“…Demands on increased traffic driven by higher internet rates and video are forcing the use of even higher bands e.g. Q/V and their characterization [51] or even W band [52]. The use of smart gateway schemes which switch traffic around a network of gateways may also prove necessary to achieve availabilities in the Ka/Q/V bands [53] and possibly the future use of optical satellite links and optical technology on board satellites [54] [55].…”

“…For this reason, the push towards higher frequencies will characterize future R&D on satellite communications [2]. Recently, some proposals for the exploitation of Q/V-bands (31-60 GHz) and Wband (75-110 GHz) in satellite communications are being issued [3]. W-band seems to provide a favorable "attenuation window" related to Oxygen absorption (values around 0.05 dB/km [4]).…”

“…W-band seems to provide a favorable "attenuation window" related to Oxygen absorption (values around 0.05 dB/km [4]). In addition, W-band is still scarcely used for data transmission (only analog radar applications are supported in those frequencies [3]) and, therefore, interference level is very low. For these reasons, despite the increasing attenuation due to rain, water vapor and clouds, W-band is regarded as a good candidate for supporting future broadband services in the millimeter wave domain.…”

In the EHF (Extremely High Frequency) domain, W-band (75-110 GHz) offers promising perspectives for future satellite communications, mainly in terms of large bandwidth availability for high-bit-rate transmission. In this work 1 , an innovative physical (PHY) layer design for broadband satellite connections operating in W-band is proposed, which is based on the Prolate Spheroidal Wave Functions (PSWFs). PSWF waveforms (originally proposed in short-range indoor Ultra Wideband (UWB) communications) are aimed at optimizing the tradeoff between the concentration of pulse energy in a finite time interval and in a limited bandwidth. In our paper, PSWF-based 4-ary PSM modulation, characterized by a nearoptimal compromise between spectral and envelope compactness, has been tested for the radio interface of a W-band geostationary (GEO) downlink connection. The effect of nonlinear distortions, introduced by power-efficient saturating amplifiers, can be drastically reduced without any power back-off and maintaining a very good spectral efficiency. Experimental results, obtained by means of realistic simulations, fully demonstrate the potential advantages taken by PSWF in terms of increased spectral efficiency, link availability and net payload rate with respect to state-of-the-art pulse-shaped modulations (raised-cosine filtered QAM and Gaussian Minimum Shift Keying), commonly employed in satellite communications.

“…In this frame, a series of research programs cofunded by the Italian Space Agency (ASI) have aimed, starting from 1998, at pioneering the W-band frequency range (75-110 GHz) for broadband satellite communications and integrating the W-band satellite system with the Internet [5][6][7][8]. The activities have been and are being undertaken by a large team of aerospace industries and scientific institutions.…”

The paper addresses advanced layered architectures for the development of integration scenarios between satellite navigation and communications systems and services. This synercic cooperation represents -in author's vision -the core of future global networks. The concept of integration and its translation into an integrated network is displayed, together with examples of possible architectures for navigation-communications applications. In this frame, the paper addresses also the possible exploitation of stratospheric platforms (HAP) as permanent and on-demand blocks concurring to the effective deployment of the integrated vision.
