Host Keynote Opening Remarks and Presentation

  • Objectives for the Workshop
  • Strategy, Challenges and Future Considerations for Remote Radio Heads at the Top of the Tower
  • Assessing 4G Deployment Plans (Existing and New Bands)
  • Consideration for Managing PIM and General Interference, Especially Considering Small Cells
  • Where do Carriers See PIM Verification Testing Going for Truly Distributed Antennas with a Transceiver Module on Each Radiating Element?
  • CPRI is Not a Defined Standard, so Each OEM has Their Own Protocol; How Do the Operators Anticipate Test Equipment Manufacturers Will Meet Their Needs in the Future, if They Do Not Have Access to this Protocol?
  • Small Cells Represent New Challenges in PIM Certification
  • What Plans Do the Operators Have (Or Wish For) for PIM Verification in Small Cells?

Active Antennas and Remote Radio Heads

  • Some operators and vendors are for open radio interface (ORI), it does not appear to be embraced by the OEMs. The interface between the RRH/Active Antenna and the BBU remains closely guarded by each OEM.

    • Is the notion of equipment with open radio interface (ORI) a practical goal?

    • Do we need to develop a standard for a secondary (possibly wireless) interface mechanism to achieve some of the goals for basic monitoring/control/alarms of active products?

  • What are current 3GPP recommendations for PIM testing?

  • Prognostics/Maintenance/Site Monitoring

    • Linking measureable statistics with reliability/MTBF predictions to aid operational alarm threshold setting

    • Linking empirical data with analysis

Committee Updates: Survey on Alarms and Open Radio Interface, Prognostics and Field Return Observations

  • Best practice for Field Acceptance Testing

  • Best practice for future Proofing, Configuration, Control and Sparing

  • Statistics of field failures and how to improve reliability

2:20 PM

Surge Suppression and Protection

  • Understanding of the Tower Top Environment

  • Considering Effects of Lightning and Electrical Storms

  • Is There a Need for the Creation of Cohesive Standards for the Proper Selection and Coordination of Lightning Protection Devices?
