Pagers, also called beepers, are channels of short-hand communication.One-way numeric pagers only receive messages consisting of a few digits, typically a phone number, that the user is then expected to call. Paging is a subscription service in Kahului offered in a variety of plans and options to meet the needs of a subscriber. Beepers were the first and the simplest form of paging ; they are called beepers because originally they made a beeping noise.
Modern paging systems use system delivery by satellite controlled networks in Kahului. This type of distributed system makes them inherently more reliable than terrestrial-based cellular networks for message delivery, as many paging transmitters may overlap a coverage area.
