"Perangkat implan medis memainkan peran penting sebagai perangkat medis karena manfaatnya dalam memantau dan mendeteksi gejalan penyakit. Pada perangkat implant medis yang bekerja secara nirkabel, dibutuhkan Wireless power dan data transfer (WPDT) sebagai alat komunikasi berdaya rendah antara implan dengan penerima di luar tubuh pasien. Namun, topologi rangkaian WPDT yang sederhana masih menjadi tantangan karena rangkaian WPDT yang sudah dikembangkan sebelumnya masih menggunakan rangkaian yang kompleks dengan dua tautan daya induktif untuk pengiriman daya dan data secara terpisah. Pada penelitian ini diusulkan rangkaian WPDT yang dapat mengirim daya dan data pada satu tautan daya induktif yang sama dengan menggunakan teknik modulasi amplitude-shift keying (ASK) sebagai metode pengiriman data. Pada rangkaian yang diajukan, tingkat efisiensi yang didapat sebesar 40,2% dengan daya terkirim ke beban sebesar 51,5 mW. Pada frekuensi pengiriman data 1 MHz; 1,5 MHz; dan 2 MHz bit error rate (BER) yang terukur kurang dari 10-8.
Medical implant devices play an important role as medical devices due to their benefits in monitoring and detecting disease conditions. In wireless medical implant devices, Wireless power and data Transfer (WPDT) is required as a low-power communication tool between the implant and an external receiver outside the patient's body. However, the simplicity of WPDT circuit topology remains a challenge as previously developed WPDT circuits still use complex circuits with two separate inductive power links for power and data transmission. This research proposes a WPT circuit that can transmit power and data over the same inductive power link using the Amplitude-Shift Keying (ASK) modulation technique as the data transmission method. In the proposed circuit, the achieved efficiency level is 40.2% with a power delivered to the load of 51.5 mW. At data transmission frequencies of 1 MHz, 1.5 MHz, and 2 MHz, the measured Bit Error Rate (BER) is less than 10-8"

"This book provides an overview of the latest research and development of new technologies for cognitive radio, mobile communications, and wireless networks. The contributors discuss the research and requirement analysis and initial standardization work towards 5G cellular systems and the capacity problems it presents. They show how cognitive radio, with the capability to flexibly adapt its parameters, has been proposed as the enabling technology for unlicensed secondary users to dynamically access the licensed spectrum owned by legacy primary users on a negotiated or an opportunistic basis. They go on to show how cognitive radio is now perceived in a much broader paradigm that will contribute to solve the resource allocation problem that 5G requirements raise. The chapters represent hand-selected expanded papers from EAI sponsored and hosted conferences such as the 12th EAI International Conference on Mobile and Ubiquitous Systems, the 11th EAI International Conference on Heterogeneous Networking for Quality, Reliability, Security and Robustness, the 10th International Conference on Cognitive Radio Oriented Wireless Networks, the 8th International Conference on Mobile Multimedia Communications, and the EAI International Conference on Software Defined Wireless Networks and Cognitive Technologies for IoT."
