The radio waves that carry wireless network traffic are affected by many different characteristics as they travel across an area. Building materials, antenna placement, power levels, and many other characteristics can alter the flow, or propagation, of wireless signals. In this video, learn how different conditions affect wireless signal propagation, including antenna types and beamforming, site surveys and antenna placement, and power level controls.

There are two basic categories of antenna.…The basic antennas used with wireless access points…are known as omnidirectional antennas.…They transmit radio waves in a doughnut-shaped pattern.…The short, stubby, pole-like antennas…attached to wireless access points…are known as rubber ducks…and are examples of omnidirectional antennas,…antennas that send that wireless signal…in almost every direction.…In some cases, network administrators may wish…to point a wireless signal in a specific direction,…such as when they're creating a point-to-point network…
