2. The convergence of wireless and the Internet is
revolutionizing the way we live, work and play
New systems and applications are creating
opportunities and challenges at an unprecedented rate.

3. In Building Market Drivers
Outdoor networks are built out from tower perspective
Enterprise and consumer expects their phone to work everywhere-all the time!
80% of calls and data sessions are made from indoors
Public Venues!!!
New building codes make it harder for signals to penetrate
Shift in need from coverage to capacity
Data usage indoors high and ever - increasing

5. What is a DAS?
Distributed Antenna System

6. Carriers LIKE in-building systems
Why? – Because it’s their licensed spectrum
Shifting need from coverage to capacity
3G (UMTS) & 4G (LTE) require better RF signal for better user experience. The better the UE, the happier the customer.
Public Venue spaces- multi carrier/neutral host
Past – Carriers paid for the system
Today Too many systems
ROI is the driving factor

7. Why would a Building Owner Fund?
Enterprise may consider covering the cost burden of DAS for several reasons:
WSP will not fund DAS
Carriers more likely to contribute (plug in) if Enterprise
owns and maintains the infrastructure
Enterprise often wants:
More than one WSP to be supported
Control of which WSP to be supported
DAS to support services besides what WSP offer
Lease and Revenue Share Options

8. Regulatory Drivers – Public Safety Ordinances
9/11 highlighted importance of PS coverage
New mandates and ordinances in some regions are driving DAS installations
Municipalities and/or public safety agencies may require 1st responder indoor coverage
New building codes must be met prior to occupancy

9. Passive System of coaxial or radiating cable
Yagi and/or Dipole antenna to amplifier to couplers & splitters to indoor antennas with lighting protection and battery back-up are quite common.
Active System - Larger buildings or multi-spectrum systems require fiber to active electronics to mitigate the loss throughout the lengths of the runs. These are converted back to coax and run to the antennas. Customers can potentially leverage existing fiber to save hardware and install cost (dark fiber).

10. What? : How it Works - Passive DAS

11. Passive DAS Full/Wide band repeaters
These units are less costly and readily available, but not typically approved for use by Tier 1 Wireless Carriers. These units could possibly interfere with neighboring carrier signals if not designed and installed properly.
Wilson Electronics
Band specific repeaters
Repeater only broadcasts desired frequencies. Better potential to gain carrier approval and avoid interference with the RF environment if there’s not a high capacity need.

13. Cabling and Connections…..Wired for Wireless
Coax
Up until recently <100k sq./ft. are coax solutions
Passive Solution – pulled coax, terminating connectors, & antennas
Typically less costly with a faster install
More loss on horizontal runs instead of vertical when pulling coax
Single Carrier
Fiber
Generally > 100k sq./ft. – depends on the layout of the building
Active Solution – head-end equipment & remotes
Pulling & terminating fiber requires a certain skill-set & expensive tools (splicers & test kits)
Some buildings may have existing fiber which can mitigate overall cost
Needs to be commissioned by a knowledgeable/experienced integrator – preferably certified (Mobile Access, Ion B, CSI – TESSCO can assist with that)
Public Safety and Multi-Carrier Solutions are best deployed with fiber because the active component of fiber provides the optimum results for combining signals
In general – for smaller opportunities fiber can be over-kill, but it is the right application for larger buildings, public safety, multi-carrier solutions, and certain unique layouts.

14. Planning and Budgets….I need to do what? How much?
What items need to be taken into consideration?
Frequencies / Spectrum
Carrier Coordination
Budget
Design
Deployment
Testing

15. What Spectrum ? – Cellular and Public Safety
Types of Cellular spectrum Types of Public Safety spectrum
Cellular 850 MHz SMR
PCS 1900 MHz MHz
LTE 700 MHz (Long Term Evolution) 800 / 700 MHz Dual Band
AWS 1700 MHz UHF 406 MHz to 512 MHz
VHF 144 MHz to 174 MHz
Coverage solutions need to be carefully designed to fit the needs of each building. Priority areas versus non-essential spaces can be vital to maximizing the enhanced footprint and minimize cost.

16. Carrier Coordination Why do I have to coordinate?
Carriers own the frequency. They spent billions of dollars and want to protect it.
Carriers reserve the right via the FCC to shut down a system
You cannot disrupt their network
When do I have to notify Carriers?
You should always notify the carrier
Start this process earlier. It can take up to 6 months
When do Carriers really care?
Everywhere outside of residential use
What would you need to provide?
iBwave Heat Mapping Design (TESSCO provided)
Certifications (TESSCO Training available)
For large projects, Carriers may require a base station, sometimes they pay for it & sometimes they don’t
