22. A device for wireless communication and wireless sensing, the device comprising:
a digital-to-analog converter (DAC) configured to:
convert a first digital wireless communication signal into a first analog wireless communication signal, wherein the DAC receives the first digital wireless communication signal from a first path; and
convert a first digital wireless sensing signal into a first analog wireless sensing signal, wherein the DAC receives the first digital wireless sensing signal from a second path different from the first path, the first path including a modem of the device, the modem generating the first digital wireless communication signal, the second path bypassing the modem; and
one or more transmitting antennas configured to:
transmit the first analog wireless communication signal and the first analog wireless sensing signal.
