Metropolitan Wi-Fi Research Network at the Los Angeles State Historic Park

UCLA is deploying a metropolitan-scale Wi-Fi mesh network near Downtown Los Angeles. It supports research in community-based urban participatory sensing, which focuses on how people can use their everyday mobile phones as sensors for data gathering on personal, community, and urban scales.  Moreover, we will use it to explore Cultural Civic Computing, a service-oriented urban computing model in which neighborhoods power the processes of imagining, specifying, and designing technology infrastructure for public places. This work provides infrastructure with which to explore the potential that a large scale Wi-Fi deployment offers multicultural communities in investigating and reclaiming their own environments, and creating healthy and livable cities.  It also enables public exploration of creativity and cultural identity, as well as the diverse histories of our cities and neighborhoods

Alternative networks: toward global access to the Internet for all

It is often said that the Internet is ubiquitous in our daily lives, but this holds true only for those who can easily access it. In fact, billions of people are still digitally disconnected, as bringing connectivity to certain zones does not make a good business case. The only solution for these unsatisfied potential users is to directly undertake the building of the infrastructure required to obtaining access to the Internet, typically forming groups in order to share the corresponding cost. This article presents a global classification and a summary of the main characteristics of different Alternative Network deployments that have arisen in recent years with an aim to provide Internet services in places where mainstream network deployments do not exist or are not adequate solutions. The Global Access to the Internet for All Research Group of the Internet Research Task Force, where all authors actively participate, is interested in documenting these emerging deployments. As an outcome of this work, a classification has converged by consensus, where five criteria have been identified and, based on them, four different types of Alternative Networks have been identified and described with real-world examples. Such a classification is useful for a deeper understanding of the common characteristics behind existing and emerging Alternative Networks

Alternative Network Deployments: Taxonomy, Characterization, Technologies, and Architectures

This document presents a taxonomy of a set of "Alternative Network Deployments" that emerged in the last decade with the aim of bringing Internet connectivity to people or providing a local communication infrastructure to serve various complementary needs and objectives. They employ architectures and topologies different from those of mainstream networks and rely on alternative governance and business models. The document also surveys the technologies deployed in these networks, and their differing architectural characteristics, including a set of definitions and shared properties. The classification considers models such as Community Networks, Wireless Internet Service Providers (WISPs), networks owned by individuals but leased out to network operators who use them as a low-cost medium to reach the underserved population, networks that provide connectivity by sharing wireless resources of the users, and rural utility cooperatives
