IEEE 5G Summit | Nov 2015

1980 – 1G 1990 – 2G 2000 – 3G 2010 - 4G 2020 – 5G

• Analog systems
• Large terminals
• Several systems
• Voice only
• Digital systems begin
• Smaller Phones
• Several systems
• Lower power

consumption

• Low data rate

services (SMS, email)

• Emergence of smart

phones

• Dominated by two

standards: UMTS and CDMA2000

• Data rates up to 42

Mbps

• Wide range of

services

• Widespread adoption
• f smartphones
• Dominated by

LTE/LTE-A standard developed by 3GPP

• Data rates 150+ Mbps
• Rich services
• Global 5G standard

developed by 3GPP

• Massive connectivity
• Data rates 1Gbps+

(fibre like speeds)

• Very fast service

Cellular Standards Evolution

Economy of Scale through standardization

5G will enable diverse services and use cases that cannot be fully addressed by 4G systems

• Mobile video and gaming
• Cloud computing and storage
• High speed connectivity
• 100+ Mbps avg. throughput
• 10+ Gbps peak throughput

Enhanced Mobile Broadband (eMBB)

• 106/km2 connection density
• Low cost/energy connectivity

Massive Machine Type Communications (mMTC)

• 99.999% service availability
• 1 – 10 ms latency

Ultra-Reliable, Low-Latency Communications (uMTC)

• Billions of connected devices
• Sensor networks
• IoT / M2M / D2D
• Tactile Internet
• Natural disaster relief
• E-Medicine and Health care

Why do we need 5G? Target Use Cases

> 10,000 Mb/s

(peak)

~ 1 ms > 500km/h

As much as possible

> 100,000

Avg ~25 Mb/s Peak 150 Mb/s Typically ~50 ms 10 ms for 2-way RAN Functional Up to 350km/h DL: 0.1 – 6.1 b/s/Hz UL: 0.1 – 4.3 b/s/Hz Typically ~2,000 Active users/km2

Seamless migration from 4G RAN to 5G RAN

Network Evolution Through SDN/NFV

Different Platforms of Today

• Internet traffic flows across different service

platforms

• Services operated on specialized Physical

and Control infrastructure Converged, Cloud based Platform for 5G

• Services that previously required

dedicated hardware are abstracted into software functions

• Services will be provisioned and

controlled on common infrastructure

• SDN/NFV will unify ALL SERVICES
