ABSTRACT:
A paging receiver is disclosed which is compatible with transmissions from analog or digital paging transmitters. The paging receiver has a command structure which permits it to be dynamically programmable to change its functionality including programming of the channels which the paging receiver is to receive. The programmability of the channels permits the paging receiver to be used for making national, regional, remote area, local area, and sublocal area pages, and pages to a group in the local area and to switch from channels which are heavily used during peak paging times to lesser used channels. The paging receiver transmits the paging receiver identification code digits in an order of increasing significance which significantly lessens power consumption for all paging receivers tuned to a particular channel for determining if a page is to be received which prolongs paging receiver battery life. The paging receiver displays the place of origin of pages as either being of local origin or from other areas. The paging receiver antenna is continuously tunable to permit compensation for variation in antenna gain caused by environmental factors which can seriously degrade signal strength.
