A comparative Analysis of mmWave vs LTE technology for 5G Moving Networks

Mobile users in vehicular environments such as trains, buses and other public transportation vehicles suffer from the low quality signal from the outside wireless network. The rapid growth in the deployment of LTE femtocells for indoor use and their benefits have led many authors to propose using them even in vehicles, implementing the so-called Moving Networks. This paper shows that the use of pure LTE femtocells exhibits relevant issues in terms of interference and consequently performance in a realistic use. In order to overcome these issues, we propose to adopt the millimeter Wave technology in the Moving Networks, creating the Hybrid Mobile Femtocells. In the paper we discuss the concerns arising from applying mmWave communications at 60 GHz inside vehicles and we provide a new throughput analysis in order to benchmark our proposed architecture to the existing implementations.
