Bridging the Data Charging Gap in the Cellular Edge

The intelligent wireless edge is redefining our digital lives. By shifting the computation from cloud to edge, it promises ultra-low latency for the emergent applications, such as real-time video analytics, safe self-driving, virtual reality, online games, and many more. Many edge scenarios need low latency in indoor/outdoor, and static/mobile settings. A promising solution is the cellular edge (Figure 1, such as Amazon Wavelength [3]). To date, the 4G LTE and emerging 5G cellular networks are the largest wireless infrastructures that offer ubiquitous coverage and seamless mobility support. They operate in the licensed spectrum and support carrier-grade QoS for low latency.
