…which links mobile information appliances
Bluetooth is a Radio Technology which can be used to seamlessly communicate between mobile information appliances or between mobile and fixed information appliances.
It improves your ability to keep in touch with the world around you.
It makes your current information appliances convenient and hassle-free.
And it allows you and me to interact and exchange ideas and information in a totally ad hoc manner.

COMMUNICATION COMPONENTS AND MODULES
Radios are symmetric (same radio can be master or slave)
Piconet
Master can connect to 7 active and 200+ parked slaves per piconet
Each piconet has maximum capacity (1 shared Mbps)
Unique hopping pattern/ID per piconet
Scatternet
Radios can share piconets!
