enable many potential IoT applications and thus have gained widespread
attention recently. Existing mobile devices and telecommunication systems
may not be able to provide the highly desired low-latency computing and
communications services. To meet the needs of those applications, we
introduce Fog-Radio Access Network (F-RAN) architecture which brings the
efficient computing capability of the cloud to the edge of network. In this
talk, we first introduce the F-RAN and its rationale in serving ultra
low-latency applications; then we depict the need of a service framework for
F-RAN to cope with the complex tradeoff among the performance, the computing
cost, and communication cost. We will also present some other technical
challenges and open issues for deploying F-RAN in future mobile
telecommunications networks.
