Embodiments may receive signals using a receiver adapted for the wider bandwidth 802.11n/ac signals. Embodiments may also increase the sensitivity of the receiver to reduce the likelihood of missing the presence of a lower bandwidth 802.11p signal. When a signal is detected, embodiments may process the incoming signal as if it were an 802.11n/ac signal while also processing incoming signal samples in a way that effectively narrows the receiver bandwidth to identify whether an 802.11p signal is present. If the device detects the presence of an 802.11n/ac signal, it may terminate the 802.11p signal processing and proceed with normal 802.11n/ac operation. If the device detects the presence of an 802.11p signal, it may terminate 802.11n/ac processing and trigger collision avoidance processes."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detection of 802.11p signals in 802.11 n/ac enabled devices","description":"Embodiments allow a wireless device configured to work with the 802.11n/ac standard to work in the communication bands where 802.11p devices operate with little change.
