Abstract

This paper presents a detailed measurement based characterization of the ultra wideband (UWB) channels in a data center environment and examines the accuracy of direct ranging using time of arrival (ToA)measurements. Modern data centers present a unique indoor environment that to our knowledge has not yet been characterized. Our ranging experiments indicate that it is possible to achieve an accuracy of fraction of a meter via direct ranging and point to the feasibility of locating individual servers using more sophisticated cooperative ranging.
