1. Wi-Fi applications in Paris Urban Transport Metro and Buses Régie Autonome des Transports Parisiens - RATP J. Richert Appear Networks X. Aubry

2. RATP: Paris Subway & Bus Business With 44300 employees, RATP operates 4 networks : metro (14 subway lines), bus (4000 buses over 317 bus lines), RER (2 lines express train), tramway (2 lines) RATP intelligent bus project Challenge Delivering real-time operational informationto employees in stations and in buses Applications Customer information, profitability, staff management, maintenance, security, etc. RATP wireless employee projects

3. The Pain Point Too much Information Information Headache? • Wireless broadband is overwhelming for mobile users • Too much information • Too cumbersome to surf & search • Too much administration • Information push and data filtering are required • Pushing relevant data to the right users • Easy to use graphical user interface • Simplified and centralized service administration Painkiller

4. On-site Intelligent Filtering • Information push means new constraints on information filtering • Only the right data should be pushed • Relevance of information is highly dependant on the workers' situation • Time • Location • Role • Type of device • Available bandwidth • ... Information Filtering • An extra layer of computing intelligence is required in order to deliver an effective solution for mobile workers: Context Engine Context-Aware Services

5. Relevant Information Immediately Available Wireless Network No Coverage Easy Access to Data In One Single Click Current Information Stored for Offline Use User Recognition Context Assessment Delivery of Relevant Data

15. Lessons Learned Return on Investment • The impact of an intelligent wireless communication platform on your bottom-line depends on • 4 Golden Rules • Focus on workforce efficiency before looking at new possible revenues: cost savings today are better than revenues tomorrow! Rule Nb 1 • Manage IT cost by selecting a solution that has an impact on the total cost of ownership of your fleet of mobile devices: watch the TCO. Rule Nb 2 • Retain flexibility / adaptability by using open standard solutions that can work with multiple IP networks and heterogeneous device fleets. Rule Nb 3 • Focus on employee compliance and customer satisfaction by adopting solutions with high ergonomics: no usage, no impact! Rule Nb 4
