Device Connectivity Technologies Using Short-distance Wireless Telecommunication 田村俊哉 増田勲 あらまし Wi-Fi Bluetooth NFC TV TV Abstract Having seamless connectivity among digital devices in a multi-network environment is a key requirement in establishing the Human-Centric world proposed by Fujitsu. Better device connectivity with short-distance wireless telecommunication technologies such as Wi-Fi, Bluetooth and NFC provides users with appropriate services anywhere and in any situation in the fields of entertainment, health and communication. There are three types of device connectivity. The first is connectivity of audio-visual equipment that allows digital content in a smartphone to be sent to a TV, and then played on the TV; it also makes it possible to control content in a digital recorder with a smartphone and play it on a TV. The second is connectivity of in-vehicle apparatus that allows you to take a hands-free call and play back audio on in-vehicle apparatus. The third is connectivity of healthcare apparatus that allows you to easily collect data that are acquired with measuring equipment, accumulate data on a server in a network, and then utilize such data for medical care and fitness. This paper outlines short-distance wireless telecommunication technologies and shows our innovative application technologies for connectivity and interoperability among smartphones, audio-visual equipment, car navigation systems, and healthcare devices. 566 FUJITSU. 63, 5, p. 566-572 09, 2012
