We are the world’s specialist in mobile broadband. From the first ever call on GSM, to the first call on LTE, we operate at the forefront of each generation of mobile technology. We help our customers meet the demands of a world seeking universal connectivity and content. Together, we deliver the innovations in mobile technology and services that enable people and businesses everywhere to do more than ever before.
Our Technology vision for 2020
Mobile networks are able to deliver one Gigabyte of personalized data per user per day profitably
Therefore mobile networks need to undergo a fundamental transformation. The key requirements are:
Support up to 1000 times more capacity: higher spectral efficiency, more spectrum and small cells are needed.
Reduce latency to milliseconds: bandwidth, proximity and control will solve the latency challenge.
Teach networks to be self-aware: cognitive networks can autonomously handle complex end-to-end network and service management.
Reinvent the Telcos for cloud: software defined networks for an end-to-end virtualized service delivery.
Flatten total energy consumption: efficient radio technologies, high utilization and network modernization will flatten network energy consumption despite traffic growth.

HSPA+ Boosters for Multifold Performance
Attractive HSPA-capable smartphones are leading to increased traffic volumes and growing demand from users for even higher data rates and lower latencies. HSPA continues to evolve to bring many enhancements that boost network capacity and user performance significantly, and all are backwards compatible and supported by most new devices. This paper explains the latest features available to increase the performance of HSPA networks. Read the full paper.
Harri Holma joined Nokia Research Centre in 1994 and received his M.Sc. from Helsinki University of Technology 1995. He has been with Nokia Networks since 1998, located both in Finland and in USA during that time. Harri Holma is currently working as a Nokia Siemens Networks Fellow with special interest on radio system performance. He completed his PhD at Helsinki University of Technology in 2003. Dr. Holma has edited the books "WCDMA for UMTS", "HSDPA/HSUPA for UMTS", "LTE for UMTS", “Voice over LTE (VoLTE)” and “LTE Advanced” and contributed to a number of other books in the radio communication area.
Long Term HSPA Evolution paper
Despite the rapid development and growing deployment of LTE, HSPA continues to evolve to bring improved performance. Release 11 contains a number of features that fulfill the IMT-A requirements for HSPA. 4x4 MIMO, Multiflow, and 8 carrier HSDPA improve the downlink peak data rate, average and cell edge spectral efficiency, while UL Beamforming, UL MIMO and 64QAM improve the uplink peak data rate, average and cell edge spectral efficiency. Further enhancements to CELL_FACH give increased device battery savings, better mobility to and from LTE and increased user data rates in CELL_FACH mode.
Yet, HSPA evolution will not stop there and will continue to improve in several areas yet to be standardized in Release 12. These improvements will help HSPA tackle the large amount of data that needs to be served before offloading to LTE. Read the full paper.
Jeroen Wigard received his M.Sc. in 1995 from Delft University of Technology, the Netherlands. In 1999 he finished his Ph.D. on capacity enhancements in FH GSM networks in Aalborg University, Denmark. Since then he has been with Nokia Networks and Nokia Siemens Networks in Aalborg, Denmark, working with Radio Resource Management for GSM, GPRS, WCDMA, HSPA, HSPA+ and LTE.
Patrick Marsch received his M.Sc. and Ph.D. degrees from Technische Universität Dresden, Germany, in 2004 and 2010, respectively. Since early 2011, he is with Nokia Siemens Networks, where he is heading a research team covering a large span of radio research from HSPA standards research to beyond 4G. He has (co-)authored 45+ journal or conference publications in the field of mobile communications and received the Johann Philipp Reis prize for pioneering work in the field of CoMP.
Karri Ranta-aho received his M.Sc in 1997 from Tampere University of Technolofy, Finland.
In 1996 he joined Nokia Mobile Phones and has been working in 3GPP standardization of WCDMA/HSPA and LTE radios with Nokia Networks and Nokia Siemens Networks since 2002.
Bandwidth Proximity Control: a recipe for low latency networks. White paper available now
Low latency is the key to instant satisfaction for mobile broadband users. Latency has a major impact on services and applications, such as mobile video communication, live video streaming and multi-player gaming. It may be impossible to predict the kinds of applications that people will be using in five years’ time, but one thing is certain – we’re going to see more emphasis on real-time performance in mobile services.
Three key factors need to be addressed to create a low-latency mobile network: bandwidth, proximity and control. They are discussed in the paper. Latency is an opportunity for network operators to change the game in content delivery by enhancing the customer experience of latency-sensitive applications.
How QoS differentiation enhances the OTT video streaming experience
Cellular networks are more and more impacted by the growing popularity of Over the Top (OTT) video streaming services. Consumers expect a high quality experience when watching OTT video streams, whether it be short form YouTube videos or long form movies or television programs from providers such as Netflix.
Nokia Siemens Networks has studied how Netflix video streaming quality can benefit from the use of QoS mechanisms over a LTE network as congestion levels increase. Lab results show that QoS mechanisms are an effective tool for operators to provide differentiated delivery of video streaming services transporting which creates the opportunity for operators to participate in the mobile video value chain beyond just basic transport.
