In order to achieve higher-level autonomous driving, Vehicle-to-Everything (V2X) communication is indispensable for observation of surrounding vehicles by remote center. In this paper to attain safe driving by remote observation in a challenged communication environment where only conventional low speed LTEs by carriers are available, a new multi-links method which is based on various carrier’s communication links with different frequency bands is introduced to increase the communication speed by single communication link. A mobile router integrates the carrier links into V2X communication using bi-directional links to communicate with a remote router acting as a VPN network. Thus, higher throughput V2X communication can be realized. In this work, system design and implementation of this method are provided, and its performance evaluation is carried out by constructing and executing a prototype to demonstrate its performance.
