The technology of Blue Tooth 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. A fundamental to 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. A Blue Tooth device that operates in master mode can communicate with up to seven devices that are set in slave mode. To each of the slaves, the master device will send its own unique address and the value of its own internal clock. The information sent is then used to calculate the frequency hop sequences. As a replacement for cable technology, it is usually battery powered, such as wireless mice and battery powered cell phones. To conserve the power, most devices operate in low power. This helps to give a range of around 5 - 10 meters. It is a high speed, low powered wireless link technology that's designed to connect phones or other portable equipment together with little to no work required by the user. Unlike infrared, it does not require line of site positioning to work. What is important, is the fact that Blue Tooth devices will not drain battery life. The specification targets power consumption of the device, limiting the drain on the battery. The radio chip will consume only 0.3mA in stand by mode, which is less than 5% of the power that standard phones use. And will also guarantee security at the bit level. The authentication is controlled by the user via a 128 bit key. The radio signals can be coded with anything up to 128 bit. With the frequency hopping, it is already very hard to listen into. It has a lot to offer with an increasingly difficult market place. And helps to bring with it the promise of freedom from the cables and simplicity in networking that has yet to be matched by Local Area Network. In the key marketplace, of wireless and handheld devices, the closest competitor to Blue Tooth is infrared. Infrared holds many key features, although the line of sight it provides does not go through walls or through obstacles like that of the technology. There are other ways of connecting wireless devices. One example of such is the infrared. Infrared allows low frequency light waves to transmit signals to another component. This technology is easy to create and the cost of putting the infrared device into a system is rather low. Infrared technology is a one to one process. Due to the limitation, you may only send signals from one device to another, similar to a television set and remote control. You can only transmit signals between the two although not with a separate system. Your Mac also has the ability to use technology to communicate with your Palm Operating System handheld. This way, you can perform a Hot Sync operation without using any cables. You can also send your business card or calendar events directly to handheld using the technology. The implementation of Blue Tooth by Apple is the latest in a series of moves that have caused great shift in the computer industry. The technology 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, giving you plenty of space on your battery to talk. As a solution to wireless, will eliminate the need for messy cords, keeping everything nice and neat. It is 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. These days, all communication technology faces the issue of privacy and identity theft. Almost everyone knows that email services and networks require security. What users of need to realize is that it also requires security measures as well. The good news for users is that the security scares, like most scares, are normally over dramatized and blown entirely out of proportion. The truth being told, these issues are easy to manage, with various measures already in place to provide security.
