DAS OPTIMIZATION

We at RAN Wireless have been continiously involved in optimising lot of DAS Venues.The prime objectives are to validate antenna connectivity, correct PSC/PCI at acceptable signal levels and once the site is on air based on live traffic to reach the KPI thresholds for Accessbility, Reliability and Data throughputs. DAS optimisation is a continious process and we have been a part of it.

  • Anomalies such as incorrect BCCH/PSC/PCI or antennas not transmitting must be escalated, and resolved immediately

CONNECTIVITY

EQUAL LEVELS

  • Additionally, DAS issues must be investigated where applicable – for example, if anomalies are seen where there is an apparent mismatch in coverage between carriers connected to the same antenna, the DAS settings/cabling should be checked

PROPAGATION VS ACTUAL

  • The above data shall be imported into iBwave to generate a report that will advise of the deviation from the original design propagation predictions 

GO LIVE

  • Upon successful completion and site verification during the RF Validation phase the site is unbarred to take on live traffic and later optimized on live traffic to reach KPI Threshold's.

RF VALIDATION (RFV)

KEY POINTS

  • Basic check of the DAS and Node B Equipmentfor any issues with cabling, antenna installation, and verify all componentsare alarm free

  • Verify the UL RSSI measurements at Node B level ahead of optimization for any interference.

  • Verify if all macro downtilts have been completed

  • Any issues identified must be communicated to the customer

  • Review and verify status of the parameterstrategy appropriate to the venue

  • Review of Hi-cap, Mid-cap parameters check-list

  • Idle mode strategy

  • Defining the inter-frequency (IFHO), intra-frequency and inter system HO strategy

  • Capacity offload/Layer management

  • Soft hand over (SHO) strategy

  • Strategy tointeract with the Macro

  • DAS Optimization - UL Sensitivity

  • PRACH Parameters

RFV Package

  • RFV Automated Reports from ACTIX

  • RFV Summary Report (Antenna Validation, pilot Polution Analysis & TX1/TX2 imbalance

  • Individual SC/PCI Plots for Scanner

  • Issues and Recommendations

RF OPTIMIZATION (RFO)

KEY POINTS

  • ACTIX Standard post-processing tools to produce reports and recommendations provided

  • Missing data points for each zone- Venue/Transient/Macro

  • Acuracy of data collection

  • Correct call modelsexecuted for respective UE

  • Any antennas not transmitting

  • Incorrect PSC or PCI or BCCH

  • Ingress from Macro-tilt change recommendations ?

  • Egress from DAS-changes to DAS antennas ?

  • DAS antennas overshooting/pilot pollution - changes to DAS antennas

  • SHO/HO functionality - missing Excessive neighbors

  • HO between DAS and Macro at all exits and vice versa

  • All changes to be approved by customerand ensure timely implememtation of all changes recommended.

 

CONDITIONAL ACCEPTANCE (RFO-CA)

  • Based on the walk testing KPI's

  • All isues should be resolved before acceptance

 

FINAL ACCEPTANCE (RFO-FA)

  • Based on the live traffic

  • Green KPI's for at least two high capcity events or 10 days

RFO CA Package

  • RFO CA Automated Reports from ACTIX

  • RFO Summary Report UMTS (RSCP/ECNO  for best server, Macro Ingress/Egress pilot)

  • RFO Summary Report LTE (RSRP/RSRQ for best server, Macro Ingress/Egress, TX1/TX2 sectors & Throughput Analysis)

  • Event Analysis

  • Issues and Recommendations

RFO FA Package

Final presentation showing the KPI's and the parameters changes done during event monitoring for at least two high capacity events
