Alternative Network Deployments: Taxonomy, characterization,
technologies and architectures
This document presents a taxonomy of "Alternative Network
Deployments", and a set of definitions and shared properties. It
also surveys the technologies employed in these networks, and their
differing architectural characteristics.
The term "Alternative Network Deployments" includes a set of network
access models that have emerged in the last decade. These networks
aim to bring Internet connectivity to people, using topological,
architectural and business models different from the so-called
"traditional" ones, where a company deploys or leases the network
infrastructure for connecting the users, who pay a subscription fee
to be connected and make use of it.
Several initiatives throughout the world have built large scale
Alternative Networks, using predominantly wireless technologies
(including long distance) due to the reduced cost of using unlicensed
spectrum. Wired technologies such as fiber are also used in some of
these alternate networks.
The emergence of these networks has been motivated by a variety of
factors such as the reluctance of network operators to provide wired
and cellular infrastructures to rural/remote areas. In these cases,
the networks have self-sustaining business models that provide more
localized communication services as well as Internet backhaul support
through peering agreements with traditional network operators. In
other cases, networks are built as a complement to commercial
Internet access provided by "traditional" network operators.

Internet-Draft Alternative Network Deployments January 2016
The present classification considers extant network models such as
Community Networks, which are self-organized and decentralized
networks wholly owned by the community; networks owned by individuals
who act as 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, and finally
there are networks that provide connectivity by sharing wireless
resources of the users.
Different criteria are used in order to build a classification e.g.,
the ownership of the equipment, the way the network is organized, the
participatory model, the extensibility, if they are driven by a
community, a company or a local stakeholder (public or private), etc.
According to the developed taxonomy, a characterization of each kind
of network is presented in terms of specific network characteristics
related to architecture, organization, etc.
