Challenge

• Reliability issues on 5G service
• Falling back to 4G/LTE network
• Dropped-call and handover issues
• Lack of RF expertise

Solution

Analyzing RF spectrum over CPRI

• 5G NSA relies heavily on 4G/LTE
• 4G network must be free of interference and PIM issues
• Automated approach allows quick and simple health check

Results

• RF spectrum over CPRI doesn't have to be rocket science!
• Fixing RF issue on 4G uplink solved instability issues on 5G
• 90% time saved for RF frontline technicians
• QoE improved dramatically
