Automatic Device Discovery (ADD)
To achieve higher data transmission, supporting directional communication needed in TG3c alternate PHY on 60GHz.
To reduce overhead of automatic device discovery (ADD), supporting omini antenna also needed for MAC design in PNC.
Proposed ADD has following features
Omni antenna for control CH (Low Rate PHY)
Device Discovery, Beaconing, etc
Directional antenna for transmission CH (High Rate PHY)
