Radio Frequency Radiation Exposure Mitigation Using Antenna Switching

摘要

Methods, devices, and systems embodiments enable a multi-antenna mobile device to mitigate radio frequency (RF) radiation exposure to users. A processor may determine a distance between the multi-antenna mobile device and the select portion of the user and switch from using a first antenna that is closer to the select portion of the user to using a second antenna when the multi-antenna mobile device is close to the user. The signal strength of the first antenna may be compared to the signal strength of a second antenna of the multi-antenna mobile device, and the second antenna may be used instead of the first antenna when the signal strength of the first antenna is within a predetermined threshold of the signal strength of the second antenna. If acceptable signal quality is not obtained with the second antenna, the multi-antenna mobile device may switch back to the first antenna.

1. A method of mitigating radio frequency (RF) exposure to a user of a multi-antenna mobile device having a first antenna and a second antenna, comprising:
determining whether the multi-antenna mobile device is within a predetermined distance from a select portion of the user; comparing a first signal strength of the first antenna to a second signal strength of the second antenna in response to determining that the multi-antenna mobile device is within the predetermined distance from the select portion of the user; and switching active communications from using the first antenna to using the second antenna in response to determining that the second signal strength of the second antenna equals or exceeds the first signal strength of the first antenna adjusted by a comparison threshold.
