This work presents a characterization of the radio channel of the next evolution of Wi-Fi standard IEEE802.11ac with a bandwidth of 80MHz around the frequency range of 5 GHz for three different indoor environments: a lecture hall, corridor and banquet hall. These environments are selected to represent three different levels of dispersion in the delay and direction domains. The very wide bandwidth results in high resolution in the delay domain and leads to splitting delay clusters as the distance between transmitter and receiver increases. The radio channel of this system is expected to have a variable number of delay clusters with different excess delays per cluster. The spread and geometric distance distribution of scatterers are the main factors that determine the cluster characteristics of this radio channel.
