Site Overview
Call Center– 140,000 square feet– 500 SIMS in each outer User area– Unlimited data plans on devices– 100% of devices on single operator– (4) BC 4/13 RN-310’s per User area– (5) RN-310 - Training area in middle– Backhaul - 1 Gb port/100Mb CIR
User Area User Area
Test Strategy– Normal usage by employees– This site has never allowed devices on
Wi-Fi.– 10 hour workday – VoLTE & Video are used extensively

INDOOR PERFORMANCE RESULTS
AnalysisUsage is much higher than normally expected as 100% of devices are on same operatorSystem Scalability
RF link and Ethernet fronthaul capacity have plenty of headroomBackhaul capacity is the controlling factor for system scaling
Average Daily Backhaul Usage– Downlink: 125Gb (this is very large volume)– Uplink: 10Gb– Traffic Average: 50Mbps
Average RAB’s– 530,000 per day– ERAB Drop Rate 0.50%
CSSR and HO– Consistent 99% or better range
RF Link Capacity– Operating peaks don’t exceed 20-30%

E-RAN Offloaded 45% Users from Macro Network RRC Connected Users Average
– BC 4 RRC Connected Users Average dropped about 45% after E-RAN enabled
– BLUE = BC 4 (1700 Mhz)
• Note: BC 4 is preferred on macro
– RED = BC 13 (700 Mhz)

E-RAN Increased Average Data Rate on Macro Downlink Throughput
– BC 4 DL dropped about 16% after E-RAN enabled
– BLUE = BC 4 (1700 Mhz)
• Note: BC 4 is preferred on macro
– RED = BC 13 (700 Mhz)
Downlink Usage
– RRC Connected Users dropped by 45% but DL Throughput dropped by only 16%
– Conclusion: Less users consuming more bandwidth means better user experience

Situation
Enterprise hotspots vs. Freeway commuters Consider: use E-RAN to offload macro capacity Goal: defer macro upgrades by making smaller investments in E-RAN

Re-Thinking RF Planning
Optimize Capital Utilization– Macro and Indoor together
– Removal of Enterprise or Venue “hotspots” may be more cost effective
Budgeting Thoughts– Certain sites that are not complaining about service (Macro offload is benefit)
– Complaining enterprise sites that meet “investment threshold”
– Complaining sites that have their own budget available
