Nokia Siemens Networks frees spectrum, increases data capacity on #CDMA
EV-DO Advanced software helps operators meet surging demand for mobile broadband 
subscribers globally can now enjoy a vastly improved data experience and faster 
speeds, even in high density areas. With EV-DO Advanced*, Nokia Siemens 
Networks introduces a set of features that enable more efficient use of network 
resources. These features increase data capacity by up to 40% in loaded cells 
thereby helping operators economically manage greater data traffic volumes, 
without the need for hardware investment, via a straightforward software 
“We are fully focused on technologies that enable a superior mobile broadband 
experience, and EV-DO Advanced is one such development. It is a major driver of 
CDMA evolution and adding this to our portfolio reflects our strong commitment 
to the technology standard,” said Scott Mottonen, head of the CDMA/LTE business 
line, Nokia Siemens Networks. “By dynamically adding network capacity where and 
when it is needed through an incremental, selective and cost-effective upgrade, 
EV-DO Advanced addresses growing demand for data.”  
Nokia Siemens Networks’ EV-DO Advanced software comprises a number of 
capabilities** that increase network capacity, deliver higher data rates and 
prioritize and allocate bandwidth better to improve overall network efficiency. 
In addition, these features improve mobile device performance and extend 
battery life. This announcement follows the company’s previously launched 1X 
Advanced feature 
-siemens-networks-triples-cdma-base-station-capacity), both of which strengthen 
its portfolio and are further evidence of its commitment to the CDMA roadmap. 
Nokia Siemens Networks’ EV-DO Advanced software is commercially available and 
is currently being rolled out by a leading operator. In addition to the 
software, Nokia Siemens Networks also offers global expertise and a complete 
portfolio of services including consultancy, design and planning, systems 
integration, deployment, optimization, maintenance and managed services for 
CDMA networks.

* EV-DO Advanced is a CDMA2000 mobile technology standard that enables more 
efficient use of network resources.  
** Nokia Siemens Networks’ EV-DO Advanced software encompasses a number of 
features that increase network capacity. Those implemented include: 
•    Network Load Balancing (NLB) reassigns mobile devices from heavily-loaded 
sectors to lightly-loaded sectors, to increase network capacity, reduce 
backhaul bottlenecks and improve data rates. 
•    Smart Carrier Management maximizes data throughput and overall network 
capacity by assigning one or more carriers to a device (within the same cell or 
from an adjacent cell) if they are less loaded or offer better coverage. 
•    Enhanced Connection Management optimizes device connections to the network 
depending on the type of application being used to improve signaling capacity 
and reduce latency. It includes new features that will enhance device 
performance and data speeds and extend battery life. 
Other EV-DO Advanced features include:
•    Adaptive Frequency Reuse ensures seamless coverage by reducing the 
interference in a capacity-constrained cell so the primary carrier frequency 
operates optimally. 
•    Distributed Network Scheduler prioritizes and allocates bandwidth to 
multiple users at a network level, to maximize overall network efficiency.
•    With Single Carrier Multilink, two carriers using the same frequency can 
serve a dual-antenna mobile device from different cells/sectors. The user 
device can thus achieve the benefits of a multicarrier network, even if the 
user moves to a single carrier network.  
The following EV-DO Advanced features are embedded in the device, not in the 
•    Enhanced Equalizers take advantage of uneven loading traffic to 
significantly increase cell-edge data throughput.
•    With Mobile Transmit Diversity (MTD), the mobile device uses an additional 
antenna to significantly increase reverse link sector capacity and improve user 
data rates at the cell edge.
