How to calculate the probability of choosing a dynamic Wi-Fi frequency

Question

I have no idea how I can handle this issue.

Let them say that 802.11h AP points are spreading all over the street.

#52, #56 ...., #140 

A bus connected to channel No. 52 moves along this street at a constant speed.

What is the likelihood that this bus will change its AP?

Thanks.

Answer 1

It almost sounds like a trick. The way to write the answer is definitely 100% .
That is, if the constant bus speed is 0 or the AP range is ∞.
