Benefits of 4.3-10 connector
7/16 Connector
Better PIM performance Easier and faster installation Smaller and lighter
4.3-10 Connector
allows more connectors in limited
space, ideal for multi-band
portfolio
improves network performance allows cost savings
4.3-10 Connector Migration is the Obvious Trend

Operators Many Operators asking for…
Others..
?
e.g.
Huawei/Nokia:
4T4R RU using
4.3-10
connector
e.g. Ericsson:
NG-Radio with
4.3-10 connector
e.g. Huawei:
switching to 4.3-10
connector
e.g. Kathrein/Andrew:
Using 4.3-10
connector
…..
e.g.
Rosenberg/Spinner/
HUBER+SUHNER/
Telegärtner:
Providing 4.3-10
connector & jumper

4.3-10 Taskforce For Minimizing Migration Risks
5
The Concerns Considered by Operators
source: the 4th Huawei global antenna & AAU summit
Elaborate a coordinated
migration proposal minimizing costs and risks
• Connector migration spread over many years
• Unmanageable mixed situation at sites
• Difficult network planning by too many
scenarios
• Higher TCO and installation cost by extra
jumpers
• Increased stock levels of similar devices with
different connectors
Activities and Objectives of Migration Project
6
Objectives
Activities
Prepare a proposal for a cost
efficient and coordinated
migration
Create an open industry
platform to exchange ideas &
concerns
Ultimately propose a common
migration strategy including
time plan
Avoid costly and time consuming
multiple replacement of site
components and exploding logistics
Deliver great customer experience
and bring operational efficiency
Facilitate multilateral cooperation of
operators and vendors

Item Month/Year Short activity description
Start of Project: M0 13.5.2016 • Kickoff
Milestone: M1
06/2016 • Workshops and conferences to define a proposal for a cost efficient and
coordinated migration from 7-16 to 4.3-10 RF connectors.
Milestone: M2 07/2016 • finalized common migration strategy proposal including time plan
Milestone: M3 09/2016
• Equipment vendors map out their strategies of when to change which products from 7-16 to 4.3-10;
• Operators issue clear migration strategies to be used in future RFQs and site upgrade plans
Milestone: M4.1 12/2016 • Regular meetings and workshops to exchange concerns & problems &
ideas during the 4.3-10 migration Milestone: M4.2 06/2017
Milestone: M4.3 12/2017
