Abstract
This report addresses advances in localization of wireless objects in the
emergency situations.
The report covers both technological and marketing issues of such a process.
It consists of two major parts:
- -Part I: E911/E112 services, technologies and markets. We compare here
various methods to determine location of a cellular caller in emergency
situations, discuss the market and services.
- -Part II: Ultra Wideband (UWB) technology as an assistant to first
responders in localization various objects in the emergency situations. Here,
we focus on UWB as an important tool, which introduces many advanced features
to first responder's communication and radar abilities.
The service and the E911/E112 industry were born in response to growing the
cellular subscriber base and inability traditional 911/112 service to support
reliable caller's identification and location. Realizing the importance of
this service for people in critical situations, the governments around the
world, and particular in the U.S. mandate the phase approach to redefining 911
for mobile users.
The report addresses a complex of issues associated with the technological
challenges and the markets for E911/E112. It also provides information on the
FCC activity in this area. We cover in this report: a. E911 technologies,
services and regulations, and b. E91/E112 markets, vendors and providers. The
report also contains a detailed list of terminology used in the E911/E112
world.
The report discusses issues associated with E911/E112 importance, and why the
governments mandated the implementation of these emergency services. In
technology sections, the report provides the analysis of various approaches to
E911/E112 implementation, compares such approaches and provides their benefits
and limitations. In the market sections, the analysis of the E911/E112 market
is presented; portfolios of the major vendors are analyzed.
In the second part of the report, we provide the details of advantages to use
UWB devices for first responders operations. Such operations very often are
conducted in the areas where other localization techniques (such as GPS) are
not effective. With UWB, first responders may achieve object localization with
precise accuracy and with visibility through walls, doors and so on.
