WUR (Wake-Up Radio)

Technical Explanation

Main cellular transceivers consume substantial energy even in idle mode just monitoring paging channels. 6G integrates Wake-Up Radio (WUR) technology. Devices feature an auxiliary nano-power receiver that consumes less than 1 microwatt. The main Sub-THz transceiver remains completely powered down in deep sleep until the WUR detects a specialized radio wake-up signature from the base station, extending device battery life from days to decades.

Key Functions

• Ultra-low power consumption (<1 microwatt) in continuous background listening mode
• Instantaneous sub-millisecond wake-up triggering for the main high-speed transceiver
• Extending smartphone, sensor, and wearable battery lifespans by up to 10x
• Mitigating continuous idle paging battery drain in dense cellular environments
• Native 3GPP physical layer synchronization and addressable wake-up packet formats
