2. Equally average use of frequencies
According to Bluetooth specifications the channel hopping sequence which has
a very long period length (23h 30’) does not show repetitive patterns over a
short time interval, but distributes the hop frequencies equally over the 79
hopping channels during a short time interval.
The histogram of the hopping sequence showed in the chapter 1 is the following
one:
For a hopping sequence of 98272 hops (approx. 1 min.) the histogram is:
