AI Technical Summary
Wireless tracking devices mounted on containers are prone to physical damage and vandalism due to harsh conditions, leading to communication failures and loss of location tracking capability.
A dual-antenna system with an external and internal antenna configuration, where an RF switch selectively couples either antenna to a transceiver based on signal strength, ensuring continuous communication by switching to the internal antenna in case of external antenna damage or sabotage.
The system enhances security and reliability of container tracking by detecting potential modification events and reporting the location to a remote device, even when the external antenna is compromised.
