Equipment
Considerations

Campus Specific
• Needed to support all of the waveforms and
technologies as listed (VHF, UHF, 700(LTE), CELL,
PCS, AWS, WiMax )
• Required both High Power Outdoor and Low/Medium
Power Indoor modules
• Minimize DAS Footprint (Head End and Remote
Space Restrictions)
• Support Build Requirements
– Remote BTS
– Centralized Head End
– Multiple Coverage Locations

WSP Desires & Considerations
• Minimize the number of Deployed Technologies
• Conserve OSP Fiber
• Separate Paths OR Partitioned Paths

Selecting the
Technology
No Single Technology Will Do It All !

Selecting the
Technology
Two Approaches Emerged
1.
Layer 1 = Outdoor
Layer 2 = Indoor

Layer 1 = WSP’s
Layer 2 = PS
Our Recommendation
A for WSP’s and E for PS

The Issues


RISK
• Existing DAS is no longer supported
• Spares are not available
• No Technical or Repair Services are available
This is a disaster just waiting to happen!
Can’t support Growth
• Wasn’t able to support entire initial DAS
Deployment
• No power to support additional channels and
capacity needs
• Doesn’t support 4G Technology
System is under powered in existing
configuration!
15
Key Considerations
•
•
•
•
Scalability
The new equipment needed to be able to support (1) ALL
currently deployed technologies, spectrums and channel
counts, (2) channel/spectrum growth to support capacity
needs and (3) addition of future 4G Technologies
Fiber Count
We looked for technologies that would not exceed the
current fiber availability between the Head End Compound
and the Remote Head End.
Cabling and Link Budget
To avoid the high cost of conduit, we looked for
technologies that would be able to use the existing
“grandfathered” cabling structure while improving the
existing Link Budgets.
Schedule
Speed is of the essence in eliminating the risk of
catastrophic system failure.
16
A 2 Phased Approach
PHASE I
Rapid deployment of an equipment change-out for the
existing services.
 Eliminate the Risk of Equipment Failure
 Improve the existing Link Budgets / System
Performance
 Addition of Capacity
 Should be handled as a maintenance/repair issue since
it is equipment only – no cabling.
PHASE II
Addition of Equipment and Infrastructure to support 4G
 Process will require “Full Scale” Design, Engineering,
Review, Permitting, Deployment, Optimization & ATP
Services
 Will require additional cabling/conduit layer(s) and
Antennas

E911 &
LTE MIMO
Planning


Enhanced Positioning
• 911 Mandates assessed at the County Level
• We propose DAS based technology using Co-Pilot Beacons for
CDMA systems and LMU’s for GSM systems to facilitate location
accuracy to the building of call origin.
LTE MIMO
• VzW is planning the first launch of a 4G LTE Network in the US;
this technology embraces a MIMO feature.
• MIMO requires twice the passive infrastructure of SISO /
traditional DAS deployments.
• MIMO throughput benefit is not known as a function of IB
Morphology Types or Antenna configurations.
• VzW LTE MIMO deployments in the 700 MHz band require
special/proprietary survey techniques before they can be
justified.

Stay Informed
• Know what’s coming from the WSP’s
• Know what the DAS Manufacturers are offering
today AND tomorrow
Understand the Project Needs
• How to take advantage of what the Venue has to
offer
• How to avoid the sensitive or restrictive Venue
