High Quality Content by WIKIPEDIA articles! The original Piconet was a networking type used on RM Nimbus computers. These days, a piconet is an ad-hoc computer network linking a user group of devices using Bluetooth technology protocols to allow one master device to interconnect with up to seven active slave devices (because a three-bit MAC address is used). Up to 255 further slave devices can be inactive, or parked, which the master device can bring into active status at any time. A piconet typically has a range of about 200 m and a transfer rate between about 200 and 2100 kbit/s at the application, depending on whether synchronous or asynchronous connection is used.
