High speed intelligent communication for tele-care early warning system-a survey

Aging problem is a crucial issue nowadays. The population of old persons of age more than 65 will achieve 20% in Asia area in 2020. To care these aged persons, one of the important things is to provide early warning of the physical improper situations before it is too late to be warned by themselves. The intelligent high speed tele-care system could be a solution. It includes design, and implementation of low profile, short distance, high speed intelligent sensor network with high data rate communication, and modern signal processing techniques. The technologies behind is to promote high speed chip designs and to enhance the smart system command and control capability. A novel intelligent communication topology with smart-suit for body kinematics, blood pressure, heart beat rate and breath monitoring is presented. The prominent characteristic of the structure is that data source for every communicating unit can be determined by its current sensing state. Propagation delay is reduced and transmitting speed is improved. The topology fits to be adopted in a complex communication system, contributing to threshold control and integrated management for the early warning. Modern technologies and experimental waveforms are presented.
