AT&T’s Campus-wide Wireless Solution

•AT&T works to maximize the wireless coverage and capacity on a campus through the use of macro facilities, a distributed antenna system (DAS) architecture, and strategically placed small cells.

•The net effect of using all of the tools in the toolbox is to provide an optimal cost solution that will be easier to fund and will be acceptable to carriers.

•This will in turn ensure that there is real and sustained benefit for the campus and its visitors, all the while ensuring maximum participation from the carriers providing that benefit.

Total Campus Coverage

Macro System/High Power Outdoor DAS (oDAS):

• The design of the macro system (stealth antennas on a roof) and use of high power oDAS can provide the optimum overall coverage and capacity for the campus.

• The macro makes strategic use of existing structures on campus in an architecturally appropriate and sensitive manner.

• The oDAS makes use of shared, neutral host infrastructure on facades of buildings and vertical structures (like light standards) to propagate the signal.

Indoor DAS (iDAS):

• An iDAS supplements the Macro/oDAS coverage to provide more robust voice & data wireless service within structures that have a high concentration of wireless users or in situations where building construction methods or materials impair wireless service in specific areas.

Small Cells: • Small cells are used where additional supplemental coverage or capacity is

needed and iDAS is not a cost effective solution.

Comparing In-Building Solution options


Repeaters* Repeaters (also called BDA or bi-directional amplifier) are used in small (<100K sq. ft) venues to expand coverage. A repeater uses a rooftop antenna draw capacity from a nearby macro cell site as the RF source and rebroadcasts the signal throughout the facility. Donor cell site capacity is shared with external traffic and is not dedicated to the venue. DAS antennas and splitters provide coverage to various locations inside the building from the input of the BDA.

Base Transceiver Station (BTS) The Macro BTS is the RF source primarily used in the macro network. For in-building applications, BTS are expensive and require dedicated backhaul, but offer a coverage & capacity solution that can support a large number of users over a wide area.

Distributed Antenna System (DAS) The DAS distributes the RF signal across antennas that are installed throughout the facility. A Small Cell, BDA or BTS can be used as the RF source for the DAS. Primarily used to modify, improve or extend coverage of a site. Primarily used in large buildings, stadiums, public spaces, airports, enterprise & outdoor environments with strict zoning, etc.

Small Cells Low-powered radio access points (less than 1 Watt) that improve indoor and outdoor coverage to increase capacity and offload traffic. Deployments to begin in 2013.

Femtocells Femtocells are small personal BTS providing service over a limited area (5K sq. ft) to a limited number of users (4~20). Primarily used in small office / home office or residential areas.

* Repeaters are not available in some markets or venues

Macro and oDAS Benefits

Macro and oDAS antennas can be mounted on towers or rooftops, or other strategic vantage points that will provide the best and most efficient coverage for all subscribers.

The antennas are designed to blend into the environment and architecture so that they will be virtually undetectable

Features

•Dedicated capacity and coverage solution

•Custom designed to meet the needs and requirements of the campus

•Designed specifically for each facility

•Low profile, compact, scalable unobtrusive solution

Wireless Coverage Campus-wide

•A DAS is a network of antennas that are placed throughout the facility and are connected with cabling or fiber to a hub

•The hub allows for multiple wireless service providers to connect radios that transmit at various frequencies

•Remote units are placed on each floor and are connected to antennas which serve the floor

•AT&T will install the system and operate as a neutral host that enables multiple wireless service providers to use the network at the same time

Topic: Evaluate Your Drivers

mailto:[email protected]


DAS in Higher Education

• What are the “traditional” responsibilities of Information

Technology professionals?

…… Extended to Wi-Fi

…… And now …

……… DAS!

• And what are the challenges when it comes to DAS?

…… What is DAS?….

…….. The complexity of an RF cellular network….

…………It requires cellular carriers engagement/approvals

………….. And ….

……………….Where is the funding!?!?

To evaluate your funding options you need to know well your

real DAS Drivers!!!

• First-responders need reliable 2-way radio coverage in all buildings, tunnels, basements, etc.

• Student and faculty cell phone coverage is a matter of convenience.

• E-911 cell phone coverage is a matter of safety.

• Parents want instant access to their kids.

• Demand for coverage in stadiums.

• The image/reputation/brand of the institution requires good cell phone coverage for voice and data services through the campus.

It is important to rank your drivers by priority.

By evaluating your key drivers and your key stockholders, you will be able to asses which funding models will work best for your ecosystem.

Funding models examples:

• High-Ed funded DAS with cellular carriers providing signal source

• Carrier funded DAS

• Neutral Host company funding the DAS

Beyond the DAS materials and installation costs you should always be cautious and understand the DAS hidden costs:

• Foot print of the equipment used

• Power consumption of the equipment used (and power efficiency)

• How does the signal source connect to the DAS?

– Complexity

– Space requirements.

• Amount of active elements that constitute the DAS solution

– The more active equipment, the more potential points of failure.

Tower Company Overview

A viable funding option for your campus

Tower companies have a vendor and carrier agnostic approach, and work

with you on your specific requirements.

• They own and operate a large amount of the macro cell towers in the US

for the carriers.

• Their model is to provide the funding for wireless infrastructure and lease

back to the carriers over a period of time.

• Tower companies are your “wireless agent”. They partner with you to

determine the best wireless solutions, and can pay for it as well.

• They understand each carrier’s requirements and model your solution to

them.

• LMR, Public Safety radio, WiFi and Cellular can be included in the terms.


Procurement Marketing Leasing & Legal Ops

Design Installation Reporting &

Billing Monitoring & Maintenance

• They manage the “cradle to grave” system requirements, selection,

deployment, upgrades and ongoing maintenance.

• There are several creative funding options available, depending on need

and scope.

• Many times the Tower Company will risk build the wireless system once

the 1st carrier has signed on. You don’t have to wait.

• They are your partner and together you craft the options that work for all

the parties.

• The Tower Company is Carrier, OEM and Integrator agnostic. They design

what is best for all, not what is best for some.

• The Tower company funds the system, providing flexible financing options

• Actively markets the property to wireless service providers, putting revenue in

the building owner’s pocket

• No other model rewards the building owner better.


Leveraging your assets and ROI

A viable funding option for your campus

• Many times a hybrid wireless solution is the best option. Utilizing your

assets can minimize costs and provide more attractive options.

• Depending on the situation, higher education has received a recurring

revenue stream from the Tower Companies.

• Upgrading existing infrastructure, such as fiber, is occasionally part of the

discussion and can be accommodated in some cases.

• Tower companies can enable your project even if you don’t have budget.

• They have long standing carrier lease relationships across the US.

• They help to ease carrier on-boarding and signal source acquisitions from

the carriers.


Applications on the DAS

• Some higher education entities are adding applications to their existing DAS

networks. Why not utilize the smart devices in and around the campus to:

• Push course curriculum to the students

• Shuttle bus and campus event schedules

• Faculty and staff communication

• Student safety and security

• Partnerships with nearby retail establishments

• Interoperability with local first responders

• Promote a sense of community on campus

• Enhance your overall wireless bandwidth

• Reduce land line devices

You can do more than just make cell phones work on your campus.
