Companies make mobile voice and high-speed data economically viable in remote areas
Espoo, Finland –December 8, 2011
Telecom operators can now provide 3G mobile broadband to isolated and under-served areas via satellite backhaul. The approach that makes this possible combines Nokia Siemens Networks’ I-HSPA*with Evolution**satellite routers from VT iDirect, Inc. (iDirect), a world leader in satellite-based IP communications technology. The solution, successfully tested by both companies, can deliver downlink speeds of 10 Mbps*** per user from base stations in remote areas linked to a core network via satellite.
“The growing demand for mobile broadband is making operators look for efficient ways of delivering services in areas with low population density where terrestrial transport networks are less economically viable,” said Keith Sutton, head of the WCDMA business line for Nokia Siemens Networks. “Our I-HSPA architecture, together with iDirect’s satellite platform, makes 3G mobile broadband delivery possible in such areas. In addition to services such as social networking and video streaming, operators can deliver telemedicine and remote learning, helping bridge the digital divide.”
Nokia Siemens Networks’ I-HSPA uses a flat architecture for 3G networks that supports voice as well as high-speed data services. By allowing base stations to connect directly to the core network, I-HSPA eliminates the need for the intermediate nodes****found in traditional networks.
“With the adoption of 3G networks, the use of mobile data has grown exponentially and the mobile device is the primary form of connectivity for many people in remote and rural areas,” said Toni Lee Rudnicki, iDirect’s chief marketing officer. “Successful testing between iDirect and Nokia Siemens Networks’ I-HSPA has shown peak rates for satellite backhaul up to ten times higher than those achieved with other commercially available approaches to 3G. This is good news for those seeking true mobile broadband connectivity in hard to reach locations, as the Evolution product line can be rapidly deployed and provide a reliable satellite platform combined with the benefits of the I-HSPA architecture.”
Nokia Siemens Networks’ I-HSPA and iDirect’s Evolution product line are already commercially available to operators globally.

Notes to editors:
*Nokia Siemens Networks is driving industry leadership with its innovative I-HSPA offering that introduced a flat network architecture for the 3G world. I-HSPA enables simpler operations, better performances and higher scalability. Operators can cost-efficiently scale their networks to address rapidly growing traffic volumes. 3GPP-standardized I-HSPA is compatible with all HSPA devices and, along with the multi radio capabilities of Nokia Siemens Networks Flexi Base Stations, paves the way to LTE. The company has over 17I-HSPA customers to date.
**iDirect’s Evolution series of satellite routers complies with the DVB-S2 standard. Based on the Time Division Multiple Access (TDMA) model, Evolution supports bandwidth pooling and dynamic sharing between sites, dramatically lowering capacity costs as compared to expensive dedicated satellite links where bandwidth is statically allocated to each connection.
***During the tests, Nokia Siemens Networks and iDirect were able to achieve speeds as high as 9.8 Mbps in downlink, and 2.2 Mbps in uplink, while streaming video and data.
****As base stations are directly connected to the core network in I-HSPA, user traffic does not need to flow through intermediate nodes such as Radio Network Controllers (RNCs) and Serving GPRS Support Nodes (SGSNs) used in traditional 3G networks. In the case of satellite backhauling, the key differentiator is that with I-HSPA the traffic management functionalities of RNCs are on board of the base station and not located on a distant, physically separated RNC. This eliminates the low throughputs caused by the delays present in satellite connections, which are due to the much longer distance the signal needs to travel across.
