Cellular wireless or mobile communications have seen four generations of technological developments. Starting with analog voice with the first, and then moving on to digital voice with the second generation, these generations were each marked with a clear technological advancement. For the third generation, the advancement was in incorporating data on top of a voice-based infrastructure. With the fourth generation, every service was converted into data format, or packetized transmissions, including voice and video. Today, technologists are proposing a fifth generation for around the time frame of 2020. Most consider this time to be when the infrastructure will need to be renewed. Together with this observation, it is usually argued that the new generation technology should possess a number of features. Yet, there is really no consensus on what these new features should be. Some argue that we are facing a new generation of devices that will have continuous Internet connectivity, and with that there will be more machine to-machine or machine-type communications. It is further argued that, as a result, new communication protocols should be able to support the new formats of communication that this change will require. For example, it is argued that machine-type communication will require very low latency. Others argue that the demand for services will increase by about three orders of magnitude and the new technology should be designed to support this tremendous increase, perhaps handling each order of magnitude by means of a different approach. Yet, there are others who argue that the current communications infrastructure is highly energy-inefficient and the fifth generation should be designed to solve this problem, by increasing energy efficiency by several orders of magnitude. In this talk, we will discuss the pros and cons of the approaches for defining and realizing the fifth generation cellular wireless technologies as seen today. We will discuss what fifth generation can be expected to be and, more importantly, what it cannot be. The goal in this presentation is to address both the very high expectations and the realities.
Ender Ayanoglu received his Ph.D. degree from Stanford University, Stanford, CA in 1986 in electrical engineering. He was with the Communications Systems Research Laboratory, Holmdel, NJ, part of AT&T Bell Laboratories until 1996, and Bell Labs, Lucent Technologies from 1996 until 1999. During 1999-2002, he was a Systems Architect at Cisco Systems, Inc., San Jose, CA. Since 2002, he has been a Professor in the Department of Electrical Engineering and Computer Science, University of California, Irvine, Irvine, CA, where he served as the Director of the Center for Pervasive Communications and Computing and held the Conexant-Broadcom Endowed Chair during 2002-2010.
From 1990 to 2002, Dr. Ayanoglu served on the Executive Committee of the IEEE Communications Society Communication Theory Committee, and from 1999 to 2001, was its Chair. From 1993 until 2014 Dr. Ayanoglu was an Editor, and since January 2014 is a Senior Editor of the IEEE Transactions on Communications. He served as the Editor-in-Chief of the IEEE Transactions on Communications from 2004 to 2008. Since August 2015, he is serving as the founding Editor-in-Chief of the new journal IEEE Transactions on Green Communications and Networking.
Dr. Ayanoglu is the recipient of the IEEE Communications Society Stephen O. Rice Prize Paper Award in 1995 and the IEEE Communications Society Best Tutorial Paper Award in 1997. He received the IEEE Communications Society Communication Theory Technical Committee Outstanding Service Award in 2014. He has been an IEEE Fellow since 1998.
