Performance Analysis of Wireless Mesh Backhauling Using Intelligent Reflecting Surface
This paper considers the deployment of intelligent reflecting surfaces (IRSs) technology for
wireless multi-hop backhauling of multiple basestations (BSs) connected in a mesh topology. The
performance of the proposed architecture is evaluated in terms of outage and symbol error
probability in Rician fading channels, where closed-form expressions are derived and demonstrated
to be accurate for several cases of interest. The analytical results corroborated by simulation, show
that the IRS-mesh backhauling architecture has several desired features that can be exploited to
overcome some of the backhauling challenges, particularly the severe attenuation at high frequencies.
