Infrared And Bluetooth: Connecting Things Easier
By Robert Thatcher
With different electrical devices produced everyday, the problem of connecting things is becoming more and more complex. The system that comprises the computers and other electronic devices makes use of varieties of connecting wires, cables and the likes. These parts communicate trough light beams, lasers, radio signals and infrared. However, the problem with this devices and technologies is often the connection between each component. Thus, most systems are not used to their full extent due to complexities.
To simplify things, a solution was created to streamline the process of connections - bluetooth.
Bluetooth is wireless and automatic and offers users with varieties of excellent features that has recreated the art of connection. It has revolutionized the standard method of connecting things that virtually anything can be connected on a single system. From computers to mobile phones and from keyboards to headphones by means of wireless, automatic and inexpensive connection.
Other than the bluetooth technology, there are other ways of connecting things. Take for example the infrared or IR. It allows low frequency light waves which the eye can no longer interpret to transmit signals to another component. The technology is easy to create and cost of incorporating the IR device into a system is in barest minimum. Yet it has limited operations that seldom obstructs the process of connection.
Infrared technology is one to one process. Due to this limitation, you may only send signals from one component to another, like the case of the television set and the remote control. The same is true between laptops and desktops. You may only transmit signals between the two but not with another separate system, say a PDA through simultaneous actions.
It also works only on the line of sight principle wherein one has to point the infrared device directly to the host system to achieve a desirable result.
In spite of the fact that these two natures of infrared technology are obstacles to acquiring results, these same qualities have worked in advantage to connection. Because infrared devices need to be lined up directly on opposing locations, too little interference occurs between transmitters and receivers. The one to one principle on the other hand is designed to transmit signals only to the original recipient. Given that there are varieties of infrared recipients in a location, the intended recipient alone will receive the signal coming from a transmitter.
However, technology was not contented with what infrared offers. They resolved these limitations through creating the bluetooth solution.
Bluetooth technology works by transmitting signals via low frequency radio signals. The path of communication is approximately working on 2.45 gigahertz. The same frequency band is utilized in ISM devices.
The design of the technology was such that it has created a new system that does not interfere with the other devices that make use of the same frequency band (e.g. ISM). One way of doing this is the programming of the bluetooth technology to only transmit signals that has 1 milliwatt or less. Beyond this, other systems may be affected. By comparison, cell phones and other mobile devices send signals at a rate of 3 milliwatts and more.
The standard range of the bluetooth is around ten meters. This lessens the possibility that interference between device may occur. With this low transmission, it is still possible for the user to transmit bluetooth signals between obstructing walls.
Bluetooth in many ways have contributed much in connecting individual systems without being bothered by the bulk of the cables and wires.

Comments About Bluetooth Technology
If one is on the go and has multiple devices or switches between them often, the new iGo chargers have interchangeable tips to accommodate most models of mobile phones. Whether one needs a car, portable battery or wall charger, iGo can get multiple devices going with the same charger.

Adtec is claiming their new Bluetooth headset to be worlds smallest at only .9x.86x1.2 inches, weighing only .01 ounces or 5 grams. That�s pretty darn tiny. My two biggest concerns is how good is the quality and the company�s optimistic claim of 3-hours talk-time or 100 hours of standby.

Travelling Is Easier With A Pda And A Bluetooth Receiver
By Abby Johnson
Traveling is always easier if you take as little with you as humanly possible. It's always the intention while traveling to carry only to what is most necessary. This is not always an obtainable goal, especially when you are venturing into parts unknown. In addition to the usual essentials, a sizable map and navigational equipment become necessary.
With the unveiling of GPS technology, traveling with maps and huge navigational devices becomes unneeded; a traveler need only carry a GPS receiver. A GPS receiver determines ones exact position on earth by deciphering the information it receives from GPS satellites. With the assistance of other electronic devices, the GPS receiver will precisely determine your correct location on a map.
For even more even more functions and ease of use, GPS receivers can be used with other mobile devices. The PDA is one of the most frequently used mobile products for this purpose. PDAs make the perfect partner to the GPS receiver because of their unique features, such as a colored screen to display maps and hard drive space for map storage. And PDAs are light compared to other mobile devices such as notebook computers.
There is a problem with using a PDA with a GPS device, however. They do not always integrate well. GPS receivers are normally connected to PDAs using a CompactFlash (CF) card or USB wires. Because some GPS receivers are quite large, attaching it to your PDA using CF can make it too large. Using the USB wires, however, can make your GPS receiver difficult to use and limit its usefulness.
So what could be the solution to this problem? A bluetooth GPS Receiver.
The Bluetooth Solution
Bluetooth wireless technology is the open standard for wireless communication. As long as the two electronic devices are with 10 meters of each other, Bluetooth technology will allow them to send and receive signals and transfer data. No wires are necessary.
Bluetooth GPS Recevier
The Bluetooth GPS receiver is simply a receiver that uses the Bluetooth technology and electronics to transmit GPS data to a mobile device. However, they must share the same technology. For example, if a Bluetooth GPS receiver will be used with a PDA, the PDA must have built-in Bluetooth technology.
The Bluetooth GPS receivers used with the bluetooth PDA offers many advantages over an ordinary GPS unit, which is connected to the PDA using CompactFlash or USB wires. These advantages include the ability to use wireless connections between the devices. Without wires to limit positioning between the Bluetooth GPS receiver and the PDA, you can place the two devices at their most advantageous locations. For example, if you are using your Bluetooth GPS receiver in your car, you can place the device where it has a clear view of the sky. Then you can place your PDA on your dashboard and have optimum screen visibility. Because the wires are not used to connect the two devices, their positioning will not hamper your driving. Also, because you wont need to use Bluetooths CompactFlash slot, you can use it for other things, such as storing maps or software to optimize the GPS navigation.
Aside from these two advantages, the Bluetooth GPS receiver units have other features, although most of them are brand or unit specific. Generally, Bluetooth GPS receiver units now have pre-stored US maps, point-of-interest (POI databases and route recalculation functions.

Thoughts About Bluetooth
While most of the US is just getting their first glimpse of the Neonode N2, we've got the Neonode N2.5 for you dear readers. We were assured that this engineering prototype features a heftier battery to offset complaints raised by N2 owners. The other complaint -- lack of 3G data -- is also solved. It will also feature A2DP-enabled Bluetooth 2.1 (yes, 2.1) when its ships (no time specified) and a big fat 3G radio of unspecified type. Thing is, this time, the N2.5 is specifically targeted at the US market with Neonde already starting to sort through the carrier quagmire in order to bring it to market. WiFi? Maybe, that all depends upon the carrier's demands. Other than those changes, it features the same UI and touch screen technology of the tiny N2 which is fine by us. The only question now is how consumers react to it's new chubby profile.

Gear4's latest Bluetooth speakers pack a surprisingly decent sound for such a small unit with only 8W speakers. The beauty of this device is that it allows you to beam music from any Bluetooth-enabled gizmo straight to the speakers from a distance of up to 10 metres away from the unit. And because it's wireless, there's less chance of New Year's revellers tripping over trailing cables while dancing to Auld Lang Syne.
