Final answer:
The assignment of calls to specific time intervals on a selected frequency in cellular networks is achieved using Time Division Multiplexing (TDM), a key component in communications technology that ensures efficient management of call traffic.
Step-by-step explanation:
The concept being described here relates to the field of communications technology, specifically how cellular networks manage the assignment of frequencies for phone calls. In cellular networks, a technique known as Time Division Multiplexing (TDM) is often used, which assigns each call a particular slot of time on a chosen frequency. This allows multiple calls to share the same frequency channel by slicing time into discrete intervals and assigning each call a specific time interval or slot.
In the given examples, we see various applications of probability concepts to determine the frequency and timing of events, such as phone calls at a call center or on an individual's phone. For instance, the cumulative distribution function P(T < t) = 1 − et can be used to calculate the probability of a call occurring within a certain time frame, based on the average rate at which calls are received.
Consequently, the system that assigns calls to specific time intervals on a frequency is crucial for smoothly managing the traffic in cellular networks and ensuring that each user is able to communicate without interference from other calls.
