  As the evolution of wireless communication progresses towards 6G networks,
extreme bandwidth communication (EBC) emerges as a key enabler to meet the
ambitious key performance indicator set for this next-generation technology. 6G
aims for peak data rates of 1 Tb/s, peak spectral efficiency of 60 b/s/Hz,
maximum bandwidth of 100 GHz, and mobility support up to 1000 km/h, while
maintaining a high level of security. The capability of 6G to manage enormous
data volumes introduces heightened security vulnerabilities, such as jamming
attacks, highlighting the critical need for in-depth research into jamming in
EBC. Understanding these attacks is vital for developing robust
countermeasures, ensuring 6G networks can maintain their integrity and
reliability amidst these advanced threats. Recognizing the paramount importance
of security in 6G applications, this survey paper explores prevalent jamming
attacks and the corresponding countermeasures in EBC technologies such as
millimeter wave, terahertz, free-space optical, and visible light
communications. By comprehensively reviewing the literature on jamming in EBC,
this survey paper aims to provide a valuable resource for researchers,
engineers, and policymakers involved in the development and deployment of 6G
networks. Understanding the nuances of jamming in different EBC technologies is
essential for devising robust security mechanisms and ensuring the success of
6G communication systems in the face of emerging threats.
