WAP stands for “Wireless Access Point”, which enables the wireless connection of end devices to a local network. In larger companies, these devices are part of a controller-controlled infrastructure, whereas in private environments they are integrated with a router and modem.
In a WLAN, access points form a station that is responsible for receiving and sending data. They also act as a connection point between the wireless network and the wired network (LAN). Access points use the IEEE 802.11 standard for short distances, whereas polling protocols with Time Division Multiple Access (TDMA) are used for longer distances. Each access point is capable of serving several users within a network area. When users leave the reception area of an access point, there is a seamless handover to the next access point. In smaller WLAN environments, a single WAP may be sufficient. However, the number of access points required depends on the number of users and the spatial extent of the network.
WAPs play an important role in providing wireless connectivity in modern network infrastructures. They also enable users to access information and resources in a mobile and flexible way. They can be used individually or in groups to ensure sufficient wireless network coverage.
