Wireless Challenges for RF, Millimeter-wave, and Photonic Technologies

Higher wireless data rates are demanding increased sophistication. Future networks (often called 5G) will need to meet demands on throughput, latency, and low-power requirements. Our speaker will discuss challenges confronting the currently-allocated RF spectrum and the potential for full-duplex communication (simultaneous transmit and receive) to increase spectral efficiency. He will present recent work at UCSB to realize full-duplex through the use of signal processing at the antenna.

Congestion in the RF bands is leading to commercial interest in millimeter-wave bands. To compete with RF bands, energy efficiency for short-range millimeter-wave links is needed. Significant advancements have been made in phased array and multiple-input/multi-output systems to support complex waveforms such as QAM and multiple simultaneous beams. Dr. Buckwalter will discuss the costs and benefits of such approaches and his lab's research into millimeter-wave systems.

Finally, he will present future plans to use photonic technologies to alleviate issues associated with millimeter-wave wireless networks.
