Multifunctional connectivity for home and small branch offices

The multifunctional 203R Series remote APs support both wall-box and desk-mount deployments, delivering secure and fast 802.11ac wireless and wired network access to corporate resources.

Easy to set up, easy to use

With no IT support required, the 203R Series APs deliver remote access point (RAP) benefits from the convenience of a small office or home.

Policy-based access control

Dynamic Segmentation enforces real-time, device-level access policies on Aruba wired and wireless networks.

Built-in Bluetooth Low-Energy (BLE) radio

Provides location-based services with BLE-enabled mobile devices receiving signals from multiple Aruba beacons at the same time.

Top-located USB port for support of USB cellular modem

The 203R Series access point enables the use of cellular modems to provide either backup or primary internet connectivity for remote access point (RAP) support and for client WLAN access, via a USB port located on the top of the access point for maximum flexibility.

Flexible radio architecture

The 203R Series APs flexible software configuration allows it to seamlessly switch between modes where the radio resources are either combined in a single 2×2 radio or separated into two 1×1 radios.

Securely work from home

Compact and cost-effective, the 203R Series APs offer a variety of enterprise-class features giving remote workers the same high-quality Wi-Fi 5 experience they get at corporate headquarters.

Compact, cost-effective access points that work from anywhere

Delivering Wi-Fi 5 connectivity (802.11ac, Wave 1), the 203R Series APs are software-configurable to operate in either 1×1 dual radio mode or 2×2 single radio mode. Easily deployed as a wall-mounted or desk-mounted access point, it’s perfect for home offices and small branch offices.

Highly secure and reliable when you’re working from home

The 203R Series APs span wired and wireless networks with role-based policies for users, devices, and applications. This flexible access point extends corporate resources to remote locations by establishing site-to-site VPN tunnels to the data center.

Choose your deployment and operating modes

Aruba network management and operations, including deployment, monitoring, and orchestration tools via modern cloud and on-premises software, provide maximum flexibility.
