12 Goals Communications and RFID-related technologies Develop mechanism to continuously monitor and communicate between the mobile platform and the central SmartPort data clearinghouse in an authenticated and secure way Develop, implement, and evaluate RFID technology within the trusted corridor 12

13 Communications technologies for the continuous monitoring Focus on container to central SmartPort data clearinghouse. Trend Growing demand and use of broadband mobile Internet services Long stays on railways provide revenue opportunity for communications companies and rail provider Broadband Internet access technologies for customers on high speed trains are developing, especially in Europe These commercial systems face many of the same technical challenges Opportunity to Leverage their lessons learned and technologies for this system Reduce deployment cost by leveraging commercial implementations 13

14 Communications technologies for the continuous monitoring Assumption Avoid having a connection the central system built into each container feed the data back along the train to one or a small number of backhaul systems. Key elements Container system Inter-container communications Backhaul communications 14

15 Communications technologies for the continuous monitoring Train Environment Tough Electrical environment harsh: Train systems not typically designed to provide clean power for computer and communications systems Computer and communications systems may require an interrupted supply Physical clearance issues for attached antennas High vibration environment May require mechanical isolation Thermally challenging Heat can be a major issue in various Keep maintenance schedules to a minimum Long service life deployment of technology that might only be expected to last a couple of years may not be the best approach, especially if the deployment can only be done during a periodic and infrequent refit cycle. 15

16 Communications technologies for the continuous monitoring Options for inter-container communications Copper (TP or coax) Inexpensive Needs rugged connector Needs manual connections Fiber Very high capacity Connector issues Environmental issues Radio Links Easy to deploy Inexpensive cost decreasing Ad-hoc networking technology maturing Our focus will be on this solution 16
