Method and system for analyzing received signal strength
First Claim
1. In a communications system comprising a plurality of remote transmitting devices and a receiving station having a receiver associated therewith, a method for automatically testing the communications system comprising the steps of:
- a) receiving at said receiving station a received signal from a transmitting device;
b) generating RSSI data indicative of the signal strength of said received signal;
c) determining the ID of said transmitting device from said received signal;
d) retrieving from a first memory location associated with said ID stored signal information;
e) comparing said stored signal information with said RSSI data; and
f) when said comparison is unfavorable, then indicating a trouble condition.

Abstract
A self testing wireless data communications system suitable for use with an alarm system, the receiving element of the communications system is capable of measuring the signal strength (RSSI) of the received message and comparing it with stored signal information from a memory location associated with the ID of the transmitting device. Upon an unfavorable comparison, the system indicates a trouble condition by updating a user-interface visual display and/or alerting a central station. The system may have additional features such as the stored signal information may be updated to produce a running average of the RSSI of each message, or the indication of a trouble condition may include intelligent processing prior to updating a user-interface visual display. The system further comprises apparatus for initiating an install mode wherein a transmission from each of the remote devices causes RSSI data indicative of the signal strength of the received signal to be stored in the storage apparatus at a location associated with the ID of the remote device.
