  Extended Reality (XR) has stringent throughput and delay requirements that
are hard to meet with current wireless technologies. Missing these requirements
can lead to worsened picture quality, perceived lag between user input and
corresponding output, and even dizziness for the end user. In this paper, we
study the capability of upcoming Wi-Fi 7, and its novel support for Multi-Link
Operation (MLO), to cope with these tight requirements. Our study is based on
simulation results extracted from an MLO-compliant simulator that realistically
reproduces VR traffic. Results show that MLO can sustain VR applications. By
jointly using multiple links with independent channel access procedures, MLO
can reduce the overall delay, which is especially useful in the uplink, as it
has more stringent requirements than the downlink, and is instrumental in
delivering the expected performance. We show that using MLO can allow more
users per network than an equivalent number of links using SLO. We also show
that while maintaining the same overall bandwidth, a higher number of MLO links
with narrow channels leads to lower delays than a lower number of links with
wider channels.
