The **W2AP-D23-R/CE** is a high-performance **Industrial Wireless Access Point** manufactured by **Westermo**. It is designed specifically for harsh environments such as trackside railway applications, mining, and maritime industries. --- ## 1. Core Hardware Specifications The internal electronics are engineered for reliability and high throughput in extreme conditions. | Component | Specification Details | | :--- | :--- | | **Wireless Standard** | IEEE 802.11ac (Wi-Fi 5) | | **Radio Chains** | 3x3 MIMO (Multiple Input, Multiple Output) | | **Frequency Bands** | Dual-band 2.4 GHz and 5 GHz | | **Data Rate** | Up to 1.3 Gbps (5 GHz) + 450 Mbps (2.4 GHz) | | **Processor** | Industrial-grade SoC optimized for packet routing | | **Ethernet Ports** | 2 x 10/100/1000 Base-T (Gigabit) | --- ## 2. Key Electronic Features ### A. RF Performance (Radio Frequency) * **High Sensitivity:** The device features advanced low-noise amplifiers (LNA) to maintain signal integrity over long distances. * **Beamforming:** Uses electronic phase shifting to direct the signal toward the client device, improving range and reducing interference. ### B. Power & Protection * **PoE Support:** Power over Ethernet (IEEE 802.3at) allows for a single cable to handle both data and power, simplifying installation in remote locations. * **Galvanic Isolation:** The internal circuitry includes high-level isolation to protect the electronics from power surges and electromagnetic interference (EMI). ### C. Physical Interface * **Antenna Connectors:** Typically uses QMA or N-type connectors designed for vibration resistance. * **M12 Connectors:** Often utilizes M12 circular connectors instead of standard RJ45 to ensure waterproof and vibration-proof data connections. --- ## 3. Environmental Durability The electronic components are selected and mounted to withstand conditions that would destroy consumer-grade hardware. * **Operating Temperature:** Designed to function between **-40°C to +70°C**. * **Ingress Protection:** Rated **IP66**, meaning the electronics are completely protected against dust and high-pressure water jets. * **Shock & Vibration:** Tested to EN 50155 standards, ensuring the solder joints and internal boards do not crack under constant mechanical stress. --- ## 4. Logical/Software Architecture The hardware runs **WeOS (Westermo Operating System)**, which provides: 1. **Cybersecurity:** Integrated firewall, VPN support (IPsec/OpenVPN), and 802.1X authentication. 2. **Redundancy:** Support for fast roaming and RSTP (Rapid Spanning Tree Protocol) to ensure network uptime.
