Tropospheric scintillation statistics in the millimetre-wave band have been obtained in Madrid, using the ITALSAT satellite beacon at 50 GHz. Few studies have been conducted previously at this band. The UCL radiosonde-based method predicts fairly well the mean variance and the distribution of amplitude in the summer months, when scintillations are stronger. The ITU-R prediction model, based on surface meteorological parameters, performs worse.

A one-year campaign of slant path attenuation measurements has been carried out in Madrid using the ITALSAT satellite beacon at 50 GHz. The experimental cumulative distributions of rainfall rate and rain attenuation are presented. The first one is compared with the ITU-R (International Telecommunication Union-Radiocommunication) maps while measured attenuation values are compared with several prediction models. Finally, the relationship between average year and worst month is investigated.Index Terms-Attenuation measurement, millimeter wave radio propagation, rain, satellite communication.

“…At that time the ITALSAT F1 satellite [8] was in service, providing two beacons at 40/50 GHz bands that could be used for taking propagation measurements in most countries of southern and central Europe [9]. An experimental receiver was built [6] in Madrid, capable of measuring the received level of the 49.49 GHz beacon. With the help of a radiometer and auxiliary meteorological equipment, the atmospheric attenuation could be derived from the measured signal level.…”

“…The use of FMT is considered as a way of improving the system availability. This particular system has been chosen for three reasons: The aforementioned allocation of the frequency band for this application, the existence of a proposed system [5], with publicly available detailed technical specifications, and the availability of experimental propagation data gathered in a previous research project [6] at that frequency band.…”

The 48 GHz band has been allocated world-wide for fixed service with HAPS. High-capacity broadband access networks can be implemented in this band. The main drawback is the troposphere effects on the propagation, particularly rain attenuation, that may limit the link availability. In this paper, the performance of HAPS-ground links working in this band is analysed by means of simulation. Experimental slant-path propagation data, gathered at 49.5 GHz, are used in the simulations, so that attenuation levels and their temporal evolution may be considered realistic. The simulated system is defined in ITU-R Rec. F-1500. Only urban coverage links are simulated, as the propagation data correspond to a 40°elevation link. The use of Fade Mitigation Techniques (FMT) is shown to be useful to improve the link performance. The improvement is evaluated for two different FMTs: Power control and adaptive coding. Results are presented regarding link availability and other parameters related to the particular FMT, as well as outage dynamics.
