Have a question regarding probability. We have a device that communicates wirelessly to a main router and no devices can transmit with in the same time period as any other device. Can anyone provide an equation that would solve what the probability is of any device transmitting at the same time slot when there is X number of devices trying to communicate? Details: Devices take 5 msec to transmit all data Devices will transmit new data every 5000 msec Data with be corrupt if two or more devices transmit during any part of each others active transmission. For example first device transmits at time 0 msec and device two transmits at time 4.5msec there will be a collision of data at the last 500 msec and cause a fault. What the probability when you have X number of devices running? * This is a actual problem we are trying to solve at our office, not a homework question, have a few answers but each solution is different by a decent amount.
