled with WiFi. $25 WiFi + Cell (3G) Talk, Text & Data Lots of people are on 3G plans today and are paying upwards of $100 a month on

How to Jailbreak iOS 4.0 for iPhone 3G - 0 views

    Jailbreaking vs. Unlocking Jailbreaking and unlocking the iPhone are two different hacks which allow you to take control of your mobile device in different ways. Jailbreaking is a type of hack that lets you install unapproved third-party applications on your iPhone or iPod Touch from searchable repositories provided by apps like Cydia and Icy. Unlocking, on the other hand, is a hack that lets you use your iPhone on another cellular network. Here in the U.S., that means you can use the iPhone on T-Mobile instead of AT&T. You have to first jailbreak your phone before you can unlock it, but you don't have to unlock a phone in order to jailbreak it. How to Jailbreak the 4.0 Software for the iPhone 3G and iPod Touch Second Generation The "Redsn0w" jailbreak software has been updated to support iOS 4.0 on both Mac and Windows and works for iPhone 3G and the iPod Touch, second generation. This jailbreak is especially helpful for for iPhone 3G owners as the new OS won't offer the much sought-after multitasking feature on their devices. A jailbreak application called multifl0w will, however, provide an alternative. Another jailbreak app called WinterBoard offers a way to customize the iPhone's background even though that too is disabled for 3G owners running the latest OS 4.0 update. This jailbreak guide assumes you've already downloaded and updated your phone or iPod Touch to the latest software, iOS 4.0, and have backed up your device. If you are looking to unlock your phone in order to run it on a network belonging to another carrier, this is not the guide for you.

    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:

    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

    Web 2.0 2009 presentation is loaded with charts and numbers, all of which point to an explosive growth in mobile access to the Internet.  Lots of 3G projections.  Nothing on 4G though.  This years Web 2.0 will no doubt be all about 4G and LTE, Apple, and Google Android/Chrome

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

surveillance state Stingray documentation

shared by Paul Merrell on 15 Sep 16 - No Cached
  • 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:
  • ...2 more annotations...
  • 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.
