The one thing that remains when going out and choosing the right satellite navigation system is choosing the right one. With the help of the following satellite navigation review, it should help you decide on the best and most well-suited system for you.

Sat nav systems are increasing in popularity, in addition it is becoming more affordable, whichever way you look at it. Now with the help of this satellite navigation review, you will be able to look at all the systems that are available to you. In this satellite navigation review you will know the things to look at when you decide to buy one and a few ups and downs will also be mentioned in this sat nav review.

There are about three categories, and first, there are those that are dedicated and these fall under the ‘transferable categories’. The main function of these systems is that their function is to navigate. Nowadays, they are appearing with newer features like hard drives used for storing music.

Now there are the systems that use personal digital assistant or PDA. They are in some cases more expensive than a transferable device.

Finally, the Smartphone can be turned into an in-the-car navigation system. They can be expensive, but the advantage is that these can be more portable than any of the other options mentioned above.

It is important that you remember that cars come out with heated widescreen, glass that is heat-reflective and elements that can thaw ice in winter. These can disrupt the sat signals from loading onto the device. In this case you need an external antenna fitted to your car.

People that have produced these systems have agreements, and this means that you will not ever pay. However, others will charge you subscription charges after a certain period.

There are many misconceptions about IPTV, but Geof Heydon, Director of Innovation and Market Development at Alcatel, is an expert in the IPTV future. In this interview he separates fact from fallacy in the IPTV and “multi-service network” world. For one thing, IPTV is delivered over a separate IP network that is not the Internet. It is not something you can do on the Web today (or even in the future). It is about offering video in all its forms, TV on demand, free-to-air TV and even pay-TV together – and richly imbued with simultaneously available multiple broadband connections, Voice Over IP phone circuits, video conferences and so on. But it will take place on a very different kind of network from those in use in Australia today.

Heydon explains the work to evolve the existing broadband networks towards IPTV, but also the entirely new networks that may be built to succeed the existing HFC cable when the latter wears out. Only new networks will be able to overcome the high “background contention ratios” that prevent today’s networks from delivering the end-to-end performance needed for IPTV. It is that high speed that allows IPTV features such as quick channel changes. ADSL2+ is a major upgrade to the access component of the network and that is one significant requirement of IPTV.

But that’s just a start, says Heydon. You also need the network backbone to be upgraded, and for a small country such as Australia, it is not clear that the market can be allowed to look after itself without a visionary Government ensuring faster networks are implemented via a sensible regime of new incentives to the broadband industry. Heydon talks about the issues that have faced SBC, a telco in the USA that is using IPTV from Alcatel and Microsoft to wage combat against the leaching of triple play cable competition. (The SBC IPTV offering is expected to light up at the end of this year.) Heydon talks about broadband companies in places such as Italy, where FastWEB has many lessons for the Asia Pacific region.

Heydon also talks about the specifics of today’s user experience, with early systems such as the Microsoft Windows Media Centre and the Elgato EyeTV, or the Foxtel IQ PVR, offering the first glimpse of the IPTV benefits, but nowhere near the actual promise of a fully realised IPTV regime. Trickle fed video services on today’s Internet can’t deliver Standard Definition, let alone High Definition channels, with hundreds of such channels being instantly accessible. That requires a lot more network sophistication and a TV-oriented experience, rather than a PC-oriented experience.

And such a unified delivery system also establishes a unified TCP/IP environment so that 3G networks’ video-capable mobile handsets will seamlessly interoperate with the TV world, allowing applications to interoperate across both platforms with video shared and used appropriately on each. That means a unified user identification system, with a dramatic decrease in the number of passwords people will need to remember. It also means a much better capacity for the network to intuit each user’s needs based on its understanding of the user’s personal wants and needs as they assume each “personality” in their broadband life. Notwithstanding the potentially chilling confidentiality issues, one result will be that TV will serve different advertisements to children, as compared with when the parents watch TV later in the evening. It means a game player’s profile in shoot ‘em ups (established during that person’s teen years) will be maintained separately from that player’s more sober business profile during a day in the office.

In the IPTV world, it will also be possible for each device in a consumer’s life to control or access each other device. For example, a parent may use a Personal Digital Assistant while on the road, to transmit a message to the TV screen telling the children it is time for bed.

Heydon describes a metaphor: when water and electricity were installed a century ago, no one anticipated the dishwasher or clothes washing machine. But the way those early utility services, once so separate, eventually converged into new forms so useful that they are almost ubiquitous throughout the developed world, is a signpost to how today’s broadband services are likely to mix and match into new and ubiquitous forms in coming years.

And that thinking raises the vital issue of how entrepreneurs and technology strategists will profit from these changes. Heydon describes some of the new businesses and new products envisaged today, that will forge the profitable broadband value propositions of the next decade. News & Politics Kimberly Caldwell

David Little asked:


“Just what do you think you’re doing, Dave?” Those words, made famous by the artificially intelligent computer HAL 9000 in Stanley Kubrick’s “2001: A Space Odyssey” resound in my ears every time I think about the topic of this week’s article: virtual assistants.

For those of you too young to recall, HAL was the artificially intelligent computer aboard Discovery in the film that attended to the myriad of details requiring oversight as the ship’s crew made its way to Jupiter. Its seemingly omnipresent red camera lens monitored all ship activity.

With HAL’s words still fresh in my memory, even after all of these years, it is with a bit of personal trepidation that I will discuss how digital signage can be used to add a virtual assistant to any sales or marketing process. But don’t worry, with this sort of application there’s no danger of getting sucked out into the cold recesses of space.

As in “2001,” the concept behind a virtual assistant is simple: make a complex process simple and manageable through the use of an efficient, “intelligent” computer. Putting that concept into practice here on earth is helping two Wichita, KS, area businesses extend their sales and marketing efforts and better serve their customers while freeing up personnel for other critical tasks.

At Walnut Valley Garden Center in Andover, KS, outside Wichita, an elaborate, interactive digital signage setup helps customers determine how much product they’ll need for a given landscaping or garden project by combining maps from Google Earth, a digital signage controller from Keywest Technology and an Orion touch-screen LCD panel with a data base of landscaping products that the store carries and their recommended coverage area.

Customers simply type in their names and addresses when using the system, and a map of their individual property is summoned from Google Earth. By touching the screen to define the boundaries of their project, customers trigger a computer to determine the types of products to use and how much they’ll need. For instance, by designating an area on the map, they can learn what type of fertilizer they need for their lawn and how much to buy.

For those who are new to gardening, the system cycles through digital signage presentations encouraging them to touch the screen to select one of 12 different types of gardens. After settling on a design, the system allows customers to interact and tells them exactly what’s needed -including plants, mulch and rocks- to build a similar garden in their yards.

At Randy Dean Construction in Wichita, another interactive digital signage system using a Keywest Technology digital signage controller, a touch-screen sensor interface from ELO and a 32in flat panel LCD greets potential buyers as they enter a model home. While Randy Dean’s sales agent can answer the questions of one buyer, the interactive digital signage system can take other prospective buyers on full 360-degree virtual tours of all Randy Dean homes, access and print floor plans, examine the builder’s home inventory and access the company’s Web site -all without taking the sales agent away from the prospective buyer.

Out-of-home media specialist DSX Media in Wichita designed and delivered both systems, including creating digital signage content, interactive branching and delivering digital signage hardware and software, touch-screen controller and flat panel LCD screen. In the case of Randy Dean Construction, DSX Media also sold advertising contracts to aligned businesses like mortgage bankers and title companies so their commercial messages could be interwoven into a loop of content that plays till the screen is touched.

While the specifics of both applications differ, they share the concept of using interactive digital signage -a hybrid of digital kiosk technology and conventional linear digital signage pages- to boost both businesses’ sales by in essence projecting the presence of a virtual sales assistant to answer many of the questions consumers typically ask. Doing so elevates digital signage to a new plateau, somewhere far beyond the role of an electronic equivalent of a printed sign, where it becomes an integral part of an orchestrated sales process.

Like all analogies, the one between the virtual assistants in Wichita and HAL eventually falls apart. While the garden center and homebuilder applications rely on some pretty specialized data bases to create content on the fly that’s relevant to shoppers, neither uses artificial intelligence like the fictional HAL. Still, the similarity in human-computer interaction, conjures up that all-seeing red camera lens in my mind’s eye.

Which brings me back to where I started this article: “Just what do you think you’re doing, Dave?” Unlike “2001’s” astronaut Dave Bowman, who disconnected the technology, my answer is to turn you on to the possibilities of using interactive digital signage to create virtual assistants like the ones at Randy Dean Construction and Walnut Valley Garden Center to boost your sales success.

ny are confused by the wide-ranging spectrum of mobile phone models and capabilities. For those seeking a phone with the greatest expanse of functionality, there is no better choice than a smart phone.

The smart phone is simply a cellular phone that offers higher capability above the average mobile phone. This simple definition is unfortunately complicated by the lack of an industry standard definition. One may see a smart phone as one that offers a complete keyboard with internet and email functionality, and some may only view a smart phone as a phone with a full operating system (OS) and applications.

Smart phones, as a whole, carry the ability to function as much as a cell phone as a PDA.

Most have complete email capability, web browsing, calendar support, and contact support. Extended functionality offered by various manufacturers and models include GPS or A-GPS navigation, multimedia playback, document reading or editing, integrated camera, touch screen, etc. The smart phones available on the market today are characterized by their respective operating systems, which are:

* Windows Mobile

* iPhone OS

* Symbian OS

* RIM Blackberry

* Palm OS

* Linux-based OS

Windows Mobile is a platform developed by Microsoft that supports mobile devices including smart phones. It is close in appearance and features to the desktop Windows operating systems, including a very large selection of third party applications. Windows Mobile applications can add an unlimited functionality to a smart phone within hardware limits, but some examples are Skype support, instant messaging over AIM or other protocols, RSS feeds, and media players that extend the built-in file format ability.

The iPhone OS is built by Apple to run on their iPhone. The iPhone OS is actually a stripped down, but complete version of the original OS X operating system. This OS supports media playback identical to the iPod line, but with a layout designed to take advantage of the iPhone?s multi-touch screen. It also supports a portable version of the iTunes store, third-party applications through an application store, a full version of the Safari web browser, full e-mail support with HTML and attachment viewing, maps via Google, YouTube, calendar and contacts support, photo viewing, etc.

The Symbian OS is developed and owned by Symbian Ltd., and while similar in functionality to the Windows Mobile operating system, enjoys 65% of all smart phone market share. This OS has all of the basic smart phone features that any other smart phone has, but also an extensive library of third party applications that provide the phone with nearly unlimited functionality (with respect to hardware limitations). Some phone manufacturers that utilize the Symbian OS are Nokia, Motorola, and Sony Ericsson.

The Blackberry, Palm, and Linux-based operating systems are the last three operating systems employed by smart phones today, and share the main functionality of all other smart phones, as well as third-party applications. These systems are similar in their narrow smart phone deployment. The Blackberry OS only runs on Blackberry devices, and the Palm OS runs primarily on the Treo devices. The Linux-based systems are unique in that it is not its own platform, but rather a base for other platforms used by Samsung, Panasonic, NEC, and Vodafone, to name a few.

A digital camera is a camera that takes digital photographs on a light-sensitive sensor. Many digital cameras can also record sound and videos besides still photographs. These cameras can store thousands of images on a small memory space. The users can also edit the stored images. They can also delete the stored images. Deletion of stored images will free the device’s memory which can then again be used for taking more photographs.

The digital cameras now-a-days are being incorporated into devices like mobile phones & personal digital assistants (PDAs) and vehicles. There are various types of digital cameras like video cameras, line-scan cameras, bridge cameras and live-preview cameras. The video cameras are further classified as camcorders, professional video cameras and web-cams. While a web-cam is attached to computers for video conference purposes, a camcorder is meant for the use of amateur photographers.

A Bridge camera often has a super-zoom camera lens that provides a very wide zoom range. These cameras are often confused with digital SLR cameras as their appearance is similar to each other. Many of the Bridge cameras store images inloss-less RAW format. They are generally lighter that DSLR cameras and provide images of good quality. Most of the compact digital cameras store images in Tagged Image File Format (TIFF) and Joint Photography Experts Group (JPEG) file formats. Some cameras also use formats like Design Rule for Camera Format (DCF), Digital Print Order Format (DPOF) and Exchangeable Image File Format (Exif).

Zoom camera lenses are designated as 3x, 4x, 5x etc. These designations refer to the ratio between the longest and shortest focal lengths. A larger zoom designation does not necessarily mean that the image cannot be magnified any more. A zoom lens is one wherein a photographer can vary the focal length of the camera lens within a predefined range. The zoom lens allows users to achieve a variety of perspectives and compositions. These zoom lenses come handy when the user has to capture images of a dynamic subject matter like an athletics event.

Personal Data Assistant (PDA) won quick acceptance among students and managers who are constantly on the move, because her ability to package different data requirements for palm-sized devices. CPC is designed to make life easier for busy by providing reasonable connections to all the information you need, it is at your fingertips, when you need, and other transportation systems. After the “organized” with your device, you get all their contact numbers, will collect your mail, the process of ordering your business, show your pictures and relax your mp3 library. Many device also features digital recording and windows on the basis of compatibility for word processing and spreadsheet financial calculations.

At the end of the simplest device market, a pocket can help you manage your day-do lists, keep track of your diary and write memos. But it is important for people coming in using PDA realize that this is a tool that is the most advantageous for the already organized mind: he will not actually in the organization for you. But if you think you want to view and manage documents on the go, track your appointments and instant access to your name and address book, and then the main functions of a pocket, perhaps, increase your productivity. And, of course, add bonuses to your mp3s, watch a short video, reading ebooks and the opportunity to repeat and review your presentations can only help.

CPC with the Windows Pocket PC operating system and gutsy memories that are compatible with your usual windows and office environments. The size of the screen and the image can be critical if you intend to use the device for reading books and the management of text-heavy documents. While sales of CPC steadily declined over the past two years, losing to Smartphone technology, the major manufacturers make fitness PDA devices with faster processors, increasing memory and multimedia capabilities. In many situations, smartphones have been able to replace many of the functions of the PDA, combining data from mobile phone technology. But if you want to work with spreadsheets and Web pages on your device, smartphones are at a disadvantage small screen size and data storage capabilities, and sometimes cost, but also eliminates the need to carry two devices.

With search

There, such a manual PDA devices, taking into account virtually every budget and need. You should consider how the data you want to carry with you and how you want to be connected. Obviously, more memory, faster processor and screen are attracting more high price tags. You can compare brands, models and prices Myshopping.com.au search using the following specifications to you.

The budget may propose cell processor speed of 16 MHz, 8 MB of memory and 2.5 inch (diagonal) screen. At the high end, you can get 4 GB micro hard drive, WiFi and Bluetooth communications, 400 MHz processor, 256MB of memory, with the expansion slots, 4-inch (diagonal) LCD screen with 65000 colors and 640 x 480 display resolution, GPS functionality, MP3 player, digital camera and instant communications. In the middle of the circle, you will find a device with 64 MB of memory, 200 MHz processor, 3 inch screen, built-in microphone and audio input jack. Keep in mind that all of these characteristics and functional changes constantly, and conversion devices with new features in a very short space of time.

Apart from the speed of the processor, memory and screen size, some major features that can be used to compare the value of the brand and include:

Data input-While some models have full QWERTY keyboard built-in, you may want to consider adding fold-up to full size external keyboard. Entering a lot of text with a small built-in keypads or using software by hand can be frustrating.

Audio materials-A built-in microphone or a microphone to record Nest must voice memos and meeting notes and store audio files.

Playing music-MP3 audio playback sometimes need additional software.

GPS-Although there are a number of purposes hand-built devices for industrial applications, your GPS device in capacity may not be suitable for the rugged outdoors.

Make-Look integrated Bluetooth 1.1 and a built-in 802.11b wireless adapter

Smartphone – Combines functions with a phone device data management in a single block. Phone capability requires separately purchased contract

Audio Output-A headphone connector is important to listen to audio files

Cradle / Charger is a device allows for easy communication and synchronization with a PC and recharge your batteries at the same time. Consider purchasing additional cradle for the office for maximum convenience. Some device includes a cable or a special cradle that provides an interface to your desktop computer to synchronize data.

Battery life Each device will have its own battery life characteristics. Battery life also depends on the data you are processing. You can use the manufacturer as a guide for comparison between brands and models, but these characteristics and laboratory measurements may not reflect actual usage.

Bluetooth is a wireless technology enables the exchange of data with other handheld devices, or any other Bluetooth enabled device as a mobile phone, fax machine, personal computer, personal computer, headset or printer. In Bluetooth feature will allow you to add external keyboard.

Digital camera-PDA usually cameras capture images with low resolution (approximately 1.2 megapixels), which are ideal for e-mail, but not suitable for print.

GPS-Global Positioning System allows you to navigate from any point on or near the earth’s surface.

Music / Audio-in MP3 playback quality will depend on the bit rate of quality audio and built-in speaker. At the sound quality is often better when plays back through a headset quality.

PDA Screen-screen device sizes are measured in inches diagonally and are available from 2.6 inches to 5 inches on the very high end. Larger, brighter screens require more power to act to increase the consumption of batteries.

The processor speed of the speed in which the PDA is coordinating its internal functions. Processor speed is measured in MHz (MHz) and range between 4 MHz and 624 MHz. While these characteristics may change rapidly as technology develops, it is recommended to have a processor speed of at least 16 MHz for the general day-to-day functions.

Hostage video-playback video often requires additional expansion cards and third-party software downloads, and higher capacity memory.

Browser-Used with a wireless connection allows you to view the Internet as you, through your computer.

Wireless LAN Internet-Integrated 802.11b WLAN (wireless local area network), allowing connect to the Internet at any hot spot. Securing the wireless function tended to consume batteries quickly.

As a result,

You can consider you newcomers (ie new technology for PDA), a businessman or technophile and make your search based on your level of understanding of technology involved. As a novice, you will be looking for cell as technophile you are looking for all the bells and whistles. Businesses will be looking for more opportunities to adapt. The following might help.

Choose between functions. Consider the need for mp3 players, and video players, or a Web browser. Doubling the functionality of your device can reduce the need to solve another device around to enjoy the benefits offered.

How much access to the Internet, you will need? Bluetooth connectivity can give you the opportunity to mobile phone access to the Internet, the wife may give you access from hot spots, and a simple cable connection to your desktop computer can let you read your email on the road.

Go for the maximum memory on the money. Memory determines how much data your device can handle and store, and its ability to process applications. Memory can be increased in many devices using expansion slots and memory cards.
