Open Interconnect Consortium (OIC)
5 / 10
• A single connectivity framework for IoT devices across multiple vertical markets
using common interoperable approach
• Secure and reliable device discovery
• Intelligently manages the flow of information, regardless of form factor, operating
system or service provider.
• OIC develops standards and open source code spanning multiple OSs and platforms
• Initial open source code available in Sept. 2014

V2X Standards/Building blocks
6 / 10
• LTE is increasingly being used to provide V2I connectivity
• DSRC provides connectivity on top of 802.11 PHY/MAC
• WAVE protocol provides resource management and
security
• Provides an abstraction layer for vehicle applications,
managing communication for multiple concurrent sessions
spanning all modes (V2V, I2V, I2I), and all methods of
transmission (LTE, radar, WiFi, etc.)
• V2X gateway for routing heterogeneous links
• Regulatory bodies endorse standards as component
building blocks within the overall framework
• Focus on safety applications and interoperability
• Spectrum issues

V2X and 5G
9 / 10
New requirements/services for V2X:
- Targeting 1 ms end-to-end latency (in the RAN)
- Ubiquitous coverage (no cell-edge)
- Flexible support for multiple V2X modes (V, P, I)
- High-data rate software services for the vehicle (> 1 Gbps)
Challenges:
- Centralized vs. distributed control
- Data management for V2X
- RF/Antenna design
- Infrastructure topology
