High — Reliability low — Latency cellular network communication solution for static or moving ground equipment control

摘要

Implementation of remote equipment data communication channel sometimes is problematic due to the network channel cost or unduly low service quality. An expanding mobile cellular network data transfer service facilitates cheaper wireless solutions for the needs of various data transfer, including mobile ground objects. However, the cellular networks cannot be used in critical and real time data transmission networks due to the unstable and non-predictable service quality. We introduce a Parallel Redundancy Protocol (PRP) as a solution that can be used to facilitate the stationary and moving equipment robust data transfer needs by using the cellular networks. In this research, a software PRP implementation was used to build redundant wireless link without any switchover time at all. Then the service quality in 3,5G networks was experimentally investigated with and without PRP implementation. The testing was done both for stationary and moving ground based equipment. Further, 3G B1 (2100 MHz), 3G B8 (900 MHz) and 4G modes are experimentally investigated to recommending the network mode (or modes combination) selection for the PRP implementation.
