WiFi access points (APs) are networking devices that extend a wired local area network by providing wireless connectivity to client devices. An AP connects to a wired Ethernet network and broadcasts wireless signals to laptops, phones, printers, and other devices, creating a wireless LAN that clients join with an SSID. APs are distinct from basic home gateways or routers; while consumer devices may combine routing, switching, and wireless access in a single unit, standalone APs are designed for larger networks and are often managed centrally.

Deployment and management models vary. In small setups, a single AP can cover a space, while larger sites use multiple APs connected to a centralized controller or cloud-based management system. Some APs support Power over Ethernet (PoE) to simplify installation by delivering both data and power over a single Ethernet cable. APs typically support multiple SSIDs and VLAN tagging to separate guest networks from corporate traffic and apply different policies.

Standards and technology common to APs include IEEE 802.11 specifications such as 802.11a/b/g/n/ac/ax, with dual-band (2.4 GHz and 5 GHz) or tri-band configurations. Modern APs often use multiple-input, multiple-output (MIMO) and, in newer standards, technologies like OFDMA and beamforming to improve throughput and reliability.

Security features are a core aspect, with encryption standards such as WPA2 and WPA3. Enterprise deployments commonly use 802.1X authentication with a RADIUS server, while guest networks provide isolated access.

Use cases span homes, offices, campuses, and public hotspots. Practical considerations for deployment include optimal placement, interference management, backhaul capacity, and channel planning to maximize coverage and performance.
