Rohde & Schwarz exhibited its CMW270 WiMAX tester as well several LTE test offerings, including the CMW500 UMTS LTE protocol analyzer. The company highlighted software options for its signal generators and analyzers that support LTE uplink and downlink measurements as well as a software option that supports physical layer tests on HSPA+ receivers, baseband modules, and RF front ends. An additional software option for the SMU200A and SMATE200A vector signal generators and AMU200A baseband signal generator supports assisted GPS (A-GPS) test.

R&S also noted that it has added MIMO precoding and channel coding to its LTE signal generators. In addition, the company demonstrated a 2x2 MIMO receiver test using an SMU200A RF signal generator, an AMU200A baseband generator, and a fading simulator. The combination supports WiMAX test for LTE, WiMAX, WLAN, and HSPA+.
Agilent Technologies demonstrated its WiMAX and 3GPP LTE test portfolio. WiMAX tools on display included signal creation and analysis software for Wave 2 Mobile WiMAX and MIMO development using Agilent Infiniium oscilloscopes and MXG signal generators. Also on display was Wave 2 MIMO testing capability (featuring the E6651A WiMAX tester), the N8300A wireless networking test set, the J7910A WiMAX signaling analyzer, and the Agilent WiMAX drive test system. 3GPP LTE analysis tools on display included a new 3GPP LTE protocol development offering based on the Agilent E6620A wireless communications test set and Anite’s SAT LTE protocol development toolset.
Anritsu focused on LTE and HSPA+ products, highlighting its MD8480C signaling tester, which supports HSDPA/HSUPA test; its MG3700A vector signal generator, which provides analysis capabilities for orthogonal frequency division multiple access (OFDMA) and MIMO LTE test; and the MS269xA signal analyzer, which supports LTE measurements. The company also introduced three software packages for its MS269xA signal analyzers: the MX269020A LTE downlink measurement software, the MX269021A uplink measurement software, and the MX269908A LTE IQproducer software.
