Power over Ethernet (PoE) is a term used to describe a set of standards that allows DC electrical power and data to be transmitted simultaneously along the same cable. This standard was first standardized in 2003 with IEEE802.3af and has been updated 2 more times since with the most recent, IEEE802.3bt, being ratified in September 2018. For the purposes of this post, the focus will discuss PoE as it relates to Access Points (AP).
Several varying types of antennas exist for WiFi, each with a specific purpose for how and when they should be used. Different types of antennas can be found anywhere from small office settings to outdoor camping grounds. While there are many types of antennas, all of them have the same purpose: producing radio waves to send information through the air. The three main antenna types are omnidirectional, semi-directional, and highly directional.
