DL - 4G Americas

conducted with the 4G mobile technology running on commercial hardware at Nokia Siemens
Networks’ Bengaluru R&D facility, marking an important milestone moving 2.3 GHz TD-LTE
closer to commercial availability. (Rel-8; October 2010)
Nokia Leading the Way with Better Voice Quality. Nokia is leading the way in support of the Adaptive
Multi-rate Wideband (AMR-WB) codec in mobile devices. This feature, when supported in the network
and mobile device, provides a high-definition, crystal-clear voice call experience to the end-user. AMR-
WB uses twice the sampling rate of its widely-used predecessor codec, the Adaptive Multi-rate (AMR)
codec. The AMR-WB codec also covers almost twice the frequency bandwidth as “classical” AMR. Voice
calls carried over the AMR-WB codec are characterized by very high audio quality which replicates being
in the same room as the person on the other end of the call. The end-user also experiences less
background noise and better voice intelligibility, making mobile voice calls more natural-sounding than
wireline calls.
3GPP Rel-5 introduced the AMR-WB codec that began to take root in commercial wireless operations in
2009. Support for the AMR-WB codec is present in the following Nokia mobile devices: 6720 Classic,
E52, E55, X6, 6700 Slide, E72, X5, E5, C3-01, X3-02, N8, E7, C6-01, and the C7. Nokia expects support
for this feature to grow in its 3G terminal portfolio.
A True Worldphone – Access to 3G Anywhere on the Globe
The ability to use a GSM mobile phone anywhere on the globe has been there for quite some time. In
many GSM devices today support for up to four GSM frequency bands, including 850, 900, 1800, and
1900 MHz is quite commonplace. Over the past three years the mobile phone industry has seen multiband
frequency support grow to the level whereby 2-3 UMTS-HSPA bands are supported on UMTS-
HSPA phone models. Nokia, during 2010, has taken the support for multi-band capability on UMTS-
HSPA to the next level. In September 2010 Nokia announced the N8 and E7, both of which support
UMTS-HSPA on five frequency bands -“penta-band HSPA capability.” This 3G band support is in addition
to the classical “quad-band” GSM/EDGE band support also present in these devices. The five UMTS-
HSPA frequency bands supported in the N8 and E7 include 850, 900, AWS (1700/2100 MHz), 1900 MHz,
and 2100 MHz. This level of 3G frequency band support allows these devices to be used in UMTS-HSPA
networks almost anywhere on the globe and covers all of the 3G frequency bands supported in the
Americas region.
Note: 3GPP Frequency Band Designations for the Frequency Bands supported in the N8 and E7 are as
follows: 850=Band 2, 900=Band 8, AWS (1700/2100)=Band 4, 1900=Band 2, and 2100=Band 1.
Openwave: The number of wireless devices is scheduled to reach six billion worldwide, with a growing
percentage of these devices providing a rich online experience. The great challenge for mobile operators
around the world is how they will manage the growth in data traffic on their networks. The escalating
number of devices, data subscriptions and rich apps requires agile, intelligent mobile networks if
communication service providers wish to deliver on the promise of always-on, real-time services.
Openwave Integra provides operators with a next-generation service mediation and policy management
solution designed to allow operators to effectively manage, monitor and monetize mobile traffic. Integra
orchestrates and mediates a set of mobile internet services that are driven by a rich policy-rules engine,
allowing each transaction to be processed based on factors that include user profile, device capabilities,
content and network type. As traffic increases, Integra can rapidly scale to deploy new mobile data
services across converging access networks and devices.
