Who is DAS Simplified
• 65 years of Electrical Construction history
• Over 200 Million Sq. Feet DAS Installed Nationally
• Only IBEW national DAS integratorOnly IBEW national DAS integrator
Why Distributed Antenna Systems
• Changes in Construction– LEED Certified & Low-E Glass
E C d b i i i t i ti• Energy Codes are becoming increasing restrictive–Tighter Envelopes/ Triple Pane Glazing
• Energy Efficient means RF Deficient
Why Distributed Antenna Systems
• Changes in Fire Code– International Fire Code (IFC):: 2009 or 2012
– National Fire Alarm and Signaling Code:: (NFPA 72) 2010 or 2013
B ildi C t ti d S f t C d (NFPA 5000) 2012– Building Construction and Safety Code:: (NFPA 5000) 2012
Market Projections
• In-building Wireless Market to grow from $4.05 Billion to $10.65 Billion by 2019 (MarketsandMarkets)
• The number of cellular M2M connections will grow at gto reach 489.9 million at the end of 2018. (Berg Insights)g )
2018 Market Projections
(Cisco® Visual Networking Index (VNI)• Mobile data traffic will reach the following milestones within
the next five years.– There will be over 10 billion mobile-connected devices by 2018, including
machine-to-machine (M2M) modules
– Traffic from wireless and mobile devices will exceed traffic from wired– Traffic from wireless and mobile devices will exceed traffic from wired devices
– 4G traffic will be more than half of the total mobile traffic
– The amount of mobile data traffic generated by tablets by 2018 will be 1.9 times higher than the total amount in 2013 .

1. Building Survey
• Perform an initial predictive site survey of the floor plans to l bl l fevaluate possible equipment locations, project specific
unique considerations and critical path issues.No shielded or fortified rooms (i e hospitals)– No shielded or fortified rooms (i.e., hospitals)
– RF Survey, if required
– IDF/Telco locations/
– Roof penetrations available
– Coverage antenna can be mounted in the ceiling
– Clear cable paths are available

2. Common Carrier Questions
• How do I make sure the wireless service providers will go on my building?
• If I provide a BDA for them, will they agree to go on my DAS?
• What is the carrier approval process?What is the carrier approval process?
• How long will the approval process take, from contract to on air?
• How much can the owner expect to pay for the carrier’s signal source?
• What type of backhaul connection will the carrier require?What type of backhaul connection will the carrier require?
• How much space and power is required for the carrier’s equipment?
2. Carrier Coordination
.
2. Carrier Coordination
• Work with cellular carrier companies to gain approval for rebroadcasting purposes. – Communication with carrier engineers is on-going for up to 2 years
– If you build it they may NOT come!!!
– Documents and supporting materials are created and later submitted to cellular carrier engineers for approvalto cellular carrier engineers for approval
3. Design
• The predictive site survey will drive a preliminary design and develop technology specific link budgets, initial antenna placements, possible cable pathways, and RF H t MHeat Maps.
• The preliminary design will be revised based on the l f h RF Thi d i ill b d f hresults of the RF survey. This design will be used for the
pre-construction survey.
• Environmental considerations
4. Pre-Construction Survey
• Perform a comprehensive walk through to validate cable routes, antenna locations, floor penetrations and active equipment locations.
• A thorough and complete design validation will ensure a smooth and efficient system installation.y
5. Final Design
• A revised design should be generated based on any changes to installation design as recommended by the installation team.
• The final design should be submitted to the installation team for final approval before any pp ysystem equipment sourcing begins.
6. Carrier Approval
• Once the final design is validated, what is the carrier approval ?process?
• How do I make sure the wireless service providers will go on my DAS?DAS?
• The carrier will want to know the following:• Will the DAS enhance their customer experience?
• Will the DAS have enough capacity to meet the needs in the building?
• How many Corporate Liable phones does the business have?
H t ill th DAS b th l d i it ?• How many customers will use the DAS, both employees and visitors?
• How much will it cost to join the DAS?
7. AHJ Approval
• What things need to be coordinated for the final acceptance test?– This varies greatly from region to region and AHJ to AHJ
• Set of Test radios– VHF/UHF challenges
– Radio Shop UL measurements
– On Site time with Fire Marshal
– Access to all critical areas from building owner
– Alarm demonstration
7. AHJ Approval
• How will the AHJ test the system for acceptance?– This varies greatly from AHJ to AHJ
– Walk the floor and randomly test a radio
– Witness alarm activation at the FACP
– Monitor donor site radio noise floor
8. Equipment Sourcing
• Following carrier and or AHJ approval, passive and active equipment should be sourced along with quality assured process to ensure components are in working order.
• Not just any equipment will do!!
• Beware 16-week lead times.
• Did you say NEMA rated required for an indoor application?
• Ship equipment to job site.
9. Installation
• Install all cables, antennas and active equipment based on the provided drawings while performing routine quality control checks. – Work with the installation team to provide training and
best practices.
10. Commissioning
• Once the system is installed per the design, send a certified ld fField Engineer for system commissioning.
• Each carrier and AHJ has different testing requirements and f di ioften disparate test equipment.
• The Field Engineer will verify RF and optical cable f ti i t tti d tperformance, optimize system settings and measure system
output levels as compared to the expected values.
11. System Acceptance
• Connect carrier provided signal and evaluate RF coverage f b l h lperformance. BDA balancing with macro signals to insure
that maximum system performance is achieved.
B ildi k l d hi f h DAS• Building owner takes control and ownership of the DAS.
• DAS is a highly dynamic network and needs ongoing support f f h t t h l i Thi i 't tfrom frequency changes to new technologies. This isn't a set it and forget it, make certain there is an ability to monitor and serviceand service.
