EB, a developer of embedded technology solutions for automotive and wireless industries, announced the availability of its Spatial Channel Modeling Tool for its EB Propsim radio channel emulators for Mobile WiMAX and 3GPP LTE. The Spatial Channel Modeling Tool supports both the use of SCM and SCME channel models and is ideal for testing a range of applications including mobile devices and base stations.
EB’s Spatial Channel Modeling Tool is based on a geometry-based stochastic modeling method for system-level emulations between multiple base stations and multiple mobile stations. Performance metrics such as throughput and delay are measured over a large number of emulation runs, called “drops”, which consist of a predefined number of radio frames. During a drop, the channel experiences fast fading according to the movement of the terminals. The new tool allows users to accurately control and adjust the most crucial parameters affecting single link level and system level channel conditions including scenarios with multi-users, handoffs, interference and other multiple-input multiple-output (MIMO) antenna configurations. EB’s Spatial Channel Modeling Tool helps handset, mobile terminal and base station developers reveal MIMO transceiver design errors and optimize their network level algorithms to perform maximum data throughputs in most channel conditions occurring in a field to ensure the best end-user experience possible.
“The move from conventional tapped delay line channel models to spatial channel models is truly a huge step towards the use of more realistic radio channel models in wireless testing,” said Tommi Jämsä, senior manager, Standardization and Networking of EB’s Wireless Communication Tools business. “This step is a trend setter for future channel modeling towards 4G standards and beyond.”
EB is actively involved in the development and definition of industry standards for wireless communications and utilizes this work for its customers by designing and implementing the conformance and beyond conformance testing requirements in its testing solutions. In the past years, EB has actively contributed spatial channel models to number of different standards such as ITU-R IMT-Advanced, 3GPP, IEEE 802.16m and WiMAX Forum. EB has acted as a leader of a channel model work package in The European Wireless World Initiative New Radio (WINNER) project and as a chairman of channel model drafting group in ITU-R IMT.EVAL. Recently, WINNER-based models were adopted by ITU, 3GPP and IEEE.
The Spatial Channel Modeling Tool is available for both the EB Propsim C8 and EB Propsim F8 radio channel emulators and has already been delivered to several industry leaders.
