Continuously increasing Mobile TrafficGlobal mobile data traffic will increase around 10 times between 2014

and 2018 reported by CISCO.

Smartphone represented only 27% of total global handsets in use in 2013,

but represented 95% of total global handset traffic.

Globally , 45% of total mobile data traffic was offloaded onto the fixed

network through Wi-Fi or femto cell in 2013.

Accelerate fiber deployment for Mobile

FronthaulThe mobile network is moving from copper to optical and the bitrate will

be improved to 10G bps. DAS systems and data off-loading will be

increasing especially at the network concentration places such as the

stadium. Hence, simple and efficient I&M work solutions are required,

such as easy to control, data management and cloud solution.

100G deployment continue in MetroIn developed countries, 100G deployment shifting from Core to Metro

Network. It will be accelerated in 2015 and later. It also accelerates the

number of 10G ports required.Source :F&S 100G deployment in N.A

Small Cells expansionContinued growth of mobile data. It will be 1000-fold between 2014

and 2020. But RF capacity has its limits and is unable to keep up

with demand.

SNS Research , The HetNet Bible

(Small Cells and Carrier WiFi)

SNS Research

How to support these market demandLimitation of RF resources is driving “Small cell” and “Carrier WiFi (as

a offload)”. The Centralized-RAN architecture (centralizes the

processing of mobile RRH across cloud-based data centers using

CPRI) is quickly becoming the de facto approach to areas where high

antenna density is required, as it allows for the efficient coordination

of handoffs, easier, less expensive to install and maintain.

Challenge of Centralized RANCentralized(Cloud) RAN service will be deployed to reduce processing latency. Current

backhaul is not suitably designed and monitored. These latencies will make negative impact of

QoS and QoE for customers.

Slide Title

In the past, Network Operators had a border between mobile

fronthaul and backhaul. From our point of view, I&M solutions

were also separated, Wired customer and Wireless customer.

Now the mobile operators try to change their network to

become more flexible and efficient, to ensure profit with

increasing mobile traffic and keeping QoS.

Looking forward to 5G networks, to make efficient network

with high QoS a new enhanced network will be required. The

border of Wired/Wireless network should be removed for

these changes.

Market changes and strategy – RF segment.


Slide Title

Expanding RF spectrum

Down to 800MHz, and next to 700MHz.

Up to 3.6 GHz, 5.6 GHz possibly, then 5G and millimetre wave.

Interference management becomes a key issue:

• Re-using many old frequency bands, with very crowded spectrum.

• LTE is primary standard, but OFDMA is not resistant to RF interference.


Slide Title

RF over CPRI

Removes long feeders, e.g. up the tower or building roof.

Small jumper cables still used from RRH to antenna.


Slide Title

Changing form factor, move to small cells.

Lower cost, small size, and higher frequency.

Drive to integrated RF/antenna.

5G and Massive MIMO drive to highly integrated RF front end with

active antenna.


Slide Title

Impacts to installation business

Mobile network evolution may change installation measurements.Currently, some operators are planning and rolling out new C-RAN system, includes CPRI/OTDR solution,

time management protocols and CPRI over RF. For the installation measurements the requirements are still

evolving.

Alternative technology may dominate the marketThe market change will be driven by “Copper to Optical” and “small/Micro cell/DAS network deployment”.

On the other hand, there are other technical challenges also considered in this market. There are G.Fast

and pico-cell systems. This technology is based on existing copper based infrastructure, such as xDSL and

in-door Ethernet.

expansion in metro area. 400G trial has started but it will start deployment

after getting cost benefit over 100G

> NEMs are thinking their customer’s concerns are reduction of investment.

> flexible bandwidth expansion ( Price/bandwidth is going down)

> Power consumption , space

> Integration both layers and network management

> Prepare L2 function and IP client for OTN mapping in their

lineup and then reduce Edge Routers

Redefining network Operator developing 5G network elements are making use of SDN and

NFV benefits such as operational efficiencies and service agility.

These benefits are best realized when the management layer has access to

the network intelligence to ensure that data traffic is routed as efficiently

and dynamically as possible.
