26、s not part of the TSB) This Telecommunications Systems Bulletin (TSB) was developed by TIA Subcommittee TR-42.1. Approval of this TSB This TSB was approved by TIA Subcommittee TR-42.1 and TIA Engineering Committee TR-42. Contributing organizations More than 30 organizations within the telecommunicat

27、ions industry (including manufacturers, consultants, end users, and other organizations) contributed their expertise to the development of this TSB. Documents superseded This TSB supersedes TSB-162 dated March, 2006. Significant technical changes from the previous edition Significant changes from th

28、e previous edition include: References were updated. The terminology was changed to use the generic terms from ANSI/TIA-568-C.0. The maximum link length calculations were modified to account for different equipment cord types. Information was added concerning the use of multiple EOs for a single acc

29、ess point. The use of category 6A balanced twisted-pair cabling or OM3 optical fiber cabling is now recommended. Information on separation of power branch circuits and telecommunications cabling was removed. This information can be found in ANSI/TIA-569-C or relevant premises stand-ards. Additional

30、information was added on wireless access point mounting options. Detailed derivation of link insertion loss limits was removed. This information can be found in ANSI/TIA-568-C.2. Information was added on physical security for wireless access points. A bibliography was added. Annexes There are two an

31、nexes to this TSB. Introduction A growing number of enterprises employ equipment at the “edge” of the network that relies on cabled connections to the cabling infrastructure at the work area, while also having the ability to maintain mobile and portable network access at other locations. A wireless

32、access point is a device that provides connectivity to other wireless devices within its coverage area and also provides interconnection to a wired network. The current suite of TR-42 infrastructure and ca-TSB-162-A iv bling standards do not specifically cover cabling to wireless access points. Supp

33、lementary in-formation on the number of outlets and outlet placement for wireless access points may aid in the provisioning of wireless networks. This TSB provides design and installations guidelines for pre-cabling in a grid approach that al-lows the user flexibility when deploying wireless access

34、points. The pre-cabled grid makes the building ready for wireless access points to be installed at any time. Additionally, wireless ac-cess point locations can be “fine tuned” by moving the wireless access point within each cell of the pre-cabled grid as necessary. This TSB is primarily focused on n

35、ew buildings that are in the planning stage where pre-cabling in a grid approach is recommended. This approach can also be used in existing buildings where applicable. Site surveys are also advantageous for existing empty buildings, as well as for build-ings that have been occupied and furnished. Pr

36、edictive analysis of facilities can also provide useful information as the planned building construction type and materials can be analyzed for wireless coverage prior to or during construction. The guidelines in this document may be used to provide cabling for wireless local area networks (WLANs) i

37、n locations including: commercial buildings educational facilities healthcare facilities restaurants hotels industrial facilities places of assembly There are locations where the installation of a WLAN is not recommended (e.g., secure facili-ties) due to concerns with RF interference and security.

Stewardship Telecommunications infrastructure affects raw material consumption. The infrastructure design and installation methods also influence product life and sustainabilit

39、y of electronic equipment life cycling. These aspects of telecommunications infrastructure impact our environment. Since building life cycles are typically planned for decades, technological electronic equipment up-grades are necessary. The telecommunications infrastructure design and installation p

40、rocess magnifies the need for sustainable infrastructures with respect to building life, electronic equip-ment life cycling and considerations of effects on environmental waste. Telecommunications designers are encouraged to research local building practices for a sustainable environment and conserv

41、ation of fossil fuels as part of the design process. Metric equivalents of United States customary units The dimensions in this TSB are metric or United States customary with approximate conver-sions to the other.

42、this TSB are subject to revisions and updating as warranted by advances in building construction techniques and telecommunications technology. TSB-162-A 1 1 SCOPE This TSB provides guidelines on the topology, design, installation, and testing of telecommuni-cations cabling infrastructure, in complia

43、nce with ANSI/TIA-568-C.0 and ANSI/TIA-569-C, for supporting wireless local area networks (WLANs). This TSB describes the cabling between lo-cal area network (LAN) equipment and wireless access points including pathways and spaces to support the cabling and wireless access points. 2 REFERENCES The f
