Join Mike Chapple for an in-depth discussion in this video Wireless signal propagation, part of CompTIA Security+ (SY0-501) Cert Prep: 2 Technologies and Tools.
- [Instructor] The radio waves that carry…wireless network traffic are affected…by many different characteristics…as they travel across an area.…Building materials, antenna placement,…wireless power levels, and many other characteristics…can alter the flow, or propagation, of wireless signals.…First, there are many different types…of wireless antennas that may be used.…While many organizations use the simple antennas…built in to wireless access points,…there are other options available.…
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 donut-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…
