Link emission control
First Claim
1. A method for managing a communication link, comprising:
- transmitting by near field coupling from a first device, a first electromagnetic EHF signal that is low-level modulated with a predefined code required by a corresponding second device;
receiving by near field coupling to the first device a second electromagnetic EHF signal transmitted by the second device;
determining by the first device whether the received second electromagnetic EHF signal is modulated with a high level of modulation; and
in response to a determination that the received second electromagnetic EHF signal is modulated with a high level of modulation, transmitting the first electromagnetic EHF signal with a high level of modulation, the first electromagnetic EHF signal that is low-level modulated having a narrower frequency band of emissions than the first electromagnetic EHF signal with the high level of modulation.

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.

4. A first device for establishing a communication link with a second device, the first device comprising:
-
a first EHF communication unit configured to transmit to the second device a first electromagnetic EHF signal that is low-level modulated with a predefined code required by a corresponding second device; a second EHF communication unit configured to receive a second electromagnetic EHF signal transmitted by the second device; and a signal controller configured to determine whether the received second electromagnetic EHF signal is modulated with a high level of modulation; and
if the received second electromagnetic EHF signal is modulated with a high level of modulation, to disable transmission of the first electromagnetic EHF signal that is low-level modulated by the first communication unit, and to enable transmission of the first electromagnetic EHF signal with a high level of modulation, the first electromagnetic EHF signal that is low-level modulated having a narrower frequency band of emissions than the first electromagnetic EHF signal with the high level of modulation. - View Dependent Claims (5, 6, 8, 10)
