For example, a wireless communication multi-stream sniffer may configure a plurality of wireless communication sniffers to sniff a respective plurality of wireless streams by configuring the plurality of wireless communication sniffers according to a respective plurality of stream configurations; process a plurality of sniffer streams from the plurality of wireless communication sniffers, a sniffer stream from a wireless communication sniffer of the plurality of wireless communication sniffers including frame information of frames captured by the wireless communication sniffer according to a stream configuration of the wireless communication sniffer; and generate a unified sniffer stream by combining the plurality of sniffer streams based on the plurality of stream configurations.
