The Bluetooth Solution

The Bluetooth Solution

The technology of Bluetooth will take small area networking to the next level by removing the need for user intervention and help keep transmission power very low to preserve battery power. Each transmission signal to and from your cellular phone will use just 1 mw of power, giving you plenty of space on your battery to talk.

Bluetooth is a networking standard that will work on two levels: 1. It will provide agreement at the physical level, as Bluetooth is a radio frequency standard. 2. It will provide agreement at the level of protocol, where products will have to agree on when bits are sent, how many are sent, and how the parties in conversation can be sure the message recieved is the same one that was sent.

The major draws to Bluetooth is the fact that it's wireless, inexpensive, and automatic. There are other ways to get around wires, including infrared. Infrared uses light waves of a lower frequency than the human eye can, and is normally used in television remote controls.

The technology of Bluetooth is intended to get around the problems that normally come with infrared systems. The 1.0 older standard of Bluetooth has a max transfer speed of 1 MB a second, while the 2.0 Bluetooth standard can manage up to 3.0 MB a second. To make things better, 2.0 is compatible with 1.0 devices.

As a solution to wireless, Bluetooth will eliminate the need for messy cords, keeping everything nice and neat. It's perfect for those who like to talk on cell phones, as you no longer need to hold the phone next to your ear - which is great for those who travel a lot.

Bluetooth Basics

Bluetooth Basics

The technology of Bluetooth wireless is a short range communications method intended to replace the cables that connect portable or fixed devices while maintaining the highest levels of security.

The key features offered by Bluetooth include low power and low cost. The specification in Bluetooth defines a uniform structure for a wide range of devices to communicate and connect with one another.

The technology behind Bluetooth has achieved global satisfaction such as enabled devices, almost everywhere in the world. Bluetooth devices will connect and communicate without wires through short range and networks known as piconets.

Each device will simultaneously communicate with up to seven other devices within a single piconet, meaning that each device can also belong to several piconets simultaneously. The piconets are dynamically established as Bluetooth enabled devices enter and leave the proximity of radio.

A fundamental to Bluetooth strength is the ability to handle both data and voice transmissions simultaneously. This will enable users to enjoy varieties of innovative solutions such as hands free talking, printing and fax capabilities, and other applications.

Specifications Unlike other standards of wireless, the Bluetooth specification gives product developers both a link layer and application layer definitions, which will help support data and voice applications.

Spectrum The Bluetooth technology operates in the industrial and scientific band at 2.4 to 2.485 GHz, using a spread spectrum, frequency hopping signal.

Interference The adaptive frequency hopping of Bluetooth technology was designed to reduce interference between wireless technologies that share the 2.4 GHz spectrum. Adaptive frequency hopping (AFH) works well within the spectrum to take full advantage of the frequency available.

AFH hopping allows for more efficient transmission within the spectrum, which provides users with greater performance even if they are using other technologies along with Bluetooth.

Travelling Is Easier With A Pda And A Bluetooth Receiver

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 one?s 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 reciver.

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 capable PDAs offer 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 won?t need to use Bluetooth?s 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.
