After more than a decade of existence, the Conference on Electronics, Communications and Networks (CECNet) series has become established as a mature event. CECNet is held annually, and covers many interrelated groups of topics such as electronics technology, communication engineering and technology, wireless communications engineering and technology and computer engineering and technology.

Electronics, communication and networks coexist, and it is not possible to conceive of the current society without them. The next decade will probably see the consolidation of 6G-based technology, accompanied by many compatible devices. On a different topic, data centers are on the rise, and fiber-optic is now the most advanced technology, with many applications such as fiber to the home, fiber to the desktop, fiber for business and fiber to the node. As regards speed, we may soon have 100 Gb/s passive optical networks operating at a symmetrical mode. Going beyond this, 400 Gb/s may be achieved for long hauls with compact optical transceivers, and rates of 800 Gb/s for short hauls are possible. The trend is to have a hybrid coax-fiber material to take advantage of both technologies. TDSL (Terabit DSL) is not a new concept, and performance of about 2 Tb/s at a distance of 200 meters is also possible. Circular data centers are the future trend, with the idea that the heat generated by a data center could be used in, for example, a greenhouse.

This book contains the papers accepted and presented at the 12th International Conference on Electronics, Communications and Networks (CECNet 2022), held from 4–7 November 2022 as a virtual event with no face-to-face participation in Xiamen, China. All papers were carefully reviewed by program committee members, who took into consideration the breadth and depth of the research topic that fall within the scope of CECNet. CECNet 2022 was also a reference conference, and attracted many remarkable keynote speakers, such as Prof. Lyudmila Mihaylova, Department of Automatic Control and Systems Engineering, University of Sheffield, United Kingdom; Prof. Xiangjie Kong, College of Computer Science & Technology, Zhejiang University of Technology, China; and Prof. Victor Chang, Aston Business School, Aston University, United Kingdom.

CECNet 2022 received 313 submissions, and after a lively discussion stage, the committee decided to accept 79 papers, which represents an acceptance rate of about 25%.

I would like to thank all the keynote speakers and authors for their efforts in preparing a contribution for this leading international conference. Moreover, I am very grateful to all those, especially the program committee members and reviewers, who devoted their time to evaluate the papers. It is a great honour to continue with the publication of these proceedings in the prestigious series Frontiers in Artificial Intelligence and Applications (FAIA) from IOS Press.

Finally, although I hope you enjoy your virtual visit to Xiamen, I also hope we will be able to attend the conference face-to-face in the very near future.
