Mass transit passengers now expect to have services that give them the freedom to Bring Their own Devices (BYOD). Operators see the potential to increase ridership with on-board entertainment that also brings the compelling opportunity for additional revenue generation from paid services and from advertising. However, it is very important to carefully assess the technologies available for possible pitfalls that slow development or can cause operational issues down the road. A main concern is that many of these systems are based on varying and proprietary technologies. Proprietary-based systems do not provide the compatibility necessary to facilitate interoperability and long deployment life.
