An Advanced Uwb Channel Model for Body- Centric Wireless Networks
This paper presents a novel ultra wideband (UWB) channel model in the 3–10GHz range for body-centric wireless communications. The tests are performed in both indoor anechoic chamber environments, addressing on-body and off-body propagation scenarios. The body channel model is extracted by using a single spatial grid over all the body, and by distinguishing between LOS and NLOS condition. The la...
متن کاملUWB Channel for Wireless Body Area Networks at Hospital
Wireless body area networks (WBAN) are expected to be a breakthrough in healthcare, leading to concepts like “telemedicine” becoming real, since the sensor nodes in WBANs, communicating through wireless technologies, can transmit data from the body to a home base station, from where the data can be forwarded to a hospital, clinic or elsewhere, real-time. WBANs have not only the potential to inc...
متن کاملThe UWB Channel in Medical Wireless Body Area Networks (WBANs)
UWB is a technology that has several advantages when considered for a Wireless Body Area Network (WBAN). A WBAN is a network with its communications devices in very close proximity to the human body. In medical applications these devices are connected to sensors that can monitor vital signs such as ECG, temperature, and mobility. A WBAN allows for the remote monitoring of a patient’s health min...
متن کاملImpact of on-body channel models on positioning success rate with UWB Wireless Body Area Networks
In this paper, we aim to evaluate the positioning success rate of nodes placed on the body using different scheduling strategies at the Media Access Control (MAC) layer with Ultra Wide Band (UWB) Wireless Body Area Networks (WBAN) and under three different channel models. For this purpose, each node calculates its relative position with the estimation of its distances with the on-body anchors. ...
متن کاملUWB Channel Modeling for Wireless Body Area Networks in Medical Applications
Wireless body area networks (WBAN) are expected to be a breakthrough technology in healthcare areas such as hospital and home care, telemedicine, and physical rehabilitation. Because the human body has a complex shape consisting of different tissues it is expected that the nature of the propagation of electromagnetic signals in the case of WBAN to be very different than the one found in other e...
