Wiring for Wireless. TM Fundamentals: TIA-TSB-162 -A Cabling Guidelines for Wireless Access Points
TSB-162 -A –Guidelines for Wireless Telecommunications Systems Bulletin TSB 162 -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 5, 540 sq. ft. circular cell Lmax=13 m (42 ft) TO AP Hmax=80 m (262 ft) TR TO r=13 m (42 ft) Patch=6 m (20 ft) EQUIPMENT (switch) TO TO TO Meeting room 3, 600 sq. ft. square cell X=18. 3 m (60 ft) Equipment in the Telecom Room
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 Po. E acceptable (end span or mid span) • Horizontal should be terminated at E. O. , then patch to AP • Provide at least one Cat 6 A 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 Wiring Infrastructure for Wireless LAN
Wiring for Wireless. TM Challenge Statement: Provide a Wired infrastructure for a wireless LAN which will last for at least 15 years. Here are the BIG 6!
Wiring for Wireless. TM 6 facts to consider: 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 10 X every 5 years 3) The access point’s power requirement, supplied by Power over Ethernet (Po. E), 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 Vo. Wi. Fi, location based services, telemetry and others. 6) Network PHY and MAC standards evolving

Wiring for Wireless. TM Standards Evolving 6) Network PHY and MAC standards evolving Ø 1 Gb/s (CAT 5 e) and 10 Gb/s (CAT 6 A) standards Ø Link aggregation – more bandwidth, back up capabilities Ø NBase-T- Industry effort to create 2. 5 Gb/s and 5 Gb/s Ethernet over existing (CAT 5 e or CAT 6) cable plant (802. 3 bz task force) - Life of cable plant may be extended by new NBase-T standards
Wi. Fi Applications Part 2 Special considerations for different verticals - Hospitals - Schools - Hotspots - Large public venues and stadiums
Wi. Fi in Hospitals • TIA 1179 – Healthcare Infrastructure Standard • Hospitals have policies and procedures to mitigate Airborne Infectious Disease. Ø ICRA procedure simplification (don’t lift ceiling tiles) Ø HIPPA Compliance (secure the endpoints) Ø National Electric Code compliance (Plenum rated) • BICSI 004 Supplemental Information- Guide to Medical Grade Wireless Utility
Problem Airborne Infectious Disease moves through plenum space to patient area through these gaps Gap in the ceiling
Wiring for Wireless. TM Wi. Fi in Hospitals Access Points mounted in ceiling enclosures permit : Ø APs to be installed without poking holes in ceiling tiles Ø Access to the access point without lifting ceiling tile Ø Helps simplify ICRA protocols, and they are plenum rated
Wi. Fi 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
Wiring for Wireless. TM Wi. Fi in Schools Access Points can be recessed into the ceiling with recessed mounting kits to provide a secure, aesthetic, and professional installation.
Wi. Fi Hotspots • Globally, total public Wi. Fi 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 Wi. Fi 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
Wiring for Wireless. TM Hotspots Physically protect the WAP and antenna
Wiring for Wireless. TM Hotspots Ø 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.
Wiring for Wireless. TM Recommendations • Plan for high density WAP installations. A professional installation will provide the physical security, code compliance, and aesthetics mandated by the environment
Wiring for Wireless. TM Wi. Fi in Large Public Venues and Stadiums • Anticipate new or re-designed Wi. Fi infrastructure in all such facilities over the next few years • Wi. Fi designs in such venues are extraordinarily challenging • Special Considerations for • Access Point mounting and protection • Access Point Density • Cabling • Environmental protection
Wiring for Wireless. TM Large Public Venues • Access points and directive antennas may be mounted on the wall to provide zones of coverage
Wiring for Wireless. TM Stadiums And finally, Access points may be mounted beneath the seats to create smaller cells of coverage
