The present disclosure may be applied to intelligent services based on the above technologies, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Disclosed are an apparatus and method for generating distress signals in a mobile device. The apparatus comprises a coil antenna for NFC communication, a first communication circuit configured to perform the NFC communication using the coil antenna in a normal mode, a second communication circuit transmitting a distress signal having a rescue-dedicated frequency through the coil antenna in a distress mode, a switch connecting the coil antenna to the first communication circuit or the second communication circuit, and a processor determining the normal mode or the distress mode to control the switch."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for generating distress signal","description":"The present disclosure relates to a sensor network, Machine Type Communication (MTC), Machine-to-Machine (M2M) communication, and technology for Internet of Things (IoT).
