AI Technical Summary

Technical Problem

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.

Method used

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.

Benefits of technology

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.

Abstract

To provide an antenna and a container having an antenna. [Solution] A device, a system, and a method of operating the device are provided. In one aspect, the device includes an external assembly including an external antenna and an internal assembly. The internal assembly includes an internal antenna, a transceiver, and a radio frequency (RF) switch, the RF switch being coupled to the transceiver, the internal antenna, and the external antenna. The RF switch is configured to selectively couple at least one of the external antenna or the internal antenna to the transceiver. The external antenna is coupled to the RF switch through at least one conductor.
