Question

Quizplus · Accepted Answer

John should use 1 dipole and 3 patch antennas to install a wireless LAN that will connect four buildings that are 100 meters apart.
Key Takeaway: Although John can use 4 Omni-directional antennas, such as dipoles, in this short-range scenario, for security reasons, he should use a single Omni-directional antenna and three semi-directional antennas. This uses only as much power as necessary at each antenna. This configuration forms a star topology, which is commonly used in point-to-multipoint connections.
