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

2. 2 RATP: Paris Subway & Bus RATP wireless employee projects RATP intelligent bus project Challenge 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) Delivering real-time operational information to employees in stations and in buses Applications Customer information, profitability, staff management, maintenance, security, etc.

3. 3 The Pain Point Information Headache? Wireless broadband is overwhelming for mobile users  Too much information  Too cumbersome to surf & search  Too much administration Painkiller Too much Information 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

4. 4 Information 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 ... Context Engine On-site Intelligent Filtering An extra layer of computing intelligence is required in order to deliver an effective solution for mobile workers: Context-Aware Services

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

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