Radio-paging system enables us to be in touch even though we do not have a telephone within easy reach. It is a way of letting us know that something important has just happened and that we must act quickly. The system works through a pager of “beeper”, a small receiver about the size of a packet of cigarettes, which you can keep in your pocket. When people want to get in touch with you, they simply pick up the nearest telephone , dial your personal paging number, and wherever you are in the covered area, your pager will bleep. The bleeping informs you that someone is calling you.
Many companies which have personal on business trips have frond that radio-paging improves their competitive position and allows them to be more responsive to a lot of their customers' needs. It also makes a company's business easier by cutting out many unnecessary and expensive journeys that are sometimes made by salesman. This saves time and fuel costs. Doctors can be found immediately and returned to their surgery or hospital, thus possibly saving the life of a very sick patent.
