Abstract

In this paper, we present the Very High Throughput (VHT) introduced for the first time by the standard IEEE 802.11ac. We show that we can find an optimized set of parameters which leads to the best performance. We analyze the performance of the standard, while taking into account several features of the PHY and the MAC layers in a MIMO channel, and we compute the throughput using an analytical model verified by simulation of the performance of different aggregation schemes, different modulation and coding schemes and various channel widths. We prove that a carefully chosen set of parameters can increase the throughput remarkably with the hybrid aggregation scheme A-MPDU of A-MSDU providing the best results for the chosen scenario.
