The frames generated by active users of a wireless channel follow

Poisson$$s distribution. If T represents the frame time and G represents the

mean number of transmissions per frame time, what is the

i$.$ Probability of k transmission attempts per frame time?

ii$.$ When is the probability that $0$ frames are generated in the collision

duration in pure ALOHA?

iii. What is the throughput of the pure ALOHA?

iv$.$ Determine the throughput if the channel is accessed using slotted

ALOHA.
