Interconnecting mobile consumer devices across fleets
Designing, developing and introducing "automotive-grade" LTE upgrade hardware for in-car WLAN
Initial situation and problem
- The client requires LTE-based connectivity hardware that can be used across fleets and meets all automotive requirements
- The hardware is intended to give consumer devices the ability to connect stably via mobile WLAN
- The hardware is intended to act as an "over-the-air" (OTA) managed access point
mm1 approach and solution
- High-level specification of the HW/CAPWAP implementation incl. OTA management of device & FW
- Perform international supplier selection
- Manage HW development incl. optimize the performance and robustness of MIMO antennas for all European LTE frequency bands
- Develop cross-vehicle antenna guidelines
- The manufacturer became capable of developing automotive hardware incl. KBA approval
- The first 100Mbit automotive WLAN solution in the world was launched
- High session stability, even at high speeds and quick cell change via WLAN (and connection via German mobile network)
