1. An electronic messaging device, comprising:
- a receiver configured to receive a message at an operational frequency;
a controller operatively connected to the receiver;
a memory operatively connected to the controller and configured to store a message received by the receiver, a value of a first variable, and a value of a second variable; and
a power source configured to supply electrical power to the controller andwherein the controller is configured to;
operate the receiver at a first operational frequency;
determine a first filtered average received signal strength indication (RSSI) level of the first operational frequency based on a first plurality of measured RSSI levels, wherein only measured RSSI levels that are within a target RSSI range are included in the first plurality of measured RSSI levels;
when the determined first filtered average RSSI level of the first operational frequency is above a first threshold RSSI level;
increment the value of the first variable; and
when the value of the first variable is at a first threshold value, reduce the value of the second variable;
when the determined first filtered average RSSI level of the first operational frequency is below the first threshold RSSI level;
increment the value of the second variable; and
when the value of the second variable is at a secondthreshold value, operate the receiver at a second operational frequency.

Abstract
An electronic messaging device includes a receiver configured to receive a message at one of a first operational frequency and second operational frequency. The messaging device can operate using a time synchronous protocol and can receive commands through over-the-internet-programming (OTIP) and over-the-air-programming (OTAP).

18. A method, comprising:
-
electronically coupling a messaging device to a computing device, the messaging device locally storing a plurality of messages in a memory of the messaging device; uploading the plurality of messages from the memory of the messaging device to the computing device through the coupling; subsequent to the messaging device being added to a message distribution group comprising a plurality of existing messaging devices, receiving from the computing device a test communication through the coupling to test an operation of the messaging device and confirming the addition of the messaging device to the message distribution group without communicating with the existing messaging devices; and when the test communication is successfully received, indicating receipt of the test communication. - View Dependent Claims (19, 20, 21, 22)

23. A messaging device, comprising:
-
a data communication interface; a rechargeable power source; a charging system operatively coupled to the data communication interface and the rechargeable power source; a processor operatively coupled to the rechargeable power source; and a non-transitory computer readable medium having instructions stored thereon, which when executed by the processor cause the processor to; receive messages on one of a first local operational frequency and a wide-area operational frequency, wherein the local operational frequency is associated with a private network and the wide-area operational frequency is associated with a public carrier network using a synchronous paging protocol; receive programming commands through the data communication interface; receive an electrical charge through the data communication interface; subsequent to the messaging device being added to a message distribution group comprising a plurality of existing messaging devices, receive from a computing device a test communication through the data communication interface to test an operation of the messaging device and confirm the addition of the messaging device to the message distribution group without communicating with the existing messaging devices; and when the test communication is successfully received, indicate receipt of the test communication. - View Dependent Claims (24, 25, 26)
