Integrated Wireless Communication Tools

Integrated Wireless Communication introduce a platform for RF communication systems in order to provide a prior experience with the extensive development and deployment of latest wireless technologies by providing an exposure towards designing various blocks of radio communication system using software and implementing over the associated SDRs (Software Defined Radio) module. Depending upon interest of the user, this lab ensures a convenient platform to explore projects/applications related to advance wireless technologies (Ex: OFDM, 4G LTE, 5G, WiMAX etc.

WaveGuru is an ideal tool for realization of networks starting from 2G to 5G and extending them to 5G concepts. Research fundamentally has always stopped at Matlab simulations in Academic institutes. SDR (Software Defined Radio) platforms have the mix of practical deployment scenarios and high performance computing platforms to scale the simulations to RF. This helps researchers to converge proposed solutions to overcome practical limitations or engineering problems. Universities can there by contribute immensely to disruptive innovation.

Lekha WaveGuru Nava – Hardware platform is an ideal platform for 5G Small cell, 5G CPE, 5G Fronthaul and several other communication and EW applications demanding wide band data transceiver and processing.

Lekha WaveGuru Nava – 5G Hardware platform board is a Xilinx RFSoC based SDR board capable of hosting multiple Waveforms. The on-board wideband and RF sampling ADC and DAC ensures that with minimal change in the RF front end circuit, several combinations of Transmit power, receive gain, Multiplexing schemes (TDD/ FDD), can be achieved.

The Platform solution comes in a combination of the RFSoC board and a Radio Front end (RFE) board. The two boards are connected through the LPAF Interconnect. The RFE board has the needed Balun circuits and the Gain stages to deliver 23dBm power per DAC port. The receive chain has a 18dB LNA stage.

The RFE board is available for 3.5GHz TDD operation.
