The Ubiquiti UAP-AC-SHD is an indoor access point of the Unifi product family, specifically designed for high-performance and high-density environments. It supports the WLAN standard generation 802.11ac Wave 2 and offers a combined data rate of AC2550, with the 2.4-GHz band reaching up to 867 Mbit/s and the 5-GHz band up to 1667 Mbit/s. The access point is designed for use in professional networks where high user densities, stable connections, and comprehensive security features are required.

Applications

The UAP-AC-SHD is suitable for indoor spaces with high usage intensity, such as offices, conference rooms, educational institutions, or retail stores. It is particularly suitable when multiple clients simultaneously require high data rates without degrading network performance. The integrated MU-MIMO technology (Multi-User, Multiple Input, Multiple Output) enables parallel communication with multiple end devices, increasing overall network throughput. Support for Beamforming optimizes signal transmission by focusing the radio beam specifically on connected clients, improving range and signal quality.

Functions and Equipment in Detail

A central feature of the UAP-AC-SHD is the dedicated dual-band radio, which continuously monitors the environment and detects potential threats. This radio operates independently of the main processing unit and ensures continuous security monitoring. The airTime™ function provides real-time analysis of channel utilization at the packet level, enabling identification of bottlenecks and interferences without affecting network performance. airView® enables real-time analysis of the entire RF spectrum across all available channels to detect interference sources and channel occupancy.

Technology Explained Simply

The access point features CPU hardware acceleration, which handles QoS (Quality of Service), guest control, and client management directly at the hardware level. This reduces the load on the central processor unit and ensures lower latency. Additionally, a dedicated hardware offload for the 2.4-GHz and 5-GHz frequency bands is integrated, increasing maximum throughput with multiple simultaneous users. The Hardware-WIPS (Wireless Intrusion Prevention System) function provides a dedicated security processor for detecting and defending against unauthorized access and attacks on the WLAN.

Compatibility and Accessories

The UAP-AC-SHD is part of the UniFi ecosystem and is managed via the UniFi Controller, which represents a Software-Defined Networking (SDN) solution. It can be seamlessly integrated with other UniFi products such as switches and gateways. Available accessories include PoE injectors and surge protection devices, ensuring safe power supply over the network cable (PoE). Compatible switch models include, for example, the Ubiquiti EdgeSwitch 48 with 500W PoE+ and the EdgeSwitch 24 with 250W PoE+.

Mounting and Installation

The access point is connected via a network cable to a PoE-capable switch or a PoE injector. Installation takes place at a suitable wall or ceiling position, ensuring sufficient line-of-sight to clients. Configuration is performed via the UniFi Controller, accessible through a web interface or a mobile app.

Advantages in Operation

The UAP-AC-SHD offers high network performance combined with security and monitoring capabilities. Real-time analyses via airTime and airView enable proactive network maintenance. Hardware-based acceleration ensures low latency and high efficiency, even with many simultaneous users. Integration into the UniFi ecosystem enables centralized management and network scalability.
