Millimeter-wave wireless backhauling for 5G small cells: Star versus mesh topologies

MmWave wireless communication, operating in the 10–300 GHz band, appears to be a promising candidate for the next generation of cellular systems by which multiple gigabit-per-second data rates can be supported. It is a promising technology for future cellular systems, especially in mobile backhauling for the new small-cell evolution. In this paper, MmWave backhauling is considered in two different topologies; a star topology and a mesh topology. The two topologies are compared from the point of view of the system throughput. Different scenarios are considered including the Line Of Sight (LOS) and the Non Line Of Sight (NLOS) connections.
