Langaton tukiasema Teltonika DAP142 2,4 GHz Wi‑Fi 802.11n

The Teltonika DAP142 is a compact industrial wireless access point operating on the 2.4 GHz band and compliant with Wi‑Fi 4 (802.11n). Designed for industrial and small‑office deployments, it provides a maximum data transfer rate of 300 Mbit/s and supports up to 50 simultaneous client connections. The unit includes two RJ45 Ethernet ports, an RS232 port and supports passive Power over Ethernet (PoE) as well as an external 3‑pin power connector. Its aluminium housing with an integrated DIN‑rail bracket and plug‑and‑play setup make it suitable for installations that require robust mounting and reliable wireless coverage.

Advantages

The DAP142 delivers stable 2.4 GHz Wi‑Fi with Wi‑Fi mesh and Fast Roaming support to maintain connectivity across a covered area. Built for industrial environments, it offers a durable aluminium case, integrated DIN‑rail mounting and multiple interfaces including two Ethernet ports and RS232 for legacy or specialised equipment. Passive PoE and a separate 3‑pin power input provide flexible powering options, while support for modern security algorithms up to WPA3 ensures stronger wireless protection.

Suitable for

• Industrial automation and control rooms requiring DIN‑rail mounting
• Small offices and branch locations needing reliable 2.4 GHz coverage
• Environments with legacy devices that use RS232 connections
• Deployments that benefit from PoE or external power feed options
• Mesh networks and fast roaming scenarios across production floors or multi‑room sites

How to use

Mount the DAP142 on a DIN rail or place it in a suitable enclosure, then connect the network using an Ethernet cable to one of the RJ45 ports. Power the device via a PoE injector/switch supporting passive PoE or use the external 3‑pin power connector when PoE is not available. Configure wireless parameters, security settings and mesh or roaming features through the device web interface or the provided configuration tools. Connect RS232 peripherals where needed and verify client connectivity and signal coverage across the deployment area.

Recommendations

Place the access point centrally within the target coverage area and avoid metal obstructions to maximise 2.4 GHz range. Use passive PoE for simplified cabling when available; otherwise use the external power input. Enable WPA3 or the highest available security mode for client connections and plan mesh node placement to ensure seamless roaming across large or segmented spaces.
