Wireless Considerations Flashcards
Radio Frequency waves extend outward in all directions away from the antenna and the wireless access point at an equal power level
Vertical Antenna
Produces radio frequency waves extending outward in two directions
Dipole Antenna
A unidirectional antenna that sends the radio frequency waves in only one direction
Yagi Antenna
Allows the radio waves to be transmitted in only one direction over a longer distance than a Yagi Antenna
Parabolic Grid Antenna
The orientation of the electric field (or transmission) from the antenna
Polarization
A statistic or measure of the amount of airtime utilization that occurs for a particular frequency or channel
Channel Utilization
Radiates power equally in all directions
Omnidirectional
Focuses power in one direction for covering great distances
Unidirectional
