Nokia Siemens Network focused of All-IP Microwave Backhaul

Nokia Siemens Networks is introducing a microwave radio for the largely untapped “E-Band” frequencies* that are ideal for providing high-capacity mobile backhaul in dense urban areas. This new radio expands the spectrum that can be used by the company’s FlexiPacket Microwave platform, meaning that Nokia Siemens Networks becomes the only vendor to have a single mobile backhaul solution providing all-IP microwave connectivity from 6 to 80 GHz for a worldwide market.

 

“There are high expectations for 4G mobile networks – a peak capacity for high-mobility applications of at least 100 Mbps,” said Vesa Tykkyläinen, head of Microwave Radio Transport at Nokia Siemens Networks. “These requirements, far beyond the current capabilities of 3G, will be first addressed by LTE and the evolving WiMAX standards. This increase in over-the-air bandwidth will drive a corresponding increase in the capacity requirements for mobile backhaul networks and will require an end-to-end all-IP microwave solution. Our the new E-Band radio helps to address this challenge.”

 

With the aggregation of multiple LTE base stations in dense urban areas, the backhaul traffic capacity requirements per cell site will likely exceed 500 Mb/s and even reach 1 Gb/s. Nokia Siemens Networks’ new 70/80 GHz E-Band radio, which is integrated into the FlexiPacket Microwave solution, provides up to 2.5 Gbit/s of transport capacity for each GHz of radio frequency channel over a distance of 3 kilometers.

Furthermore, the licensing costs for the E-Band spectrum are typically much lower than the corresponding licenses for 6-38 GHz spectrum, with many regulators, for example in the U.S. or the U.K., looking for the “light licensing” approach.

 

The Nokia Siemens Networks’ FlexiPacket offering addresses the whole chain in mobile networking, including radio, hub-site and network management, with carrier-grade quality of service.

Nokia Siemens Network Data Network Optimisation feature

Nokia Siemens Networks has unveiled an upgrade to its core mobile network technology that enables operators to offload Internet traffic at an optimal point in the network - typically close to an Internet peering point - in order to minimize the distance it is transmitted. This saves transport and traffic processing costs.

"Operators typically need to deploy relatively costly servers to process mobile data traffic," said Matti Palomaki, head of Packet Core product management at Nokia Siemens Networks. "Our new approach allows a high volume of Internet traffic, or any operator-specified traffic, to bypass these processing servers and legacy packet core gateway nodes (GGSNs). In the era of smartphone-induced data growth, such "offloading" of traffic can deliver significant savings in next-generation HSPA and LTE networks."

Traffic offload can be deployed across Nokia Siemens Networks' Flexi Network Gateway (NG) and as a simple software upgrade to the Serving GPRS Support Node (SGSN). The Flexi NG and SGSN are key elements of Nokia Siemens Networks' evolved packet core (EPC). Traffic offload can be deployed in both distributed and centralized gateways in 2G, 3G or LTE networks. The first phase of traffic offload is already available.

The network architecture for traffic offload is the simplest possible. As offloading takes place in the Flexi NG mobile gateway, it does not require additional network elements along the signalling and data paths. The solution supports subscriber mobility in an optimal manner and can reduce delays in data transmission to improve the experience for people using real-time applications over mobile networks.

In instances where an operator has distributed Internet peering points, the Flexi NG can easily be deployed as a distributed gateway at each of these points to reduce transport network costs, while the SGSN intelligently selects which of the distributed mobile gateways is closest to the subscriber.
