description Arogyaswami Paulraj Overview
Arogyaswami Paulraj is an Indian-American electrical engineer and professor emeritus at Stanford University. He is recognized for his invention of multiple-input multiple-output (MIMO) technology, a method of using multiple transmitting and receiving antennas to dramatically increase the data capacity of wireless communication channels. MIMO has become a foundational component of modern wireless standards, including Wi-Fi and 4G LTE.
help Arogyaswami Paulraj FAQ
What exactly did Arogyaswami Paulraj invent?
Paulraj pioneered the practical use of multiple-input multiple-output, or MIMO, antenna systems for wireless communications. MIMO sends and receives multiple data streams over the same radio channel, increasing capacity without requiring a proportional increase in spectrum.
Where is MIMO technology used today?
MIMO is a foundational technique in Wi-Fi and modern mobile networks, including 4G and 5G systems. Devices use multiple antennas and signal-processing algorithms to improve speed, reliability, or both.
What did Paulraj work on before joining Stanford?
Before his Stanford career, Paulraj served in the Indian Navy and worked on advanced sonar systems. He led development associated with APSOH, an indigenous shipborne sonar effort in India.
Which major award did Arogyaswami Paulraj receive for MIMO?
Paulraj received the 2014 Marconi Prize for his pioneering contributions to MIMO wireless technology. He has also been recognized by organizations including the IEEE and India's national honors system.
