Scalability of vehicular M2M communications in a 4G cellular network

Automated machine-to-machine communication over cellular wireless networks is likely to become a major source of traffic in future communication networks, e.g., for automated monitoring of infrastructure. The long-term evolution wireless network has been designed to provide enhanced capacity; however, the information rate density that can be accommodated is limited. Here, we report limits to the scalability of automated automobile monitoring systems in terms of delay and blocking rates versus vehicle density. The results of numerical modeling were found to agree well with approximate analytical results.
