3. The current 3G roll-out has been insufficiently coordinated in order to deliver the
promise of quality “Internet for All”
The overall roll-out of 7,300 3G across the Philippines is currently taking
place
 Approximately 3,000 sites are due by May 2015
The roll-out of the required transmission bandwidth is scheduled and
planned to complete end November 2015
The current roll-out appears to have several issues;
 Site delivery appears to be random and there appears to be no
effective radio network planning, implementation and optimization
program in place
 Transmission and RAN equipment delivery appear to lack effective
coordination
 Commissioning and optimization appear to be sub-standard on a
site level
 Previous lack of cluster based implementation and optimization
appear to have led to poor quality and performance degradation
The drive tests conducted by Detecon lead suggest that :
 There is a strong signal with poor performance (dropped calls, low
throughput, …)
 High levels of interference (no dominant cell, overshooting, poor
radio layer coordination)
Summary – Problem Statement Scattered 3G Roll-Out
Core
Current vs. needed
Transmission lagging
behind
3G Site

4. Carrying out the roll-out as planned today, would result in a terrible
customer experience:
 Unacceptable level of call setup failure
 Poor voice quality
 High amount of dropped calls
 Low throughput
 Long page loading times (Facebook, Instagram, …)
 Jerky YouTube videos
 408 Request Timeout errors
 Failure to establish data session
The current approach does not enable maximum revenue generation
capabilities:
 Utilized cell capacity will not be 100%
 New sites could degrade the existing operational networks
(2G/3G/LTE)
 Customer expectations will not be fulfilled in line with marketing
campaigns
 Failure to deliver expected data speeds could result in in customer
churn
 Under utilized bandwidths and overall invested technology costs
will deliver less than optimal financial returns
Summary – Consequences of Current Roll-out
Non-optimized sites may downgrade
the customer experience
The previous strategy has now created network performance lower than that of the
operators major competitor

Major Issue 1: The current roll-out in Metro Manila appears to lack overall coordination
so that NodeB and transmission installations are scattered around the Metro Area.

Patched Optimization (or lack thereof)
The Metro Manila 3G deployment was performed in an
unplanned manner, which lead to:
 Patchy 3G coverage creating limited technology continuity,
reduced performance and a poor user experience
 Ad-hoc and inefficient site level optimization
There was also a lack of standard processes to guarantee:
 The performance of newly integrated sites
 That there is no impact on existing network KPIs and
KQIs
As the investigations only covered Metro Manila to date the
same issues could be replicated with the Ericsson and Huawei
rollouts (under investigation)
Additionally the transmission roll-out is loosely coordinated with
the 3G site deployment which can lead to congestion over the
last mile and possibly in the aggregation layer
– 6 –

7. Major Issue 2: First indications point towards high levels of interference, which
results in bad quality, leading to reduced bandwidth availability
 Initial drive test results lead to the strong belief that the
network has a lot of “leashed or locked” capacity and poor
voice and data performance are mainly due to interference
and other correlated technical issues,
a) The root cause and geographical extension of this issue
is being analyzed and will be confirmed by Detecon
(target within 2-3 weeks)
b) Pilot Pollution interference means that there are too
many signals received at specific points of the network
(so far only identified in MM) and that part of these
signals are acting as a polluter rather than a supporter
 As UMTS and EDGE are constrained by interference, pilot
pollution will:
 Lower the volume of voice calls during peak hours,
even though there is physical capacity to handler
further traffic
 Prevent high data throughput service in many locations
of the network, outside busy hours
 Limited or no access to data services during the busy
hour

B) Pilot Pollution
 Strong signals from

Metro Manila Roll-out
LEGEND
EXISTING SITE
TURBO roll-out
 Agree priority clusters in key areas i.e. Makati, EDSA, Taguig
and Ortigas, major highways, malls …
 Optimization shall be seamless, so Cluster should be
neighboring in order to optimize the borders as the 3G
network grows to the same level as inside a Cluster
 The optimal sequence
of Clusters would be
such that the areas form
a spiral
 Specific attention must be paid to RNC borders and BSC
borders, with specific methodology
 Then reach the vendor borders at the same time from the 2
sides, to ensure both resources are deployed to solve the
specific technical issues of inter vendor zones

Cluster
Transmission roll-out will closely follow the 3G site Cluster roll-
out
 FOC rings span areas greater than the individual Cluster
 Bandwidth from the sites is only part of the end-to-end
bandwidth requirement to be taken into account
Transmission planning has to plan/decide:
 Technology to use: FOC, µWave, copper
 End-to-end needs: which rings are affected, where will
additional bandwidth be needed
 Best use of available resources
Additionally, certain on-going activities affect Transmission:
 VDSL (with >20Mbps/copper pair) as a technology
 µW links can be used for rapid deployment. This could lead
a delay in reaching a full FOC network.
 Current vendors planned for a phase-out (can) get an
extension (ECI, Aviat) due to rapid delivery and/or
deployment
