“…Moreover, routing at network layer and allocation of resources at link layer have to be performed in a joint way for the different segments to satisfy traffic requests and minimizing at the same time the cost of the allocated bandwidth among the heterogeneous network components [49]. More advanced form of cooperative diversity and relay techniques will be developed not only to enhance the performance but also to increase spectral efficiency.…”

SUMMARYFuture mobile networks are expected to involve systems that are based on different technologies, such as WiFi, WiMAX, 2G/3G/3G1, LTE, and satellite. To address this scenario, ITU has defined integrated and hybrid networks in the framework of Next-Generation Networks. The interest is to exploit the cooperation of different wireless communication systems (segments) to provide service to mobile users in the most efficient way, taking into account signal quality (coverage), traffic congestion conditions, and cost issues. Integrated and hybrid networks have the potential to be an efficient and cost-effective solution to employ satellite communications for mobile users. In the view of this, our paper focuses on the design of integrated/hybrid systems taking into account physical, MAC, and network layers issues. System examples and standards are described as well. Then, cooperative diversity techniques and traffic engineering issues for overflow traffic are discussed. This paper concludes identifying some possible future trends.

“…Standard terminals can be boosted with external power amplifier and antenna module. Because of the emerging importance of these kinds of networks, there have been various studies on these [14][15][16]. For example, reference [14] addresses the role of satellite communications in future telecommunication networks and service provision considering integration of satellite and terrestrial system in future multimedia communications, and discusses the research challenges and technology advancement required to facilitate this integrated approach.…”

SUMMARYThis paper provides an overview of a technical study on the satellite radio interfaces based on 3GPP WCDMA system. First, the outcome of the technical study is introduced, which has been carried out by the Mobile Satellite System Working Group of the ETSI Satellite Earth Satellite Technical Committee (ETSI TC SES MSS). The study dealt with the configurations and performance of the 3GPP WCDMA (UTRAN) radio interface over a satellite link. Second, as an evolution of satellite-specific radio interface, the study results are addressed on the possible adaptations of WCDMA to the satellite link in order to maximize the radio link performance. The resultant outcome of the study was reflected in a detail on the G and C families of the satellite radio interface of the ITU-R Recommendation M.1457, respectively.

The Fourth Generation (4G) of wireless communications systems is coming, combining voice and data on a single packet-based all-IP core network, with bandwidth providing data rates in the range of a few to hundreds of MB/s. This new high-speed data network, combined with the latest technology developments, should enable the advent of a multitude of new multimedia applications, which will be available to the user on his own handset. Following the wireless Personal Communications Systems (PCS) trend, Satellite Personal Communications Systems (SPCS) are also expected to provide multimedia applications on this integrated network. However, as this new technology is rolled-out, it is also expected that it will come with its own set of vulnerabilities that could potentially constitute a threat to network reliability and secure communications. Because of its numerous advantages, SPCS is known to be used for security and defence applications by military and paramilitary forces around the world. From a defence perspective, it is therefore imperative to address this potential emerging threat.
