The iPhone 6 and almost all the flagship Android phones that you can buy this year come with very high-speed Wi-Fi and LTE mobile telephone bands which make them capable of downloading data at speeds up to 100 Mbps. The man who made this possible is Arogyaswami Paulraj, Professor Emeritus at the Department of Electrical Engineering at the Stanford University and who has served in Indian Navy for 30 years. Paulraj joined the Navy at the age of 15. He received a bachelor’s degree in electrical engineering from the Naval College of Engineering, Lonavala and his doctorate in the same discipline from IIT-Delhi. Among other things he has been the founding director of three major labs in Bangalore—the Center for Artificial Intelligence and Robotics, the Center for Development of Advanced Computing and the Central Research Labs of Bharat Electronics. After leaving Indian Navy in 1991, he started work at the Stanford University and in 1992 came up with the idea for a very innovative technology. Called MIMO (Multiple input, multiple output), it called for multiple antennas at both receiving stations and transmitting stations. Two decades later, MIMO has become one of the core technologies of mobile telephony and in 2014 would win Paulraj the prestigious Marconi prize.
