1. The System
1.1 Bluetooth
Bluetooth is an open specification for seamless wireless short-range communications of data and voice between both
mobile and stationary devices. For instance, the standard specifies how mobile phones, computers and PDAs interconnect
with each other and with computers or with office or home phones.
The first generation of the Bluetooth standard permits the exchange of data up to a rate of 1 Mbps per second, even
in areas with much electromagnetic disturbance. It transmits and receives via a short-range radio link using a globally
defined frequency band (2.4 GHz ISM band).
It has been specifically designed as a low cost and low power radio technology, which is particularly suited to short range
Personal Area Network (PAN) applications. It is the design focus on low cost, low size and low power which distinguishes
it from the IEEE 802.11 wireless LAN technology. For more information please see the Internet addresses
