Speed advantage through crossband repeating: The parallel use of the 2.4 and 5 GHz Wi-Fi frequencies increases the transmission rates in the Wi-Fi network, since sending and receiving can take place in parallel.
Repeaters that can only use the 2.4 GHz frequency, initially receive data packets from the router and then forward them to the Wi-Fi client on the same frequency. Although this results in a large range, it also leads to drops in speed. Crossband repeating avoids these speed losses.
If a repeater makes use of crossband repeating, it is capable of significantly more efficient data utilization. If data changes flexibly from the 2.4 to the 5 GHz band at the repeater's node, there is no loss of speed.
That's because the repeater can send and receive data simultaneously and independently. This enormously increases the data speed within the home network.
