We have $24$ wireless transmitters that send $40$ bit packets at y bits per second and ONE packet per minute.

Each transmitter chooses a time$-$slot in a minute to send their bits.

The number of time$-$slots in a minute can be decided using $($y$/40)*60$

e$.$g: y $=40$bps$,$ number of time$-$slots $=(40/40)*60=60$ time$-$slots

When we have two or more transmitter, there will be collision causing a backlog.

The number of wireless terminals is proportional to the probability of a packet. The probability cannot be zero.

Come up with a reliable design for a wireless multiple access system to collect all $24$ packets WITHIN one minute.
