CDL - Multiple Antenna Wireless – An Enduring Frontier

About the series


Multiple antenna (MIMO) wireless technology has been a spectacular success. MIMO is embedded both into 4G cellular and WiFi systems with many billions of devices added annually. MIMO multiplies wireless capacity by a factor of < 8 in current systems, but promises > 100 capacity expansion in a few years. The decade 1995-2005 was the golden decade of MIMO research when the theoretical foundations of currently deployed WiFi and 4G technology were developed. The MIMO concept has been broadened in recent years with closer linkages to medium access protocols and backhaul / fronthaul networking. Deployment of these new MIMO technologies are still a few years out.

This talk offers a personal perspective of MIMO technology.  Looking back, we trace the key ideas, enabling research and the road to widespread adoption. Looking forward, we outline MIMO’s new frontiers and their fresh challenges.

The talk will be easily accessible to a broad audience across CISE / NSF.


Paulraj is an Emeritus Professor (Research) at Stanford University. He earned a Ph.D. from the Indian Institute of Technology, New Delhi, India, in 1973.

After a 25 year R&D career with the Indian Navy, Paulraj joined Stanford University in 1991. He proposed the MIMO (Multiple Input Multiple Output) concept in 1992 which is the key to today’s 4G cellular and WiFi wireless networks.

Paulraj is an ISI Thomson most highly cited researcher with two textbooks on MIMO. He has graduated over 50 doctoral and post-doctoral students at Stanford.

In 1999, Paulraj founded Iospan Wireless Inc. and the company was acquired by Intel Corp in 2003.  Iospan pioneered MIMO-OFDMA used in 4G technology. In 2003, Paulraj co-founded Beceem Communications Inc. which became the leader in 4G / WIMAX chip sets. Beceem was acquired by Broadcom Corp. in 2010. He is currently doing a new start up in WiFi analytics.

Paulraj recognitions include the 2014 Marconi Prize and the 2011 IEEE Alexander Graham Bell medal. He is a member of seven national academies including the US National Academy of Engineering and the Royal Swedish Academy of Engineering Sciences. He is a fellow of IEEE, AAAS.  He has received a number of recognitions in India including the Padma Bhushan, the nation’s third highest civilian honor.

Paulraj is a Visiting Professor at the Beijing Institute of Posts and Telecommunications, Beijing and the Imperial College, London.
