Piconet

from Wikipedia, the free encyclopedia

A piconet is a personal area network of end devices that are connected via Bluetooth . The name is made up of the words "pico" (Romansh: small ) and " network ".

A piconet occurs when at least two devices such as B. connect a notebook and a mobile phone . A point-to-point and point-to-multipoint connection is possible between these devices , with one device acting as the “ master ” and the other as the “ slave ”. The devices are identified by the AMA (ActiveMemberAddress, 3 bit). In addition, participating devices can also be in a passive mode, either “ Standby ” or “Parked”, and are identified using the PMA (PassiveMemberAddress, 8 Bit). Thanks to the 8-bit address, up to approx. 200 (theoretically 2 8 = 256) Bluetooth devices can remain in standby mode. When several piconets are combined, one speaks of a scatternet .
