MULTIPLE INPUT MULTIPLE OUTPUTMIMO DEVELOPMENT TEST BED LAB MIM04

Description:

The Amitec MIMO-LAB is a software programmable hardware transceiver which allows limitless telecommunication laboratory experiments to be performed on a single device. The entry barrier is lowered to include the under graduate students by providing a graphical programming environment. The burden on faculty is lowered by using courseware designed at IITD from simple FM to most complex MIMO. Lab technicians are eased by integrated hardware and software from same source for trouble free performance.

The system is ideally suited for applications requiring high RF performance and great bandwidth such as physical layer prototyping, dynamic spectrum access and cognitive radio, spectrum monitoring and even networked sensor deployment.

The Superspeed USB 3.0 interface at 5Gbps serves as the connection between the MIMO-LAB and the mobile workstation. This enables the user to realize 40 MS/s of real-time bandwidth in the receive and transmit directions, simultaneously (full duplex). FPGA is autoloading so hadrware is plug and play as a pen drive! No need to program the FPGA for most cases!

The systems offers MIMO capability with high bandwidth and dynamic range. 4 pcs of radios may be connected to realize a complete 2x2 or 3X1 MIMO configuration. External PPS and reference inputs can also be used to create larger multi-channel systems. ASIC houses complete RF and DAQ subsystems on a single board. Coupled with these benefits it hosts onboard RF Transceiver subsystems capable of tuning frequencies from 400MHz to 4GHz.
