2. Directional antenna - Wikipedia

   en.wikipedia.org/wiki/Directional_antenna

   Patch antenna gain pattern. A directional antenna or beam antenna is an antenna which radiates or receives greater radio wave power in specific directions. Directional antennas can radiate radio waves in beams, when greater concentration of radiation in a certain direction is desired, or in receiving antennas receive radio waves from one specific direction only.

3. Antenna types - Wikipedia

   The nulls in the radiation pattern of small receiving loops and ferrite core antennas are bi-directional, and are much sharper than the directions of maximum power of either loop or of linear antennas, and even most beam antennas; the null directionality of small loops is comparable to the maximal directionality of large dish antennas (aperture ...

   The station has four radio interfaces each connected to a separate sector antenna, each providing 90 degrees coverage. Within 20 km of this base station, customer-premises equipment with high gain directional antennas are installed on sites which can then connect to the base station to receive broadband data connections of typically 10–200 ...

5. Hidden node problem - Wikipedia

   en.wikipedia.org/wiki/Hidden_node_problem

   Since nodes using directional antennas are nearly invisible to nodes that are not positioned in the direction the antenna is aimed at, directional antennas should be used only for very small networks (e.g., dedicated point-to-point connections). Use omnidirectional antennas for widespread networks consisting of more than two nodes.

   A 1 Gbit/s point-to-point millimeter-wave link installed in the UAE A point-to-point wireless unit with a built-in antenna at Huntington Beach, California. With the exception of passive optical networks, modern Ethernet is exclusively point-to-point on the physical layer – any cable only connects two devices.
