With over 4 billion subscribers and the proliferation of smart phones, the impact of mobile wireless technology is both universal and transformative. This talk is a personal perspective on the evolution of mobile wireless standards and the underlying competitive, regulatory, technology and commercial factors that shaped their evolution, including the rise of LTE and the eclipse of WiMAX. The talk will then focus on the rapidly increasing demand for higher network capacity and reliability. We explore several approaches to address this challenge, arguing that some seemingly obvious solutions face difficulties. We end with a discussion of Hyper – MIMO and why it may be the key to meeting future needs.

Arogyaswami Paulraj

Stanford University


Dr. Paulraj is an Emeritus Professor at Stanford University and a Senior Adviser to Broadcom Corporation. He graduated with a B. Eng. from the Naval Engineering College, Lonavala, India, in 1966 and with 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 1992. He proposed the concept of spatial multiplexing / MIMO in 1992. MIMO technology is the key to today’s wireless broadband networks like 4G cellular and WiFi. In 1999, Paulraj founded Iospan Wireless Inc. and the company was acquired by Intel Corp in 2003. Iospan was the first company to develop MIMO-OFDMA technology, which is now adopted by all 4G wireless systems. In 2003, Paulraj co-founded Beceem Communications Inc. which built WiMAX semiconductors and was acquired by Broadcom Corp. in 2010. In India, prior to 1992, he led the development of the world-class APSOH sonar, one of India’s most successful military development projects. He also founded three laboratories in areas spanning High Speed Computing, AI and Robotics and Communications / Sensing. These labs have grown into large national R&D centers in India. Paulraj has received several recognitions in the US including the 2011 IEEE Alexander Graham Bell medal. He is a member of five national academies including the US National Academy of Engineering. He is a fellow of IEEE and AAAS. In India he has received several national awards including the Padma Bhushan, one of the highest civilian awards, in 2010.
