공안 기관과 상용 무선 서비스 공급자, 그리고 무선 통신 사용자는 신뢰할 수 있는 실내 통신을 더욱 필요로 하고 있습니다. 한편 실내 무선 통신 환경에서는 일반적인 TETRA·P25·LTE를 기반으로 기존 공공 안전 통신(PSC) 네트워크를 사용할 수 없습니다. 건축 자재가 신호를 감쇠시켜 통신 신뢰성이 저하되기 때문입니다. 건물의 위성 신호도 약하기 때문에 GPS에 의한 지역화(포지셔닝) 기술도 적용할 수 없습니다. 따라서 야외 통신 채널을 실내로 확장하기 위해 특별한 방법을 개발해야 합니다.

실내 무선 통신 범위(수신 범위 확장)와 객체 위치 측정(Indoor Wireless Coverage and Objects Localization) 시장을 분석했으며 실내 무선 통신 문제 - 특히 긴급 대응 통신에 요구되는 조건과 주요 기술(스몰 셀, DAS 등)의 현재 개발·보급 동향, 구체 사례 관련 업계 동향, 주요 표준 기술 등의 정보를 정리하여 전해드립니다.

The report addresses specifics of wireless communications and localization technologies that support first responders and other users' activities inside of enclosures such as buildings, tunnels and similar structures. It also addresses related industries, applicable standards and markets.

Increasingly, public safety entities, commercial wireless service providers, and wireless users require reliable indoor communications. For public safety, reliable coverage is often essential throughout a broad jurisdiction, including coverage on-street, in-building, and in-tunnel. In such cases, there is no substitute for a properly designed dedicated mission-critical communications system with sufficient transmit sites to provide the level of signal required for reliable coverage anywhere within the jurisdiction, whether on-street or indoors.

Indoor wireless communications environments usually do not allow using traditional PSC networking based on TETRA, P25 or LTE. Building materials attenuate signals and this makes communications unreliable. Localization based on GPS techniques is becoming also questionable due to weak satellite signals inside of a construction.

All these factors make it necessary to develop special methods to extend outdoor communications channels inside of enclosures. Two such methods are analyzed in this report; and they are based on utilization:

  • Small Cells
  • DAS - Distributed Antenna Systems.

Small Cells base stations are small in size, lightweight and designed to serve up to several tens of users. They may be conveniently spread throughout a building, covering each corridor, hall, corners and so on. The technology relatively recently became commercialized and brought multiple benefits to users.

DAS is used for in-building signals distributions for at least twenty years. The report concentrates on advances in this technology, its specifics and issues.

Standard organizations activities, the in-depth market analysis and survey of the industry are also included in this report.

There are multiple methods suggested for in-building localization of first responders as well as other people or objects in the operational area. They are based on utilization of sensors, RF signatures in a building, amplification of GPS signals and other. The report concentrates on commercialized methods, and provides details of their advantages and issues. The report also addresses marketing aspects of in-building localization; and surveys patents related to indoor localization.

Specifics of indoors communications for the FirstNet - the first national PSC network - are detailed.

The report is written for a wide audience of technical and managerial staff involved in the development of reliable PSC and localization inside buildings and other enclosures.
