The Aruba 503 Series Access Points (APs) provide costeffective, high-performance connectivity for any organization experiencing device growth due to increased mobility, the shift to cloud, or IoT. With a maximum real-world aggregate data rate of 1.49 Gbps (HE80/HE20), the 503 Series deliver the speed and reliability needed for medium-density venues and workplaces such as schools, midsize offices, and retailers. Each 503 Series AP provides connectivity for a maximum of 256 associated clients per radio (512 in total).

OPTIMIZED USER EXPERIENCE

The 503 Series APs are designed to optimize user experience by maximizing Wi-Fi efficiency and dramatically reducing airtime contention between clients.

Features include orthogonal frequency-division multiple access (OFDMA) and cellular optimization. With up to 2 spatial streams (2SS) and 80MHz channel bandwidth (HE80), the 503 Series provides the next generation of wireless capabilities for cost-conscious deployments.

Advantages of OFDMA

This capability allows Aruba's APs to handle multiple Wi-Fi 6 capable clients on each channel simultaneously, regardless of device or traffic type. Channel utilization is optimized by handling each transaction via smaller sub-carriers or resource units (RUs), which means that multiple clients are sharing a channel and not competing for airtime and bandwidth.

Aruba Air Slice™ for application assurance

Aruba Air Slice delivers application assurance in order to optimize the user experience. By allocating radio resources such as time, frequency, and spatial stream to specific traffic types, Aruba APs can provide SLA-grade performance to client devices whether they support Wi-Fi 6 or prior standards.

Aruba Air Slice relies on Aruba's Policy Enforcement Firewall and Deep Packet Inspection (DPI) to identify user roles and applications so that bandwidth can be dynamically allocated to ensure performance. Air Slice is available for APs running controller-less mode (Instant) and with Aruba Central; controller-based APs will be supported in a future software release.

Wi-Fi 6 aware client optimization

Aruba's patented AI-powered ClientMatch technology eliminates sticky client issues by placing Wi-Fi 6 capable devices on the best available AP. Session metrics are used to steer mobile devices to the best AP based on available bandwidth, types of applications being used, and traffic type - even as users roam.

Resource management with AirMatch

To better support growth in client device density and in data volumes, AirMatch uses machine learning techniques that provide automated radio frequency optimization.
