This paper presents a brief overview of a patron queuing system in the communication sectors. Businesses have been faced with an ever-increasing demand from customers for convenient services. Customers do not want to spend their time waiting in a long queue. They want quick service because time is money & money is business. In order to meet this demand, service-based businesses need logistic data to help their operations run smoothly. The Patron Queuing System (PQS) counts the number of people waiting in the queue. It can then relay this number to the potential customer via website, PDA (Personal Digital Assistant). The PQS is installed in a location that ensures accurate data collection. More specifically, the sensor detects one person entering the queue at a time. The number of people entering and exiting the queue will be measured. The number of people in the queue will be relayed to the potential customer. There is a time delay when sending data from the PQS to the potential customer for viewing. The accuracy of the PQS is measured by comparing the data corresponding to the number of people in the queue at a certain time to the actual, real-time number of people in the queue. The time delay is not too long, as it would affect the accuracy and reliability of the PQS. The PQS has two user interfaces. One is for the potential customer, which is easy to read and accessible to all. The other is at the business and provides them with a way to know that the PQS is functioning properly. Internet connection from the business is necessary for the data to be sent from the PQS to the potential customer. The PQS operates in a wide range of temperatures and humidity. It is unobtrusive and unnoticeable to the patron and attempts to blend the PQS with the environment to reduce the risk of tampering. This review paper makes a brief survey of the queuing system concepts and the readers can make this as a base paper and do some extensive research in this exciting field.
