1. Output Power and Channel Separation of a Bluetooth Device
in the Different Operating Modes
The different operating modes (data-mode, acquisition-mode) of a
Bluetooth device don't influence the output power and the channel
spacing. There is only one transmitter, which is driven by identical
input parameters concerning these t wo parameters. Only a d ifferent
hopping sequence will be used. For this reason, t he RF parameters
in one op-mode are sufficient.
2. Frequency Range of a Bluetooth Device
The maximum frequenc y of the de vice is 2402 MHz - 2 480 MHz. T his
is according the Bluetooth Core Specification V 1.1.
3. Co-Ordination of the Hopping Sequence in Data Mode to
Avoid Simultaneous Occupancy by Multiple Transmitters
Bluetooth units, which want to communicate with other units, must be
organized in a structure called piconet. This piconet consist of
maximum 8 Bluetoot h units. One unit is the m aster the other seven
are the slaves. The m aster co- ordinates f requenc y occupation in this
piconet for all units . As the master hop sequence is der ived from it's
BD address which is unique for every Bluetooth device, additional
masters intend ing to esta blish new piconets will alwa ys use diff erent
hop sequences.
