Coexistence Liaison Report 2
  • Bluetooth Coexistence Working Group
  • Chartered by Bluetooth SIG to address coexistence
    issues of Bluetooth with other devices operating
    in the 2.4 GHz ISM unlicensed band
  • Chaired by Tod Sizer of Lucent
  • Members include Lucent, Motorola, Ericsson,
    Toshiba, 3COM

Coexistence Liaison Report 2
  • Simulations
  • Matlab
  • Time Frequency simulations - assume a
    particular time usage (due to specific traffic
    models) together with frequency hoping scenarios
    to establish collision rate between Bluetooth and
    the interfering system

Coexistence Liaison Report 2
  • Recent Work
  • OpNet Tutorial from Taylor Salman
  • Internal papers covering Fading Model and Path
    Loss Model
  • Audio samples in WAV format output from two CVSD
    Corruption Simulators
  • Input requirements to Bluetooth Radio 2 Group

Coexistence Liaison Report 2
  • Audio samples in WAV format output from two CVSD
    Corruption Simulators
  • Lost packet filled with white background noise
    encoded in binary as alternating ones and zeros
    of the same size as the lost packet(s). Assumes
    packet headers have been corrupted during
    transmission, allowing the decoder to recognize a
    corrupt packet and handle it accordingly.
  • Assumes packet headers have been left intact,
    preventing the decoder from recognizing the
    packet as corrupt. 50 of the lost packets are
    recognized as corrupt and treated as above, while
    the other 50 are filled with random bits
    simulating the corrupted payload.

Coexistence Liaison Report 2
  • Face-to-Face Meeting
  • Expected in mid October
  • Plans to begin testing of real hardware
