Methods and devices for mitigating interference with FHSS signals
First Claim
1. A method of mitigating interference with a first signal that is a signal of a frequency hopping spread spectrum system, wherein the frequency hopping spread spectrum system utilizes a set of designated frequency channels, comprising:
- detecting, with a radio communications device, a second signal that is not a frequency hopping spread spectrum signal;
determining, with the radio communications device, a property of said second signal;
comparing the property of the second signal with at least one property of each of the set of designated frequency channels;
determining, with the radio communications device, at least one of the set of designated frequency channels used by said frequency hopping spread spectrum system as having the at least one property that is most similar to said property of said second signal; and
modifying usage, with the radio communications device, of said at least one most similar designated frequency channel by said first signal to communicate data so as to mitigate interference between said first and second signals by reducing a frequency bandwidth for the data of the first signal when said first and second signals are concurrently communicating on the at least one similar designated frequency channel during simultaneous transmission of said first and second signals.

Abstract
Methods and devices for mitigating interference with a signal of a frequency hopping spread spectrum system are disclosed. A second signal is detected, and a property of the second signal is determined. At least one of a set of designated frequency channels used by the frequency hopping spread spectrum system is determined as having a property most similar to that of the second signal. The usage, by the frequency hopping spread spectrum system, of the at least one most similar designated frequency channel is then modified, for communication of data.

9. A radio communication device, said device comprising:
-
a first unit configured to use a frequency hopping spread spectrum system to generate a first signal to communicate data; a scanner configured to detect second signal that is not a frequency hopping spread spectrum signal; and a processor configured to; determine a property of said second signal; compare the property of the second signal with at least one property of each of the designated set of frequency channels; and determine at east one of a set of designated frequency chancels used by said frequency hopping spread spectrum system as having a property most similar to said property of said second signal, wherein said unit is further configured to modify usage of said at least one most similar designated frequency channel by said first signal to communicate data by reducing a frequency bandwidth for the data of the first signal so as to mitigate interference between said frequency hopping spread spectrum signal and said second signal when said frequency hopping spread spectrum signal and said second signal are concurrently communicating on the at least one most similar designated frequency channel during simultaneous transmission of said frequency hopping spread spectrum and second signals. - View Dependent Claims (10, 11, 12, 13)

14. A monitoring apparatus comprising at least a monitoring device comprising:
-
at least one image capturing unit configured to capture image data; and a dual mode radio communications device comprising; a first unit configured to generate a first signal using a frequency hopping spread spectrum format to communicate data derived from said image data; a second unit configured to communicate with a device that generates a second signal that uses formats other than said frequency hopping spread spectrum format; and a processor configured to; detect and determine a property of said second signal; compare the property of the second signal with at least one property of each of the designated set of frequency channels; and determine at least one of a set of designated frequency channels used by the frequency hopping spread spectrum format as having a property most similar to that of said second signal, wherein said first unit is further configured to modify usage of the at least one most similar designated frequency channel by said first signal to communicate said data by reducing a frequency bandwidth for the data of the first signal so as to mitigate interference between said first and second signals when said first signal and second signal are concurrently communicating on the at least one most similar designated frequency channel during simultaneous transmission of said first and second signals. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
