Forming a Piconet (I) • Initially, devices know only about themselves • No synchronization • Everyone monitors in standby mode (performs inquiry or page scan for 10 ms every 1.28 seconds • Power consumption in standby mode is reduced by over 98% • All devices have the capability of serving as master or slave D E F A H C B G • Devices in this illustration are in the same mode but are not synchronized or coordinated - listening at different times and on different frequencies
