Cabling Guidelines
for Wireless Access Points
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
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).”

TSB-162-A Pre-Cabling Guidelines for Wireless Access Points
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.
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
Planning the Wired Infrastructure
for Wireless LAN
Wired for Wireless
Challenge Statement: Provide a wired infrastructure for a wireless LAN which will last for at least 15 years. Here are the BIG 6!
Wired for Wireless 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
Wired for Wireless
1) Why are access points going to be physically replaced every 3-5 years? Emerging wireless (IEEE 802.11__ __) 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
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

IEEE 802.11ac (both Wave 1 and Wave 2) provides:
Over 500 MHz of bandwidth in the 5 GHz band - Choices Twenty-five 20 MHz channels Twelve 40 MHz channels Six 80 MHz channels Two 160 MHz channels (Wave 2 only)
FCC may make an additional 250 MHz of bandwidth in the future!

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

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

Wired for Wireless 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?

Wired for Wireless 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
WiFi Applications
Special considerations for different verticals
- Hospitals
- Schools
- Hotspots
- Large public venues and stadiums
Part 2
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
Gap in the ceiling Gap in the ceiling
Problem - Airborne Infectious Disease moves through plenum space to patient area through these gaps
Gap in the ceiling Gap in the ceiling
Wired for Wireless 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
WiFi in Schools
• 45% of school districts lack sufficient Wi-Fi capacity to move to one-to-one 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
Wired for Wireless WiFi in Schools
Access Points can be recessed into the ceiling with recessed mounting kits to provide a secure, aesthetic, and professional installation.
WiFi Hotspots
• Globally, total public WiFi hotspots (including homespots) will grow sevenfold from 2015 to 2020, from 64.2 million in 2015 to 432.5 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
Physically protect the WAP and antenna
Wired for Wireless 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.
Wired for Wireless Hotspots
• Plan for high density WAP installations. A professional installation will provide the physical security, code compliance,
and aesthetics mandated by the environment
Wired for Wireless Recommendations
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
Wired for Wireless
• Access points and directive antennas may be mounted on the wall to provide zones of coverage
Wired for Wireless Large Public Venues
And finally, Access points may be mounted beneath the seats to create smaller cells of coverage
