Wireless connectivity and situational awareness are critical for warfighters in tactical and reconnaissance missions. High data rate communication links are essential in airborne communication systems for continuously exchanging information across the network and achieving situational awareness. To address this issue for the Air Force, IAI will develop multiple antenna, also called multiple-input, multiple-output, or MIMO technology for radios. This new product, MARWL (MIMO Appliqué for Radios without Modifying Legacy Waveforms), enables a high data rate by multiplexing several data streams. It improves reliability using spatial diversity, since each antenna experiences a different wireless channel, and the chances of all wireless links being poor are small. MARWL allows legacy radios to be MIMO-capable without modifying the waveform or the radios. This is preferable in the short term, compared to the costly and time consuming option of transforming or redesigning the waveform and the radio hardware to obtain MIMO capabilities on legacy radios. MIMO techniques significantly improve the throughput, reliability, and range of wireless communication systems. MARWL will extend the capability of using MIMO radios in other fields, such as Homeland Defense, first responder, and commercial systems.
