COPs Are An Integral Compilation of All DAS Components
In a structured journey toward a fully functional Distributed Antenna System (DAS), the Closeout Package (COP) is the fourth phase, finalizing a project consisting of meticulous planning, execution, and validation.
The initial three phases – Surveying and Engineering, Construction, and Commissioning and Integration – lay the groundwork for the DAS infrastructure and pave the way for the COP.
The COP is – at its core – a compilation of all deliverables amassed throughout the foundational phases and has two primary objectives:
Proof of Work: The COP is a testament to the work undertaken and the tests conducted in constructing the Distributed Antenna System (DAS).
Facilitating Troubleshooting and Maintenance Activities: During troubleshooting or maintenance tasks, the COP serves as a valuable guide. Organizing the data within it is crucial for efficiency. It should be structured to allow for the swift and easy retrieval of frequently accessed information.
Steps For A Successful DAS Closeout Process
When undertaking the COP process, it’s important to acknowledge its flexibility. While a structured approach is recommended, the process we discuss below can be undertaken in a different order, and flexibility allows for adaptability to project dynamics and evolving requirements.
A valuable tip to streamline the process is to collect and compile the closeout package incrementally throughout the project lifecycle. Rather than deferring this task until the project is complete, gathering and organizing the necessary information as you progress through the project proves more efficient and ensures the availability of essential documentation when needed.
Update Design with As-Built Information
Incorporate the as-built drawings and information into the design. As-built documentation reveals the final placements and configurations of DAS electronics, antennas, cable routing, and other components.
Compile All Design Deliverables
Consolidate all design deliverables into a single location to access DAS information easily. It’s advisable to incrementally gather and compile these data for the closeout package throughout the project rather than wait until completion.
Collect and Organize Test Results
Gather and arrange all test results in a centralized repository. This includes sweep and PIM test data for coaxial cables, OTDR and optical loss test data, and CW commissioning data illustrating calculated versus measured values. Centralizing these results facilitates efficient access and reference throughout the project lifecycle.
Contextual Map and Label at Head-End
Incorporating a contextual map and label at the head-end proves immensely beneficial, especially for extensive campus deployments. Similar to the ubiquitous maps found in malls, this “You Are Here” type map provides an overview of the entire DAS layout. We implemented this strategy during large stadium DAS roll-outs, where managing 20-30+ racks could become daunting. Such a map serves as a navigational aid, particularly in complex environments.
Frequently Used Information (FUI) Card for Maintenance & Troubleshooting
The FUI card, short for Frequently Used Information, streamlines maintenance and troubleshooting efforts. While 90% of the COP comprises test results and historical data, only 10% holds critical information crucial for rapid issue resolution. This includes access details for the head-end room, URLs, access credentials for data controllers, and the identification and locations of remotes. The FUI card centralizes this essential 10% for easy accessibility during critical situations.
Optional Practice: Posting Logical Diagrams
Another recommended – but optional – practice involves displaying logical diagrams at DAS head-ends. These diagrams offer a quick visual reference for understanding the entire DAS landscape. Additionally, leaving USB drives containing logical diagrams in PDF format for maintenance technicians ensures rapid access to vital information when needed. This practice enhances operational efficiency and aids in troubleshooting and maintenance tasks.
