Built on Wi-Fi 6 standards, 550 Series APs include features such as OFDMA, bidirectional MU-MIMO, and Target Wait Time for better multi-user performance and improved efficiency.
IoT and location-ready
HPE Aruba Networking’s Wi-Fi 6 AP provides support for Zigbee, Bluetooth 5, and third party overlays to simplify the deployment and management of IoT services and provide telemetry for contact-tracing dashboards in HPE Aruba Networking Central.
Simple and secure access
Protects network security with stronger encryption and authentication, secure credentials/keys storage, and user and IoT access policy enforcement firewalls.
Features
For large indoor, extremely high-density spaces, the 550 Series APs provide up to 5.37 Gbps maximum wireless speed with dual radios and optional tri-radio mode.
Wi-Fi 6 OFDMA and MU-MIMO, plus ClientMatch
Handles multiple clients on each channel, regardless of device or traffic types, and uses AI-powered RF to eliminate sticky client issues.
WPA3 and Enhanced Open security
Increases enterprise-level security without increasing complexity, and ensures stronger guest access protections.
Air Slice for SLA-grade performance
Provides service level agreement-grade performance for latency-sensitive, high-bandwidth, and IoT services.
