This paper presents a design of a batteryless and wireless system that can be used in hospitals to call nurses. Compared to actual nurse calling systems, the proposed transmitter neither needs batteries nor long wires to provide energy. Therefore, it is maintenance-free and can be easily installed. The key feature of the proposed system is that it will harvest its energy from motion. When a patient...
Today's world is communicating with cutting edge equipments which are using 3G/5G communication standards. With this it is possible to do multiple operation simultaneously with equipments are handheld mobile phone. The mobile systems are also using multiple communication standards like GSM, Bluetooth, Wi-Fi for interrupt free communication. Same technology can be used for operation of wireless control...
This paper presents the implementation of a flexible 4times4 MIMO testbed. The subsystems are designed and fabricated in RF section. Then, implementing the baseband section with FPGA and using the flexible MATLAB interfaces, the various performance studies are conducted. To validate the overall system performance, the measurement results are presented. The excellent agreement between the analytical...
