In “Ad-hoc Communication” mode,communication is also possible with Bluetooth® SPP devices from othermanufacturers.AFH(Adaptive Frequency Hopping)The adaptive frequency hopping process is used to temporarily skip faulted oroccupied sections of the total available frequency band and use other channels.Allowed deviceDevice with which a connection can be established. Devices not included in thiscategory cannot connect.ApplicationAn application is a computer program developed by the user.ASCII(American Standard Code for Information Interchange)The basis for character set coding. Character encoding defines 128 characters,consisting of 33 non-printable and 95 printable characters. Each character isassigned a bit pattern consisting of 7 bits. Since each bit can have two values, atotal of 27 (= 128) different bit patterns exist, which can be interpreted as wholenumbers 0–127 (hexadecimal 00–7F).AuthenticationAuthentication is a process for testing the identity transmitted by a communi-cation partner.Available deviceDevice, that is physically in range and ready to connect and ready for use.BBasebandA baseband is referred to if the desired signal is transmitted in an unalteredfrequency range. In wireless communication systems, wireless transmission doesnot usually take place in the baseband, but rather by modulation of a significantlyhigher frequency carrier signal with the baseband signal.
