An access point acts as an interface for wireless communication devices, enables data exchange and receives signals via an Ethernet cable connection to the router. This creates a separate WLAN network that enables convenient surfing in remote living areas and supplies additional end devices with fast WLAN. Wireless access points connect mobile devices to a LAN or other wired data network via Wi-Fi and are particularly useful for demanding applications such as home office, streaming and gaming.
Compared to repeaters, access points aim to extend the home network and amplify the Wi-Fi signal. The main difference is that access points receive router data via an Ethernet cable, which is more efficient for optimal Wi-Fi performance, while repeaters do this wirelessly, which is less efficient over long distances. Wireless access points perform similar functions to bridges and switches by connecting different devices at a hardware level, avoiding data collisions. In the OSI model, access points, like switches and bridges, are located in the data link layer. In contrast, the Ethernet protocol covers both the data link layer and the underlying bit transmission layer.
The advantages of an access point are the provision of strong WLAN for additional end devices, optional LAN connection options for data-intensive applications and full data utilization thanks to the Ethernet connection to the router, in contrast to WLAN expansion using repeaters.
