2D LOS/NLOS urban maps and LTE MIMO performance evaluation for vehicular use cases

摘要

The recent developments in automotive industry are tending to satisfy the mobile users' demands for low delay and high bandwidth data to current and future cellular networks. To fulfil the needs of mobile users on mobility, the proper design of wireless communication is necessary. The design of wireless links without prior knowledge of obstructions, base station locations, and cell load is not realistic and challenging. To address this issue we implement realistic Line of Sight (LOS)/Non-Line of Sight (NLOS) urban maps and conduct field measurements in Long Term Evolution (LTE) 1800 MHz live network. The campaign is supported by knowing crucial information such as base station locations. The field measurements are carried out on-board of a commercial small vehicle which causes up to 3.9 dB penetration loss. The focus of this paper is on performance evaluation of diversity and multiplexing by Rank Indicators (RIs).
