Assessment of Technologies and Markets for Wireless Emergency Services

The service and the E911 industry were born in response to growing the cellular subscriber base and inability traditional 911 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 technologies and the markets for E911. It also provides information on the FCC activity in this area. The report consists of two major parts: 1. E911 technologies, services and regulations, and 2. E911 markets, vendors, providers. The report also contains a detailed list of terminology used in the E911 world.

In the first part, the report discusses issues associated with E911 importance, and why the governments mandated its introduction. In technology sections, the report provides analysis various approached to E911 implementation, compares such approaches and provides their benefits and limitations. In the market sections, the analysis of the E911 market is presented; portfolios of the major vendors are analyzed.

Report is written for the technical staff of organizations involved in the E911 development and planning. It is also useful for the vendors of E911 equipment who can find in it techniques comparison, information on competition and the markets.
