The aim of this paper is to demonstrate, how to communicate the vehicle between themselves in a heterogeneous vehicles network, and show on which way is done the exchange of information with the infrastructure, to overcome the shortcomings of using a single wireless technology. DSRC does not offer enough good coverage and range around intersections in urban areas for specific applications. On the other side, as an alternative to overcoming these deficiencies proposed LTE, advanced mobile communications technology. The evaluation of performance is usually done by means of simulations in particular the programming software, which integrates tools to support Wi-Fi, IEEE 802.11p, mobile technology and feedback mobility. For the realization of heterogeneous networks vehicle that has support for LTE is used open source simulator for communication between vehicles and infrastructure Veins LTE, composed of a network simulator Omnet++ and traffic simulator SUMO. These two simulators are working in parallel, and allow modeling of communication between vehicles.

Introduction of LTE-Advanced network brings a series of new techniques as well as an improvement of the existing ones, which contributes to better performance in relation to LTE network. Enhanced MIMO represents one of LTE-Advanced network’s most significant techniques which enable considerably better performance. Spectral efficiency and throughput are important system performance indicators. The paper aims to estimate LTE-Advanced network performance by applying an enhanced MIMO. The results verify consistency with given the analytical values, as well as which system parameter has the greatest influence on the achieved results. When enhanced MIMO is applied, several performance testing scenarios have been created depending on the parameter which was analysed for the given scenario, namely: LTE-Advanced channel scenario, antenna configuration, number of HARQ retransmissions and the type of subframe mode.
