V. Recommended Industry-Scenario Combinations

VI. Selection Pitfall Avoidance Guide

1. Frequency Band Mismatch: 5km long-distance communication using 2400MHz modules → Choose 900MHz band (2900016) + high-gain YAGI antenna (5606614) for better penetration and distance.
2. Antenna Type Error: Point-to-multipoint networking using directional antennas → Select omnidirectional OMNI antennas (2867623) for wide coverage of multiple devices.
3. I/O Channel Underestimation: 8 digital sensors using 4-channel DI module → Pick 8-channel variant (2901539) to avoid network segmentation.
4. Interface Incompatibility: MCX-interface wireless modules using SMA antennas → Ensure antenna interface matches module (e.g., 2700674 for MCX modules) to prevent signal loss.
5. Harsh Environment Neglect: Outdoor applications using non-IP-rated antennas → Select IP65/IP67-rated antennas (2867814/2701358) to resist dust and water.
6. Protocol Mismatch: RS485 sensors using standard wireless modules → Use protocol conversion module (1081818) to enable communication between RS485 devices and wireless networks.
