Extremely high frequency systems and methods of operating the same

A first apparatus including:

• an extremely high frequency (EHF) transceiver;
• and
• control circuitry coupled to the EHF transceiver, the control circuitry operative to:
• control establishment of an EHF communications link with a second apparatus by executing a state machine that tracks a state of the first apparatus by transitioning through a plurality of states in response to satisfaction of any one of a plurality of conditions;
• establish the EHF communication link with the second apparatus to selectively enable one of transmission and reception of data;
• after the EHF communication link with the second apparatus is established, monitor an absence of data being communicated over the EHF communication link;
• and
• enter into a power savings state in response to the monitored absence of data being communicated over the EHF communication link until the state machine transitions to a new state.
