Bandwidth
A Bluetooth radio link has a maximum data
transfer rate of 724 kbit/s, or three voice
channels; the data rate for a voice channel is 64
kbit/s.
Security
Two advanced security mechanisms ensure a
high level of security:
§ Authentication prevents access to critical
data and makes it impossible to falsify the
origin of a message.
§ Encryption prevents eavesdropping and
maintains link privacy.
Low power consumption
The Bluetooth radio is very economical, limiting
its output power exactly to what is actually
needed. For instance, when transmitting to a
receiving radio that is only a couple of meters
away, the radio immediately modifies its signal
strength to suit the small distance. Bluetooth
consumes only a tiny bit of the power that eg. a
mobile phone needs.
