First, the GPS and 4G data are merged to obtain outdoor positioning. By combining the artificial intelligence algorithm and WiFi and Bluetooth communication systems, the location of the medical device in the building can be identified. For the precise indoor-positioning scenario, the Angle-of-Arrival algorithm combined with the electromagnetic wave radiation characteristics are utilized. Finally, the data fusing technology combining the positioning information from the out-of-building, the in-building and the indoor scenarios is adopted via LoRa to achieve the ubiquitous positioning system. The power charging of IoT and wearable biomedical devices is crucial to the success of the applications. The technology of wireless charging by the use of an RF energy transmitter will be fist investigated. The long-term goal is to develop the intellectual property that can harvest the energy of the electromagnetic waves of WiFi, Bluetooth, and cellular phone signals to charge the extremely low-power devices. For the increasing demands on family medical monitor, low latency and high data rate communications are indispensable. Two 38-GHz beamforming systems, which suitable to the environment of precisely remote diagnosis, are proposed for 5G application. First two years we plan to create a PCB level discrete element based system. By virtue of former experiences, we will proceed the design on highly integrated CMOS chip.
