By bringing the advantages of flat architecture to 3G networks, Nokia Siemens Networks’ I-HSPA helps you cope with the challenge of rapid growth in data traffic while maintaining profitability and preserving end-user quality of experience.
Flat architecture means simpler operations, better performance and higher scalability.
With flat architecture, you can avoid investing in the larger and larger radio network controllers needed for the ever-increasing signaling load and traffic. This is especially important today, with the fast and unpredictable growth in data traffic.
By applying the advantages of flat architecture to existing High Speed Packet Access (HSPA) 3G networks, I-HSPA gives you the benefits of a more advanced architecture while leveraging the large existing installed base of 3G devices.
In I-HSPA, Radio Network Controller (RNC) functionality is moved into our Flexi Base Transceiver Station (BTS), allowing for a unique RNC-less architecture.
Because I-HSPA traffic does not traverse the RNC, there’s no need to expand RNC capacity to support increasing traffic.
I-HSPA greatly increases the number of smartphones that can be served simultaneously, because RNC functionality is built into each BTS and the relevant signalling traffic is handled in a distributed manner across the network, rather than in few concentrated RNC sites.
The leaner architecture of I-HSPA ensures performance improvements, especially in terms of lower latency for packet connections.
This is particularly relevant when satellite backhaul needs to be used. Because RNC functionality is part of the BTS, the latency intrinsic to satellite connections does not affect the protocols that control the flow of data traffic between BTS and RNC. In this way, higher peak rates can be achieved.
For example, in recent field tests we could measure up to 9.8 Mbps in downlink and 2.2 Mbps in uplink for streaming services. No other vendor has been able up to now to provide such high peak data rates when satellite backhauling of the base stations is in use. See also the related press release.

This makes I-HSPA a unique solution for mobile broadband services in areas that are underserved or unreachable by terrestrial connectivity infrastructure.
Beyond improving smartphone services and data services in general, our I-HSPA provides native, full support for circuit-switched (CS) based, voice services.
I-HSPA BTS’s can be directly connected to CS core networks, without rerouting voice traffic to other intermediate nodes.
In addition to interworking with our radio, circuit core and packet core network products, our I-HSPA also supports those of other vendors.
The business benefits
- Saves CAPEX by minimizing new investment to cope with the surge in smartphones and data traffic, maximizing the number of smartphone users delivering the advantages of an LTE-like flat architecture along with the widespread adoption of 3G end user devices
- Improves your end-customer user experience with minimal latency and state-of-the-art transfer rates
- Protects you investment by upgrading easily to LTE via software, allowing you to reuse the same network topology and equipment to deploy and activate LTE and letting you keep HSPA and LTE services active simultaneously
