Abstract:
1. A method comprising: by a computing device, receiving a signal through a first antenna that has a first resonant frequency, wherein the signal corresponds to a wireless communication to the computing device from another device, wherein the signal has a peak amplitude at one or more frequencies; by the computing device, accessing data encoding a frequency response shift corresponding to interference in the received signal, the frequency response shift being detected and encoded by a modem of the computing device coupled to the first antenna; by the computing device, determining an environmental or operational state of the computing device based at least in part on the frequency response shift encoded in the data; and by the computing device, in response to the determination of the state of the computing device, swapping a function from the first antenna to a second antenna based at least in part on the frequency response shift, wherein the second antenna has a second resonant frequency, and wherein a difference between the second resonant frequency and at least one of the one or more frequencies is less than a difference between the first resonant frequency and any of the one or more frequencies.
