Vehicle Communications Landscape Has Changed
Over Time - Situation Today and in Hindsight
• Slow but steadily development

– Various proprietary fleet management systems
– None has been widely successful
• • First telematics hype in the late 1990ies
– … and disillusionment in 2002

• Basically due to immature technology and weak business models
– Single service portfolio as a main roadblock
–Vertical / silo applications
– Cooperation between various industries was a challenge
– Pre-GPRS data connectivity way too complicated and inflexible
