The **W2AP-A35-R/UL** is a high-performance, outdoor industrial-grade wireless access point, often rebranded or integrated into specific industrial networking solutions (such as those by Advantech or similar telecommunications OEMs). Below is a breakdown of its technical specifications and electronic characteristics. ### Technical Specifications Overview | Feature | Specification | | :--- | :--- | | **Model Number** | W2AP-A35-R/UL | | **Form Factor** | Outdoor Ruggedized IP67/IP68 Enclosure | | **Standard** | IEEE 802.11a/b/g/n/ac (Wi-Fi 5) | | **Bands** | Dual-band (2.4 GHz & 5 GHz) | | **Interface** | 1 x 10/100/1000Base-T (RJ-45) | | **Power Supply** | PoE (Power over Ethernet) IEEE 802.3at/af | | **Certifications** | UL Listed, FCC, CE, RoHS | --- ### Key Electronic Components & Systems #### 1. Radio Frequency (RF) Frontend * **MIMO Technology:** Usually supports **2x2 or 3x3 MIMO** (Multiple Input, Multiple Output) to improve throughput and signal reliability in noisy environments. * **Power Amplifiers (PA):** Integrated high-gain amplifiers to extend signal range for outdoor deployment. * **Antenna Connectors:** Typically features N-Type or RP-SMA connectors protected by weather-sealed gaskets. #### 2. Processing and Logic * **Main SoC:** Utilizes a high-efficiency network processor (typically Qualcomm Atheros or Broadcom) capable of handling high-speed traffic encryption and routing. * **Memory:** * **RAM:** 128MB to 256MB (DDR3) for packet buffering. * **Flash:** 16MB to 32MB for firmware storage and configuration. #### 3. Power Management * **PoE Controller:** Since it is an outdoor unit, it relies on **Power over Ethernet (PoE)**. The internal circuitry includes a DC-DC converter to step down the 48V-54V PoE input to the lower voltages (3.3V, 1.8V, 1.2V) required by the logic chips. * **Surge Protection:** Includes ESD (Electrostatic Discharge) protection up to 6kV and surge protection to prevent damage from lightning or power spikes common in outdoor setups. #### 4. Environmental Ruggedization * **Thermal Design:** The internal electronics are mounted to a metal heat-sink chassis to dissipate heat without requiring internal fans (passive cooling). * **Operating Temperature:** Designed to operate between **-40°C to +70°C**. --- ### Safety and Compliance ("UL" Suffix) The "UL" in the part number indicates that the electronic components and the assembly meet **Underwriters Laboratories** safety standards. This is critical for industrial applications because: * It ensures the housing is flame-retardant. * It verifies that the electrical insulation and grounding are sufficient to prevent fire or electric shock. * It permits use in specific hazardous or regulated industrial zones.
