HPE R4E11A Aruba AP 387 Outdoor Wireless Access Point

Detailed Specifications

The HPE R4E11A is an Aruba 387 Series outdoor wireless access point, engineered to solve challenging point-to-point connectivity needs. It is specifically designed for enterprise environments requiring reliable, high-throughput links between buildings, such as connecting campus structures, remote offices, or temporary event sites up to 400 meters apart. The primary challenge it addresses is the need for multi-gigabit wireless bridging without the cost and complexity of trenching fiber, particularly in locations where physical cabling is impractical or impossible. At its core, this access point utilizes a sophisticated dual-radio system. A high-frequency 60 GHz 802.11ad radio delivers a primary data link with speeds up to 2.5 Gbps for maximum performance. This is paired with an 867 Mbps 5 GHz 802.11ac radio that provides an intelligent, automatic fallback connection. This resilience ensures the link remains stable during heavy rain or other atmospheric conditions that can affect the 60 GHz signal, delivering consistent uptime for critical operations. Built for deployment in harsh exterior environments, the R4E11A features a hardened, weatherproof chassis designed to withstand extreme temperatures, moisture, and wind speeds up to 165 mph. Its physical design includes sealed connector interfaces for robust protection against dust and water ingress. Management is flexible, with support for controller-managed (ArubaOS) and controllerless (InstantOS) modes, allowing it to integrate seamlessly into existing Aruba network infrastructures.
