Spectrum’s & Technologies Public Safety WSP Spectrums & Technologies AT&T 700MHz – LTE Cell A – GSM & UMTS PCS C4, D – GSM & UMTS AWS Sprint 800/900MHz – iDEN/SMR PCS B – CDMA 2700MHz – WiMax T-Mobile PCS A – GSM Verizon Wireless Cell B – CDMA/1x-EvDo PCS E – 1xEvDo

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

INTERNATIONAL AIRPORT NEUTRAL HOST DAS UPGRADE PROJECT EXAMPLE INTERNATIONAL AIRPORT NEUTRAL HOST DAS UPGRADE PROJECT 14

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!

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.

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

The Existing Infrastructure 24 Strands of SM Fiber from the Compound to Terminal C 12 Strands of SM Fiber to each Remote 3 Sector Design Each Remote has 6 Coax Ports 4-Low and 2-High

Venue Considerations Include Public Safety, WiFi 802.11n in non-public space No Outdoor – high power Indicate if analog signal is going to ride on SM fiber Limited Head End and Remote Closet Space Very few IDF/Closets spaced far apart Airport Operates 24/7 UPS Power requirement (KVA load) including back-up batteries Cooling requirement at Head End Airport will own the system Verizon Wireless Confidential and Proprietary Information.

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. Verizon Wireless Confidential and Proprietary Information.

Scoring Results

Our Task 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 Elements What the TOTAL technology needs are for both the Venue and the WSP’s Provide an Objective Evaluation of the available DAS choices
