Claim 14:
15. The method of claim 12 comprising:
the determining the characteristic signal relates to determining a time of flight characteristic;
determining a first time of flight characteristic based on a first plurality of time-spaced measurements of the at least one antenna output, wherein the first plurality of time-spaced measurements are based on wireless communications received according to a first communication protocol via at least one first communication protocol channel;
determining a second time of flight characteristic based on a second plurality of time-spaced measurements of the at least one antenna output, wherein the second plurality of time-spaced measurements are conducted with respect to wireless communications that occur on different frequencies, wherein the second plurality of time-spaced measurements are based on wireless communications received according to a second communication protocol via at least one second communication protocol channel;
wherein the second communication protocol is different from the first communication protocol such that an encoding of communications received according to the second communication protocol is different from an encoding of communications received according to the first communication protocol.
