6.4.3. The Bluetooth protocol
The most convenient mode for monitoring
Bluetooth signals is a density graph,
since the Bluetooth protocol utilizes
frequency hopping transmissions. The
Bluetooth transmitter is turned off at
the first screenshot. An access point
is active at the 1st Wi-Fi channel. In
addition, signals with lower levels are
visible at other frequencies.
The PC is now searching for Bluetooth
devices. Transmissions are clearly
visible at a wide (from about 2430 to
about 2480 MHz) range.
Data is transferred from a PC to the
peripheral device. Apparently, Bluetooth
transmitter frequencies do not overlap
with active Wi-Fi channels (adaptive
frequency hopping algorithm is in use).
