The addition of wireless connections or “Wi-Fi” to networks has provided a cost-effective way to allow endpoints to communicate with both back-end resources and each other. Traditionally, copper cabling would need to be run throughout a building and an RJ45 ethernet port would need to be available at any location where there could potentially be a computer. On the backend, this causes a significant increase in networking equipment: patch panels to support each run and switch ports to support each network link. With wireless, an access point (AP) can be placed in an open location and provide connectivity to multiple endpoints while only utilizing a single port on a switch.
