Abstract

The mobile operation and wireless application of smart factory have many requirements for wireless transmission, such as low latency, high bandwidth, massive connections. 5G networks can meet the above performance requirements, mainly due to the technological evolution of 5G wireless technology and network architecture. This paper proposes a high-performance 4G virtual wireless private network solution, which innovatively applies MEC technology and network Slicing technology to the 4G network. This solution utilizes operators'4G public network frequencies and existing mature and low-cost Small cell equipment to build a secure 4G wireless virtual private network, which can meet the requirements of end-to-end delay, bandwidth and massive-connection under the mixed conditions of HRLL service, wireless video, sensor data and other services at the same time.
