To support the increasing need for WiFi gigabit links, the IEEE 802.11ac technology introduced 80MHz and 160MHz channels, which led to an extended WiFi channelization at 5GHz, spanning over the ISM band up to 5.9GHz. However, 5.9GHz also accommodates the 70MHz spectrum reserved for vehicular traffic safety-related applications using IEEE 802.11p technology, forcing both technologies to coexist. In this paper, we highlight the inherent differences between these two technologies and formulate the coexistence challenge on a basic urban scenario. We present and evaluate two coexistence protocols proposed by the WiFi community. Lastly, we illustrate WiFi potential 'harmful' interferences to safety-related ITS applications and propose improvements for a better coexistence.
