Frequency hopping spread spectrum is used to share the medium among devices

in a Bluetooth piconet. Using an example, explain how this works.

Bluetooth allows frequency hopping with $79$ subcarriers. If two Bluetooth

piconets are operating simultaneously, what is the probability that they will

collide in any given frame?

In a WiFi network, what services are provided by each of Basic Service Set

$($BSS$)$ and Extended Service Set $($ESS$)?$

Briefly describe medium access sharing in WiFi, making specific reference to

inter$-$frame spacing.
