Wi-Fi That Can Withstand a Nuclear Reactor: This receiver chip can take it (spectrum.ieee.org)

Researchers report a radiation-hardened 2.4 GHz Wi‑Fi receiver intended for robot communications inside nuclear reactors. The chip was tested to survive total doses up to 500 kilograys—far beyond typical space-electronics requirements—and its design changes include altering transistor materials and geometry to reduce radiation damage. The team is now working toward a two-way system by developing a more radiation-tolerant transmitter.
