Telecommunication industries and spectrum regulation authorities are increasingly interested in unlocking the 12 GHz band for two-way 5G terrestrial services. The 12 GHz band has a much larger bandwidth than the current sub-6 GHz band and better propagation characteristics than the millimeter wave (mmWave) band. Thus, the 12 GHz band offers great potential for improving the coverage and capacity of terrestrial 5G networks. However, interference issues between incumbent receivers and 5G radio links present a major challenge in the 12 GHz band. If one could exploit the dynamic contexts inherent to the 12 GHz band, one could reform spectrum sharing policy to create spectrum access opportunities for 5G mobile services. This article makes three contributions. First, it presents the characteristics and challenges of the 12 GHz band. Second, we explain the characteristics and requirements for spectrum sharing at a variety of levels to resolve those issues. Lastly, we present several research opportunities to enable harmonious coexistence of incumbent licensees and 5G networks within the 12 GHz band.

Compete or Coordinate? Analysis of Spectrum Sharing Strategies for Local Wireless Services
In this paper, we consider a setting in which geographically constrained “local” wireless services operate in a shared spectrum band and compete in the same market for customers who fall within their local coverage areas. When their desired coverage areas overlap, there are multiple ways that spectrum usage could be coordinated. We discuss ways in which this coordination could arise. We then characterize the market impacts of different forms of coordination via a framework of Cournot competition with congestion. Our analysis illustrates the economic trade-offs of different coordination mechanisms for local services.

In this paper or poster presentation, we hope to present to and interact with our audience with respect to a key touchpoint in our national study of engineering education reform. Based on an NSF collaborative grant, our project team has conducted approximately 280 semi-structured interviews at over 40 different institutions with regards to change processes that operate within engineering education. Originally inspired by our earlier work on ABET, we framed our study around questions of governance, namely how national organizations and national conversations do and don’t shape changes in engineering education. However, our early interviews made it very clear that US engineering schools viewed themselves as participating in a competitive market, where local initiatives and innovations are as important if not more important to their student experience and institutional reputation. This said, market mechanisms and the way in which local innovations circulate (entrepreneurship, maker spaces, humanitarian engineering) are themselves a form of coordination, pointing to more subtle modes of governance that operate within engineering education. Drawing on the multi-theory framework of Austin and Jones’ for understanding Higher Education Governance (2015), we use this presentation to begin to tease apart the different modes through which change occurs within engineering education.more » « less

Increased demand for productive uses of energy is a driver of energy consumption. Low-income households in the off-grid market have a budget constraint. By understanding the energy priorities of low-income households in the off-grid market, utilities can develop innovative solutions for servicing the market. This paper builds on recent literature on productive uses of electricity for increased investment and pay back for micro-grid investment across the eight productive user categories that were developed in Rwanda. We ask: how can the range, success, and benefits of productive uses of energy be expanded in resource-constrained settings? To answer the research question, we address the need for supporting infrastructure of business development services, energy services bundling, and utility policy instruments that support productive use of energy. We created metrics for prioritizing productive uses of energy in the off-grid market. In the face of a budget constraint, low-income households that prioritize domestic over business and services uses of energy need integrated services that support the consumptive-productive-service link. Realistic cost-benefit analyses are needed. Solar irrigation as a small industry case in Rwanda can achieve at best a 3-year payback period if it can increase productivity by 54%. We offer recommendations to increase energy demand from productive uses of energy in the off-grid market: work with local cultural norms to support business development; develop realistic cost-benefit analyses based on local data, and partner with business training service providers.more » « less

The recent framework for spectrum sharing in the 3.5 GHz band allows for Environment Sensing Capability operators (ESCs) to measure spectrum occupancy so as to enable commercial use of this spectrum when federal incumbent users are not present. Each ESC will contract with one or more Spectrum Access Systems (SASs) to provide spectrum occupancy data. Commercial firms using the band will in turn contract with a SAS to determine when it can access the spectrum. Initially, the decisions of which ESC and SAS to partner with will likely be based on long-term contracts. In this paper, we consider an alternative framework, in which an ESC sells its spectrum management information via a spot market so that from periodto- period a commercial user can select a different ESC from which to acquire spectrum measurements. We develop a game theoretic model to analyze such a market and show that using such a spot market may better enable multiple commercial firms to operate in a given spectrum band. We also show that this increased competition may not benefit consumer surplus unless firms adopt a non-stationary strategy profile.more » « less

Fault-tolerant coordination services have been widely used in distributed applications in cloud environments. Recent years have witnessed the emergence of time-sensitive applications deployed in edge computing environments, which introduces both challenges and opportunities for coordination services. On one hand, coordination services must recover from failures in a timely manner. On the other hand, edge computing employs local networked platforms that can be exploited to achieve timely recovery. In this work, we first identify the limitations of the leader election and recovery protocols underlying Apache ZooKeeper, the prevailing open-source coordination service. To reduce recovery latency from leader failures, we then design RT-Zookeeper with a set of novel features including a fast-convergence election protocol, a quorum channel notification mechanism, and a distributed epoch persistence protocol. We have implemented RT-Zookeeper based on ZooKeeper version 3.5.8. Empirical evaluation shows that RT-ZooKeeper achieves 91% reduction in maximum recovery latency in comparison to ZooKeeper. Furthermore, a case study demonstrates that fast failure recovery in RT-ZooKeeper can benefit a common messaging service like Kafka in terms of message latency.more » « less
