Overview:

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).

Greater efficiency

Built on Wi-Fi 6 standards and Wi-Fi CERTIFIED®, 503 Series APs include support for OFDMA for higher throughput and Target Wake Time to extend the battery life of IoT devices.

Simple and secure access

Aruba 503 Series Indoor Access Points offer enhanced security with WPA3 and Enhanced Open for stronger encryption and guest access. The Trusted Platform Module secures credentials, keys, and boot code while the Policy Enforcement Firewall automatically applies policies based on user role, device type, applications, and location and dynamically segments traffic.

Cost effective, comprehensive coverage

Options include single or eco-friendly ten-packs for affordable indoor Wi-Fi coverage for low-to-medium density environments. USB plug-ins for IoT or for LTE modem support are also available.

1.49 Gbps maximum real-world speed

Delivers speed and reliability with HE80/HE20 channels for K-12 schools, branch offices, and retail stores.

Dynamic segmentation

Automatically enforces policies for users, devices, and applications across wired and wireless networks.

Wi-Fi optimization

Aruba ClientMatch uses AI to steer traffic to the best AP while Aruba AirMatch dynamically allocates RF resources to improve coverage and eliminate gaps.

Application assurance

Aruba Air Slice dynamically allocates and tunes radio resources to ensure application service levels and optimize the user experience.

Flexible deployment

The 503 Series APs can be deployed in campus, branch, and remote locations and with cloud-based or on-prem management.
