The object
Arogyaswami Paulraj developed MIMO radio technology, using multiple transmit and receive antennas to carry parallel streams through the same wireless channel. That antenna-system architecture increased capacity and reliability in the physical radios behind high-speed Wi-Fi and 4G/5G cellular equipment.
01
What Arogyaswami did
Proposed and developed multiple-input multiple-output radio technology for transmitting parallel spatial data streams.
02
Why it matters
Stanford credits Paulraj’s MIMO work with laying the foundation for ubiquitous 4G/5G networks and high-speed Wi-Fi.
03
Living-status check
A September 2025 academy directory and Stanford’s current profile identify Paulraj as Stanford professor emeritus, providing recent positive living evidence.
