• Import and size floor plans• Add RF signal sources• Add DAS equipment and materials

– Certification Level 2: Propagation, Data Collection, Optimization

• Create “Walls” onto floor plans• Modify and adjust propagation characteristics• Create Predictive Analysis (2D and 3D)

Design Tools• iBwave (Continued)

– Certification Level 3: MIMO, Complex Venues, Capacity Planning

• Stadium environments• MIMO and WiFi offloading• Capacity considerations for data throughput

• Link Budget• “Dixie Cup”

– Preliminary approach only

Design Process• Initial Setup is Critical

– Scaling of Floor Plans– Reference Point – RF Signal Sources

• Channel Loading• RSSI vs. RSRP vs. RSCP

– Wall Type, Composition and Placement

– Coverage Requirements

Creating the Design• Neatness Counts!!

– Design doc installer’s instruction manual• Where antennas are installed• Interconnection diagrams

– Install manual as-built documentation• Used for maintenance, repair and upgrades

• Generate Bill of Materials– S/W auto-calculates % for waste– Per system, per building, per floor

• Database of Parts

Incorporate Survey Data

• Wall Types– Concrete Block, Drywall, Cubical

• Cable Pathways – Vertical, Horizontal– DAS Requirements

• Critical Areas– CEO’s office– Meeting Rooms

Survey vs. Predictive

• Import Survey Results into iBwave– Overlay onto Floor Plans

Carrier Coordination - WhyThe Carriers must always be involved!• DAS Solutions Rebroadcast Licensed & Regulated Spectrum• Carriers own their Spectrum (Licensed from the FCC)• Carriers must Approve the Design to Ensure their Participation• Carriers Issue Rebroadcast Agreements /Letter of Authorizations

If the Carriers are not Involved• Right & Authority to shutdown the DAS & keep it off• DAS Owner left with a costly and non-functional system• There is usually no recourse; a system redesign resolving deficiencies

and meeting Carrier approval must be performed, or remain off air

Carrier Coordination – Activities• Submit Design, BoM, Link Budgets & Predictive Analysis

for Technical Approval• Follow up with Carrier on Approval Status• Modify Design or Provide Clarification as Required• Provide Client/Venue Information for Legal Agreements• Follow up to Ensure Approval Process Moves Forward• Coordinate Signal Source & DAS Activation Activities• Provide As-Built Documentation upon Project Completion

Testing and Verification• Component & Cable Testing Return loss, DTF, PIM Optical loss, Reflections Antenna Testing

• DAS Equipment Configuration & Testing• Continuous Wave/RF Testing• Signal Source Activation• Optimization and Fine Tuning Power, UL/DL, Antenna Direction

• System Verification Survey & Verify Performance Metrics
