The TAP400 Wi-Fi 6 Access Point in depth
Wi-Fi 6 performance for multi-user networks
The TAP400 supports 802.11b/g/n/ac/ax (Wi-Fi 6) on dual band with MU-MIMO, reaching data rates up to 2402 Mbps on 5GHz and 576 Mbps on 2.4GHz. A dedicated RJ45 port supports 100/1000/2500 Mbps for a 2.5 GbE uplink, and the access point handles up to 512 simultaneous connections. Three internal omnidirectional antennas cover both 2.4 GHz and 5 GHz bands.
Always-on coverage and seamless expansion
Wireless mesh (802.11s), fast roaming (802.11r), BSS transition management (802.11v) and radio resource measurement (802.11k) help maintain network continuity and extend coverage. Security options include WPA3-SAE, WPA3-EAP, OWE, 802.11w Protected Management Frames, MAC-based access control, and tag-based VLAN separation. A wireless QR code generator lets users join the network without entering login details.
Remote management with RMS and RutOS
Configuration, monitoring and troubleshooting can be handled remotely through Teltonika RMS, including firmware and configuration updates for multiple devices at once. The network map helps you visualise your setup. The TAP400 runs RutOS (OpenWrt based Linux OS) and supports FOTA updates, a Web UI, SSH, JSON-RPC and Data to Server using HTTP(S), MQTT and Azure MQTT.
Compact, ceiling-mounted design
The TAP400 measures Ø 158 mm x 31.4 mm and weighs 285 g, with a casing of UV stabilized plastic and aluminium. It mounts to the ceiling using an AP mounting bracket and operates from 0 °C to 50 °C at 10% to 90% non-condensing humidity, with an IP30 rating. Power consumption is under 7 W idle and under 11 W at maximum.
