1. A container position tracking and real-time management system for tracking the location of a container in association with a wired/RF communication network, the system comprising: a container tag including a sensor unit that monitors measurement information about environment within the container and whether the container is abnormal, and a communication unit that transmits container management information, including the monitoring results of the sensor unit and a container-specific address, to a reader through RF communication; the reader being installed at a vehicle or ship that transports the container and including a RF receiver module that receives the container management information from the container tag, wherein the communication unit sends the collected container management information at predetermined time intervals, and immediately sends results of events including an error of eSeal, an occurrence of abnormality including a temperature, humidity and pressure, and a possible danger of discharge of a battery, and wherein when communication transmission fails, the communication unit accumulates and stores contents that have not been sent in a memory unit and then sends the contents in a first place when communication resumes.
