Author: The utility of the `global positioning system` or GPS as it is more commonly known is tremendous and GPS cell phones are the latest innovations using tracking system. These phones can identify your location as well as the nearby areas and also give step-by-step direction to your destination. Of course, the right software and service package has to be loaded on to it for the cell phone to become GPS enabled.
If used within the automobile, the GPS cellular phones work with a receiver. By subscribing to a navigation service and inserting the right software which is in conjunction with your phone, the system allows you to receive driving directions. If you wish to use the tracking system outside the automobile, then an integrated GPS cell phone is required.
People who are constantly on the move will find the GPS cellular phones a handy device as their movements can be tracked. It will allow you to call for assistance from anywhere and your location will be tracked. For instance, if your car has an accident in a remote area, emergency help can easily be reached to you with the help of this tracking system. Even for the average hiker in the mountains or the woods, this device has become indispensable as it means being able to call for help instantly if the person is injured or in any danger.
Cell phones are continuously transmitting and receiving signals to and from the operator tower which is nearest to its location. Wireless communication has made it possible that the cell phone is active even in the standby mode. GPS cellular phones work on the same premises as the navigation tool which is generally used for remote trips. Cell phones are thus equally easy to trace and both GSM as well as CDMA phones which are GPS integrated, can be tracked using the system.
The mechanism of the GPS devices is that the signals received from these cell phones are identified by the service provider by identifying the operator/operators nearest to the location. These numbers are then compared with the relative strength of the signals received and the strongest signal is then identified. This procedure enables the cellular phone to be tracked within 100 meters of its exact location. This is very useful if the person is lost or in danger or unfortunately, as has become more common in today`s times, to trace a potential terrorist or miscreant.
Another add on to this invention is the child GPS locater device which if integrated in your phone is going to give you immense peace of mind as a parent. You will know exactly where the child is all the time by just looking at your cellular phone and you can check on the child silently without having to call him up 20 times! Of course, parents, please be aware that, morally, this does not mean a license to snoop but is meant for keeping a genuine look-out for your child when he is away from home. And even when the child or children are with you, the GPS cellular phones are an amazing comfort in over-crowded places like amusement parks or shopping malls where children are likely to get lost.
Of course, with any advanced technology the issue of privacy always raises its ugly head. But, that is the price one may have to pay for convenience`s sake and regular check-up of the device for malicious software, updating cell phone features with the service giver and having a predetermined tacking system with family and friends will help you make the optimum use of this technology.

Has anyone thought on how Video conferencing came about to be what it is in the present time? Video conference started on the idea based upon the Television transmission. This is usually a one way output for the observer and no input from the viewers.
Then came the Video Teleconferencing technique which is based upon input and output from the users. The input and output is the sending and receiving ofaudio and video signals. The equipments used at the start of this method were: video cameras and screens; microphones with input and output facilities; speakers; and special transmission equipment for receiving and sending out signals at the location for the conference to take place.
When a conference would hold, all the members taking part would have to be present as a group in a room at the same time at each location. The signals sent and received were slow with low video conferencing definition.
This soon led to the introduction of wireless communication. The technology used for a Video Conferencing has now expanded gradually over time to make this a cost effective mode of communication.
With the introduction of the Internet, some companies are now offering ISDN and IP to make transmission fast and with high video conferencing definition. Without special equipments needed for conferencing, communication can not be carried out. So it is also necessary to find those companies that offer these special equipments. Video conferencing can now be carried out at one’s desktop with the introduction of the latest technology.
One has to wonder, how much further technology can go; it seems endless.
Video conferencing is a power means of having face to face conversation without the hassles of travel. Logon for here for video conferencing services and solutions.

Specially designed for accessing the internet and wireless communication on the go, Netbooks are considerably smaller and lighter than the average laptop. Ranging in size from 5 – 10 inches Netbooks typically weigh around a kilo. (Average laptops have a screen size of around 15 inches and weigh around 3 kilos).
They are lighter on the pocket too with the average Netbook costing £270 compared to £910 for the average laptop.
Netbooks do not have the same capabilities or memory available as a laptop, the focus is not in built-in applications but online based ones like Google Docs – taking advantage of the current trend towards “Cloud Computing” in which data is managed and stored on servers and not on the machine itself.
An example of “Cloud Computing” is the website Picnik; an online photo editing service that offers a similar functionality to Photoshop. It is easy to use, there is no need to register, nothing to download, install or save on the machine and you can edit and enhance your photos directly through your web browser for free.
Two things to be aware of when looking to purchase a Netbook is the screen size and resolution;
· You may be required to sideways scroll on some sites especially when reading large amounts of text
· Ensure an adequate battery life, due to the Netbooks being primarily designed for computing on the go
The ASUS EEEPC 701 Netbook retails for around £170 and is ultra portable weighing in at a mere 0.905 kg and measuring 225 mm x 160 mm (half the size of A4!). It also features 512 MB memory and 8 GB storage, a 7 inch display screen and a pretty standard 3 hours battery life. This model offers a Linux operating system which means that an optical drive for installing software is not required.
Alternatively the Toshiba NB100-12A Netbook retails for around £262 and offers a Windows XP operating System. It includes an Intel Atom processor, 1GB RAM, 120GB storage, an 8.9 inch display screen. With only 3.5 hours of battery life it may not be as convenient for use on the move as other makes and models but it is light enough weighing in at just over 1 kilo.
At the top of the price scale the ACER AOD150-1BW 6C Netbook costs £329, weighs only 1.2 kilos and offers a whopping 7 hours of battery life making it a super portable computer for a professional on the move. The display screen is slightly larger at 10cm, and should omit the need for excessive sideways scrolling. This model also has a higher processor cache than the Toshiba and Asus so it should run smoother and quicker. It also includes Intel 945GM shared graphics – an economical solution that borrows your computers main memory to use for graphics.
In the world of technology smaller is considered better, but ensure that you don’t choose a machine that is so small that it is too difficult and fiddly to use. As with most things there will have to be a compromise between size, functionality and usability.

ASUS generated a lot of buzz with its Eee-branded line of products, starting with the Eee PC netbook and is responsible for introducing the netbook to the PC market as an affordable and simple laptop solution for students.
A netbook (a portmanteau of the words Internet and notebook) is a small portable laptop computer designed for wireless communication and access to the Internet.
By late 2008, netbooks had begun to take market share away from laptops. It is estimated that almost thirty times more netbooks were sold in 2008 (11.4 mn) than in 2007 (400,000).
After the release of the ASUS’s Eee PC, almost every major PC vendor HP, Sony, MSI, Toshiba, Acer, Dell have released competing models. Some companies design them in different directions away from the original Eee PC and they got bigger, more powerful, more expensive, and have even become luxury items. Furthermore, Windows XP has dominated over Linux as the installed operating system.
ASUS range
1. ASUS Eee PC 701 4G: with Xandros version of Linux, had a 4GB solid state drive, a small 7in screen, 512MB of RAM and an Intel Celeron M CPU, also available in a variety of color at a cost of $349.
2. ASUS Eee PC 900: With slightly bigger 8.9in screen, but it has more storage and RAM and is available with either or operating system versions.

A type of wireless communication that is most familiar to mobile phones users. It’s called ‘cellular’ because the system uses many base stations to divide a service area into multiple ‘cells’. Cellular calls are transferred from base station to base station as a user travels from cell to cell. The basic concept of cellular phones began in 1947, when researchers looked at crude mobile (car) phones and realized that by using small cells (range of service area) with frequency reuse they could increase the traffic capacity of mobile phones substantially. However at that time, the technology to do so was nonexistent.
Anything to do with broadcasting and sending a radio or television message out over the airwaves comes under Federal Communications Commission (FCC) regulation. A cell phone is a type of two-way radio. In 1947, AT&T proposed that the FCC allocate a large number of radio-spectrum frequencies so that widespread mobile telephone service would become feasible and AT&T would have an incentive to research the new technology. We can partially blame the FCC for the gap between the initial concept of cellular service and its availability to the public. The FCC decided to limit the amount of frequencies available in 1947, the limits made only twenty-three phone conversations possible simultaneously in the same service area – not a market incentive for research.
The inventor of the first modern portable handset is Dr Martin Cooper, who was the general manager for the systems division at Motorola at that time. In 1973, Dr Cooper made the first call on a portable cell phone. He called his rival Joel Engel, head of research at Bell Labs, to give him the latest news on how the competition between them was turning out. The picture above represents him and his first mobile phone. The first commercial handheld cellular phone was launched by Motorola.
Mobile phones have influenced the human life from a variety of ways. The Mobile Technology has become inevitable part of our today’s lifestyle. It can be claimed sole responsible undoubtedly, for revolutionizing our ways of living, thinking, working, performing as well as interacting with the society. There is a major role of Telecommunication in general and Mobile Telecom in particular, in making the entire world as “Global Village.
Mobile phones often have features beyond sending text messages and making voice calls, including Internet browsing, music (MP3) playback, memo recording, personal organizer functions, e-mail, instant messaging, built-in cameras and camcorders, ring tones, games, radio, Push-to-Talk (PTT), infrared and Bluetooth connectivity, call registers, ability to watch streaming video or download video for later viewing, video calling and serving as a wireless modem for a PC, and soon will also serve as a console of sorts to online games and other high quality games. The total value of mobile data services exceeds the value of paid services on the Internet, and was worth 31 billion dollars in 2006. The largest categories of mobile services are music, picture downloads, video gaming, adult entertainment, gambling, video/TV.
Currently the world’s largest manufacturer of mobiles is Nokia, with a global device market share of approximately 40% in 2008. Other major mobile phone manufacturers (in order of market share) include Samsung (14%), Motorola (14%), Sony Ericsson (9%) and LG (7%). These manufacturers account for over 80% of all mobile phones sold and produce phones for sale in most countries.

Bluetooth technology is a type of the wireless technology that eliminates the need for the number of inconvenient cables and devices that are used to connect the computers, mobile phones, digital cameras, handheld devices and new digital appliances. Bluetooth enables the users to connect to a wide variety of telecommunication and computing devices easily, without cables.
It makes rapid ad hoc connections, automatic unconscious connections between two or more digital devices. Bluetooth provides the opportunity of using the mobile data in different applications. Bluetooth makes wireless communication between the two devices in a localized area of a room of office or home very easily. Bluetooth technology uses radio-based links and all the connections between the devices and invisible and instantaneous.
By Bluetooth technology your laptop can send print request to a printer in your next room. Bluetooth is actually a standard for wireless communication between the devices in a relatively small area and it is therefore works fine in the personal area network (pan) using radio frequency.
Any two devices that follow the Bluetooth standard can communicate with each other. A number of the Bluetooth devices like digital camera, mobile phone and handheld pc can form a network. You can send emails to your mobile phones from your laptop without any physical connect between your laptop and your mobile phones.
Features of Bluetooth technology
Bluetooth technology uses radio waves for communication in 2.4 GHz
It supports multi point communication not just point to point.
Bluetooth works in a small area of 10-15 meters.
Bluetooth offers speed of 1-2 mbps.
Bluetooth chipsets are less expensive though more expensive than IrDA.
How Bluetooth technology works
Bluetooth is a high speed wireless link technology that uses the radio waves. It is designed to connect the mobile phones, laptops, hand held devices and portable equipments with almost no work by the end users. Unlike infrared Bluetooth does not require line of sight between the connecting units. Bluetooth technology is a modified form of the current wireless LAN technology and it’s more acceptable for its relative small size and low cost.
The current circuits are contained on a circuit board of 0.9 cm square and a much smaller single chip version is in development and soon it will be in use. The cost of the Bluetooth device is expected to fall rapidly. Bluetooth chip has to be equipped in many devices. In Bluetooth technology, small and inexpensive transceivers have been placed in the digital devices. The radio waves operate at 2.45 GHZ band on the Bluetooth devices. Bluetooth supports the data speed up to 721 Kbps and 3 voice channels. The Bluetooth chip can either be built into the devices or it can be uses as an adapter. In computer it can be used with the USB port. Each Bluetooth device has a 48 bit address from the IEEE 802 standards and the Bluetooth connections can be either point to point or multi point. Bluetooth range is 10 meter but it can be extended up to 100 meters by increasing the power.
Bluetooth devices are protected from the external interference because they change their frequency up to 1600 times in a second. Bluetooth radio technology provides the bridge between the existing data network. Bluetooth guarantees security at the bit level and the authentication is controlled by the end user by using 128 bit key.

With every passing month, it seems that more electronic devices are touted as being Bluetooth enabled. And, while many people are excited about the advent of its new products, others are left scratching their heads wondering, “What is Bluetooth?”
Bluetooth mobile wireless technology has become one of the leading technologies for wireless communication world wide. The reason it has become so popular around the globe, in just a few short years since its introduction, is because it allows phones, computers, PDAs and other electronic devices to easily communicate with the other enabled devices nearby. The range of its networking is limited to a short range of about 30 feet.
Bluetooth utilizes radio waves, in the non-licensed range of 2.4 Gigahertz. This system has been designed with the intention of providing a secure and an inexpensive way to connect with and exchange information between other devices alike, all without the need of wires.
What is Bluetooth technology mainly used for? The Bluetooth mobile wireless technology has quickly become the standard for all wireless methods of communication. It can now be found integrated into the latest and most popular models of handheld computers, laptops, PDAs, printers and headsets, not to mention cellular phones. Manufacturers are finding more and more products to add the technology to, as the demand for this enhancement increases.
In addition to the Bluetooth wireless phone models, which are probably the most prevalent type of devices on the market, you can now also find its headphones and speakers. It is expected that other Bluetooth wireless audio and video products will continue to be brought to the marketplace.
With this type of advancement, it is conceivable that some day the only wires you will need to tame, will be the power cords that some of these devices will need for their power supply. That would be a welcomed change from the tangles of cords and wires that are common in home offices and entertainment areas.
One of the best features, is that all its enabled devices function on a standard protocol. This means that all transmission of data and voice signals between two of its devices, even if they are produced by different manufacturers, is straightforward and simple to implement.
It was the need for a standardized communication convention that prompted the development of Bluetooth technology. Rather than the need for each manufacturer to establish their own standards, and thereby limit the connectivity to other devices made by the same company, they can simply implement the Bluetooth wireless technology networking standard. This simple approach has made it a global solution used by all manufacturers and benefiting the end-user significantly.
Some of the other advantages of Bluetooth are: data transfers that are fast; communication with other devices alike that are not in a direct line of sight (as required by the infra-red protocol); inexpensive circuitry and components; the ability to transmit both data and voice concurrently.
This technology has been on the market for almost a decade. One of the reasons it is relatively inexpensive and widely used is because the original developer, Ericsson, has made the specifications royalty-free so manufacturers do not have to pay to implement the technology in their devices.
