چکیده
This Recommendation provides methodologies for the interference evaluation from the HAPS-to-ground transmission downlink of the fixed service (FS) using high altitude platform stations to the uplink of the fixed-satellite service using the geostationary satellites within the bands 27.5-28.35 GHz.This Recommendation contains three Annexes that provide methodologies for interference calculation, calculation of the e.i.r.p. of transmission from HAPS, interference evaluation in terms of C/I and examples of applications of the methodologies in the Appendix.

Spectrum planning and performance evaluation between heterogeneous satellite networks
A new network has been recently proposed for the provision of fixed broadband services via high altitude platform stations (HAPS) in the 48/47 GHz band. One of the critical issues of this technology is spectrum sharing with the fixed satellite service. This paper examines the effect of Earth-to-stratosphere co-channel interference produced by ground stations of HAPS network to geostationary orb...
متن کاملCellular Networks, Satellite Communication 1 Satellite Communication
A satellite communications system is based on antennas in a stable orbit above the earth. Satellites serve as relay stations in the sky. The basic idea of satellite communications is that two stations on earth discuss via one or more satellites. So a little bit of satellite-related terminology: 1. Earth station is an antenna on or near the surface of the earth. 2. Uplink is a transmission from ...
متن کاملRECOMMENDATION ITU-R SF.1649-1 Guidance for determination of interference from earth stations on board vessels to stations in the fixed service when the earth station on board vessels is within the minimum distance*
Scope This Recommendation provides guidance to administrations for the determination of the interference potential of earth stations on board vessels (ESVs) to stations in the fixed service. Annex 1 provides general considerations for this determination. Annex 2 provides a description of the most basic approach to such a determination. Annex 3 provides several alternative approaches based on si...
متن کاملResource Allocation for Cognitive Satellite Uplink and Fixed-Service Terrestrial Coexistence in Ka-Band
This paper addresses the cognitive Geostationary Orbit (GSO) satellite uplink where satellite terminals reuse frequency bands of FixedService (FS) terrestrial microwave links which are the incumbent users in the Ka 27.5-29.5 GHz band. In the scenario considered herein, the transmitted power of the cognitive satellite user has to ensure that the interference impact on potentially present FS link...
متن کاملExtending the Spectrum for Ka-band Satellite Systems by Use of the Shared Bands
The spectrum available in the exclusive Ka-bands has been shown to be insufficient to meet the demands of broadband access by satellite post 2020. This paper presents the work of the FP7 project CoRaSat in validating the use of the extra spectrum in the shared Ka bands for use by satellite. It is demonstrated that in the 17.3 to 17.7GHz band shared with Broadcasting Satellite Service (BSS) feed...
