8 Fundamentals: TIA-TSB-162-A Cabling Guidelines for Wireless Access Points

9 TSB-162-A Guidelines for Wireless Telecommunications Systems Bulletin TSB162-A Telecommunications Cabling Guidelines for Wireless Access Points (APs) Provides guidelines - Topology - Design - Installation - Testing of cabling infrastructure All to support the WLAN

10 TSB-162-A Guidelines for Wireless TSB-162-A states that cabling (for wireless access points) should be installed and performance tested per existing 568-C.2 standards. 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).

11 TSB-162-A Pre-Cabling Guidelines for Wireless Access Points 5,540 sq.ft. circular cell TO r=13m (42 ft) Lmax=13 m (42 ft) TO AP Hmax=80 m (262 ft) Patch=6m (20 ft) TR EQUIPMENT (switch) TO TO X=18.3 m (60 ft) Equipment in the Telecom Room TO Meeting room 3,600 sq.ft. square cell

12 TSB-162-A Pre-Cabling Guidelines for Wireless Access Points

13 TSB-162-A Cabling Guidelines for Wireless Access Points Accepts an in-the-grid ceiling mount, with antenna un-obstructed by ceiling tiles Accepts wall mount above or below suspended ceiling. Recommends a TE in the ceiling panel for locked security. Local power or PoE acceptable (end span or mid span) Horizontal should be terminated at E.O., then patch to AP Provide at least one Cat 6A cable to each AP location.

14 TSB-162-A Cabling Guidelines for Wireless Access Points Continued Consider maintenance and security of the APs. The use of an enclosure is recommended in areas where physical security is a concern. - Metal housing or non metallic housing, lockable - Hinged door for easy removal during upgrades - Low visual profile for aesthetics - Should provide knockouts for cable installation - Suitable brackets for wall or ceiling

15 Planning the Wired Infrastructure for Wireless LAN

16 Challenge Statement: Provide a wired infrastructure for a wireless LAN which will last for at least 15 years. Here are the BIG 6!

17 Challenge Statement: provide a wired infrastructure for a wireless LAN which will last for 15 years. Here are the BIG 6! 1) The access points will be physically swapped out every 3-5 years 2) The access point s throughput will increase by a factor of 10X every 5 years 3) The access point s power requirement, supplied by Power over Ethernet (PoE), will increase 4) The access point (AP) density will increase, requiring additional cabling to new AP locations 5) The wireless LAN will provide additional services in the future which are not clearly defined at this moment, including VoWiFi, location based services, telemetry and others. 6) Network PHY and MAC standards evolving

18 1) Why are access points going to be physically replaced every 3-5 years? Emerging wireless (IEEE ) standards Improvements in signal processing technology (I.E MU-MIMO versus SU-MIMO- see next slide) Improvements in throughput due to added unlicensed spectrum Emerging capabilities and features in the access point

19 SU-MIMO vs MU-MIMO 1 Continued Cisco will ride the ac Wave2, Bill Rubino, Cisco Mobility blog Single-User Multiple Input-Multiple Output (SU-MIMO) - 3 Spatial Streams (3SS) serve only 1 client at a time Multi-User Multiple Input-Multiple Output (MU-MIMO) User - 3 Spatial Streams (3SS) serve three 1 SS clients at a time

20 FCC Band allocations 5-6 GHz 1 Continued IEEE ac (both Wave 1 and Wave 2) provides: Over 500 MHz of bandwidth in the 5 GHz band - Choices Twenty-five Twelve Six Two 20 MHz channels 40 MHz channels 80 MHz channels 160 MHz channels (Wave 2 only) FCC may make an additional 250 MHz of bandwidth in the future!

21 1 Continued What s the functional difference between ac Wave 1 and Wave 2? Wave 1 products have been in use in the market for about 2.5 years. Wave 2 builds upon Wave 1 with some very significant enhancements: Supports speeds to 2.34 Gbps (up from 1.3 Gbps) in the 5 GHz band Supports multiuser multiple input, multiple output (MU-MIMO) Offers the option of using 160-MHz-wide channels for greater performance Offers the option of using a fourth spatial stream for greater performance Can run in additional 5-GHz bands around the world

22 IEEE ac 1 Continued What cable category is required to support the following? IEEE ac (both Wave 1 and Wave 2) IEEE a(x) Other technologies

23 Access Point Throughput 2) The access point s throughput will increase by a factor of 10X every 7.5 years, based on history Data Rate (Mb/s) PHY data rate TCP Throughput b a n ac Wave ac Wave ax Technology and Year

24 Wireless LANs - PoE's Killer App Power over Ethernet 3) WAP power is most often supplied by Power over Ethernet PoE is on the increase PoE IEEE 802.3af (802.3at Type 1) 2 Pairs 12.95W Exists today PoE+ IEEE 802.3at Type 2 2 pairs 25.5W Exists today PoE++ Proposed IEEE 802.3bt Type 3 4 pairs 49W 2016 Proposed IEEE 802.3bt Type 4 4 pairs 96W 2016 Non PoE standards based Cisco UPOE 4 pairs 60W exists today HDBaseT ( 4 pairs 96W exists today

25 Access Point Density 4) The access point density will increase, requiring additional cabling to new AP locations in the future High density Wi-Fi design is capacity-oriented, NOT coverage oriented AP density in many hotels and residence halls is 1 AP for each room (Best practice) Continued.

26 Access Point Density 4 Continued Per TIA 4966 Standard for Educational Facilities Use 1 AP for every 25 occupants of classroom or auditorium

27 Access Point Density 4 Continued How Will the access point be mounted to ensure optimum performance? Cabling and mounting the AP: - Suspended ceiling - Plenum - Open ceiling - Hard ceiling - On the wall - In high density environment such as an auditorium or stadium outdoors

28 Additional WiFi services 5) The wireless LAN will provide additional services in the future, which are not all clearly defined at this moment VoWiFi Already in force Location based services- higher AP density, 1>2,000sq ft Telemetry Blue tooth low energy (BLE) Cellular and small cell coverage (off loading) How will this impact the cabling and installation?

29 Additional WiFi services 5 Continued Mobile Voice, Minutes of Use by Technology Figures in parentheses refer to 2015, 2020 minutes of use share. Note: VoLTE and VoIP are mobile-specific; VoWiFi could be from any Wi-Fi connection. Circuit-switched mobile voice is excluded from the mix. Source: Cisco VNI Mobile, 2016

30 Standards Evolving 6) Network PHY and MAC standards evolving 1 Gb/s (CAT5e) and 10 Gb/s (CAT6A) standards Link aggregation more bandwidth, back up capabilities NBase-T- Industry effort to create 2.5 Gb/s and 5 Gb/s Ethernet over existing (CAT5e or CAT6) cable plant (802.3bz task force) - Life of cable plant may be extended by new NBase-T standards

31 WiFi Applications Part 2 Special considerations for different verticals - Hospitals - Schools - Hotspots - Large public venues and stadiums

32 WiFi in Hospitals TIA 1179 Healthcare Infrastructure Standard Hospitals have policies and procedures to mitigate Airborne Infectious Disease. ICRA procedure simplification (don t lift ceiling tiles) HIPPA Compliance (secure the endpoints) National Electric Code compliance (Plenum rated) BICSI 004 Supplemental Information- Guide to Medical Grade Wireless Utility

33 Problem Airborne Infectious Disease moves through plenum space to patient area through these gaps Gap in the ceiling Gap in the ceiling Gap in the ceiling Gap in the ceiling

34 WiFi in Hospitals Access Points mounted in ceiling enclosures permit : APs to be installed without poking holes in ceiling tiles Access to the access point without lifting ceiling tile Helps simplify ICRA protocols, and they are plenum rated

35 WiFi in Schools 45% of school districts lack sufficient Wi-Fi capacity to move to one-toone student-to-device deployments which is increasingly necessary to achieve modern digital learning objectives. In 2015, the FCC rebooted E-rate funding for robust Wi-Fi networks inside libraries and schools capable of supporting individualized learning Increasing the certainty and predictability of funding for Wi-Fi by expanding the five-year budget approach to providing more equitable support for internal connections known as category two through funding year 2019

36 WiFi in Schools Access Points can be recessed into the ceiling with recessed mounting kits to provide a secure, aesthetic, and professional installation.

37 WiFi Hotspots Globally, total public WiFi hotspots (including homespots) will grow sevenfold from 2015 to 2020, from 64.2 million in 2015 to million by 2020 Hotspots are installed to offer: Public WiFi at private homes and offices Cafés and restaurants, retail chains, hotels, Airports, transportation stations, public venues, office buildings, commercial spaces, etc. for customers and guests These installations must meet the physical security, access control, and aesthetics required for various venues

38 Hotspots Physically protect the WAP and antenna

39 Hotspots Mount access points in the preferred horizontal orientation - whether in the ceiling or on the wall - rather than flat on the wall. All leading AP manufacturers recommend this.

40 Recommendations Plan for high density WAP installations. A professional installation will provide the physical security, code compliance, and aesthetics mandated by the environment

41 WiFi in Large Public Venues and Stadiums Anticipate new or re-designed WiFi infrastructure in all such facilities over the next few years WiFi designs in such venues are extraordinarily challenging Special Considerations for Access Point mounting and protection Access Point Density Cabling Environmental protection

42 Large Public Venues Access points and directive antennas may be mounted on the wall to provide zones of coverage

43 Stadiums And finally, Access points may be mounted beneath the seats to create smaller cells of coverage
