Simultaneous dual band operation (2.4 and 5 GHz) is common in APs on the market today, and tri-band devices are expected in the market soon. Link aggregation can also be applicable to multiple air interfaces in the same band (for instance 2 independent IEEE 802.11ac/ax air interfaces at 5 GHz on 2 different 80 MHz channels). One exemplary aspect provides technology that enables significantly higher throughput and/or higher reliability for two stations (STAs) or a STA and the access point (AP) when the devices support simultaneous multi-band operation.
