KT expands 5G work network hub service to public sector, applies to Gyeonggi provincial office

KT said on Sunday it has upgraded its 5G work network into a hub-based service to support flexible work environments for public-sector customers. The solution replaces wired 업무 infrastructure with a security-enhanced 5G wireless network that can apply an organisation’s internal security policies and be used without installing software. KT applied the model to the Gyeonggi provincial office, building key equipment at its data centre and opening linked networks for seven local governments.

Wireless charging uses up to 40% more power than wired, with heat and battery life also factors

Wireless smartphone charging can consume up to 40% more electricity than wired charging, using about 21Wh versus 15Wh to charge a phone from 0% to 100%, Engadget reported. Energy is lost as heat during electromagnetic power transfer and during AC-to-DC conversion. Higher temperatures can accelerate lithium-ion battery degradation. Wider adoption could lift overall power use, while safety and environmental burdens vary by product and usage conditions.
