Patent ID: 8588220

Claim:
A method of mitigating port swapping during signal tracking, the method comprising: assigning a received wireless signal to a first port of a computing element; repeatedly acquiring signal characteristics of the signal and storing the acquired signal characteristics in a memory component; comparing a first one of the signal characteristics stored in the memory component to a second one of the signal characteristics stored in the memory component, the second one of the signal characteristics being acquired earlier in time than the first one of the signal characteristics; if the first and second signal characteristics vary, assigning the signal to a second port; and comparing a third one of the signal characteristics stored in the memory component to the first one of the signal characteristics stored in the memory component, the third one of the signal characteristics being acquired at a different time than the first one and the second one of the signal characteristics, and if the third and first signal characteristics vary, assigning the signal to the second port, wherein the signal is not present on the first port unless the signal has been assigned to the first port, the signal is not present on the second port unless the signal has been assigned to the second port, wherein the first signal characteristic is selected from the group consisting of a geolocation, an angle of arrival, a direction of arrival, a time difference of arrival, a frequency difference of arrival, and combinations thereof.
