Abstract

When a Nationwide pager user travels from one transmitting zone to another, the user is generally uncertain as to when the receiver is in range of the new transmitter on which information will be sent. By using a selective call receiver which receives and decodes transmitted channel identification information in a Nationwide communication system (such as that described in United States Patent 4,644,347 to Lucas et al), and which includes a location alarm, one can remove this uncertainty.
