What Does Piconet Mean?
A piconet is a network of devices connected using Bluetooth technology. The network ranges from two to eight connected devices. When a network is established, one device takes the role of the master while all the other devices act as slaves.
Piconet gets its name from the word "pico", which means very small. This very small network is so called because the number is limited to seven devices, plus the master, which limits network and data sharing capability. Data transfer rates vary from 200 to 2,100 kbps at the application.
A piconet is sometimes called a personal area network (PAN) because the range of optimal operation for Bluetooth is 10 meters, about the size of a living room.
