5G Brings Ulta-Low Latency

– Measured One-Way Latency Below 1 ms (Round-Trip Below 2 ms)

• Round trip time <2 ms

• One way latency <1 ms

• Lowest latency is seen for

balanced TDD ratio of 50%

• Latency is largest for most

unbalance ratios of 10%

and 90%

5G Brings Major Improvement in Energy Efficiency

• Network level power

savings -50% at the typical

operation point of 10..20%

network utilization (over

24h period and whole

network)

• Idle base station power

Nokia Leader in 5G Standardization in 3GPP

• Most active working

groups in early phase of

5G are SA (service

requirements and

architecture) and RAN1
