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. Learn how different conditions affect wireless signal propagation, including antenna types and beamforming, site surveys and antenna placement, and power level controls.
