Wi-Fi
What distinguishes the new Wi-Fi 6 standard
from its predecessor, Wi-Fi 5?
Wi-Fi 6 (IEEE 802.11ax) is the next stage in the
evolution of the Wi-Fi standard. The evolved
standard expands upon the advantages of its
predecessor while offering
functionality. It features higher efficiency, greater
flexibility and better scalability on the 2.4 GHz and
5 GHz frequency ranges.
Highlights of the WiFi 6 Repeater 5400 include
higher Wi-Fi speeds of up to 5400 Mbps and more
efficient data transfer. This goal was reached by
optimising the Wi-Fi protocol. One of the
improvements is the individual control of the data
rate depending on the reachability of the Wi-Fi
clients. This optimisation boosts the efficiency of
the protocol when there are multiple devices
retrieving data simultaneously. This is why the Wi-
Fi 6 standard is also referred to as "high-efficiency
Wi-Fi": the objective is to increase throughput per
unit of surface area.
Another technology that is used to achieve this
efficiency boost is
Frequency-Division Multiple Access). This method
