This document describes a methodology for virtual drive testing (VDT) of LTE-A vehicular environments as an alternative to physical drive tests. 3D ray tracing is used to generate dynamic vehicle-to-infrastructure channels along a test route in Bristol. Measured antenna patterns and an RF channel emulator are used to simulate the channels. Results from the VDT system show good alignment with measurements from physical drive tests and provide reliable and repeatable performance analysis without the costs of real-world testing.
