5G Vision & Priorities (5G-PPP.EU)Field Trials 2018, Commercial Deployment 2020

Goals - in comparison with 4G

1000 X mobile data volume per region

1000 X number of connected devices (IoT)

100 X user data rate

Guaranteed user data rate > 50Mbit/s

5G driven by emerging technologies Software-defined networking (SDN)

Network functions virtualization (NFV)

Mobile edge computing (MEC)

Fixed mobile convergence (FMC)

C-RAN Bandwidth Challenges (CPRI)Pendulum Favours Ethernet After ~2020

Mac-Phy optimum split = Ethernet based C-RAN, evolved fronthaul, ideal backhaul

106.05.1.01 : Virtualization for Small Cells: Overview, June 2015

IEEE 802.1CM PAR - April 2015:5.4 Purpose: The purpose of this standard is to enable the transport of time sensitive fronthaul streams in Ethernet bridged networks.5.5 Need for the Project: A mobile operator's radio equipment and radio equipment controller are often separated and the connection between them has very stringent requirements. This fronthaul connection is not provided by a bridged network today. In an IEEE 802.1 bridged network potentially carrying other categories of traffic , specific configurations of various IEEE 802 standards (e.g. P802.1Qbu, P802.1Qbv, P802.3br) are needed to meet the requirements of the fronthaul streams. Therefore, the use and the configurations of functions defined in the IEEE 802 standards have to be specified by standard profiles for bridged fronthaul networks.

Note: Virtualisation of BBU, Numerically intensiveLacking standards for transmission until approx. 2020

Proposals

Centralize BBU / vCSGW (NGMN >50% OPEX saving)

Plan for physical BBUs in central office until approx. 2020, along with CPRI/OBSAI to RRHs

Transmission network which supports CPRI, a good investment for low latency/5G. Ethernet(TSN) model may improve scalability once standardized, then vBBUs may be practical

5G Why Wait?

2016 ADVA Optical Networking. All rights reserved. Confidential.20

Why Wait for 5G? 1. MNOs have requirements which need solving now

OPEX management Cell site simplification Improve scale and performance

2. 5G Aims and MNO challenges converge 5G is not just an air interface, it is a networking mindset

Support for legacy/diversity

C-RAN

FMC

NFV/SDN As with other telecommunications sectors

Openness, interoperable standards, avoid vendor lock-in

3. Many of the networking tools to support 5G are ready for demo/trial

Dont wait for the air interfaceMNOs and wholesale providers invest for tomorrow and benefit today!
