The **M2AP-H1-R/CE** is a high-performance industrial wireless access point developed by **Hirschmann** (a Belden brand). It is designed specifically for demanding industrial environments such as automation, transportation, and oil & gas. --- ### 1. Technical Specifications Overview Below are the primary electronic and network specifications for the device: | Feature | Specification | | :--- | :--- | | **Wireless Standard** | IEEE 802.11a/b/g/n/ac (Wi-Fi 5) | | **Frequency Bands** | 2.4 GHz and 5 GHz (Dual Band) | | **MIMO Support** | 3x3 MIMO (Multiple Input Multiple Output) | | **Data Rate** | Up to 1.3 Gbps (on 5 GHz band) | | **Ethernet Ports** | 2 x 10/100/1000BASE-TX (RJ45) | | **Operating Voltage** | 24 VDC (Typical range: 18V to 60V DC) | | **Power over Ethernet** | PoE+ (IEEE 802.3at) | --- ### 2. Key Electronic Components & Design The "H1-R/CE" designation refers to specific hardware configurations tailored for the European (CE) market and ruggedized applications. #### A. Power Supply System * **Redundant Inputs:** The device supports dual power inputs. If one power source fails, the secondary takes over without disrupting the wireless signal. * **Galvanic Isolation:** The internal circuitry is protected against voltage spikes and electromagnetic interference (EMI) common in industrial motor environments. #### B. Radio & Antenna Interface * **Antenna Connectors:** Typically uses **N-type** connectors which are physically robust and offer low signal loss for external antenna attachments. * **Advanced Encryption:** Includes dedicated hardware processing for WPA3 and AES encryption to ensure security without sacrificing throughput. #### C. Industrial Ruggedization * **IP Protection:** Usually rated **IP67**, meaning the internal electronics are completely protected against dust and temporary immersion in water. * **Temperature Tolerance:** Designed to operate in extreme ranges, often from **-40°C to +70°C**. * **Shock & Vibration:** Electronic components are soldered and braced to withstand the vibrations found on trains or heavy machinery (compliant with EN 50155). --- ### 3. Use Case Scenarios 1. **Manufacturing:** Connecting Automated Guided Vehicles (AGVs) to the central network. 2. **Transportation:** Providing Wi-Fi on trains or trackside communications. 3. **Hazardous Areas:** Monitoring sensors in remote locations where wired infrastructure is impossible. ---
