1. A tracking system comprising a tracking proxy, said proxy comprising:
- a local area interface for communication with at least one container monitoring device in a wireless local area associated with the proxy,a processor for receiving monitoring device data and using it to generate a report messages, anda remote communication interface for loading the report message to a remote host;
the processor inserting geographical location data in the report message;
the processor performing bi-directional communication with a monitoring device;
the processor performing remote configuration of a monitoring device; and
a tracking gateway for receiving report message from the tacking proxy,the tracking gateway uploading tracking information based on received report messages to a tracking application,the tracking gateway route the tacking information via multiple redundant routes.

Abstract
Monitoring device modules (10) in containers on a ship are polled by a tracking proxy (12). Monitoring data is thus captured, and the proxy 12 can ascertain in real time that the correct group of containers is present. The proxy (12) also transmits higher-value report messages with relatively low bandwidth via a satellite communication system (13) to a gateway (15). The gateway (15) routes the messages on to various systems such as tracking centers. Also, the gateway (15) regularly polls and authenticates the distributed tracking proxies (12) within its group.
