Cellular Wireless Challenges in the Enterprise


It’s Still About Coverage in the Enterprise

• Rapid carrier network evolution leaves gaps in coverage; service indoor often not guaranteed

• We haven’t overcome the insulation of the indoor from outdoor

• Construction• Signal Dominance

• Enterprises typically plan on 100-150 square feet per person

•Average employee uses <100 MB data/day


Green Initiatives are Good for Energy Efficiency – Not so Good for RF Efficiency

• Construction & type of building has a great impact on wireless system performance & ease of installation

• Energy efficient buildings shield cell tower signals.

• 2.8B square feet of LEED-certified building space• ~45% of new non-residential construction will be

‘green’ this year


What’s The Answer?**it depends


Enterprise Wireless Requirements

1. Coverage everywhereA. In most enterprises user density is low, therefore capacity is not the issueB. Data usage is primarily achieved via WiFi, not cellular data networks

2. Support of one or more wireless operators, to accommodate not only employees/staff, but in some instances “roaming” visitors.

3. Support of one or more wireless frequencies (700, 850, 1900, AWS)

4. Minimal disruption to operations during system installation.

5. A system which is easily upgraded to handle future coverage and capacity requirements.

6. Mitigation of interference issues between mobile devices and other equipment (healthcare, robotics, etc.)

7. Aesthetically unobtrusive (invisible)

8. No safety hazards to the staff

• Repeater– Brings in RF from the outdoor macro cellular network– Low cost– Not dedicated capacity; variable performance throughout area

• Distributed Radios– Small radios called picocells and femtocells (based on power level)– Do not rely on the macro network for switching and hand-offs– Evolving technology often used for ‘Hotspot’ solutions for 1 or few “services”

• Passive Distributed Antenna Systems (DAS)– RF is distributed over coax cables to antennas throughout a building or area– Low performance solution as coax cable losses lower power & signal quality over

distance; performance is not uniformly reliable– Requires an RF source to feed the system

• Active Distributed Antenna Systems (DAS)– Fiber-optic based RF distribution system– System converts and amplifies signals throughout an area; amplifiers close to the user

for optimal network performance– High and low power solutions available for medium-sized buildings to large macro

networks– Requires an RF source to feed the system

There are Many Coverage & Capacity Tools


Low power amplifiers connected by cabling & distributed to deliver cellular (licensed-band) services:

• Connected to the cellular network

• Centralized backhaul connection to service provider (central office)

• 2G/3G/4G service agnostic

• Distributed by fiber, coax or Ethernet throughout local area

What are Distributed Antenna Systems and Where is DAS Deployed?

To improve wireless coverage and capacity in areas where cell towers can’t be installed or adequately provide service:

• Malls, hotels, casinos, arenas, stadiums, hospitals

• Campuses & public spaces

• Urban or suburban areas

• Tunnels, coastlines, canyons

• High-rise, MDU, Enterprise


Enterprise DAS


DAS is a Cost-Effective & Flexible Solution for Wireless Coverage and Capacity

• Flexible and scalable solution to accommodate single or multiple operators and frequencies

• Easy to design

• Active DAS is similar to Wi-Fi, easy to install

• Seamless interaction with the macro network

• Pay as you go, minimize up front investment

• Equipment may be centralized, keeping maintenance costs low

• Simple RF management – easy to add coverage

• Longevity of investment through scalability – capacity added when needed Main Hub

Things to Consider


Key Questions to “Right-Size” the Solution

• What’s the issue: coverage, capacity, or both?

• How many wireless users do you have (employees and guests)?

• Is wireless data supported via WiFi, cellular data, or both?― Today LTE is a data-only service

• Does one wireless carrier dominate usage in the facility?

• Is support for multiple operators necessary?

Facility and Installation Considerations – Potential Cost Impacts• Type of environment - Open layout, dense, mixed use

• Building’s construction materials (sheetrock, metal, concrete, etc.)

• RF design goals (required strength of signal)

• What type of cable infrastructure is installed and/or will be required?• Is there dark fiber available?

• Are there any special installation requirements? • Is conduit required?

– ~50% labor premium– How much conduit; Required in just the horizontals or everywhere?– How large is the conduit; how many fibers; how long are the runs?

• Building-code requirement or environmental need based on facility type

• Are there any fire code requirements?

• Working hours, access arrangements


Special Requirements

Hospitals• Tenting, union and/or incumbent installer, conduit, core drilling, work hour

restrictions, validation of drawings (lead-lined walls), proper definition of coverage requirements (e.g. Operating Rooms, boiler rooms, etc.), RF management plan.

Campus• Union and/or incumbent installer, validation of facility drawings and fiber map,

conduit, work hour restrictions, core drilling, high lift

Manufacturing• Union labor, conduit, work hour restriction, high lift

Airport• Union labor, security clearance, conduit, work hour restriction, high lift, RF

management plan.

Hospitality• Work hour restrictions, historic architecture, union labor (regional)

Corporate Office• Union labor, conduit, work hour restriction

Is “DC to Daylight” Necessary in the Enterprise?

AT&T Verizon Sprint T-Mobile

700MHz Data Data - Data

850MHz Voice Voice - -

1900MHz Data Voice Voice/Data Voice

AWS Data Data - Data

A solution which supports 700MHz, 850Mhz, 1900MHz and AWS frequencies can deliver 2G/3G/4G coverage and capacity for all 4 major U.S. wireless operators


What About Using Existing WLAN for DAS?

Not recommended because:

• Different technologies – different antenna footprint― Wi-Fi has 6-8x more access points than a typical

active DAS

• Unknown performance of installed copper plant

• The cost of the additional cable is negligible

• There’s no cost-efficient and simple solution available today


Should Cellular & Public Safety Be On The Same System?

Reasons to Combine

• Very similar RF penetration challenges

• “Always on” service expectation; cellular nearing “mission critical”

• Reduce cost by using common infrastructure and materials

Reasons to Differentiate

• Ownership & maintenance responsibility may be different

• RF stability differences

• Single point of failure

• Some jurisdictions mandate separation of systems (150+)

• Traffic prioritization (>40k calls daily)

• RF design plan may be unique• Different location priorities (stairwells

versus board rooms)• Different capacity loads demand different

amounts of amplifiers


Who Pays?

25


Common Business Models

Carrier Pays (traditional model)

• Carrier covers cost of all equipment, cabling and installation

• Customer “lock-in”, through long term contract

• Increase in customer satisfaction

Neutral Host

• Bear the burden of CAPEX and project organization

• Remove all performance risk from the building owner

• Focused ownership of the wireless assets to add value throughout the life of the project

• Recurring revenue through “lease” of the system to operator(s)

Enterprise pays

(emerging model)

• Enterprise pays for all equipment, cabling and installation (carrier provides RF source)

• No long term commitment to any carrier

• Not operator ROI driven


Enterprise Funding Challenges

• Financing in a BYOD? Multiple devices per user for which WiFi and mobile services expected

• Carrier portability doesn’t support carrier-paid investments in buildings

• Carrier ROI models are getting tougher

• Neutral Hosts can’t make the numbers work in enterprises

At the end of the day, in most cases, it will be the responsibility of the enterprise to select and fund a solution
