R3X30A HPE Apollo 35 v2 2-Ports Ethernet Pci Express Adapter

HPE R4H18A — Aruba AP-575 Outdoor WiFi 6 

The HPE R4H18A (Aruba AP-575) is a purpose-built outdoor Wi‑Fi 6 (802.11ax) access point engineered to deliver resilient, high-capacity wireless connectivity in harsh external environments. Designed for campuses, stadiums, parking areas, transit hubs, and distributed public venues, this ruggedized AP combines multi‑gigabit performance, integrated IoT radios, enterprise-grade security, and streamlined deployment options to support dense client populations and modern Internet of Things (IoT) use cases.

Detailed technical overview

Radio architecture and performance

The AP‑575 is a dual‑radio device that separates client traffic across a 5 GHz radio and a 2.4 GHz radio. The 5 GHz radio implements 4x4 MIMO to provide improved spatial streams for high‑throughput clients, while the 2.4 GHz radio runs 2x2 MIMO to maintain broad legacy compatibility and longer-range coverage.

Key wireless technologies included

• 802.11ax (Wi‑Fi 6): OFDMA for efficient multi-user scheduling, target wake time (TWT) for improved battery life on IoT devices, and enhanced modulation for higher per‑user data rates.
• MU‑MIMO: Improves simultaneous client capacity on the 5 GHz radio (4x4).
• Beamforming: Directional signal focus for stronger client connections at range.
• Enhanced roaming and airtime fairness: Smooth handoffs and better experience in dense environments.

Throughput and practical capacity

Real‑world performance depends on environment, channel plan, and client capability. The AP‑575 supports multi‑gigabit aggregate on‑air rates from its combined radios and is optimized to handle many concurrent clients typical of stadiums, campuses, and large public venues. When planning capacity, consider a mixture of 5 GHz‑capable clients (to leverage 4x4 streams) and 2.4 GHz legacy devices.

Integrated IoT radios and use cases

A major value proposition of the AP‑575 is its built‑in Bluetooth 5 and 802.15.4 radios (Zigbee compatible), which allow the access point to function as an IoT gateway. This dramatically reduces infrastructure complexity when deploying location services, beacons, asset tracking, environmental sensors, and low‑power IoT endpoints.

Typical IoT deployments enabled

1. Asset tracking and real-time location systems (RTLS) in transportation terminals or campuses.
2. Proximity and location-based marketing in retail or stadium concourses using Bluetooth beacons.
3. Environmental monitoring and sensors using 802.15.4 / Zigbee networks bridged by the AP.

Physical design and environmental resilience

Rugged housing and IP sealing

The AP‑575’s enclosure is engineered for outdoor use: waterproof seals, corrosion‑resistant materials, and an internal thermal design that tolerates wide temperature swings. These design choices minimize service interventions and extend operational life in exposed deployments.

Mounting and mechanical options

• Wall mount and pole mount brackets for flexible installation on buildings, light poles, and street furniture.
• Cable gland provisions and locking fasteners to preserve ingress protection and reduce cable strain.
• Optional accessories for vandal resistance and additional weatherproofing.

Power and connectivity

Support for Power over Ethernet (PoE) simplifies installation by enabling both data and power delivery over a single Ethernet cable. The AP‑575 is compatible with common PoE standards and supports remote power cycling for maintenance and recovery.

Recommended power and cabling practice

• Use IEEE‑compliant PoE midspans or PoE switches to guarantee proper power delivery under full load.
• Employ weatherproof-rated Ethernet cabling and connectors for long-term reliability.
• Observe distance limits for PoE and use local repeaters or fiber uplinks for extended runs.

Enterprise security and management

Authentication, encryption, and standards

The AP‑575 integrates Aruba’s security stack, providing enterprise authentication options (802.1X, RADIUS), WPA3 encryption, secure management channels, and role‑based policies. Out‑of‑the‑box compatibility with ArubaOS and Aruba Central ensures unified policy enforcement and simplified credential management.

Network segmentation and guest access

Support for virtual LANs (VLANs), dynamic segmentation, and captive portal workflows allows IT teams to carve separate guest, employee, and IoT networks without additional overlay infrastructure.

Monitoring, analytics and cloud management

Use Aruba Central or on‑prem ArubaOS controllers for centralized monitoring, firmware management, client analytics, and location services. These tools offer troubleshooting dashboards, proactive alerts, and historical reporting to optimize coverage and throughput.

Deployment scenarios and site planning

Coverage planning for different venue types

The AP‑575 is particularly well suited for: large outdoor campuses, parking structures, transit platforms, stadium concourses, and municipal Wi‑Fi projects. When planning deployments, combine RF simulations with on‑site surveys to determine antenna placement, backhaul requirements, and PoE provisioning.

High-density arenas and stadiums

In stadiums and arenas, deploy AP‑575 units with overlapping coverage zones and carefully tuned power and channel plans to prevent co-channel interference. Strategically place APs in concourses and high-traffic gathering areas to handle peak loads during events.

Linear coverage for roadways and transit

For linear environments like sidewalks, transit platforms, and parking lanes, pole-mount installations with directional planning ensure consistent coverage and handover behaviors for moving clients.

Backhaul and connectivity considerations

• Use fiber uplinks for multi‑gigabit backhaul in dense deployments.
• Aggregate traffic at PoE switches with SFP ports to preserve wired throughput.\li>
• Plan for redundant uplinks where service continuity is critical.

Compatibility, SKUs, and ordering information

SKU details and regional variants

The AP‑575 family includes regionally compliant SKUs for regulatory and frequency band differences. When ordering, confirm the SKU matches your country/region to ensure regulatory compliance and appropriate antenna tuning.

Model selection checklist

• Confirm regulatory region SKU (US, EU, IL, JP, etc.).
• Verify whether you require TAA or other procurement compliance for public-sector bidding.
• Check warranty and support entitlements at time of purchase.
