Bluetooth GPS and PDA Explained
By: Rainer Cassell
Traveling used to mean packing along detailed and illegible maps and compasses of questionable reliability. Given the number of times travelers had to stop and pull over to check a map, it's a wonder that we ever traveled at all! These days, modern travelers can easily find their way with a small hand held wonder called a GPS receiver.
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.
GPS receivers become even more useful and convenient when paired with other mobile devices. A PDA is a popular consumer product that is easily used along with a GPS. PDAs have hard drive space to allow for map storage and colored screens to display maps, making them ideal technological GPS partners. When one takes into account the small size and weight of a compact PDA as compared to options such as laptop computers, it's easy to see why PDAs are the choice of today's tech-savvy travelers.
Integration poses a problem with using a PDA with a GPS receiver. Most PDAs are connected to GPS receivers with either a CompactFlash (CF) card, or conventional USB wires. The size of the GPS, added to the size of the PDA, plus a CF can create a bulky and cumbersome system. Using wires, on the other hand, can be inconvenient and actually limit the usability of your navigation device. Many people are finding the best solution to the problem is through Bluetooth technology.
Rescued by Bluetooth
Bluetooth wireless technology has become the open standard for wireless communication. Using Bluetooth technology, two electronic devices are able to communicate with each other, sending a receiving signals and transferring data, from up to ten meters away. The beauty of this technology is that the information is transmitted completely wire-free.
Bluetooth GPS Receivers
Bluetooth GPS receivers are electronic devices that use wireless technology or Bluetooth electronics to transmit GPS data. This data is transmitted to a second mobile device that is capable of handling the same technology. In other words, a Bluetooth GPS receiver can send data to a PDA, provided that PDA is also equipped with built-in Bluetooth capabilities.
There are many advantages to using Bluetooth GPS receivers with compatible PDAs for data transmission, rather than using CompactFlash or USB wires:
Wireless Convenience
Many drivers prefer to have the GPS mounted securely positioned, while keeping the PDA where it can be clearly viewed. Bluetooth allows this wire-free convenience. You are able to position your Bluetooth GPS receiver in a spot where it can clearly pick up signals from the sky, while your PDA is mounted on the dashboard in front of you. There are no wires to hamper your driving or obstruct your view.
Added Storage
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.
Many travelers are able to get even greater benefits from their GPS receivers. Some units come with handy companion features like pre-stored maps, route re-calculation (perfect in the case of road detours) and POI (points of interest) databases that show you popular tourist attractions en route.
So, whether your travels are taking you to the next neighborhood or another country, don't leave home without your GPS and PDA bundled with Bluetooth technology.
