The **W2AP-G1A-R2/UL** is a high-performance **Industrial Wireless Access Point** manufactured by **Patlite**. It is designed for harsh industrial environments, specifically used to bridge communication between factory floor devices (like signal towers and sensors) and IT networks. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Model** | W2AP-G1A-R2/UL | | **Wireless Standard** | IEEE 802.11a/b/g/n (Dual Band) | | **Frequency Bands** | 2.4 GHz and 5 GHz | | **Wired Interface** | 10/100/1000Base-T (Gigabit Ethernet) | | **Power Supply** | 24V DC or PoE (Power over Ethernet) | | **Compliance** | UL Listed, FCC, CE | | **Protection Rating** | IP20 (Indoor/Cabinet use) | --- ### 2. Core Electronic Components & Architecture The hardware architecture is optimized for low latency and high reliability in environments with significant electromagnetic interference (EMI). #### A. Radio Frequency (RF) Module * **Dual-Band MIMO:** Uses Multiple-Input Multiple-Output technology to improve signal stability in metal-heavy environments (factories) where multipath interference is common. * **Antenna System:** Features high-gain antennas to ensure coverage over large shop floors. #### B. Processing & Memory * **Industrial CPU:** Equipped with a dedicated network processor to handle high-speed data packet routing without bottlenecks. * **RAM/Flash:** Sufficient onboard memory to maintain a stable connection for up to dozens of simultaneous client devices (like Patlite WD series wireless transmitters). #### C. Power Circuitry * **Dual Input:** Supports a standard **24V DC** terminal block common in PLC cabinets. * **PoE (802.3af):** Allows the unit to be powered via the Ethernet cable, simplifying installation in high-up locations where power outlets are unavailable. --- ### 3. Functional Capabilities * **Security Protocol:** Supports WPA/WPA2-PSK (AES) and WPA/WPA2-Enterprise for secure industrial data transmission. * **Device Management:** Features a web-based GUI for configuration and SNMP support for integration into Network Management Systems (NMS). * **Roaming:** Supports seamless roaming for mobile industrial equipment (like AGVs) moving between different access point zones. --- ### 4. Typical Application Circuit In a standard industrial setup, the electronic connection follows this logic: ```text [Signal Tower] --(Wireless)--> [W2AP-G1A-R2/UL] --(Ethernet/PoE)--> [Industrial Switch] --> [Server/PC] | ^ |_______________________________| (2.4GHz / 5GHz) ```
