Spectrum

Abstract

Abstract � HAPS is a new technology in the wireless communications field. The straightforwardness with which HAPS gets along with service providers will make this system a unique feature of future wireless networks. Most of the HAPS criteria have been well documented by the International Telecommunication Union (ITU) or subscribed to in World Radio Conferences (WRCs) periodicals. This procedure will prolong to function for various frequency ranges in future, most notably in WRC-12. Here, the emphasis is on HAPS spectrum sharing with FSS in the Frequency range 5850-7075 MHz. To clarify, FSS links are planted in the C-Band frequency range for tropical and subtropical regions, with high amounts of rain, which serve to condense the propagation attenuation. Furthermore, FSS uplink frequency ranges between 5925 and 6725 MHz. Therefore, FSS uplink intervenes with HAPS frequency range causing interference. This paper will assess and clarify the prospects of implementing HAPS gateway links in co- and adjacent channels of FSS uplink regarding MD and NFD techniques. 1
