Sprint to launch WiMax phone in 2010 that may run on Android

Filed under: Uncategorized — info @ 12:34 pm

February 12, 2009 (Computerworld) In early 2010, Sprint Nextel Corp. expects to launch a new smartphone that works over high-speed wireless WiMax, CDMA cellular and possibly Wi-Fi.

The actual form factor is “still being finalized,” said Scott Lane, director of marketing and sales for Sprint’s 4G unit, in an interview today.

Lane called the coming device a “trimode handset,” meaning it would function in three wireless modes. Including WiMax and CDMA, the third mode will most likely be Wi-Fi, although that piece has not been confirmed. “It will more than likely have Wi-Fi,” he added.

The WiMax portion could make the device the first stand-alone handset with WiMax capability. It will work over Clearwire Corp.‘s Clear WiMax network, which Sprint helped create last year in an ambitious joint venture with Clearwire, Intel Corp., Google Inc. and three cable companies.

The WiMax handset also “could be based on Android” partly because Sprint has a “close relationship with Google,” the main proponent of Android, Lane noted. Still, he said he would not commit to the operating system being based on Android because there are other operating systems that have the processing power to work with high-speed WiMax.

While Sprint spun off its WiMax initiative called Xohm in the joint venture with Clearwire, it has continued to run a 20-person unit devoted to WiMax product development and marketing strategy.

Regarding the Clear network being developed nationwide, Sprint will act as a Mobile Virtual Network Operator that uses the Clear infrastructure to transport data. But the WiMax products that Sprint sells, such as the coming handset, will be provisioned and supported by Sprint, Lane explained. In other words, customers would call Sprint for service calls.

In December, Sprint’s 4G unit announced a dual-mode air card for laptops in the Baltimore market that runs on WiMax and Sprint’s CDMA. While Sprint won’t disclose the number of sales of the air card, Lane said they are “on target.”

Sprint is also preparing to sell WiMax-related products in future Clear markets, which Lane said should reach 40 million to 50 million customers by the end of 2009.

In addition the current air card, which functions in both WiMax and CDMA networks, Sprint plans to offer an air card for laptops that functions only in WiMax. This card is mainly for users who don’t expect to move outside of a WiMax coverage area. It will be less expensive than the current dual-mode air card, which sells for $149 and requires an $80 monthly subscription to operate on both networks.

Also by the end of 2009, Sprint plans to introduce two WiMax modems, one for home users that rivals DSL or cable modem speeds, and the other for business users with higher speeds close to that of a T1 line, Lane said.

BlackBerry Storm – new Touchscreen phone

Filed under: Uncategorized — info @ 1:38 pm

Research in Motion’s all-touch-screen handset for Verizon and Vodafone supports EvDO rev. A in the United States and high-speed GSM networks overseas. But it’s definitely not an iPhone clone.

Research in Motion has finally announced details about its long-rumored iPhone competitor, an almost-all-touch-interface 3G handset with a twist: The screen itself is a big hardware button.

The ability to mechanically click the entire screen (RIM calls the feature Click-Through technology) is the centerpiece of the BlackBerry Storm’s touch interface. As with the iPhone, you can scroll and select by dragging and tapping with your fingertip. But to initiate action, instead of double-tapping, you confirm a selection by physically depressing or clicking the screen.

Four hardware buttons at the bottom offer additional–and traditional–BlackBerry and phone navigation aids: Red and green phone buttons for accessing phone features and ending calls, a button with the BlackBerry icon for accessing menus, and a return button.

Due for the Holidays

The Storm should be available from Verizon Wireless in time for the holidays, RIM and Verizon officials said during a press tour earlier this week. But they did not specify an exact shipping date or price.

The device will support Verizon’s EvDO Rev. A network (where available) in the United States, but it will also be able to roam internationally on high-speed GSM networks (in Europe, on Verizon stakeholder Vodafone’s network). The Storm also supports both assisted and standard GPS (assisted GPS works with the cellular network to speed up location fixes) and Bluetooth. (However, unlike the iPhone, it does not support Wi-Fi.)

While the Storm dispenses with RIM’s signature QWERTY hardware keyboard in favor of a capacitive touch-screen interface, it’s clearly no iPhone clone. RIM’s device is both shorter (4.4 inches versus the iPhone’s 4.5 inches) and thicker (0.55 inch versus the iPhone’s 0.48 inches) than Apple’s; the touch screen is also somewhat smaller (the iPhone’s is 3.5 inches, while the Storm’s is 3.25 inches). Nevertheless, the display’s 360-by-480 resolution looks pretty sharp at that size.

Also making a good first impression is the 3.2-megapixel camera with autoflash, autofocus, 2X digital zoom, and video-capture support.

The Storm weighs nearly 5.5 ounces (versus the iPhone’s 4.7 ounces), perhaps because it carries radios for both major cellular networks (Verizon’s CDMA/EvDO and the GSM/EDGE/UMTS/HSDPA technology for Vodafone in Europe and elsewhere). Verizon officials say it supports even more countries than the carrier’s last world BlackBerry, the BlackBerry 8830, because this model has quad-band EDGE (versus the 8830′s two-band). Note, however, that the Storm supports only the fastest GSM networks (UMTS/HSDPA) on the 2100-MHz band.

The Storm has 1GB of internal storage, but it also has a MicroSD slot and will ship with an 8GB MicroSD card. Also present: a standard 3.5mm headphone jack, and a second external mic (on the back, in addition to the one for voice on the front) that picks up ambient noise data for the built-in noise reduction technology, which in theory should improve voice call quality. The Storm, like the iPhone, has an accelerometer that adjusts the display’s orientation as you rotate the device.

But the Storm’s most interesting and potentially controversial innovation is RIM’s implementation of a touch interface, especially for typing. The Storm provides three different software keyboards: When you’re holding it in landscape orientation and you need to enter text, a standard QWERTY software keyboard appears; the keys flash blue when you depress them.

In portrait mode, you have a choice: You can have a software keyboard that looks like the one on the Pearl (20 keys, some with one character, others with two) and that supports RIM’s SureType predictive text entry system. Or you can opt for a standard phone keypad (although why you’d want to enter text by multiple letter taps is beyond me).

Only time and hands-on testing will tell whether the Click-Through technology will make text entry and navigation easier (for example, by helping to avoid inadvertent finger taps) or more confusing (the device has a number of tap-and-click shortcuts that take some getting used to).

Visual Voicemail and More

The Storm’s phone-related features include so-called visual voicemail. As on the iPhone, this allows you to peruse a list of incoming calls (identified by caller ID number or, if the number is in your address book, by name) and address them in whatever order you wish.

Like all BlackBerry devices, the Storm will have BlackBerry’s first-rate e-mail features, including support for just about all corporate e-mail systems via the BlackBerry Enterprise Server. The Storm will also ship with Verizon’s VZ Navigator software (but service charges apply) and with instant messaging clients for the major IM services.

However, there’s no universal IM client for the Storm, so if your buddies patronize different services you’ll have to run all of them in the background.

The Storm will support at least limited functionality for most older BlackBerry applications. But at launch, RIM says it will offer a developer’s kit that will make it easier to adapt existing BlackBerry apps for the Storm–for example, optimizing them to take advantage of the touch screen, the accelerometer, or both.

You’ll be able to buy, download and install apps from the VZ Apps Zone over the air, RIM says. And the Storm has one feature that many iPhone 3G users have moaned about missing: It lets you cut and paste text.

Verizon to offer Motorola Krave ZN4 exclusively

Filed under: Uncategorized — info @ 1:36 pm

It’s a touchscreen phone. It’s a flip phone. It’s a touchscreen phone and a flip phone.

At an online media event this morning, Motorola released their rumored new flip phone, the Krave ZN4, to be sold exclusively through Verizon Wireless.

The CDMA EV-DO 800/1900 MHz phone has a clear flip cover over the actual phone, allowing users to access touch features while the flip is still down. The phone comes with an accelerometer, like in Apple’s iPhone 3G, and allows for video viewing in landscape view. Also like the iPhone, a digital QWERTY keyboard appears when the phone is turn horizontally. It also has Verizon’s OpenWave HTML browser.

Besides some of the standard Verizon features like V Cast TV, Rhapsody Music and VZ Navigator GPS Service, the phone has digital voicemail service, where users can pause and rewind messages. It also has a basic email service that has access to Yahoo, AOL, Windows Live and other POP/IMAP clients. It has a 2 megapixel camera, an external microSD slot with availability for up to 8GB of memory (130MB comes standard) and stereo Bluetooth.

The phone is priced at $149.99 after a $50 mail-in rebate with a two-year service contract. The phone retails for $349.99.

Canada’s CDMA operators changed to HSPA/LTE

Filed under: Uncategorized — info @ 1:08 pm

Canada’s Bell Canada and Telus Mobility announced plans to overlay their CDMA networks with HSPA technology by 2010 with an eventual move to LTE technology. The announcement builds on the CDMA network-sharing deal the two CDMA operators have had in place since 2001.

The move follows Verizon Wireless’ decision to deploy LTE in the 700 MHz spectrum it won earlier this year. However, Verizon is skipping an HSPA deployment, choosing to continue investing in its EV-DO network that will likely complement the new LTE network for some time. Telus said the HSPA deployment would enable “a smoother transition to long term evolution (LTE) technology.”

“Bell’s transition to the global 4G LTE standard with a combined EV-DO and HSPA network path aligns us with more than 30 major carriers worldwide planning a similar move to LTE,” said Stephen Howe, CTO with the operator. “This broad global technology ecosystem will mean a fast, efficient and cost-effective network transition to 4G LTE, and access to the broadest possible range of next-generation phones and data services.”

Telus Mobility and Bell Canada both won spectrum in Canada’s AWS-1 auction.

CDMA2000® SURPASSES 400 MILLION SUBSCRIBERS WORLDWIDE IN Q2 2007

Filed under: Uncategorized — info @ 2:50 pm

 CDMA2000 1xEV-DO Subscriber Base Grows by More Than 10 Million, Exceeding 75 Million Wireless Broadband Subscribers  

COSTA MESA, CALIF. — September 10, 2007 — The CDMA Development Group (CDG) today announced a very strong second quarter for CDMA and CDMA2000®, with major milestones, further strengthening its position as the leading 3G and mobile broadband technology in the market: 

  • The cumulative cdmaOne ™ and CDMA2000 subscriber base surpassed 400 million users worldwide, driven by strong demand for 3G CDMA2000 services. Close to 93 percent of the 400 million subscriber base now access CDMA2000 technologies. 

  • The 1xEV-DO subscriber base reached 75 million users, and now accounts for 94 percent of the mobile broadband market worldwide. 

  • There are more than 378 million 3G CDMA2000 subscribers in 97 countries. CDMA2000 continues to be the dominant and most widely available 3G technology worldwide. 

“CDMA2000’s performance, flexibility and first-to-market advantages are no doubt at the core of the technology’s sustained growth,” said James Person, chief operating officer at the CDG. “The economic advantages of the technology—including its suitability for densely populated cities and remote areas —have established CDMA2000 as the leading platform for delivering telecommunication services across diverse global markets.” 

1xEV-DO added 10 million new users in the second quarter and nearly 40 million in the year between June 2006 and June 2007. The CDG maintains its prediction that the number of 1xEV-DO subscribers will surpass the 100-million-user milestone in the fourth quarter —making it by far the leading mobile broadband technology worldwide. 

Sustaining the rapid growth that occurred in the first quarter 2007, the second quarter saw the addition of close to 27 million CDMA2000 subscribers, bringing the total base just shy of 378 million users. CDMA2000 continues to grow at more than 100 million new subscribers per year, significantly outpacing WCDMA growth. The expansion of CDMA2000 is fueled by its superior voice quality, high-speed broadband access, lower network total cost of ownership, and the growing availability and affordability of devices and services. As a result, CDMA2000 has become the technology of choice in developing as well as emerging markets 

In total, CDMA technologies grew at 20 percent in the year between June 2006 and 2007, with the strongest growth coming from the Asia Pacific region, followed by North America, Europe, the Middle East and Africa. Asia Pacific accounts for 47 percent of the global CDMA market, and from June 2006 to June 2007, more than 45 million new CDMA subscribers were added in the region. Most of the expansion has occurred in China and India, the world’s fastest-growing wireless markets, and Korea and Japan, the world’s most advanced mobile markets. North America (including the U.S. and Canada) saw a surge of nearly 17 million new users in year-over-year growth and, with 132 million subscribers, it now accounts for more than 51 percent of the wireless market in the region. Europe, the Middle East and Africa added more than 4 million subscribers in the past year, boding well for the growth of CDMA2000 in markets historically dominated by competing technologies.

CDMA Claims 3G Lead

Filed under: Uncategorized — info @ 12:16 pm

COSTA MESA, Calif. — The CDMA Development Group (CDG) (http://www.cdg.org) announced today that the number of CDMA2000(r) operators reached 143 at the end of the last year, and the technology is now deployed in 67 countries across 6 continents. Furthermore, the number of 1xEV-DO networks nearly doubled from 16 to 29 in 2005, highlighting the industry’s rapid transition to advanced broadband wireless services. CDMA2000 momentum will continue in 2006, with 30 new operators scheduled to deploy commercial networks (compared to 20 last year) and 21 additional trials underway. The number of 1xEV-DO networks will reach 70 in the coming months, and 1xEV-DO Rev A will enter the commercial phase.
“CDMA2000 is rapidly expanding across all markets, demonstrating that 3G is the technology of choice for developed and developing countries,” said Perry LaForge, executive director of the CDG. “CDMA2000 is the most widely deployed 3G technology today, already serving 10% of the total wireless users worldwide, and is at least two years ahead in the evolution to broadband and next generation all-IP services.”

 

 

Designed to support in-band migration as well as new frequencies allocated to IMT-2000, CDMA2000 has been deployed by cdmaOne(tm), TDMA, analog and Greenfield operators across a broad range of frequencies including the 450, 800, 1700, 1900 and 2100 MHz bands in Africa, Asia, North and Latin America, and Europe. First introduced by operators in the advanced wireless markets of Asia and North America, CDMA2000 has quickly spread to developing regions; today, Latin America, South East and Central Asia and Africa are the fastest growing markets for CDMA2000, accounting for more than 50% of all networks deployed.
Asia is still the largest market for CDMA2000 with 36 operators in 19 countries, including China, India, Japan, Korea, Taiwan and Indonesia. Asian CDMA2000 operators are leaders in commercializing advanced wireless technologies; Korea was first to introduce 1xEV-DO broadband services, and now seven operators in the region have launched it and 11 more are in deployment.
Most cdmaOne carriers and a number of TDMA operators in North America have migrated to CDMA2000. There are 26 operators offering CDMA2000 1X services and seven have deployed 1xEV-DO, including Verizon Wireless, Sprint Nextel, and Alltel. One more 1X and 3 1xEV-DO networks are scheduled to be commercial in 2006.

Introduction to CDMA technology

Filed under: Uncategorized — info @ 9:30 am

CDMA is one if the majoe global wireless mobile technology standards. Other standards being GSM and TDMA Code division multiple access (CDMA) is a form of multiplexing (not a modulation scheme) and a method of multiple access that does not divide up the channel by time (as in TDMA), or frequency (as in FDMA), but instead encodes data with a certain code associated with a channel and uses the constructive interference properties of the signal medium to perform the multiplexing. CDMA also refers to digital cellular telephony systems that make use of this multiple access scheme, such as those pioneered by Qualcomm, or W-CDMA. CDMA is primarily a North American technology developed by Department of defence first and perfected by Qualcomm. GSM is primarily European technology
