Abstract:This report assesses the technological options available to provide wireless broadband service on the commuter rail in Utah. Technologies are identified and evaluated for realizable wireless architecture capable of handling large volumes of voice, video and data communications in a highly mobile setting. Several existing WiFi deployments are examined and compared in terms of in-train WiFi service and the train-to-ground backhaul. Newly emerged technologies are also considered and evaluated. WiMAX backhaul is found to be the most attractive for the following reasons: Higher Network Bandwidth, Lower Network Latency, Low Cost of maintenance, and Proven track record. Satellite communication is found to be desirable for backup and emergency operations. The scope of this report is focused on technologies for the physical wireless data link, but also recommends inclusion of a long-term service manager to ensure quality, stability and security of the public WiFi service. Ideally this should be done by a service provider with experience managing open, public internet access points. Some vendors offer complete turnkey service for deploying WiFi on rail systems, including service management. Turnkey solutions are given a separate assessment in this report. Our final vendor assessments in each technology area are given as tables of numerical scores which can be found in Appendix 1.
