Question

what is the most recent communication technologies available to us?​

Answer 1

5G is the fifth generation of cellular mobile communications, following the 4G (LTE/WiMax), 3G (UMTS), and 2G (GSM) systems. 5G represents a fundamental shift in communication network architectures, promising more bandwidth with lower latency. Theoretically, 5G can be 20 times faster than 4G. These are the most recent one technologies available to us.

Among the more significant events in the recent history of long-distance communication have been the building of computer-based communication networks and the development of technologies that have made possible the implementation and exploitation of these networks. In this chapter we focus on these technologies and on the challenges and opportunities for human factors research that they present.

We begin with a brief historical overview of computer-communications networking technology. We then focus on current trends, especially the phenomenon of "global connectivity" that networking is coming to represent and some of the implications this could have. In the remainder of the chapter we discuss some of the human factors issues and research needs that relate to networking and its future development and applications.
