2 IP Traffic Continues to Increase Globally, IP traffic will grow 3-fold from 2014 to 2019, a compound annual growth rate of 23%. Global wired connections were 54% of total IP traffic in 2014, and will be 33% of total IP traffic in Source: Cisco Visual Networking Index (VNI), May 2015

3 WiFi Continues to Handle More Traffic Global WAP Wi-Fi was 42% of total IP traffic in 2014, and will be 52% of total IP traffic in Source: Cisco Visual Networking Index (VNI), May 2015

4 802.11ac Wave2 starting to actually exceed 1Gbps

5 Higher density of APs needed for performance Source: CISCO ac: The Fifth Generation of Wi-Fi Technical White Paper March 2014

6 802.11ac WAPs need a lot of POE power Faster speed require faster processors ~20W+ Most manufactures recommend POE+ or higher Source: Hubbell Cabling Infrastructure for Next Generation Wireless Access Points, ac and Beyond White Paper

7 What does this mean? 1. Wired connections are as important as ever 2. WAPs are mission critical connections 3. There are more WAPs to cable 4. Connections supporting Wireless and WAPs need to perform higher and support more power

9 TSB-162-A to the rescue TSB-162-A Updated November 2013 Supersedes TSB-162 dated March 2006 More than 30 organizations contributed in the development of this TSB

10 Scope This TSB provides guidelines for supporting wireless local area networks (WLAN) in customerowned premises; Topology Design Installation Testing of telecommunications cabling infrastructure

11 Cabling Cabling for wireless access points should be: balanced twisted-pair, category 6A or higher as specified in ANSI/TIA-568-C.2 lower temperature rise when remote power is applied two-fiber multimode optical fiber cable, OM3 or higher As specified in ANSI/TIA-568-C.3. to support higher data rates

12 802.11ac 2X 6A Recommended From CISCO Ethernet Cable Recommendation While the AP 1600/2600 and 3600 will work fine with CAT-5e for new cable installations, it is recommended that customers use CAT6a as this is the cabling required by the 10GE standard.

13 Cell Size Determination of exact cell size and placement of the wireless access point (WAP) is outside the scope of the TSB (perform a site survey or simulation)

14 Typical uniform cell size

15 Lmax Equation 18.3m (60 ft) 13m (42 ft) Lmax is the maximum equipment cord length between the EO and wireless access point; Lmax = R = X where R is the radius of the circle circumscribing the square cell; and X is the length of one side of the square cell. Lmax = R = * 18.3 Lmax = R = 13m Lmax = R = * 60 Lmax = R = 42ft

16 Hmax Equation The maximum length of the link from the crossconnect to the EO (Hmax) will depend on the size of the cell to be deployed. Solving for Hmax : Hmax = 96 (1 + D) Lmax m where Hmax does not exceed 90 m. D =.2 for 24awg D =.5 for 26awg Hmax = 96 (1 + D) Lmax Hmax = 96-(1 +.2) 13 Hmax = Hmax = 80.4 Hmax = ft Hmax = 80 m (262 ft) (max link length) 60 ft

17 Hmax Equation The maximum length of the link from the crossconnect to the EO (Hmax) will depend on the size of the cell to be deployed. Solving for Hmax : Hmax = 96 (1 + D) Lmax m where Hmax does not exceed 90 m. D =.2 for 24awg D =.5 for 26awg Hmax = 96 (1 + D) Lmax Hmax = 96-(1 +.2) 13 Hmax = Hmax = 80.4 Hmax = ft Hmax = 80 m (262 ft) (max link length) 60 ft

18 Hmax with equipment cord equation The total length of the horizontal channel, adjusted to allow for the use of the equipment cord in the cell is: Hmax + (1 + D) Lmax + 6 = 100 m Hmax + (1 + D) Lmax + 6 = 102m = 102 where Hmax is the maximum link length; and D is the insertion loss de-rating factor for the cord type (see ANSI/TIA-568-C.2). Lmax = R 60 ft Hmax = 80 m (262 ft) (max link length) 60 ft

20 IEEE802.3bt 4PPoE - 4-Pair High Power Maximum Power Levels 96W input Maximum PSE power set to 99.9W (LPS limit) and 57B (SELV limit is 60V) PD can expect at least 71W over C5e High power devices will operate with limited functionality with lower power Better cables allow for margin that CAN be utilized by PSE or used by PD for improved function Detailed considerations for backwards interoperability of PDs and PSEs 20

21 TIA-TSB-184-A for 4PPoE - Updated TSB to for IEEE requests Hubbell Chaired the Task Group developing TSB-184A Additional Guidance Category 8 Shielded C6A patch cords (26AWG) Higher maximum current (1.0A per pair) previously about 0.8A Detailed guidance on use cases and installation recommendations Smaller bundles Ambient conditions 21

22 TSB-184-A Guidelines for Supporting Power Delivery Over Balanced Twisted-Pair Cabling This TSB provides guidelines to enable the support of a wide range of safety extra low voltage (SELV) limited power source (LPS) applications using remote power supplied over balanced twisted-pair cabling. applications include LAN devices supported by IEEE Std 802.3bt Power, wireless access points, TIA-862-A building automation, and security devices such as remote cameras, IP telephones, and multimedia devices.

23 TSB-184-A Over Balanced Twisted-Pair Cabling Recommends CAT5e, or better, horizontal cabling DC Loop resistance and balance End-span and Mid-span configurations Tables of temperature rise within cable bundles References to safety standards The TIA has conducted tests with the higher current levels in cable bundles verifying that 4PPoE cabled infrastructure can be operated safely in the air handling space.

25 Power Options Typical wireless access point with remote power from a mid-span device

26 Power Options Typical wireless access point with local power

27 Mounting and Installation The manufacturer s guidelines for antenna types and installation locations should be reviewed as part of the planning and design function. One common theme regarding the deployment of wireless access points is the general need for the antennas to have an unobstructed transmission path to provide effective coverage.

28 Mounting and Installation Wall-mount below drop ceiling The wall mount below the drop ceiling option may provide for ease of installation. Such an installation allows access by building occupants and should be considered from a maintenance and security perspective.

29 Mounting and Installation In-the-grid ceiling mount The in-the-grid ceiling mount option provides the needed functionality in an aesthetically pleasing installation.

30 Patch Cords Horizontal cabling should not be connected directly to the wireless access point. The connection between the wireless access point and the EO should be made using a short equipment cord.

31 Use products rated for air handling spaces for plenum applications Plenum cable Plenum surface boxes Tested and rated with the jack as an assembly Plenum cords Made from plenum cable

32 What about multi-gigabit technology? 1, 2.5,5,and 10 Gbps in a single switch 1-5 Gbps over C5e or 6 10 Gbps over 6A POE available Plus Con Use existing cabling for current WAPs ax may have difficulty at 2.5 and 5 Gbps PoE delivery not as efficient as 6A

33 WAPs are now a critical application in the workspace

34 Performance and power delivery demands are only going to increase going forward

35 6A is the only current viable cabling standard that meets these demands
