Nokia Siemens Networks introduced a set of EV-DO Advanced features for CDMA network operators that enable more efficient use of network resources. The company said new EV-DO Advanced software can 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.
“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.
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 infrastructure:
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.
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. http://www.nokiasiemensnetworks.com
