<h3 data-start="430" data-end="494"><strong data-start="433" data-end="492">The Role of Heterogeneous Networks in Smart Factory 4.0</strong></h3>
<p data-start="496" data-end="992">Smart Factory 4.0 represents the next evolution of manufacturing, integrating advanced technologies like the Internet of Things (IoT), artificial intelligence (AI), and cloud computing. A key component of this transformation is the use of heterogeneous networks, which enable seamless communication between machines, sensors, and control systems. These networks are essential for optimizing production efficiency, ensuring real-time data exchange, and supporting cloud migration strategies.</p>
<p data-start="994" data-end="1378">In modern smart factories, diverse communication protocols and devices must coexist within a unified infrastructure. Heterogeneous networks combine wired, wireless, and power line carrier (PLC) technologies to meet different operational needs. These networks ensure high-speed data transmission, low latency, and reliable connectivity while maintaining security and flexibility.</p>
<h3 data-start="1380" data-end="1472"><strong data-start="1384" data-end="1470">Classification and Key Technologies of Heterogeneous Networks in Smart Factory 4.0</strong></h3>
<p data-start="1474" data-end="1623">Heterogeneous networks in Smart Factory 4.0 can be classified into three main types based on their communication technologies and applications:</p>
<h4 data-start="1625" data-end="1663"><strong data-start="1629" data-end="1661">1. Industrial Wired Networks</strong></h4>
<p data-start="1664" data-end="1816">Wired networks provide high-speed and stable communication, making them suitable for critical manufacturing applications. Common technologies include:</p>
<p><strong data-start="1820" data-end="1841">&#8211; Fieldbus Systems:</strong> Standards such as Modbus, PROFIBUS, and CC-Link enable reliable communication between industrial devices.</p>
<p><strong data-start="1952" data-end="1981">&#8211; Real-Time Ethernet (RTE):</strong> Advanced protocols like EtherCAT and PROFINET RT enhance real-time data exchange, improving automation precision.</p>
<p><strong data-start="2100" data-end="2127">&#8211; Optical Fiber Networks:</strong> These provide ultra-fast, high-capacity data transmission, reducing interference in industrial environments.</p>
<h4 data-start="2240" data-end="2288"><strong data-start="2244" data-end="2286">2. Industrial Wireless Networks (IWNs)</strong></h4>
<p data-start="2289" data-end="2440">Wireless networks offer flexibility and scalability, making them ideal for mobile equipment and remote monitoring. Key wireless technologies include:</p>
<p><strong data-start="2444" data-end="2468">&#8211; Wi-Fi and Bluetooth:</strong> Commonly used for machine connectivity and short-range communication.</p>
<p><strong data-start="2543" data-end="2563">&#8211; Zigbee and LoRa:</strong> Low-power communication technologies used for IoT-enabled sensor networks.</p>
<p><strong data-start="2643" data-end="2659">&#8211; 5G Networks:</strong> Provide ultra-low latency and high bandwidth for real-time factory automation.</p>
<p data-start="2742" data-end="2978">Despite their benefits, wireless networks must address challenges like signal interference, security risks, and connectivity reliability. Smart factories are now implementing AI-based network optimization to mitigate these issues.</p>
<h4 data-start="2980" data-end="3031"><strong data-start="2984" data-end="3029">3. Power Line Carrier (PLC) Communication</strong></h4>
<p data-start="3032" data-end="3415">PLC technology utilizes existing power lines for data transmission, reducing the need for additional wiring. This method is advantageous in retrofitting older manufacturing plants. However, signal degradation and interference can impact performance, necessitating advanced modulation techniques like Orthogonal Frequency Division Multiplexing (OFDM) to enhance reliability.</p>
<h3><strong data-start="3421" data-end="3495">SDN- and EC-Based Heterogeneous Networks Framework for Smart Factories</strong></h3>
