VPO Overview

VPO (Virtual Planning & Optimization) is a Process & Knowledge driven system.

Aims to perform Radio/Transmission Planning & Network Optimization from a

location that is remote to the Physical Project Location.

To split planning & optimization scope is into field and office work

� Field work (e.g. DT measurement collection, RF/TNP surveys) needs to be

done at project location.

� Office work (e.g. analysis of DT and OSS data, planning simulations and

database updating) can be done remotely, as long as results are delivered

in desired format.

Value Proposition

20

Cost effective especially for high cost areas (e.g.

Australia, Japan, USA).

Fast Delivery cycle Quick deployment of project (e.g.

few engineers needed physically at project location

only).

Ideal solution for high-risk or hard access areas.

Low fixed Cost regardless of the project location.

Flexible service packages to meet unique customer

needs.

Expertise known and guaranteed.

– e.g. expert can be in only ONE project location;

but with VPO, same expertise is available for

MULTIPLE projects.

Turnkey Case Study- Example

Assumptions :

To see cost impact of VPO, we look at typical RF/TNP turnkey project.

Location is a high cost area, e.g. Australia, Europe, USA etc. Duration 12 Months and 1000 Sites new rollout with specified KPI.

To simplify comparison, we will compare cost impact for manpower only.

Case study is simple example of how VPO can save cost.

Exact savings cannot be ascertained yet as VPO cost structure is still being worked out.

Typically, VPO charges by package and not man-month.

With higher volume and continuing increase in efficiency, VPO costs would typically go down.

VPO costs are actually not pure man-month but would also include center maintenance,

equipment, remote side equipment, liaison, etc.
