Method and system for diagnosing radio performance during functional over-the-air operation
First Claim
1. An apparatus for determining a health of a mobile radio-frequency transmitter, the apparatus comprising:
- a receiver for receiving a received signal responsive to a transmitted signal transmitted from the mobile transmitter, the transmitted signal transmitted during normal over-the-air operation of the mobile transmitter and not having known signal characteristics;
a first element for determining a first signal parameters value of the received signal, the first signal parameter value responsive to signal power of the received signal;
the first element for determining additional signal parameter values of the received signal;
the transmitted signal and the received signal each including an identifier of the mobile transmitter, the identifier for linking the first signal parameter value and the additional signal parameter values with the mobile transmitter; and
a second element for determining whether the first signal parameter value exceeds a predetermined value;
if the first signal parameter value exceeds the predetermined value, the second element for determining a health of the mobile transmitter, the health responsive to a relationship between one or more of the additional signal parameter values and a respective specification value or a range of respective specification values for each one of the additional signal parameter values, wherein the respective specification value or the range of respective specification values are independent of distance and link quality between the mobile transmitter and the receiver.

Abstract
An apparatus for determining a health of radio-frequency transmitters each transmitting a transmitted signal during normal operation. The apparatus comprises a receiver for receiving received signals, each received signal responsive to a transmitted signal, a first element for determining signal parameters of each received signal, the signal parameters responsive to an operating condition of a transmitter, each transmitted signal and each associated received signal including an identifier of the transmitter that transmitted the transmitted signal, the apparatus using the identifier to link determined signal parameters with the transmitter that transmitted the transmitted signal and a second element for determining a health of the transmitter that transmitted the transmitted signal, the health responsive to a relationship between one or more signal parameters and a selected value or a range of selected values for each signal parameter.

19. A method for determining a health of a radio-frequency (RF) transmitting device, the method comprising:
-
at a receiver, receiving an RF signal transmitted from an RF transmitting device, the transmitted signal transmitted during normal over-the-air operation of the RF transmitting device and not having known signal characteristics; measuring a first signal parameter value related to signal power and measuring additional signal parameter values of a received RF signal, the received RF signal responsive to the transmitted signal; determining whether the first signal parameter value exceeds a threshold value for the first signal parameter value; determining a health of the RF transmitting device responsive to the additional signal parameter values only when the first signal parameter value exceeds the threshold value, wherein the health is responsive to a relationship between each one of the additional parameter values and a respective specification value for each one of the additional signal parameter values, wherein the specification values are independent of distance and link quality between the transmitting device and the receiver; and wherein the received RF signal includes an identifier of the RF transmitting device, using the identifier to link a health determination with the RF transmitting device.
