Wireless data traffic continues to grow rapidly, with the growth in the number of connected devices and device capabilities. This demand is driving significant wireless network investments, as well as architecture evolution such as small cells (which enable greater spectrum reuse), greater use of Wi-Fi (to offload wide area networks), and proposals such as spectrum sharing (as a means of making more spectrum available). This talk discusses some of the research and engineering challenges that need to be addressed to fully realize these new architectural concepts while meeting customer expectations for service quality.
