Traditional wireless LAN analysis relied on USB adapters being used as receivers to capture wireless packets for analysis. With 11ac, these days are long gone. USB is just not capable of moving data at the rates possible with 11ac. A new method for capturing data for analysis is required.
In order to effectively and efficiently capture and analyze 802.11ac traffic for analysis, WildPackets recommends using access points (APs). Using APs as packet capture devices is hugely beneficial because the APs are already part of the network and are typically specified to handle the most capable clients that will connect to your WLAN – guaranteeing that you’ll have the capacity to capture whatever traffic is on your WLAN.
Analysis can be performed by either connecting an AP directly to a laptop running OmniPeek via the Ethernet port, or by collecting data remotely from APs that are deployed as part of the WLAN. For either approach, OmniPeek supports two different, but similar, connection methods. The first is using remote PCAP (RPCAP) and the second is using custom remote adapters.
