real simultaneous dual band (WiFi) (RSDB)

Real Simultaneous Dual Band (RSDB) is a real, simultaneously usable dual-band technology that can be implemented in WiFi. With this technology, an end device can communicate simultaneously in the 2.4 GHz band and in the 5 GHz band.

In Real Simultaneous Dual Band (RSDB), the channel bandwidths are 20 MHz at 2.4 GHz and 80 MHz at 5 GHz, and can increase throughput accordingly in RSDB operation.

Devices with RSDB implementations have a dual design in terms of radio technology and in the MAC layer, namely for 2.4 GHz and 5 GHz. With this technology, the 2.4 GHz band can be used to connect smartphones, tablets or notebooks, while at the same time TCP data can be transmitted at 300 Mbit/s in the 5 GHz band. In motor vehicles, this technology could be used to transmit streaming video to displays in front of the rear seats.
