Understanding Radio Channel - Part 2: Reaching a Data Rate of 100Mbit/s with LTE

New 4G LTE technology promises incredible data rates up to 100 Mbit/s from base station to end users. Considering the variability of radio conditions, is it really possible to achieve such a high data rate in the real network? Multi-antenna technologies such as MIMO and beamforming are designed to deliver the higher data rates. Under optimal conditions this is possible, but the performance is highly dependent on radio link conditions. Given ideal MIMO channel conditions, 100 Mbit/s maximum capacity of LTE is achievable, but in poor channel conditions, the data rate can be significantly lower. Since maximum data rate depends so heavily on radio channel conditions herein lies the major challenge. The performance of the LTE base station, chipset or terminal has to be optimised and tested for various different radio environments – but how can that be done? The answer is revealed in this webinar - Understanding the Radio Channel - Part 2: Reaching a Data Rate of 100Mbit/s with LTE.

This webinar presents the key concepts of LTE performance testing; especially for MIMO and beamforming technologies. The use of state of the art channel models for multi-antenna testing are also explained. The key element in MIMO testing is accurate emulation of antenna to antenna correlation. This webinar also explains how geometry-based stochastic channel models are employed to create channel models that offer pragmatic control over angular parameters. By using these models, the true performance of beamforming technology can be tested in different radio conditions, which ensures that products function properly when deployed in real networks.


Mr. Janne Kolu, Vice President, EB Test Tools
Janne Kolureceived his MSc degree in Physics from the University of Oulu, Finland in 2000. He joined Elektrobit Ltd, Finland, in 1999, where his activities have included channel modeling research and radio channel emulator development projects. He has contributed to EU COST projects and also to 3GPP standardization work. At EB he has held several different positions related to the development of advanced radio channel emulation tools. Mr. Kolu has contributed to several scientific articles and he holds several patents. He is currently Vice President at EB.


Mr. Petteri Heino, Product Manager, EB Test Tools
Petteri Heino is Product Manager for EB Propsim F8 channel-modeling applications. He has more than 10 years’ experience with radio-channel research and emulator products. Before his current position, he was responsible for the EB Propsound channel sounder product, a role in which he executed channel-measurement and -modeling projects globally for several research organizations and companies. He has also been the EB delegate to 3GPP UMTS/LTE standardization projects.
