AT4 demonstrated its E2010 Broadband Wireless Test Set at the 2009 Mobile World Congress (MWC) last month in Barcelona, performing Long-Term Evolution (LTE) Layer 1 testing, protocol testing, and video streaming with real physical-layer (PHY) user equipment (UE). By covering the entire LTE UE lifecycle, the company said it demonstrated the E2010’s flexibility and power for R&D and certification measurements.

During the demonstration, AT4 used real PHY UE to show the E2010’s video streaming capabilities using 64QAM (quadrature amplitude modulation), parametric measurements like power versus time, power versus frequency, and modulation quality. AT4 also demonstrated a protocol test session using the system’s integrated testing and test control notation (TTCN) environment. 

The E2010 Broadband Wireless Test Set is a state-of-the-art multi-RAT (remote administration tool) platform that integrates dual radio faces, a real-time PHY and channel emulator, a spectrum analyzer, and a 3GPP-compliant Rel-8 protocol stack in a single box. It also supports multiple-input multiple-output (MIMO) 2x2 (future 4x4) and multiple cell emulation. Designed with expandability in mind, it supports test applications and scenarios ranging from design and R&D to conformance and certification testing.
