What is jamming? The theoretical principle behind it is the jamming of data transmission in general between a transmitter and a receiver. The practical principle defines however the exclusive jamming of the data receiver. At this point of transmission the signal is weakest and most open to attack. There are few ways to attack the data exchange between two wireless connected points. This paper gives an insight into communications jamming from the topic area of information security.

Chapter Summaries
1 INTRODUCTION: This introductory chapter establishes the scope and purpose of the paper, defining jamming as the intentional disruption of data reception in wireless communications, differentiating it from passive listening or higher-layer attacks. It highlights the dual civilian and military applications of jamming, setting the stage for a deeper exploration of communications jamming specifically. The chapter emphasizes the importance of timely information and how jamming, while not completely blocking communication, significantly impacts its timeliness.
2 JAMMING – ELECTRONIC WARFARE: This chapter traces the historical development of jamming, originating in military strategies to disrupt enemy radio communications. Examples from World War II and the Cold War illustrate its use in preventing enemy interception and control of information flow. The chapter also mentions the continuing relevance of satellite jamming as a political tool in certain regions.
2.1 DEFINITION OF JAMMING DURING THE COLD WAR ERA: This section further elaborates on the definition of jamming during the Cold War, differentiating between ground-wave (local) jammers and sky-wave (long-range) jammers. It details the technological aspects of each type, contrasting the low-powered, short-range local jammers with the high-powered, long-range jammers used for broader coverage.
3 JAMMING – WIRELESS NETWORK: This chapter shifts the focus to jamming in the context of wireless networks, defining it as the disruption of wireless transmissions by reducing the signal-to-noise ratio at the receiver. It introduces various types of jammers, including proactive, reactive, function-specific, and smart-hybrid jammers, emphasizing that the effectiveness of jamming depends on factors like power, location, and impact on the network. The chapter briefly touches on the concept of signal-to-noise ratio (SNR) to provide a basis for understanding the effectiveness of jamming attacks.
