Custom Antenna Adaptation for Wired-Free Modern Security Monitoring Devices
Multi-combination cellular and WiFi antennas inside smart routers face prominent crosstalk troubles between different frequency bands, making isolation optimization a core design point. Household dual-band WiFi routers separate 2.4GHz and 5GHz antenna layout to eliminate mutual signal suppression and remove indoor coverage dead spots.Outdoor industrial CPE smart routers integrated with LTE and 5G modules adopt spaced external composite antennas. Such structural design effectively cuts off inter-band interference, enabling stable high-speed network output for remote mountain villages and temporary construction site networking needs.
