Devices, computer-program products, and methods for identifying two or more traffic flows with similar packet traffic characteristics are disclosed. In some implementations, the traffic flows may be transmittable over one or more wireless paths. In these implementations, the method may further include identifying a wireless path along which the two or more traffic flows may be transmitted. In some implementations, the method may further include determining whether the wireless path can implement spatial signal multiplexing. Making this determination may include using sounding information associated with the wireless path. In some implementations, the method may include grouping two or more traffic flows to transmit along the wireless path when the wireless path implements spatial signal multiplexing. In these implementations, the two or more traffic flows may be grouped according to similar packet traffic characteristics. Grouping the two or more traffic flows may allow spatial signal multiplexing on the wireless path.
