The development of computing technologies has made it possible not only to expand the range of mobile communication services, but also to significantly increase computing capabilities. The emergence of mobile Internet, 4G, 5G technologies makes it possible to talk about a fundamentally different approach to ensuring the quality of service to network customers, creating fundamentally new approaches to ensuring the efficiency and reliability of transmitted information flows. However, such a rapid growth of GSM technologies without the introduction of security services leads to active actions of attackers and cyber terrorists, the emergence of new and modification of known threats. Mobile communication channels are used by cybercriminals for selfish purposes of access to database resources not only of the mobile Internet, but also to the databases of information and communication systems and networks. The article proposes a fundamentally new approach to ensuring the closure of the voice channel of the mobile Internet based on post-quantum cryptography algorithms – McEliece and Niederreiter crypto-code constructions on elliptic codes. This approach provides not only the offline mode of closing the voice channel and creating a VPN channel in tunnel mode, but also the required level of cryptographic strength in the face of the emergence of full-scale quantum computers.

With the rapid development of mobile internet, more and more frequency band will be needed to meet the requirement of high data speed. The system coexistence between mobile system and broadcast system is studied, including the scenarios, models, simulation results, related analysis, and finally the solution to resolve the coexistence is given. In urban, an additional 37dB isolation between broadcast system and mobile base station should been satisfied. And an additional 15.7dB is needed between mobile base station and broadcast receiver.

AbstractIt is suggested that the development of the SKA will drastically change the face of radio astronomy in the 21 st Century. A FAST-style SKA would admit observations of low contrast features, and would be the best design for studying the ‘dark ages’ of the Universe (x » 1) where sub-arcmin total power instruments can usefully be employed. To date there have been no proposals for post-SKA, billion square-metra instruments; we speculate that mobile communication systems can be used. In the very distant future, SKA multi-beam systems could be used to collect signals reflected by Solar system bodies such as the asteroid belt.

IntroductionCommunication today is increasingly seen as a process through whichthe exchange and sharing of meaning is made possible. Commtinication asa subject of scientific inquiry is not unique to the field of mass communication.Mathematicians, engineers, sociologists, psychologists, political scientists,anthropologists, and speech communicators have been taking an interest inthe study of communication. This is not surprising because communicationis the basic social process of human beings. Although communication hasgrown into a well developed field of study, Muslim scholars have rdrely hcusedon the study of communication. Thus, a brief introduction to the widely usedcommunication concepts and a framework for the study of communicationwithin the context of this paper is provided.In 1909, Charles Cooley defined communication from a sociologicalperspective as:The mechanism through which human relations exist and develop -all the symbols of mind, together with the means of conveyingthem through space and preserving them in time. It includes theexpression of the face, attitude and gesture, the tones of the voice,words, writing, printing, railways, telegraph, and whatever elsemay be the latest achievement in the conquest of space and time.In 1949, two engineers, Claude Shannon and Warren Weaver, definedcommunication in a broader sense to include all procedures:By which one mind may affect another. This, of course, involvesnot only written and oral speeches, but also music, the pictorialarts, the theater, the ballet, and, in kct, all human behavior.Harold Lasswell, a political scientist, defines communication simply as:A convenient way to describe the act of communication is to answerthe following question: Who, says what, in which channel, towhom, with what effect?S.S. Stevens, a behavioral psychologist, defines the act of communication as:Communication occurs when some environmental disturbance (thestimulus) impinges on an organism and the organism doessomething about it (makes a discriminatory response) . . . Themessage that gets no response is not a commnication.Social psychologist Theodore Newcomb assumes that:In any communication situation, at least two persons will becommunicating about a common object or topic. A major functionof communication is to enable them to maintain simultaneousorientation toward one another and toward the common object ofcommunication.Wilbur Schramm, a pioneer in American mass communication research,provides this definition:When we communicate we are trying to share information, anidea, or an attitude. Communication always requires threeelements-the source, the message, and the destination (thereceiver).

Over the past decades, waves of political contention involving the use of information and communication technologies have swept across the globe. The phenomenon stimulates the scholarship on digital communication technologies and contentious collective action to thrive as an exciting, relevant, but highly fragmentary and contested field with disciplinary boundaries. To advance the interdisciplinary understanding, Shifting Dynamics of Contention in the Digital Age outlines a communication-centered framework that articulates the intricate relationship between technology, communication, and contention. It further prods us to engage more critically with existing theories from communication, sociology, and political science on digital technologies and political movements. Given the theoretical endeavor, Shifting Dynamics of Contention in the Digital Age systematically explores, for the first time, the influence of mobile technology on political contention in China, the country with the world’s largest number of mobile and Internet users. Using first-hand in-depth interview and fieldwork data, it tracks the strategic choice of mobile phones as repertoires of contention, illustrates the effective mobilization of mobile communication on the basis of its strong and reciprocal social ties, and identifies the communicative practice of forwarding officially alleged “rumors” as a form of everyday resistance. Through this ground-breaking study, Shifting Dynamics of Contention in the Digital Age presents a nuanced portrayal of an emerging dynamics of contention—both its strengths and limitations—through the embedding of mobile communication into Chinese society and politics.
