Recent advances in wireless communication technologies have had a transforma-
tive impact on society and have directly contributed to several economic and social
aspects of daily life. Increasingly, the untethered exchange of information between
devices is becoming a prime requirement for further progress, which is placing an
ever greater demand on wireless bandwidth. The ultra wideband (UWB) system
marks a major milestone in this progress. Since 2002, when the FCC allowed the
unlicensed use of low-power, UWB radio signals in the 3.1–10.6GHz frequency
band, there has been significant synergistic advance in this technology at the cir-
cuits, architectural and communication systems levels. This technology allows for
devices to communicate wirelessly, while coexisting with other users by ensuring
that its power density is sufficiently low so that it is perceived as noise to other
users.

This book is focused on designing and developing Representational State Transfer (REST)
platforms in Rails. REST is the architectural style of the Web, consisting of a set of
constraints that, applied to components, connectors, and data elements, constitute the
wider distributed hypermedia system that we know today: the World Wide Web.
There are a few good reasons why it makes more sense to build platforms instead of just
products or applications. Platforms are like ecosystems interconnecting different
applications, services, users, developers, and partners. Platforms foster innovation through
the inputs of their direct collaborators. By providing application programming interfaces
(APIs) and software development kits (SDKs), platforms are more customer driven.
