Radiation-hardened (Rad-Hard) radio frequency chips (such as Qorvo QM34100) support dual bands of 2.4GHz/5GHz, can resist interference, and ensure secure data transmission (with a rate of up to 1Gbps) in combat zones.

Low-power microcontrollers (Texas Instruments MSP430FR5994) can operate within a wide temperature range of -55°C to 125°C, powering handheld radio devices and battlefield Internet of Things nodes, with a battery life of more than 72 hours.
