NOKIA SIEMENS NETWORKS IMPROVES VOICE QUALITY FOR PLDT IN MANILA

     (The following press release from Nokia Siemens Networks was received by

Press Release
Manila, Philippines – November 28, 2012 
Smart Communications offers high-definition mobile voice in Manila
Nokia Siemens Networks enables crystal clear voice quality 
Smart Communication’s customers in Mega Manila, including the Bulacan and Rizal 
provinces, will soon enjoy unmatched mobile voice quality. The company, a 
wholly-owned subsidiary of the Philippine Long Distance Telephone Company 
(PLDT), has deployed Nokia Siemens Networks’ Wide Band Adaptive Multi-Rate 
(WB-AMR)* 
(http://www.nokiasiemensnetworks.com/portfolio/products/mobile-broadband/gsm/mob
ile-hd-voice-a-windfall-gain-in-user-experience) functionality which enables it 
to offer high-definition (HD) voice services to subscribers. Pilot 
implementations of this new feature have already been completed in Makati, 
Taguig and Rizal. 
Nokia Siemens Networks is deploying the WB-AMR software feature in Smart 
Communications’ 3G network, and will do so later in its 2G network. The upgrade 
process is simplified by requiring only software updates for the network, and 
results in subscribers of Smart Communications benefiting from improved voice 
call quality. 
The upgrade can be compared to the difference between AM and FM radio. 
High-definition voice makes it easier for callers to distinguish commonly 
misunderstood sounds such as “s” from “f”, “m” from “n”, and “p” from “t”. 
“In HD voice-enabled areas, callers with HD voice-capable handsets running on 
3G will be able to hear the difference instantly,” said Rolando Peña, head of 
technology at PLDT. “Nokia Siemens Networks’ WB-AMR functionality lets us 
deliver significantly superior voice quality. This reaffirms our commitment to 
implementing innovative services aimed at providing the best communications 
experience to our customers in the Philippines”.  
“This particular engagement with Smart Communications further strengthens Nokia 
Siemens Networks’ resolve to provide an innovative edge to its customers”, said 
Markku Nieminen, head of Smart Communications customer team at Nokia Siemens 
Networks. “Our WB-AMR technology, tailored to ensure an unprecedented 
communications experience, marks another step forward in our vision to create 
smarter networks for the future”.  
Smart Communications recently launched its Long Term Evolution (LTE) 
(http://www.nokiasiemensnetworks.com/portfolio/products/mobile-broadband/long-te
rm-evolution-lte) mobile broadband network supplied by Nokia Siemens Networks. 
Using the 2100 MHz frequency, the LTE radio access is based on Nokia Siemens 
Networks’ Single Radio Access Network** (RAN) 
(http://www.nokiasiemensnetworks.com/portfolio/products/mobile-broadband/single-ran-advanced/flexi-multiradio-base-station) and takes full advantage of the 
hardware concurrently used on that frequency for HSPA. The LTE throughput 
speeds are faster than in the 3G HSPA networks and latency is improved 
considerably, bringing top-of-class Internet access and rich communication 
experience to mobile subscribers. This is complemented with the simultaneous 
deployment of Virtual Antenna Mapping (VAM) in the 3G layer, a unique feature 
offered only by Nokia Siemens Networks. It enables doubling transmit signals to 
maximize the usage of multiple power amplifiers, thus further enhancing 3G 
coverage and throughput performance. 
In addition to providing WB-AMR, LTE and VAM, Nokia Siemens Networks is also 
supplying its NetAct 
(http://www.nokiasiemensnetworks.com/portfolio/products/operations-support-syste
ms/netact) network management system for consolidated and effective monitoring, 
management and optimization of Smart Communications’ network across all radio 
technologies. Nokia Siemens Networks’ Intelligent Self Organizing Networks*** 
(iSON) 
(http://www.nokiasiemensnetworks.com/portfolio/solutions/self-organizing-network
s) capability will be used for increasing automation and speeding up the 
rollout as well as optimizing Smart Communications’ LTE network.

Notes:
* Wideband Adaptive Multi-Rate (AMR) technology uses speech compression 
techniques to enhance audio bandwidth and provide a highly improved sound 
quality. HD Voice offers a significant improvement in the audio quality of 
voice calls. The reason for this is similar to a transition from an AM radio 
receiver to a near CD-quality sound. This is done by using new audio codec 
technology that allows transmission of a much wider speech audio bandwidth 
usage of 50-7000 Hz compared to the current bandwidth of basic service 
(300-3400 Hz). It transmits frequencies used in voice calls clearer than before 
and eliminates background noise to a large extent. As a result, the sound is 
much clearer, including a feeling of presence and transparency, providing a new 
level of user experience in voice service. 
** Nokia Siemens Networks’ Single RAN including the Flexi Multiradio Base 
Station provides a future-proof, easy and cost-efficient path to LTE in both 
FDD and TDD spectrum bands via a simple software upgrade. Besides the Single 
RAN that supports GSM, 3G, FDD-LTE and TD-LTE, the company’s LTE telecom 
infrastructure offering also features the Evolved Packet Core, including Flexi 
NS (Network Server) and Flexi NG (Network Gateway), transport solutions, 
network management system, Self Organizing Networks (SON), the award-winning 
Voice over LTE (VoLTE), provisioning and charging solutions and a range of 
professional services to plan, install, maintain and operate networks. For more

*** Nokia Siemens Networks’ industry-leading SON Suite is part of its Liquid 
Radio and is based on hybrid architecture with intelligence residing both in 
the distributed network elements and in the centralized NetAct Operations 
Support System (OSS). This ensures that all areas of SON i.e. 
self-configuration, self-optimization and self-healing are addressed 
efficiently in an unparalleled way with the highest level of automation and 
richest set of features commercially available for use today.  
At the core of SON Suite is the market leading multi-technology, multi-vendor 
NetAct network management system and Flexi Multiradio Base Station supported by 
core network solutions. The SON Suite bypasses time-consuming manual processes 
in network operations to improve operational efficiency. This is done through 
introduction of automatic network configuration for handover processes, 
self-healing for secure uninterrupted end-user services coupled with minimizing 
the need for drive tests. It also helps operators introduce new technologies 
and expand networks faster with the proven industry-leading SON Plug and Play 
feature for automated Base Station network integration that was launched in 
September 2009. Nokia Siemens Networks SON Suite provides operators with 
reliable and scalable automation features for fast time to quality.
