Performance of 5G Services Deployed via HAPS System

The 5G standard is a mobile communication of the 5
^th
generation, which promises to provide improved end-user experience by offering new applications and services through high data rates, and significantly enhanced performance and reliability. Operators may consider a portfolio of wireless technologies for 5G backhaul in addition to optical fiber, including point-to-multipoint (PMP), microwave and millimeter wave radio relays, high altitude platform station (HAPS) systems and satellites. This paper basically introduces an analysis of system performance to deliver 5G services over HAPS channel. The assessment is conducted for 5G-HAPS downlink system in different terms such as spectral efficiency and bit error rate. Results show that a poor performance occurs in low elevation angles of the ground user. It is also shown that a very promising method of delivering 5G services through HAPS system if user's elevation angle is maintained appropriately.
