New End-to-end LTE Solution from Nokia Siemens Networks-- 19/02/2008
New End-to-end LTE Solution from Nokia Siemens Networks
Nokia Siemens Networks launched an LTE - solution for radio and core networks — its new Flexi Multimode Base Station, Mobility Management Entity (MME), and System Architecture Evolution (SAE) Gateway (News - Alert). The solution is designed to assist mobile operators in meeting consumer demands for high speed data and capacity beyond 3G by implementing a seamless upgrade to Long Term Evolution (LTE)/System Architecture Evolution (SAE) networks.
The LTE solution is best suited to those operators who are new to the industry or are currently upgrading their existing GSM/WCDMA/HSPA networks for fast Internet services with mobile broadband. LTE is expected to provide a joint evolution for both 3GPP and 3GPP2 operators, making it a true global roaming technology. Ideally, this solution would be the next step for CDMA operators in order to achieve higher speeds and capacities.
Ari Lehtoranta, head of Radio Access, Nokia Siemens Networks, spoke in detail about the launch of the LTE: “Today, we are proud to present Nokia Siemens Networks’ new high-power Flexi Multimode Base Station, which is software upgradeable to LTE. Operators will greatly benefit from LTE as it lowers the cost per gigabyte of data, decreases the network latency and improves capacities and data throughput for mobile broadband. And, consumers will be able to enjoy an optimal user experience with the highest data speeds of mobile Internet services.”
Nokia Siemens Networks Flexi Multimode Base Station is the latest in the lineup of small, modular, and energy efficient Flexi Base Station products, which makes best use of the software defined radio concept. As of 3Q 2008, the Flexi Multimode Base Station can be deployed with WCDMA/HSPA and the software can be upgraded to LTE as of the latter half of 2009. The new base station is expected to maintain the highest power with the smallest size, thus helping minimize network deployment and operational costs, which, in turn, has a tremendous positive effect on lowering energy consumption. The Flexi Base Station lineup currently supports FDD and TDD based technologies and forms an optimal platform for LTE.
“To support the launch of our end-to-end LTE solution we are proud to announce the readiness of our LTE/SAE core network to serve the market with theNokia Siemens Networks’ ( News - Alert) SGSN, as well as the Flexi ISN, upgradeable to LTE/SAE,” commented head of Converged Internet Connectivity—Nokia Siemens Networks Petri Pöyhönen. “With direct tunnel functionality, we are already providing innovative flat core architecture in today’s HSPA networks, setting the stage for streamlined core networks that will be able to carry the massive Internet payloads we expect to see over LTE.”
