The Experts are Saying

• The focus is shifting from deploying cellular
  network infrastructure in large public venues to
  the enterprise
• According to ABI Research, in-building wireless
  market revenue will double to 9B by 2020
• The market has become very focused on the
  enterprise Joe Madden, Mobile Experts

Cellular Wireless Challenges in the Enterprise
9
Its Still About Coverage in the Enterprise

• Rapid carrier network evolution leaves gaps in
  coverage service indoor often not guaranteed
• We havent overcome the insulation of the indoor
  from outdoor
• Construction
• Signal Dominance
• Enterprises typically plan on 100-150 square feet
  per person
• Average employee uses lt100 MB data/day

10
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

11
Whats The Answer?

• it depends

12
Enterprise Wireless Requirements

• Coverage everywhere
• In most enterprises user density is low,
  therefore capacity is not the issue
• Data usage is primarily achieved via WiFi, not
  cellular data networks
• Support of one or more wireless operators, to
  accommodate not only employees/staff, but in some
  instances roaming visitors.
• Support of one or more wireless frequencies (700,
  850, 1900, AWS)
• Minimal disruption to operations during system
  installation.
• A system which is easily upgraded to handle
  future coverage and capacity requirements.
• Mitigation of interference issues between mobile
  devices and other equipment (healthcare,
  robotics, etc.)
• Aesthetically unobtrusive (invisible)
• No safety hazards to the staff

13
There are Many Coverage Capacity Tools

• 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

14
What are Distributed Antenna Systems and Where is
DAS Deployed?

• 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

• To improve wireless coverage and capacity in
  areas where cell towers cant 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

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

• 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

Things to Consider
18
Key Questions to Right-Size the Solution

• Whats 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?

19
Facility and Installation Considerations
Potential Cost Impacts

• Type of environment - Open layout, dense, mixed
  use
• Buildings 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

20
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

In Search of the Holy Grail

• The Bridgekeepers Three Questions

22
Is DC to Daylight Necessary in the Enterprise?
ATT 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
23
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
• Theres no cost-efficient and simple solution
  available today

24
Should Cellular Public Safety Be On The Same
System?

• Reasons to Combine

• Reasons to Differentiate

• Very similar RF penetration challenges
• Always on service expectation cellular nearing
  mission critical
• Reduce cost by using common infrastructure and
  materials

• Ownership maintenance responsibility may be
  different
• RF stability differences
• Single point of failure
• Some jurisdictions mandate separation of systems
  (150)
• Traffic prioritization (gt40k calls daily)
• RF design plan may be unique
• Different location priorities (stairwells versus
  board rooms)
• Different capacity loads demand different amounts
  of amplifiers

25
Who Pays?
26
Common Business Models
27
Enterprise Funding Challenges

• Financing in a BYOD? Multiple devices per user
  for which WiFi and mobile services expected
• Carrier portability doesnt support carrier-paid
  investments in buildings
• Carrier ROI models are getting tougher
• Neutral Hosts cant 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
28
DAS Simplified
29
Enterprise DAS Can Be Easy!

1. Identify your real needs based on user population
   density(dont ask for what you dont need in the
   future)
2. Understand what support you need from the
   carriers involve them right away OR find a
   business partner who will do that for you
3. Understand what your barriers may be with your
   building construction, space and access during
   installation
