Systems and Methods for Secure Transaction Management and Electronic Rights Protection

What will 5G be? What it will not be is an incremental advance on 4G. The previous four generations of cellular technology have each been a major paradigm shift that has broken backward compatibility. Indeed, 5G will need to be a paradigm shift that includes very high carrier frequencies with massive bandwidths, extreme base station and device densities, and unprecedented numbers of antennas. However, unlike the previous four generations, it will also be highly integrative: tying any new 5G air interface and spectrum together with LTE and WiFi to provide universal high-rate coverage and a seamless user experience. To support this, the core network will also have to reach unprecedented levels of flexibility and intelligence, spectrum regulation will need to be rethought and improved, and energy and cost efficiencies will become even more critical considerations. This paper discusses all of these topics, identifying key challenges for future research and preliminary 5G standardization activities, while providing a comprehensive overview of the current literature, and in particular of the papers appearing in this special issue.

It is shown that, particularly for terrestrial cellular telephony, the interference-suppression feature of CDMA (code division multiple access) can result in a many-fold increase in capacity over analog and even over competing digital techniques. A single-cell system, such as a hubbed satellite network, is addressed, and the basic expression for capacity is developed. The corresponding expressions for a multiple-cell system are derived. and the distribution on the number of users supportable per cell is determined. It is concluded that properly augmented and power-controlled multiple-cell CDMA promises a quantum increase in current cellular capacity. >

On the capacity of a cellular CDMA system

The vision of next generation 5G wireless communications lies in providing very high data rates (typically of Gbps order), extremely low latency, manifold increase in base station capacity, and significant improvement in users’ perceived quality of service (QoS), compared to current 4G LTE networks. Ever increasing proliferation of smart devices, introduction of new emerging multimedia applications, together with an exponential rise in wireless data (multimedia) demand and usage is already creating a significant burden on existing cellular networks. 5G wireless systems, with improved data rates, capacity, latency, and QoS are expected to be the panacea of most of the current cellular networks’ problems. In this survey, we make an exhaustive review of wireless evolution toward 5G networks. We first discuss the new architectural changes associated with the radio access network (RAN) design, including air interfaces, smart antennas, cloud and heterogeneous RAN. Subsequently, we make an in-depth survey of underlying novel mm-wave physical layer technologies, encompassing new channel model estimation, directional antenna design, beamforming algorithms, and massive MIMO technologies. Next, the details of MAC layer protocols and multiplexing schemes needed to efficiently support this new physical layer are discussed. We also look into the killer applications, considered as the major driving force behind 5G. In order to understand the improved user experience, we provide highlights of new QoS, QoE, and SON features associated with the 5G evolution. For alleviating the increased network energy consumption and operating expenditure, we make a detail review on energy awareness and cost efficiency. As understanding the current status of 5G implementation is important for its eventual commercialization, we also discuss relevant field trials, drive tests, and simulation experiments. Finally, we point out major existing research issues and identify possible future research directions.

Next Generation 5G Wireless Networks: A Comprehensive Survey

Optimization of Packet Scheduling Schemes

This paper reports on satellite beacon measurements at 12.7 GHz from late October 2010 until the end of June 2012 at two geographically separated Arqiva Teleport sites in Southern England in order to obtain propagation data to be used in operational decision making and improvement of the scientific understanding of such effects. These sites operate at very low elevation angles 4.1 and 5.3 degrees and therefore experience significant propagation effects. Measurements are on-going to achieve meaningful long term statistics, however there is value in comparing the results obtained at both sites over the common period of measurement data to date approximately 20 months. The measurements are performed at 1/2 second intervals and statistical analysis applied. A primary objective of this work is to assess the influence of tropospheric scintillation and consequently the paper will focus on this with the addition of some lesser material on rain fade effects. The measurements and analysis have been performed as a collaborative effort between Arqiva and staff who work at the University of Surrey. It is emphasised that the primary objective of this work is to assess the influence of tropospheric scintillation and rain attenuation from an operational perspective and to a lesser extent from an academic viewpoint.

Automatic repeat request (ARQ), data carousels and packet-level forward error correction (PLFEC) are fundamental techniques for combating packet loss in point-to-multipoint communications. Generally speaking, ARQ-based techniques are unattractive due to the feedback implosion they generate. Furthermore, in broadcast/multicast wireless networks, radio resources are scarce and feedback may not be an option at all. Two error mitigation mechanisms that become relevant in this scenario are data carousels and PLFEC. In this work, we consider the application of these two techniques as components of an integrated layer in satellite environments. We also investigate the impact of the type of PLFEC code, small or large, on the main user-oriented performance metric of the data carousels, the average content download time

Integration of small and large packet-level FEC codes with data carousels for reliable multicast transport over satellite links

The potentialities of using EHF frequencies on a satellite for aeronautical broadband communication provision have been discussed in this chapter. Currently used Ka band frequencies will soon not be able to cope with the increased Internet demands from aircraft passengers. There do not appear to be any major regulatory barriers to adopting Q/V and W bands, except perhaps around airports. It has been shown that the propagation impairments in the troposphere that are preventing for now the use of those bands for satellite user links are not a major issue for aeronautical applications as the magnitude of those impairments is significantly decreasing with altitude. They are almost negligible at cruise level. The various tools available to size the propagation margins have been detailed. An outcome of the analysis is that the margins required to ensure more than 99.9% of availability could be lower than 10 dB for most of the flight configurations at Q/V and W band. In order to get an idea of the improvement of the performances brought by the use of those higher frequency bands, current aeronautical terminals and satellites characteristics' have been extrapolated to EHF. It has been shown that the capacities provided can be enhanced by use of conformal antennas and provide from 4 to 10 times increases over current Ka band systems. These would appear to accommodate the predicted requirements of around 200Mbps per aircraft made for 2020 and beyond. This demonstrates the feasibility of EHF satellite systems to meet future Aero passenger requirements, letting bandwidth for ground-based applications at lower frequency bands.

Propagation and system dimensions in extremely high frequency broadband aeronautical SatCom systems

Simultaneous frequency sharing in integrated satellite and terrestrial networks can help to achieve increased network capacity based on an efficient reuse of frequency resources in a way that minimizes interference. In this paper, we investigate the use of the 2GHz MSS frequency allocation for satellite and terrestrial mobile services based on LTE. Results show that uplink frequency sharing is not feasible due to the predominant terrestrial interference into the satellite service. On the other hand, downlink frequency sharing is feasible for pedestrian microcells and vehicular macrocells but not for the wider rural cells. In this regard, a satellite multimedia broadcast service can be deployed simultaneously with twoway terrestrial mobile service in urban and suburban areas. Furthermore, dynamic radio resource allocation combined with interference coordination can be used to optimize performance throughout the integrated network.
