Researchers Use Software-Defined Radio for Testing Millimeter-Wave Antennas
The wireless research arm of New York University recently announced plans to build a programmable testbed for prototyping millimeter-wave or mm-Wave. The testbed will eventually become available to universities, government agencies, and companies in the early stages of developing mm-Wave products and standards.
The testbed will combine high-gain phased array antennas with a software-defined radio (SDR), in which computer programs replace hardware components like filters and amplifiers. This combination will more precisely direct millimeter waveforms, which are normally concentrated into narrow beams and pointed directly at other antennas. The testbed is built around a baseband processor that will transmit and receive signals with high data rates and low latency.
