Arogyaswami Paulraj

Moving from India, Paulraj joined Stanford University faculty in 1992. His invention (1992) for exploiting multiple antennas at both ends of a wireless link (MIMO) lies at the heart of the current high speed WiFi and 4G and 5G mobile networks, and has revolutionized high-speed wireless services for billions of people. MIMO boosts data rate by creating parallel data streams, multiplying throughput by the number of antennas used. He ran a MIMO research program at Stanford for two decades before retiring in 2010. He founded three companies: Iospan Wireless for MIMO-OFDMA core technology (acquired by Intel), and Beceem Communications for 4G chips (acquired by Broadcom), have helped create a wireless technology eco-system now shipping billions of MIMO wireless devices annually. He founded Rasa Networks (acquired by Aruba /HPE) for using AI tools in WiFi network analytics.

Career in India Paulraj's contributions in India came whilst serving in the Indian Navy. In 1972, he developed new electronics for a British origin Sonar 170B. The technology was widely deployed in the Indian fleet. During 1977- 83, Paulraj led the development of a large surface ship sonar APSOH. This became the fleet sonar for the Indian Navy and its variants are still widely deployed. APSOH was a landmark achievement in Indian Electronics. Later, Paulraj founded three national-level research centers in India: the Center for Artificial Intelligence and Robotics, Defense R&D Organization, the Central Research Laboratories, Bharat Electronics, and the Center for Development of Advanced Computing, Dept. of Electronics (as co-founder). These labs are now a part of India's vast R&D infrastructure. He retired prematurely from the Indian Navy in 1991 with a rank of Commodore

Arogyaswami J. Paulraj (born 14 April 1944) is an Indian-American electrical engineer, academic. He is a Professor Emeritus in the Dept. of Elect. Engg. at Stanford University.

Paulraj was born in Pollachi near Coimbatore, British India in 1944, one of six children of Sinappan Arogyaswami and his wife Rose. He attended Montfort Boys' High School in Yercaud, Tamil Nadu.[1] He joined the Indian Navy at age 15 through the National Defense Academy, Khadakvasla and served the Indian Navy for 26 years. Paulraj received a B.E. in electrical engineering from the Naval College of Engineering, Lonavala, India, and a Ph.D. in electrical engineering from the Indian Institute of Technology, New Delhi, India
