Abstract

The world of wireless data is dominated by in-building subscribers who also require seamless reception of radio signals outdoor and indoor. Unlike the demands of previous generations' wireless ‘voice-only' services, new-age in-building wireless data demands cannot be met by relying only on the external/macro network-QoS requirements and capacity issues preclude this. The immediate need is for dedicated, purpose-built in-building RF coverage systems with the capacity to meet today' s building occupant needs, and the room to grow to meet those of future occupants. Among other in-building communications applications, Public Safety Communications (PSC) posses a special role:

PSC special needs require extended building coverage in the areas such tunnels, basements and other that may be in no interest to other groups of subscribers; In-building communications is also required to be integrated into the uniform class of channels to seamlessly extend first responder outdoor radio communications; Traditional in-building RF coverage extenders can be damaged even before first responders arrival; responders have to rely in a great degree on temporary network solutions (such as, for example, mesh structures).

Many P25 and TETRA networks were planned and deployed, providing the necessary outdoor coverage and capacity; at the same time, seamless coverage to the indoor environment was considered as a secondary requirement. Now, the availability of robust indoor coverage has become a significant competitive advantage for network operators.

Public Safety networks that cannot guarantee coverage in federal, state and local government agency facilities as well as primary private and public venues, have a severely limited value in supporting first responders operations.

This report addresses public safety issues, analyzing the markets and technologies for first responders' in-building communications. This includes:

One of the primary candidates for in-building radio support-we analyzed the Ultra Wideband technology role. UWB gives first responders a single gear with ability of radar, communications and location. This technology supports high-speed communications in the condition of multi-path interference, which is usually a case inside of any building or tunnel structures. Mesh topologies-these topologies allow building-distributed, self-organized and self-healing communications channels. Inside of a building, each first responder may become a node of such a network, which is temporary and can function only during a particular public safety operation. Distributed Antenna System (DAS)-this system can extend outdoor RF coverage inside of a building to places that are the most important to first responders (staircases, corridors, basements) activity during an incident.

The report provides details of each technology and market statistics for several applications, including public safety communications.

Research Methodology

Considerable research was done using the Internet. Information from various Web sites was studied and analyzed; evaluation of publicly available marketing and technical publications was conducted. Telephone conversations and interviews were held with industry analysts, technical experts and executives. In addition to these interviews and primary research, secondary sources were used to develop a more complete mosaic of the market landscape, including industry and trade publications, conferences and seminars.

The overriding objective throughout the work has been to provide valid and relevant information. This has led to a continual review and update of the information content.

Target Audience

This report is important for the government agencies involved in the first response to critical situations. It is necessary for technical departments of such agencies to have a document, which explains the radio technology and architectures of networks supporting public safety communications inside of buildings, tunnels and similar structures. They also need to have market statistics and to know the major players and their portfolios to select the right equipment.

For vendors, this report provides valuable information on competition. It also supports these vendors with the market assessment. For building owners and network providers this report may provide information on additional sources of revenue from in-building communications.
