Agilent Technologies has introduced LTE-Advanced 8x8 MIMO signal-generation and analysis solutions. LTE-Advanced supports a maximum bandwidth of 100 MHz by aggregating up to five component carriers, each up to 20 MHz wide, and improved multi-antenna techniques in both uplink and downlink. For downlink, LTE-Advanced introduces transmission mode 9, which enables Multiple-Input Multiple-Output (MIMO) with up to 8 spatial streams and antennas.
The solution involves Signal Studio and 89600 VSA software for testing physical layer implementations of LTE-Advanced devices, and the multi-channel signal analyzer enables full analysis of LTE-Advanced standards on next-generation antennas, base stations and user equipment. 89600 VSA used to do phase-synchronous and cross-channel measurements with up to eight RF channels in a single mainframe.
"As a recognized leader and provider of world-class LTE solutions, Agilent plays a pivotal role in the development, revision and implementation of the 4G technology, LTE-Advanced," said Andy Botka, vice president and general manager of Agilent's Microwave and Communications Division. "Our first-to-market 8x8 MIMO test solutions further complement Agilent's comprehensive portfolio of LTE-Advanced signal-generation and analysis solutions, and reaffirm our commitment to actively leading the evolution of LTE to a 4G technology."
