Enable a path for automakers and operators Mobile Network Operators (MNOs) to encourage communications interoperability across automotive and wireless industries.
...
- The auto industry wants to ensure openness and mobile device interoperability with the car telematics systems
- Automakers run the risk of becoming a “dumb device” with no control over user data
- Operators MNOs 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
...
- Low data byte transmission with allowance for client to sleep (i.e., non-continuous communication)
- Suitable for constrained devices (hence reduced footprint for reduced CAPEX for car manufacturers)
- Several objects can be reported in one message using simple content types like TLV, JSON and single objects with simple text content type
- Ability to support a range of solutions through pre-defined objects (connected car objects/resources)
- Client (connected car) could send notifications to server based on defined trigger events e.g. periodic reporting, reporting upon a change of value, reporting based on thresholds reached. This is key as it gets past the poll and/or notification model
- LWM2M by default works with 3GPP technologies hence easier integration with telecommunication operatorsMNOs
6.3.3 Core Interfaces
The core interfaces between the server and the client are categorized into:
