About BlackBerry

2007-04-26T07:17:00.000-07:00

From Wikipedia, the free encyclopedia

The BlackBerry is a wireless handheld device introduced in 1999 which supports push e-mail, mobile telephone, text messaging, internet faxing, web browsing and other wireless information services. Developed by the Canadian company Research In Motion (RIM), it delivers information over the wireless data networks of mobile phone service companies. BlackBerry first made headway in the marketplace by concentrating on e-mail. RIM currently offers BlackBerry e-mail service to non-BlackBerry devices, such as the Palm Treo, through the BlackBerry Connect software. The original BlackBerry device had a monochrome display, but all prevalent models have color displays.

While including the usual PDA applications (address book, calendar, to-do lists, etc.) as well as telephone capabilities on newer models, the BlackBerry is primarily known for its ability to send and receive e-mail wherever it can access an atmosphere wireless network of certain cellular phone carriers. It has a built-in keyboard, optimized for "thumbing", the use of only the thumbs to type. System navigation is primarily accomplished by the trackwheel (or "thumbwheel"), a scrolling wheel with a "click" function, located on the right side of the device. Some models (currently, those manufactured for use with Nextel, TELUS, and other iDEN networks) also incorporate a two-way radio. Some BlackBerry devices don't depend on mobile phone service coverage and are Wi-Fi compatible like similar handheld devices that are on the marketplace.

The Future of Wireless Broadband - 3G, 4G, WiMAX.. Who Knows

2007-04-24T08:09:00.000-07:00

WiMAX, LTE, UMB, Wi-Fi, 3G, 4G, EV-DO, HSDPA, UTMS, MIMO, 3GPPP, OFDM, CDMA… How do we keep up with it all?

The number of different technologies, standards, companies going after the wireless Holy Grail of ubiquitous broadband will make your head spin. At WiMax.com we will do what we can to keep everyone informed on how WiMAX will fit into this alphabet soup of standards and technologies, but it won't be easy.

For example, last week I read an interesting article on how 3G is now available in every country of the world. To me that is truly amazing. I am still trying to figure out what exactly is 3G and why I would need to upgrade. In my home town of Austin, TX, I see my service provider advertising their 3G/Broadband service, but for some reason I still haven't upgraded. I am in the wireless business with a high-demand for an always-on high-speed service, but for some reason I still search daily for Wi-Fi hotspots to connect to the Internet. If I am not upgrading to 3G, I am sure others aren't upgrading as well.

So if 3G can do all these amazing things then why do we need 4G, WIMAX, UMB, LTE and all these other future technologies and acronyms? The reason is because the Internet is unleashing a flood of new bandwidth intensive applications that will tax all the wireless carriers' network capacity. Old networks have to be upgraded and optimized, new networks have to be built from the ground up to handle this new flood of applications. At the same time service providers will still need to offer good quality voice service or run the risk of losing customers to other providers. Over the next decade, new wireless technologies, ecosystems, business models and companies will be developed. Some will succeed, many will fail. Over time, the market will weed out the good from bad.....it always does.

Xandros Desktop Professional [Review]

2007-04-17T05:54:00.000-07:00

"With an interface that is quite similar to classic Windows, along with utilities that target Windows migrations, Xandros Desktop Professional is a good choice for a productivity desktop and can rival more popular distributions, although bugged from design inconsistencies and a strict licensing structure.

"If you have used other Linux distributions like Ubuntu or OpenSuSE, when booting up Xandros Desktop Professional for the first time, you can't help but feel unimpressed by the overall packaging of the product..."

WiMAX Spectrum More Economical Than 3G

2007-04-10T08:05:00.000-07:00

Robert Hoskins
Broadband Wireless Exchange Magazine
January 17, 2006

The price paid per Hz for WiMAX spectrum is as much as 1,000 times lower than for 3G spectrum according to the latest report from leading research firm Maravedis titled “Spectrum Analysis - The Critical Factor in WiMAX versus 3G”. This white paper provides an in-depth review of the economics of spectrum for both 3G and WiMAX around the world.

“The low cost of BWA/WiMAX spectrum compared to 3G is a clear driver for service providers to enter the field of wireless services with WiMAX” explained Adlane Fellah, author of this new research.

The much lower cost of WiMAX/BWA spectrum resulted in a high number of licensees with a total 721 license holders were awarded for BWA/ WiMAX against 106 licensees for 3G.

North America is by far the leading region in terms of the number of BWA/WiMAX licenses awarded with a total of 394 BWA/WiMAX license holders, against 186 licensees in Europe, 97 licensees in Asia, and 49 licensees in the CALA (Caribbean and Latin America) region.

Maravedis’ latest research also revealed that, contrary to 3G licenses, the BWA/WiMAX licenses awarded across the world are essentially regional licenses. North America is a perfect example of a situation where 100% of its WiMAX/BWA licenses are regional. In Europe and the CALA region the proportions are 78% and 71% respectively.

Maravedis predicts that this crowded environment will result into a highly fragmented, unpredictable and more competitive marketplace with smaller and cost-aggressive players.

On the other hand, a low-cost spectrum has also attracted players with more modest pockets than large mobile operators. “One should remember that BWA spectrum was initially allocated for fixed only applications and remains so in many countries,” Fellah added.

The report also suggests that most regulators have not kept pace with the progress of technology that makes fixed-mobile convergence a reality. Whether it is fixed applications with CDMA technology or mobile applications with WiMAX, the two fields are converging and will be competing for a share of the one billion mobile subscribers market.

Maravedis is a leading research and analysis firm focusing on Broadband Wireless technologies including WiMAX, 802.20, TD-CDMA and Wireless Local Loop Systems. Maravedis has established itself over the years as the most credible and reliable resource for market intelligence in the broadband wireless industry. Maravedis works with equipment vendors, service providers, regulators and the investment community to produce a sound market analysis based on hard primary data and on in-depth understanding of technology, market and regulation trends.

WiMAX Broadband Wireless Technology Access

2007-04-07T04:46:00.000-07:00

What is WiMAX

WiMAX (World Interoperability for Microwave Access), based on the IEEE 802.16 standard, is expected to enable true broadband speeds over wireless networks at a cost point to enable mass market adoption. WiMAX is the only wireless standard today that has the ability to deliver true broadband speeds and help make the vision of pervasive connectivity a reality.

There are two main applications of WiMAX today: fixed WiMAX applications are point-to-multipoint enabling broadband access to homes and businesses, whereas mobile WiMAX offers the full mobility of cellular networks at true broadband speeds. Both fixed and mobile applications of WiMAX are engineered to help deliver ubiquitous, high-throughput broadband wireless services at a low cost.

Experience your mobile entertainment center Mobile WiMAX is based on OFDMA (Orthogonal Frequency Division Multiple Access) technology which has inherent advantages in throughput, latency, spectral efficiency, and advanced antennae support; ultimately enabling it to provide higher performance than today's wide area wireless technologies. Furthermore, many next generation 4G wireless technologies may evolve towards OFDMA and all IP-based networks as an ideal for delivering cost-effective wireless data services.

Intel is poised to deliver the key components needed for successful WiMAX networks. It delivered the fixed WiMAX solution, Intel® PRO/Wireless 5116 wireless modem, and is now shipping a fixed/mobile dual-mode solution, Intel® WiMAX Connection 2250. This highly cost-effective solution was designed to support both standards with an easy upgrade path from fixed to mobile and is expected to further accelerate the deployment of WiMAX networks.

Mobile applications

Some cellular companies are evaluating WiMAX as a means of increasing bandwidth for a variety of data-intensive applications; indeed, Sprint Nextel has announced in mid-2006 that it would be investing about US$ 3 billion in a WiMAX technology buildout over the next few years[1].

In line with these possible applications is the technology's ability to serve as a high bandwidth "backhaul" for Internet or cellular phone traffic from remote areas back to an Internet backbone. Although the cost-effectiveness of WiMAX in a remote application will be higher, it is not limited to such applications, and may be an answer to reducing the cost of T1/E1 backhaul as well. Given the limited wired infrastructure in some developing countries, the costs to install a WiMAX station in conjunction with an existing cellular tower or even as a solitary hub are likely to be small in comparison to developing a wired solution. Areas of low population density and flat terrain are particularly suited to WiMAX and its range. For countries that have skipped wired infrastructure as a result of prohibitive costs and unsympathetic geography, WiMAX can enhance wireless infrastructure in an inexpensive, decentralized, deployment-friendly and effective manner.

What Is A Weblog?

2007-04-05T08:51:00.000-07:00

A weblog is just a web site organized by time.

I say 'just' because the hype around weblogs makes them both more and less than they are. Weblogs do not represent something brand new in human communication. Diaries closely resemble weblogs and be traced back as far as ancient Greece.

On the other hand, weblogs are not just a vehicle for navel-gazing by their authors ... unless authors are especially fond of such. It is permitted, just generaly ignored by readers. Too much lint is involved.

Weblogs are Updated Websites

Every website that is updated at least once (this applies to 99.9% of all websites)can be considered a weblog because it contains two entries - whether those entries are called 'posts' or 'stories'.

Any two website items are tacitly organized by time, whether or not an actual date is attached to either of them. One item is earlier than the other; the other was published later than the first one.

Weblogs make the organization of the time-dimension explicit by providing a calendar through which each entry can be retrieved.

Why Weblogs?

Certainly, weblogs have carved out a well-deserved conceptual niche within the Internet ecology.

Templates make it easy to start a site without cracking the arcana of web design or programming.

Editing, posting and generation of the (weblog) website is largely automated.

The simple addition of a calendar (whether text or graphical) joined to the now-familiar hyperlink offers 'more than the sum' of those two simple parts for helping readers orient themselves.

Still, "A weblog is just a web site organized by time."

This matters for two reasons.

First, Define Your Own Objectives

Many beginning bloggers are intimidated by the quite legitimate questions, "do I really have anything to say" and "why should anyone want to read what I write?"

Of course, if the answer to the first question is "no", then creating a web site is silly.

But the answer to the second question is more complicated. Probably, very few people will care about what you write - certainly at the beginning but maybe ever. But this does not necessarily mean that your weblog - your website - is an effort in futility.

Public readership beyond family and friends is a bonus but only you should define whether or not it is a key objective.

Reminding yourself that your weblog is just a website can be very liberating. Many thousands of bloggers have discovered that speaking in their own voice draws a surprising response from friends ... and strangers who become friends.

Second, Suit Yourself

A calendar can be intimidating. Is there any point to a weblog - a website - that is only updated once a week? Once a month? Once a year?

That depends on many factors that go to the heart of why you wish to create a website in the first place. Happily, the last I checked, weblogs contain no explosive devices aimed at those who post material infrequently.

Most weblog tools (and Radio more than most) provide a ready-to-hand design framework. All the author has to do is add 'water' - their content. This ease-of-entry ensures that just about anyone (even you and me) can put their drivel on the Internet without a second thought. Welcome to the Web! I like my drivel ...

Far from negating the value of your weblog or the Internet in general, this validates its benefits. Why shouldn't individuals - just folks - be free to express themselves publicly? Until the past ten years, cultural gatekeepers (publishing businesses across all media) filtered out all but those exceedingly few creators who could make them a buck. Their junk is far slicker than ours but it still smells.

Your weblog may endure for one post or across many decades to come. It may be read sometime by millions or only by yourself as a record of ideas, events and deeds that mattered to you. If it gives you pleasure, you will continue. If it doesn't, you will stop.

And why not?

A weblog is just a web site organized by time

Windows Vista

2007-04-05T08:32:00.000-07:00

Windows Vista is the latest release of Microsoft Windows, a line of graphical operating systems used on personal computers, including home and business desktops, notebook computers, Tablet PCs, and media centers. Prior to its announcement on July 22, 2005, Windows Vista was known by its codename "Longhorn".[1] Development was completed on November 8, 2006; over the following three months it was released in stages to computer hardware and software manufacturers, business customers, and retail channels. On January 30, 2007, it was released worldwide to the general public,[2] and was made available for purchase and downloading from Microsoft's web site.[3] The release of Windows Vista comes more than five years after the introduction of its predecessor, Windows XP, making it the longest time span between two releases of Windows versions.

Windows Vista contains hundreds of new features; some of the most significant include an updated graphical user interface (GUI) and visual style dubbed Windows Aero, improved searching features, new multimedia creation tools such as Windows DVD Maker, and completely redesigned networking, audio, print, and display sub-systems. Vista also aims to increase the level of communication between machines on a home network using peer-to-peer technology, making it easier to share files and digital media between computers and devices. For developers, Vista includes version 3.0 of the .NET Framework, which aims to make it significantly easier for developers to write high-quality applications than with the traditional Windows API.

Microsoft's primary stated objective with Windows Vista, however, has been to improve the state of security in the Windows operating system.[4] One common criticism of Windows XP and its predecessors has been their commonly exploited security vulnerabilities and overall susceptibility to malware, viruses and buffer overflows. In light of this, Microsoft chairman Bill Gates announced in early 2002 a company-wide 'Trustworthy Computing initiative' which aims to incorporate security work into every aspect of software development at the company. Microsoft stated that it prioritized improving the security of Windows XP and Windows Server 2003 above finishing Windows Vista, thus delaying its completion.[5]

During the course of its development, Windows Vista has been the target of a number of negative assessments by various groups. Criticism of Windows Vista has included protracted development time, more restrictive licensing terms, the inclusion of a number of new Digital Rights Management technologies aimed at restricting the copying of protected digital media, and the other new features such as User Account Control.
