28 Next-Gen Connectivity for Smart Living
Multi-Link Operation
MLO technology enables Wi-Fi devices to use multiple
channels across different frequency bands simultaneously
for transmission and reception over multiple links. This
technology enhances speed in congested environments and
promises a much more robust wireless link. MLO also has
the potential to dramatically reduce latencies by making
use of frequency bands that are more responsive in a
given environment.
High Band Simultaneous Multi-Link
High Band Simultaneous (HBS) Multi-Link is a feature that
allows the simultaneous use of two Wi-Fi radios for four-
stream operation in the high-frequency bands of 5GHz and
6GHz. This is especially promising for areas where the 6GHz
spectrum is not yet available, as HBS Multi-Link allows
for the aggregation of two 160MHz channels in the 5GHz
band for a link that can deliver 5Gbps or a combination of a
160MHz and 80MHz channels that can still provide speeds 50
percent faster than Wi-Fi 6/6E.
Enhanced Multi-link Single Radio
Enhanced multi-link single radio (EMLSR) technology is
designed to enable efficient dynamic switching among
multiple Wi-Fi bands. With EMLSR, a client can listen on two
channels, but transmission only occurs on a single channel.
To achieve this, the client device performs Clear Channel
Assessment (CCA) and receives a control frame, which allows
the client to indicate where the next transmission will occur.
