Exponential growth of mobile data traffic due to extensive uses of smartphones and tablets in various applications has created tremendous traffic burden on existing telecommunications infrastructure. Although significant efforts have already been made on spectrum efficiency by developing various innovative transmission technologies, we cannot jump over the hurdle imposed by the physical transmission limit (Shannon said so). Besides, efficient one-hop physical transmission technologies will not work well without effective network support for end-to-end user services. Cognitive radio technology was envisioned to unleash under-utilized licensed spectra and opportunistically utilize them to support communications services without affecting the incumbent spectrum users. Unfortunately, most research focuses on either cognitive radio design or spectrum sensing mostly for one-hop communications, which cannot handle end-to-end services effectively. LTE standardization has also looked into potential use of unlicensed bands (e.g., mmWave) to relieve the traffic burden. In this talk, the speaker will discuss design challenges in spectrum harvesting networks and then present a novel network solution to effective spectrum harvesting and optimization. This design not only enables network operators to tap unused (licensed/unlicensed) bands opportunistically and effectively, but also offers other optional strategies for significant network performance gain.
