Take a Bite Out of Vacation Blues With Bluetooth
Have you ever tried to find your way across town (or across the country) using an old-fashioned road map? The only thing trickier than deciphering the directions, is figuring out how to re-fold the map! Today's travelers are finding it much easier to find their way with GPS receivers, PDA devices and Bluetooth technology.
Every since GPS became widely available on the market the need for maps and large navigational devices became redundant. Today's traveler can refer to the tiny computer screen on the GPS receiver to find exactly where to go.
A GPS receiver is a small electronic device that can actually calculate your precise location on earth. The GPS is able to decode signals sent from satellites in outer space, and use those signals to tell you where you are at any given time. When combined with specialized software and electronics, the GPS is able to pinpoint an exact location on a map, and give you instructions on how to get there. This fascinating technology becomes even more incredible when you discover that it can be had for a relatively small price.
When paired with other mobile communication devices, such as PDAs, a GPS unit becomes even more useful. A PDA is a popular consumer communication product that combines a cellular phone with an organizer and Internet access. PDAs have hard drive space that makes them the perfect companions to GPS units. This hard drive space can be used for storing maps, and the colored screens are ideal for displaying maps. With their small size, it's easy to see why so many travelers choose to use PDAs over laptop computers and other bulkier options.
There are certain drawbacks to using GPS receivers with PDAs. In order to connect the two units, some people use conventional USB wires, while others choose a CompactFlash (CF) CARD. Either option means that both the GPS and PDA must be kept together. But, wires are inconvenient and limit the overall usability of the navigation device, while a CF card simply adds more bulk to the already cumbersome equipment. For these reasons, many travelers see Bluetooth technology as the perfect answer.
Bluetooth Solution
Bluetooth technology is widely known as the standard for modern wireless communication. This system allows two electronic devices, such as a GPS and PDA, to send and receive signals, transfer data and "communicate" with each other. The information is shared without wires.
GPS Receivers Using Bluetooth
A Bluetooth GPS receiver is an electronic device that uses wireless technology (namely, Bluetooth electronics) to transmit GPS data. The data is transmitted to a second wireless device, such as a PDA, that is capable of handling the technology. For example, a GPS receiver can wirelessly transmit data to a PDA handset, but only if they are both enabled with Bluetooth capabilities.
In addition to the ease and convenience of avoiding bulky CompactFlash cards and messy wires, there are other benefits to using Bluetooth technology with your GPS/PDA combination:
Flexible Freedom
Without wires to tie them down, you are free to position your GPS receiver and PDA device where it's most convenient for you. Many travelers choose to place the GPS on the dashboard, allowing it to maintain a clear connection with satellites in the sky. The PDA is best mounted right in front of the driver, where he or she can clearly see the directions on the screen. With Bluetooth technology there are no wires to limit the convenience or obstruct your view of the screen.
CompactFlash Slot
If you are using Bluetooth GPS and PDA, you'll have no need to a CompactFlash. In this case, you can use the empty CompactFlash slot as a storage area for maps and other software required to optimize your GPS navigation.
There are other benefits to using GPS equipment. Many Bluetooth GPS receivers offer companion features, such as a "Points of Interest" (POI) database, route re-calculation function and pre-stored maps.
Learn more about the benefits of using GPS and PDA on your next trip, and then shop around for the models that best suit your needs. You'll spend less time trying to find your way, and more time having fun with your family.
