Mobile Bluetooth GPS Turns PDA Into GPS Navigator

Sphere: Related Content
Just about anyone with a home computer and a PDA can turn their personal data assistant into a mobile Bluetooth GPS unit with a few simple mouse clicks. Additionally, by using this wireless technology, the connection can be made without any type of wiring harness or hard docking connection between the Bluetooth receiver and the PDA. By placing the mobile Bluetooth GPS unit into its docking cradle connected to a computer, the information and trip planning can be downloaded into the PDA turning it into a navigational device.

One the main advantages of using a mobile Bluetooth GPS unit is that it can be carried with the user no matter what vehicle they are using and when walking, they only need to carry their PDA, leaving the pockets empty of often-heavier and larger GPS receivers. With mapping information retained on different memory storage cards, several different maps can be available for use in the mobile Bluetooth GPS unit.

However, a PDA is not the only device capable of being used as a mobile Bluetooth GPS device. There are also make units for Bluetooth GPS for pocket PC units, that can turn more advanced handheld computers and laptops into mobile Bluetooth GPS devices. This can greatly enhance the portability of any GPS receiver, provided the unit has Bluetooth capabilities and is properly married to the GPS receiver.

Wireless Internet Access Enhances GPS Portability

With the number of wireless internet access points continuously growing, the use of mobile Bluetooth GPS systems is also improving. With many PDAs and laptop computers having installed wireless internet access capabilities, they can be turned into a mobile Bluetooth GPS unit simply by connecting through one of several thousand WiFi points located throughout the country.

Some hot spots, as they are commonly called, may charge for access while some locations offer the access free to their customers. No matter where a person is traveling, they should be able to easily find a wireless access point with which to connect to the internet, and download information about unfamiliar locations into their PDA or laptop and add maps to their mobile Bluetooth GPS devices.

For the most part, many of the units can automatically detect the presence of an incoming signal from a mobile Bluetooth GPS transmitter, but some may require software to appropriately establish a connection between the two devices. The use of Bluetooth technology is becoming more popular with its ability to work between different devices from various manufacturers.

How Bluetooth Wireless Works

Sphere: Related Content
The world of communication has changed greatly in a short amount of time. Thanks to the revolutionary world of cell phones, the world can be connected in an instant. However, cell phones without a wireless device can prove to be deadly if you are driving and talking at the same time. Luckily Bluetooth wireless items have come along, and they help to ensure that the world of communication gets smaller and smaller all the time. Understanding how a wireless Bluetooth device actually works though, is something that most of us do not think of when using one. But, as with any other type of gadget, understanding how it works can make us a better user.

Basic Bluetooth Wireless Information

The first thing to understand about the Bluetooth wireless device is that it uses a radio frequency to actually work. If you have a child then you also have another device that uses the same type of frequency. A baby monitor acts just like a Bluetooth wireless device. The actual radio waves that work with a wireless Bluetooth device are very low and can actually work up to thirty two feet away from the device, such as a cell phone that it is compatible with when working. The good thing about using a Bluetooth wireless headset is that because the Bluetooth wireless device does what is known as frequency hopping, rarely will two or more devices interfere with each other. That is why so many people can drive on the same road and not hear each other’s conversation. Granted, though, sometimes this may actually occur, but it is really a rarity.

Since this may be a draw back for some to purchase a Bluetooth wireless device, one may be wondering how often a Bluetooth wireless device actually does change it frequency. The answer is a whopping one thousand six hundred a second. That is enough to make anyone’s head do a double take. A person who is reluctant to purchase a Bluetooth wireless device on the grounds that they will hear others should really put their fears at ease.

Owning and operating a Bluetooth wireless device is easy once you understand how they work. Just as with other devices including a garage door opener and a baby monitor, a Bluetooth wireless device uses radio frequency. This is a plus for those who may be pondering whether or not to purchase one. Bluetooth wireless devices have come a long way, and they help to keep us safe while we drive, so go ahead and buy one. It may save your life.

What Is Bluetooth Technology? A Really Fancy Radio

Sphere: Related Content
You know the expression, "The more things change -- the more things stay the same?" That certainly applies to what Bluetooth technology is. It works very much like that crazy little high tech device we call a radio. When a station broadcasts on radio waves, a radio (designed to pick up those waves) makes the inaudible signals audible. You could stand right next to a radio station and not know what song they were playing unless you had a radio with you.

Frequency Hopping In Timeslots

So, what is Bluetooth technology? It's a radio for wireless devices. It's also a translator, making, say, phones with Bluetooth technology able to download information to your PC or Laser printer. It only works for short distances, but it does keep your hands free. If you do a lot of driving for your job, then what is Bluetooth technology for you? A lifeline!

The actual science to describe every detail of what Bluetooth technology is would take up a book in and of itself. This will just be a summary, but it will still give you a good idea of what it's all about. Technically, the name of the means a Bluetooth device uses to do the magic it does is called "frequency hopping in timeslots".

Now, what does that mean? It means a Bluetooth device keeps changing from one radio frequency to another after a certain "packet" of data is received. This packet of data could be a unit or time, an email or small bits of information. Data or information is sent out on a global radio frequency. A computer chip in the Bluetooth device picks it up and acknowledges receiving it and then switches to another frequency. The gizmo sending the information also changes to that frequency. In case you're wondering, there are a lot of frequencies a Bluetooth can pick up.
