Aeroflex HSDPA Multi-UE Option - AEROFLEX - #2

Text version of the page

Taking the TM500 further Available as an upgrade to the TM500, the first commercial 13.97 Mbps capable Test Mobile platform, the HSDPA Multi-UE Option simulates the operation of 32 UEs in fading channel conditions, providing: • Real-time feedback of channel quality, downlink power control and HARQ response • Ability to configure combinations of UEs from all capability classes • Independent downlink channel environments for each UE • Data integrity verification through full simultaneous decode of all HSDPA signalling and data channels on the cell • Node B stress testing by cascading several Multi-UEs • Interoperability with the TM500 test mobile for AS/NAS protocol or TCP/IP service demonstrations in a high-load environment Up and running Existing users of the TM500 HSDPA test mobile will be immediately familiar with the Multi-UE control and measurement environment. Multi-UE Script Editor – provides a graphical user interface to help in generating control scripts for Multi-UE operation. In addition, Layer 1 scripts from TM500 testing may be imported directly to run in the Multi-UE test environment. Multi-UE Data Logger – provides graphical control and measurement for the Multi-UE. A comprehensive suite of measurement capabilities is provided with values logged to file for offline analysis or displayed in real-time charts. Measurements may apply to individual, multiple or all UEs in the system. Channel Model Editor – a graphical tool for generating the downlink propagation conditions for each mobile. The fading channel profiles may be derived directly from the TM500 logs or calculated by specifying a path loss profile and mobility conditions. In a real world scenario, each mobile will experience its own independent fading channel conditions. The quality of the received signal at the mobile will depend upon factors such as path loss, multipath and cell interference and the mobile's velocity. This received signal quality will determine the mobile's ability to decode the HSDPA data and the channel quality information that it reports to the Node B. Aeroflex has introduced the concept of mobility models to the TM500 Multi-UE to represent downlink channel behavior. Each mobile monitors the downlink channel conditions and generates responses based upon the simulated environment. The Node B receives consistent information from each of the 32 mobiles, with mobiles experiencing good simulated channel conditions reporting high CQI channel quality and high data throughput.
