Wireless access points are networking devices that allow Wi-Fi devices to connect to a wired network. An access point connects to a wired router, switch, or hub via an Ethernet cable, and projects a Wi-Fi signal to a designated area. For example, if you want to enable Wi-Fi access in your company’s production area but don’t have a router within range, you can install an access point near the front desk and run an Ethernet cable through the ceiling back to the server room.
Some wireless access points are integrated into a wireless router, but standalone ones are usually connected to a router via a wired Ethernet connection to provide access to the network using radio frequency links to enable other devices to access the wired connection.
Wireless access points are capable of communicating with up to 30 different clients over a distance of around 103 meters. However, these are maximums, and usually, there will be limitations to these imposed by the placement of the wireless access point, the structure and design of the building or area in which it is located and the presence of other devices which may interfere with its signal.
Other factors which can affect the efficacy of a signal of Wireless access points include the weather, the type of antenna used and the power output of the devices used. The range of an access point can be extended using repeaters to increase the radio signal or reflectors which allow the signal to be bounced around within the target area.
