These antennas have a bidirectional receiving pattern, with two peak directions 180 apart from one another and two null directions 180 apart from one another.
Each link defines a full-duplex (continuous bidirectional transmission and reception) point-to-point connection between two communicating pieces of electronics.
In fact, orientation for incoming students is a mandatory week-long writing and thinking workshop, designed to readjust students to pedagogical, cooperative bidirectional learning.
