Submission
Coexistence Liaison Report #1• 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
– NOT doing Physical Layer, implementation specific models
– NOT doing MAC layer simulations
