Industrial 4G Router Technical Analysis: Questions & Answers
Q1: “Why do industrial routers need dual SIM card slots?”
Based on the technical specifications, dual SIM design provides network redundancy. When one carrier’s signal fails, the router automatically switches to the backup SIM card, ensuring continuous connectivity – critical for industrial applications where downtime isn’t acceptable.
Q2: “What’s the significance of -35°C to +75°C operating temperature range?”
This wide temperature range is essential for industrial environments. The specifications show all models support this range, enabling deployment in harsh conditions from cold storage facilities to hot manufacturing plants – a key differentiator from consumer routers.
Q3: “How does IP30 protection rating impact industrial applications?”
The IP30 rating, mentioned across all models, provides solid protection against objects larger than 2.5mm while allowing necessary ventilation. This balance of protection and thermal management is crucial for industrial environments without requiring additional cooling systems.
Q4: “Why include both RS232 and RS485 interfaces?”
According to the specifications, this dual-interface design supports both short-range (RS232) and long-range (RS485) serial communications. This versatility enables connection to various industrial equipment, from legacy systems to modern sensors.
Q5: “What makes these routers specifically ‘industrial’ versus standard 4G routers?”
The technical documents reveal multiple industrial-grade features: metal housing, wide voltage input (5-36V), EMC protection (15KV ESD), extensive protocol support (Modbus, MQTT), and MTBF ≥100,000 hours. These specifications ensure reliability in demanding industrial environments.
