4.1 Observed Problem
Problem statement 1
- There are a series of initiatives in the automotive industry that will touch the mobile environment
- There is work going on in the mobile/IoT industry that will need to interoperate with automobiles
- It is important for all not to waste resources by “reinventing the wheel”
- Use good protocols that already exist and are deployed
- There are a number of one-to-one company level programs underway, there is NOT a conversation happening at the industry-to-industry level to insure standards-based interoperability and reduce fragmentation of protocols across automotive interacting with IoT and mobile services
- The overall needs of the automotive industry are not being translated into mobile/IoT industry developments – harmonization of requirements and solutions between the mobile and the automobile environments. What are the problems the automotive industry are trying to solve?

- Operators and automakers could be forced to the sidelines where consumer touch, data collection and ownership are no longer future revenue sources
- Existing automotive approach of proprietary implementations is no longer working
Problem statement 3 -
