Patent number: 12191919Abstract: A body area network (BAN) architecture including a plurality of ultra-wideband (UWB) BAN node devices, a control node device, and a remote node device is described. The plurality of UWB BAN node devices measures real-time physiological data of a patient and transmits the physiological data to the control node device using UWB signals. The control node device encodes the UWB signals using an spectral amplitude coding-optical code division multiple access (SAC-OCDMA) encoder, modulates the encoded UWB signals using an on-off keying (OOK) scheme, combines the modulated UWB signals into an optical signal using an optical coupler, and transmits the combined optical signal through a free space optical (FSO) link to the remote node device. The remote node device decodes the combined optical signal using an SAC-OCDMA decoder, converts the decoded optical signal into an electrical signal, and analyzes the physiological data based on the electrical signal.Type: GrantFiled: August 13, 2024Date of Patent: January 7, 2025Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Khurram Karim Qureshi, Jawad Ahmad, Salman Ghafoor
