Controlling electromagnetic radiation from an electronic device

1. A method of controlling electromagnetic radiation from an electronic device, comprising:

detecting, by the electronic device, presence of an accessory that is attachable to the electronic device, where a portion of the accessory when attached to the electronic device provides an electromagnetic radiation shield; and

in response to detecting presence of the accessory, changing, by the electronic device, a transmission power of a wireless communications module of the electronic device.

2. The method of claim 1 , wherein changing the transmission power comprises increasing a transmission power ceiling of the wireless communications module.

3. The method of claim 2 , further comprising:

in response to detecting absence of the accessory, reducing the transmission power ceiling of the wireless communications module.

4. The method of claim 1 , wherein detecting presence of the accessory comprises detecting presence of a protective case having a cover moveable between an open position and a closed position.

5. The method of claim 1 , wherein detecting presence of the accessory comprises detecting presence of a sleeve into which the electronic device is insertable.

6. The method of claim 1 , wherein detecting presence of the accessory comprises detecting presence of the accessory that provides a functionality in addition to functions of the electronic device.

7. The method of claim 1 , wherein detecting the presence of the accessory comprises detecting based on proximity of the electronic device to a magnet of the accessory.

8. The method of claim 1 , wherein detecting the presence of the accessory comprises detecting based on electrical connection to an electronic circuit of the accessory.

9. The method of claim 1 , wherein detecting the presence of the accessory comprises detecting based on mechanical interaction between the electronic device and the accessory.

10. The method of claim 1 , wherein detecting the presence of the accessory comprises detecting using an optical sensor to detect proximity of the accessory.

11. An electronic device comprising:

a wireless communications module to perform wireless communications; and

a control mechanism for controlling electromagnetic radiation from the electronic device, the control mechanism to:

detect an object of an accessory that has a portion for providing an electromagnetic radiation shield;

increase a transmission power ceiling of the wireless communications module in response to detecting the object; and

reduce the transmission power ceiling of the wireless communications module in response to not detecting the object.

12. The electronic device of claim 11 , wherein the control mechanism is to detect the object using at least one selected from the group consisting of: detect the object that includes a magnet, detect electrical connection in an electronic circuit of the object, detect mechanical interaction with the object, and detect by use of an optical sensor.

13. The electronic device of claim 11 , wherein the control mechanism is to detect the object that is part of the accessory selected from the group consisting of a protective case and a sleeve.

14. An accessory for attachment to an electronic device, comprising:

a base to support the electronic device, wherein the base provides an electromagnetic radiation shield; and

a detectable object in the base, the detectable object being detectable by a detector of the electronic device to cause adjustment of a transmission power of a wireless communications module of the electronic device based on detection of presence of the detectable object by the detector, for controlling electromagnetic radiation from the electronic device.

15. The accessory of claim 14 , comprising one of a protective case and a sleeve.
