The telecommunication industry has recently seen two areas with very high growth rates: cellular networks, for example, GSM (Global System for Mobile Communications) or UMTS (Universal Mobile Telecommunications System), and P2P (Peer-to-Peer) file-sharing applications. A combination of both might be highly attractive: a) for attracting new users; and b) for exploiting the potential of cellular broadband technologies. From a system’s perspective, architectures and performance figures of cellular mobile network applications and services that have edge-based intelligence (e.g,. P2P applications) are, to the best of the authors’ knowledge, less researched and many questions remain open. This chapter presents the design of MP2P (Mobile P2P) applications for cellular mobile networks by using the example of a MP2P content-distribution application. First, the incompatibilities between the P2P paradigm and properties of cellular mobile networks are identified. Then, a design methodology for MP2P applications for cellular mobile networks is proposed. The proposed method is based on a functional analysis of the two basic P2P functions, resource mediation and resource access control. The result is a hybrid P2P content-distribution architecture, which is enhanced by different operator-controlled infrastructure elements. The suggested architecture does not only overcome incompatibilities between P2P and cellular mobile communication systems, it also meets the functional needs and performance requirements of future P2P applications in cellular environments, while still largely preserves the user characteristics and efficiency of P2P systems. Finally, the performance enhancements by the architecture for the two basic P2P functions are investigated by comprehensive simulative and analytical performance evaluations.

In this work we aim to provide a comprehensive summary of the most inspiring aspects of 5G mobile networks. In addition, we present the latest findings on the promising 6G technology towards a world of fully digital connectivity. The key determinants are extreme system performance and combinations of requirements for new use cases. We study new performance targets beyond 5G in two stages: 5G+ evolution and new 6G step. Relevant technologies considered too immature for 5G or outside the defined scope are outlined. To justify our vision of future mobile networks, we point out the need for closer collaborations of academia, standardizing bodies, industrial organizations and governments. The contribution strategy is gradual evolution and performance enhancement of mobile communications. Finally, we identify challenges and directions on network technology roadmap toward 6G. Keywords: wireless communication, mobile broadband, low-latency communi-cation, 5G network, 3GPP, 6G vision

The performance of P2P content distribution in cellular networks depends highly on the cooperation and coordination of heterogeneous and often selfish mobile users. The major challenges are the identification of problems arising specifically in cellular mobile networks and the development of new cooperation strategies to overcome these problems. In the coherent previous chapter, the authors focused on the selfishness of users in such heterogeneous environments. This discussion is now extended by emphasizing the impact of mobility and vertical handover between different wireless access technologies. An abstract mobility model is required to allow the performance evaluation in feasible computational time. As a result, the performance in today’s and future cellular networks is predicted and new approaches to master heterogeneity in cellular networks are derived.

Motivated by the requirements for higher data rate, richer multimedia services, and broader radio range wireless mobile networks are currently in the stage evolving from the second-generation (2G), for example, global system for mobile communications (GSM), into the era of third-generation (3G) or beyond 3G or fourth-generation (4G). Universal mobile telecommunications system (UMTS) is the natural successor of the current popular GSM (http://www.3gpp.org) code division multiple access 2000 (CDMA2000) is the next generation version for the CDMA-95, which is predominantly deployed in North America and North Korea. Time division-sychrononous CDMA (TD-SCDMA) is in the framework of 3rd generation partnership project 2 (3GPP2) and is expected to be one of the principle wireless technologies employed in China in the future (http://www.3gpp.org; 3G TS 35.206). It is envisioned that each of three standards in the framework of international mobile telecommunications- 2000 (IMT-2000) will play a significant role in the future due to the backward compatibility, investment, maintenance cost, and even politics.

The tremendous use of telecommunication services and the existence of various types of mobile devices and networks impose a huge need for a new technology that can integrate these devices and networks to provide adequate services and applications to satisfy the user’s needs. The new technology tries to eliminate all boundaries of telecommunications and leads to a universal approach that is able to demonstrate an easy and efficient technique to overcome all technical and managerial issues. This chapter, first, studies and analyzes the performance of existing mobile systems and their services and estimates the future aspects of next generation mobile communications. Second, a new approach is proposed and investigated. The new approach is based on using the abilities of satellite communications as part of the mobile communication systems. Such an approach introduces advanced communication solutions that could be set up anywhere/anytime subject to the existence of satellite coverage.

This paper presents novel mobile phone antenna for radiations simultaneously in ten frequency bands for applications of LTE (Long-Term Evolution), GPS (Global Positioning System), GSM (Global System for Mobile Communications), PCS (Public and Commercial Services), DCS (Distributed Control System), UMTS (Universal Mobile Telecommunications System) and WiMAX (Worldwide Interoperability for Microwave Access). The antenna demonstrates novel characteristics for resolving the challenge of simultaneous radiation capabilities for the GSM and GPS applications with frequencies of 850/900 and 1575 MHz respectively, along with resonances at frequency band of 700 MHz for LTE applications, 1800 and 1900 MHz for PCS and DCS applications, 2100 MHz for UMTS applications, 2400 and 2500 MHz for LTE applications and 3300 MHz for WiMAX applications with S11 = - 6 dB matching criteria (VSWR 3:1). The antenna architecture comprises top and bottom copper layers embedded with monopole radiating element, branch line, slots and various stub lines. The desired operating bands are achieved in a compact area with overall dimensions of 0.8x60x120 mm for the height, width and length respectively of the antenna providing suitable platform for mobile handset applications. Omni-directional radiation pattern characteristics are achieved throughout the range of frequencies by designing the proposed antenna in monopole configuration. Proposed antenna is fabricated and results for the surface currents, s-parameters and 3D (Three-Dimensional) gain plots are illustrated for the proof of concept.
