LTE MAC Lab is a system-level simulation tool running under Matlab. LTE MAC Lab allows customers to model a wireless LTE network deployment, analyse its performance and understand dynamic mechanisms of the radio interface. It reflects the dynamic behaviour of a modelled HetNet RAN (Figure 1) focusing on Radio Resource Management features such as scheduling, carrier aggregation, handovers and link adaptation. It includes implementation of propagation (path loss, shadowing and multipath) and mobility models.

In LTE MAC Lab a user models wireless network behaviour operating under controlled parameters and various radio resource management schemes (Figure 2). The tool allows simulating networks with any number of base stations and with a maximum number of 5 aggregated component carriers (which gives the maximum bandwidth of up to 100 MHz). After running the simulations, transmission statistics and performance parameters are determined including system and user throughput, received power distribution, SNIR map and many more.

LTE MAC Lab is implemented as a library of modular functions with well-defined interfaces, which allows a user to include its own algorithms. The tool has a 1 ms time stamp for accuracy, which can be traded for speed.
