1.1.1 Trends Affecting DAS 1.1.1.1 Building Design and Construction Since the 1990s, there has been an increasing focus of integrating sustainable practices into building design and construction. Defined within Leadership in Energy and Environmental Design (LEED), Energy Star ® , and other programs are requirements and recommendations that encourage the reuse of existing buildings, which will often block effective RF transmission penetrations through the outer shell, throughout a floor, or between floors within the interior space of a building. A DAS is one means to enable wireless services for new building tenants. NOTE: Methods to reduce or eliminate thermal radiation through windows are effective at reducing or blocking most types of wireless transmission since microwave and other RF frequency bands fall under the broader spectrum of thermal radiation. The macro network is becoming less and less able to deliver ubiquitous service as the number of buildings or the height of buildings in a given area increases. Both obstructions and elevated noise levels demand higher levels of signals than can be generated by conventional macro cellular base stations. 1.1.1.2 Public Safety and Services Legislative developments have seen the creation of requirements for public safety wireless systems in the form of NFPA 1, Fire Code, NFPA 72, National Fire Alarm and Signaling Code, and the latest edition of the International Building Code. Adoption of these codes and their requirements is ongoing, and this is a trend that is expected to increase in the future. As technology is increasingly integrated into safety and security services, additional capabilities and new functionalities become possible. With these advances in function, communication with a building’s surveillance, fire detection/suppression, and access control systems by police, fire, and other personnel are now possible.
1.2 Purpose The purpose of this standard is to afford designers and installers an opportunity to enhance their knowledge of quality DASs, understand the requirements of superior performing systems, and provide requirements and recommendations for the design and installation of standards-compliant, vendor-neutral systems. 1.3 Categories of Criteria Two categories of criteria are specified—mandatory and advisory: • Mandatory criteria generally apply to protection, performance, administration and compatibility; they specify the absolute minimum acceptable requirements. • Advisory or desirable criteria are presented when their attainment will enhance the general performance of the system in all its contemplated applications. Mandatory requirements are designated by the word shall; advisory recommendations are designated by the words should, may, or desirable, which are used interchangeably in this standard. Where possible, requirements and recommendations are separated to aid in clarity. Notes, cautions, and warnings found in the text, tables, or figures are used for emphasis or for offering informative suggestions. 2 Scope This standard provides industry and service provider neutral requirements and acceptable best practices for the design and installation of DAS. For brevity, as used in this document, the terms distributed antenna system or DAS includes other in-building wireless and similar systems, such as radiating cable and small-cell networks, unless these systems are specifically described. The document will address, at minimum, the following: • A description of a typical DAS • Components used within a DAS • Types of host systems (2-way voice, cellular, LTE, public safety, business band, analog, digital, other) • Compliance and integration with existing related codes and standards and other legal concerns • Coordination with the host system owner(s) • RF system design methods • Telecommunication infrastructure design • Installation and commissioning methods
3 Required Standards and Documents The following standards and documents contain provisions that constitute requirements listed within this standard. Unless otherwise indicated, all standards and documents listed are the latest published version prior to the initial publication of this standard. Parties to an agreement based on this standard are encouraged to investigate the possibility of applying a more recent version as applicable. Where equivalent local codes and standards exist, requirements from these local specifications shall apply. Where reference is made to a requirement that exceeds minimum code requirements, the specification requirement shall take precedence over any apparent conflict with applicable codes.
