Claim 16:
17. A signal processing apparatus for controlling exposure to wireless communication, the signal processing apparatus comprising:
a look-up table including a plurality of combinations of reference reflection coefficients in association with a plurality of reference distances; and
processing circuitry configured to,
calculate a plurality of reflection coefficients of a plurality of first antenna modules,
obtain a plurality of distances based on the plurality of calculated reflection coefficients by referencing the look-up table, the plurality of obtained distances being distances to an external object from a plurality of second antenna modules, and
control transmission through the plurality of second antenna modules based on the plurality of obtained distances,
wherein
the plurality of first antenna modules are configured for wireless communication in a first frequency band,
the plurality of second antenna modules are configured for wireless communication in a second frequency band, and
the first frequency band is a lower frequency band than the second frequency band.
