Abstract
A method of reducing interference in a GPS-equipped wireless device having a transmitter, the method comprising: acquiring a GPS signal containing GPS data; decoding the GPS data; determining whether the GPS data is valid; when the GPS data is not valid due to the interference, determining a transmit power level of the transmitter; and when the transmit power is not zero, reducing the transmit power level by one step.
Claims16
A method of reducing interference in a GPS-equipped wireless device having a transmitter, the method comprising:
- acquiring a GPS signal containing GPS data;
- decoding the GPS data;
- determining whether the GPS data is valid;
- when the GPS data is not valid due to the interference, determining a transmit power level of the transmitter;
- and
- when the transmit power level is not zero, reducing the transmit power level by one step.
An apparatus for reducing interference in a wireless device, the apparatus comprising:
- a GPS receiver for acquiring a GPS signal containing GPS data, decoding the GPS data, and determining whether the GPS data is valid;
- means for determining transmit power of the transmitter when the GPS data is not valid due to the interference;
- and
- means for reducing the transmit power level by one step when the transmit power is not zero.
A method of reducing interference in a GPS-equipped wireless device having a transmitter, the method comprising:
- acquiring a GPS signal containing GPS data;
- decoding the GPS data;
- determining whether the GPS data is valid;
- determining a transmit power level of the transmitter when the GPS data is not valid due to interference caused by E911 service;
- reducing the transmit power level by at least one step when the transmit power level is not zero;
- and
- reporting that there is no GPS signal and setting the mobile transmitter to normal operation when the transmit power level is zero.
