Description

Complete Full-Duplex 5G Massive MIMO Lab System with 16 TX and 16 RX channels.

Frequency Range of 50 MHz to 3.8 GHz.

The Ultra Low-latency PCI-E interface at 10Gbps serves as the connection between the baseband section and the mobile workstation. This enables the user to realize 10Gbps of real-time throughput in the receive and transmit directions in full duplex mode.

The next generation of wireless networks need to provide enhanced data rates for mobile broadband applications along with low latency and reliability for machine and vehicular communication. Spectrum in conventional cellular frequency bands of 500MHz to 4 GHz is crowded and exorbitantly expensive. For optimum utilization and mass deployment, there are many challenges which need to be addressed such as development of new algorithms, technologies and air interfaces along with energy efficiency and channel models.

The 5G MASSIVE MIMO LAB is a software programmable hardware transceiver which allows limitless research and development along with laboratory experiments to be performed on a single device. The system is ideally suited for applications requiring high RF performance and great bandwidth such as 5G Physical layer prototyping, Dynamic Spectrum Access and Cognitive Radio, Spectrum Monitoring and even Networked Sensor Deployment.

The system has modular architecture with high performance synthesizers and integrated mixers allowing baseband processing. The system has independently programmable transmitter and receiver sections with programmable frequencies, ADC and DAC sampling rates, filter bandwidths, variable gain amplifiers, LNA and PA. The entry barrier is lowered to include the 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 systems. The Ultra Low-latency PCIE interface at 10Gbps serves as the connection between the baseband section and the mobile workstation. This enables the user to realize 10Gbps of real-time throughput in the receive and transmit directions in full duplex mode.
