Link emission control
First Claim
1. A second device for use in a communication link with a first device, the first device having a first shield portion, the second device comprising:
- a first EHF communication unit configured to receive a first electromagnetic EHF signal transmitted by the first device;
a second shield portion that provides partial shielding for the first EHF communication unit; and
a first signal controller coupled to the first EHF communication unit and configured to;
evaluate characteristics of the received first electromagnetic EHF signal to determine whether the first shield portion of the first device and the second shield portion of the second device are in alignment; and
in response to the evaluation indicating that the first shield portion and the second shield portion are in alignment, enable transmission of a modulated second electromagnetic EHF signal by the first EHF communication unit, the first electromagnetic EHF signal being unmodulated or having a lower level of modulation than the modulated second electromagnetic EHF signal.

Abstract
Establishing a communication link may include transmitting by a first device an unmodulated first electromagnetic EHF signal and receiving by a second device the first electromagnetic EHF signal. The second device may determine whether the received first electromagnetic EHF signal indicates that a first shield portion and a second shield portion are in alignment. The transmission of a modulated second electromagnetic EHF signal may be enabled when the received first electromagnetic EHF signal indicates that both the shield portions are in alignment and may be disabled when the received first electromagnetic EHF signal indicates that the first and second shield portions are not in alignment.
