A networking researcher interested in the challenges of infrastructure at the end of the tail of connectivity

abstract:

The radio interfaces and network architectures of WiFi and cellular systems are converging along many dimensions. While both systems are largely adopting the centralized architecture of traditional cellular deployments, this design comes with fundamental disadvantages that limit how these networks grow and develop. As a response, we present Distributed LTE (dLTE), an architecture offering the high radio performance of licensed and coordinated waveforms as well as the openness to organic expansion and growth of traditional WiFi. We challenge the assumption that good performance requires a centralized packet processing core, and propose hybrid approaches to coordination that prioritize system openness. We argue that dLTE is a particularly good fit for rural areas, where the LTE waveform is more appropriate than WiFi, yet it is uneconomical for centralized providers to deploy traditional cellular systems.
