Bluetooth technology works by transmitting low-powered radio signals in the 2.4 GHz range. Bluetooth wireless technology can penetrate solid objects, and unlike other technologies, it is omni-directional. This means that the technology does not require line-of sight positioning of connected devices and can communicate with other devices and extend beyond doors, walls and even different levels of a building. As long as the devices are in range, they can interact. This enables us to setup a personal-area network (PAN), which translates into the ability to own devices that can detect and interact with one another as they come within range of one another.
How close do they need to be you ask? That depends on the class of the Bluetooth device. There are two classes of Bluetooth. The first class, the weaker of the two, can transmit signals over a 33 foot range. The second class, the stronger of the two, can send and receive signals as far as 328 feet away.
In most cases you truly only need to be 10 to 20 feet or so away from these devices, as is the case with bluetooth printers. For the typical home user, you will likely be in the room with the printer or in a room close by to where the printer resides. The advantage of these devices is that you can print from far away sans wires. This technology is at the heart of innovations such as wireless printers and mobile printers. If you are on the go, who wants to lug with them a nest of wires to connect their printer to their laptop - Heaven forbid you forget to bring the wires and then are left up a creek without a paddle. Bluetooth allows the laptop and printer to effortlessly communicate with one another, assuming Bluetooth is built into both devices, or if your laptop has a Bluetooth card adapter. Luckily this feature comes standard on today's generation of devices.
A great example of a Bluetooth printer is the HP Photosmart C5580 All in One Inkjet Printer. This printer, like most hp wireless printers, can print directly from Bluetooth devices and can print up to 34 pages per minute. The device also copies, scans and includes features such as its automatic paper-type sensing.
The best photo printers come with Bluetooth technology so you can wirelessly, and rapidly, communicate and send photos from your digital camera to your wireless printer. Bluetooth can transmit data at a rate of up to 3 Mbps, which is very fast. Bluetooth enables you to quickly and efficiently send digital photos to your printer, where you can then instantly make photo prints. In addition to HP printers, Canon's line of canon pixma printers is also a popular choice for photo printers. The Canon PIXMA MP610 Photo Printer comes equipped with Bluetooth technology, a 2.5" TFT previewing display and spectacular 4800 x 9600 color dpi results.
If there's one drawback to Bluetooth it is the level of security. Because Bluetooth devices can connect to networks so easily, then it might be possible for someone to eavesdrop on you using another Bluetooth device. Bluetooth security is in the hands of electronics manufacturers who can produce devices that are secure or unsecure. So shop wisely and use the best, most trustworthy of brands.
