Implementation of Ultra-Wideband (UWB)
Sensor Nodes for WBAN Applications
K. M. S. Thotahewa, Jean-Michel Redouté and Mehmet Rasit Yuce
Abstract Wireless body area networks (WBAN) applications benefit extensively
from the advantages offered by the unique features of ultra-wideband (UWB) wireless
communication. This chapter focuses on the hardware implementation of UWB-
based sensor nodes for WBAN applications. Different realizations of UWB sensor
node architectures are described and a critical analysis of their suitability for WBAN
applications is presented. Implementation of narrowband (NB)-based WBAN sys-
tems that can be found in the literature is discussed in order to compare their
performance with the UWB systems. The design techniques for the implementation
of an impulse radio UWB (IR-UWB) sensor node are presented paying attention to
the UWB pulse generation and data modulation.

Introduction
The ability to remotely monitor patients has many benefits because it is presenting
a solution to the increasing demand for physical infrastructure at hospitals. With the
use of mobile health facilities, the requirement of patients being physically present
in a care providing environment is eliminated. Vital physiological information can
be transferred to a remote database via internet using remote health monitoring
[ 1 ]. Because the patients are monitored in real time while being involved in their
day to day activities, physiological parameters give a more realistic overview of the
patient's health status. Consider, as an example, a patient suffering from a high blood
pressure. If it is possible to remotely monitor his/her blood pressure throughout the
