ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to prepare design and
construction bid documents for an enhanced Wi-Fi system at Seattle-Tacoma International
Airport for an amount not to exceed $1,946,000 out of a total estimated project cost of
$9,880,000. 
SYNOPSIS 
The Wi-Fi Enhancements project will replace an  existing,  outdated Wi-Fi system  used
throughout much of the Airport with a higher performing, wireless network with modern Wi-Fi
access points to better meet the needs of passengers, Airport tenants, and airlines. It will also
provide new ramp level Wi-Fi coverage at airport gates. The proposed technology enhancement 
will support current needs as well as the anticipated growth in the number of connected devices,
requirements for improved bandwidth for newer mobile devices, and extend much needed
coverage in the terminal and ramp. 
This project began as four separate Wi-Fi projects included in the 2014-2018 plan of finance
with a combined budget of $5,098,000 (CIPs C800585, C800622, C800624, and C800633).
During project definition, earlier budget estimates were refined, and staff decided to proceed
with a unified Airport-wide Wi-Fi project, with a larger scope, to be constructed in phases. The 
current estimated total project cost is $9,880,000. Staff expects to seek Commission
authorization for construction in 2015. 
BACKGROUND 
The existing Wi-Fi system at the Airport shares use of cellular radio equipment, which was
installed with the AT&T Wireless Distributed Antennae System (DAS) in 2004-2005. The DAS
has provided Wi-Fi coverage for the past decade but the design was optimized for cellular phone

Template revised May 30, 2013.

service and its Wi-Fi capabilities have become outdated. The Port assumed ownership of the
DAS-based Wi-Fi access points in 2009 as part of the AT&T contract. The DAS -based Wi-Fi 
infrastructure no longer meets the performance needs of the Airport's passengers and tenants for
Internet access, it has a limited coverage area, and it does not support the latest Wi-Fi network
standards. 
PROJECT JUSTIFICATION AND DETAILS 
An enhanced Wi-Fi system will be designed to better support public, business, and operational
needs throughout much of the Airport. The project will install network backbone infrastructure 
and Wi-Fi access points to provide high-speed, wireless Internet access in public areas used by
passengers in the Main Terminal, Concourses C and D, the South Satellite, and for Airport ramp
operation. 
There are two primary types of high-speed wireless access targeted by this project. 
The first type of high-speed wireless access will provide much improved Internet access for
passengers and tenants in public areas of the Airport. Mobile devices will connect to new
Wi-Fi access points installed inside the facility, which replace the existing distributed antenna
system's Wi-Fi access points in the terminal and concourses. The new Wi-Fi access points
enable higher bandwidth to the Internet, support more connected devices and comply with the
latest Wi-Fi standards used by today's mobile devices.
The second type will support airport, airline, and tenant operations outside the facility on the
ramp level at passenger loading bridges. The "ramp wireless network" will be accessed by
both handheld and vehicle-mounted mobile devices, and by new aircraft avionics systems.
The design of the enhanced Wi-Fi network will support Virtual Private Networks (VPNs) that
will be configured for secure Airport, airline, and tenant operations.
Project Objectives 
This project will provide high-speed, wireless Internet access throughout the main terminal,
concourses, and ramp with the exception at the North Satellite, which is anticipated to be 
included in future development plans for that facility. 
Scope of Work 
This project will plan and design an enhanced Wi-Fi system at the Airport that will provide highspeed
Internet access for mobile device users throughout Concourses C and D, the South
Satellite, GML Hall, Central Terminal, Ticketing and Security Checkpoints, the ramp's
passenger loading bridges,  and baggage make-up areas.  Improvements to the Wi-Fi
infrastructure for the North Satellite, and to Concourses A and B will be performed by other
projects. 
The table below identifies the location of Wi-Fi expansion, the type of equipment being installed
and the three projects that will expand Wi-Fi coverage to the ramp and inside the Airport's
public areas.

In general, the design will include a minimum of two Wi-Fi access points for each gate hold 
area, and three Wi-Fi access points at each gate ramp location. The ramp Wi-Fi system will
be supported by the installation of weather tight micro-distribution cabinets, which provide
network backbone connectivity for the ramp Wi-Fi access points. These will be installed on
the exterior of the building at the ramp level of concourses and South Satellite mounted on or
in close proximity to passenger loading bridges. Micro-distribution cabinets will provide the
infrastructure necessary for the ramp wireless network as well as other anticipated network
connectivity, e.g., future Closed Circuit TV (CCTV) coverage. Micro-distribution cabinets
will also provide the required network connectivity for Wi-Fi improvements to the interior of
Concourse C hold rooms.

Certain areas and functionality are not included within the above scope of work.
While Wi-Fi access points will be installed in hold rooms and aircraft gate areas, this
project will not install them within concessionaire lease spaces.  Wi-Fi service
improvements within concession spaces will be the subject of later requests to the
Commission within the Airport's dining and retail program authorizations. Newer
technology that is available within the marketplace to track movements of certain
individuals will not be installed as part of this project. As a result this project does
not increase concerns related to individual privacy.  Rather this project aims to
increase access to the Internet for the Airport's travelers and business customers.
The first phase of work will occur at Concourse C as a pilot project. The ramp micro distribution
cabinets at this location will provide support for the gate hold area Wi-Fi system as well. Once
completed, the Port will evaluate the functionality and serviceability of this system before
completing similar arrangements for ramp Wi-Fi throughout the Airport.

Lifecycle Cost and Savings 
The existing DAS-based Wi-Fi system has surpassed its useful life. Current demand for Wi-Fi
access results in poor performance, loss of connection, or no connection at all. It is anticipated
that an enhanced Wi-Fi system as currently envisioned will provide adequate capacity for the
foreseeable future. 
Although the enhanced Wi-Fi system provides significant performance improvements and better
coverage, renewal and replacement of the some of the network components will be required in
the three- to five-year time frame to keep pace with innovation in the wireless industry and
compliance with network standards. 
A software license and maintenance fee estimated increase of $20,000 will be budgeted in the
ICT Operating Budget. Recurring Port labor costs to maintain the system are not expected to
change as a result of this project. 
STRATEGIES AND OBJECTIVES 
This project support's the Port's Century Agenda objective of advancing this region as a leading
tourism destination and business gateway. Airport travelers and tenants have come to expect
high speed Wi-Fi access while moving through the Airport and while waiting for their flights. In
addition, airlines and Airport tenants are transitioning toward wireless transfer of data for their
business operations. Replacing the existing DAS-based Wi-Fi system with a new Wi-Fi system
will accommodate public, business, and operational expectations for the foreseeable future.

TRIPLE BOTTOM LINE 
Economic Development 
This Wi-Fi Enhancement project represents an investment in our current facilities and supports
the long-term vitality of the Airport, airlines, and Airport tenants. 
Environmental Responsibility 
This is a system internal to the Airport and will have a negligible effect on the environment. 
Community Benefits 
Wi-Fi Enhancement will increase high-speed data access for passengers and the traveling public
and improve customer service for Airport customers and tenants. The Project Manager and the
Office of Social Responsibility will work together to determine small business participation
opportunities, in accordance with small business Resolution No. 3618. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1)  Do nothing. Continue to rely on the existing DAS system for Wi-Fi access.
This alternative will not provide the level of wireless access service (accessibility, stability,
speed) expected by Airport customers now and in the future. This is not the recommended
alternative. 
Alternative 2)  Allow an ad-hoc development of new Wi-Fi connectivity by Airport tenants.
This alternative would not provide a consistent solution and could rely on outdated network
connectivity thereby not improving service. This is not the recommended alternative. 
Alternative 3)  Replace the existing DAS-based Wi-Fi system with a new high-speed Wi-Fi
system throughout the Airport ramp, main terminal, and concourses. This is the recommended
alternative.
