BlueFRITZ! USB – 5 How BlueFRITZ! USB Works 45

5.3 The Bluetooth Technology of BlueFRITZ! USB

BlueFRITZ! USB is a Bluetooth device for the USB port, suited

especially for working with notebooks at changing locations.

BlueFRITZ! USB works at the highest Bluetooth performance

class for all connections. This means BlueFRITZ! USB attains

a range of up to 100 m for line-of-sight connections with

100 mW transmission power. The effective range of the de-

vice depends not only on transmission power, but also on

the location where the Bluetooth connections are estab-

lished.

BlueFRITZ! USB supports the connection of up to eight Blue-

tooth devices in a wireless network. Connecting to AVM ac-

cess points grants BlueFRITZ! USB wireless access to ADSL

and ISDN as well.

The Bluetooth client BlueFRITZ! USB is specifically designed

for communication, media access and data transmission.

5.4 Optimum Connections with Bluetooth

Profiles

Bluetooth allows multiple applications to operate on a con-

nection at the same time. It offers secured procedures for the

transmission of data, digitalized tones and speech, which

are implemented by what are known as profiles.

Bluetooth profiles are agreements between Bluetooth devic-

es, negotiated when a Bluetooth connection is established

between devices. This guarantees that all data are transmit-

ted in the form needed by the application. When devices

with the same capabilities, and thus the same profiles, are

connected to each other, the profiles determine all parame-

ters of the Bluetooth transmission. For the user this means

that it is no longer necessary to configure the details of

transmission.

BlueFRITZ! USB supports the profiles A2DP, CIP, DUN, FTP,

HCRP, Headset, OPP, PAN and SPP, and in this context also

supports the “Profile on Demand” function. Only the profiles

CIP and PAN are established automatically every time the

program is started. All other profiles are established and
