Systems and methods to adjust transmission power in electronic devices

An electronic device comprising:

• a first antenna;
• a second antenna;
• a processor in data communication with the first antenna and second antenna;
• and
• a hardware storage device in data communication with the processor, the hardware storage device having instructions stored thereon that, when executed by the processor, cause the processor to:
• access data containing material properties relating to a plurality of materials,
• transmit a first test signal on a first transmission channel with a first antenna at a first location in the electronic device,
• receive the first test signal on the first transmission channel with a second antenna at a second location in the electronic device,
• determine a housing material of the electronic device based on a measured attenuation of the first test signal received by the second antenna based upon the data containing material properties relating to the plurality of materials, and
• adjust a transmission power of one of the first antenna and second antenna based upon the material properties of the housing material.

A method for controlling wireless communication performance in an electronic device, the method including:

• accessing data containing transmission properties relating to a plurality of materials;
• transmitting a first test signal on a first transmission channel with a first antenna at a first location in the electronic device;
• receiving the first test signal on the first transmission channel with a second antenna at a second location in the electronic device;
• transmitting a second test signal on the first transmission channel with the second antenna at the first location in the electronic device;
• receiving the second test signal on the first transmission channel with the first antenna at the second location in the electronic device;
• determining a housing material of the electronic device based on a measured attenuation of the first test signal received by the second antenna, the second test signal received by the first antenna, and the data containing transmission properties relating to a plurality of materials;
• and
• adjusting a transmission power of a primary antenna based upon the transmission properties of the housing material.
