SDR-LAB

The Amitec SDR-LAB is Hardware + Open source Software + Syllabus + Book + Teaching material + Training + Support in complete package. It is the highest performing class of the Programmable Transceiver family of products, which enables students, researchers and engineers to rapidly design and implement powerful, flexible software defined radio systems. The SDR-LAB is ideally suited for applications requiring high RF performance and great bandwidth. Such applications include physical layer prototyping, dynamic spectrum access and cognitive radio, spectrum monitoring, record and playback, and even networked sensor deployment.

The systems offers MIMO capability with high bandwidth and dynamic range. The USB 3.0 interface serves as the connection between the SDR-LAB and the host computer. This enables the user to realize 40 MS/s of real-time bandwidth in the receive and transmit directions, simultaneously (full duplex). Four units may be connected to realize a complete 2x2 MIMO configuration using the optional MIMO cable. External PPS and reference inputs can also be used to create larger multi-channel systems.

The Hardware Driver supports Linux, Mac OSX, Windows. It also supports MATLAB, LABVIEW, GnuRadio, C++ and Python. RF-ASIC houses complete RF and DAQ subsystems on a single multi layer board with RF shielding for FCC and CE certified performance. It meets the unique architecture required for MIMO systems which are not part of traditional MIMO hardware’s using common clock for RF subsystems where a continuous RF phase tracking is required for implementing 4G LTE 3GPP release 11 onward. Coupled with these benefits it hosts on board RF Transceiver subsystems capable of tuning frequencies from 400MHz to 4GHz. Using software addreseable down-converter and up-converters it is possible to tune from 40KHz to 60GHz!

Hundreds of experiments designed at IIT Delhi are provided. The list is growing by the day to include most cases as per international curriculum.

WHY SOFTWARE DEFINED RADIO LAB ?

“Cost effective radio frequency technologies supporting the operation of software defined radios over a broad spectral range have begun to mature, allowing for the first time the use of software defined radio as an enabling technology for dynamic spectrum access systems with cognitive or smart radio functionality. This trend is expected to continue over the next several years, allowing SDR to finally achieve the defined vision of reducing costs in providing end-users with access to ubiquitous wireless communications – enabling them to communicate with whomever they need, whenever they need to and in whatever manner is appropriate.”
