e live in a world in which there is a great disparity between the lives of the rich and the poor.
Information and communication technology
(ICT) offers promise in bridging this digital divide through
its focus on connecting human capacity with computing and
informational content. It is well known that Internet access
has the capability of fostering development and growth by
enabling access to information, education, and opportunities. Unfortunately, the availability of Internet in worldwide
terms is limited, with an estimated 4 billion people — an
estimated 60 percent of the human population — lacking
Internet access. People in rural areas are particularly hard
hit since socio-economic factors preclude the provisioning
of Internet access and mobile telephony in these sparsely
populated low-income areas.
There is a growing interest in using novel wireless solutions — such as TV white space (TVWS), satellites, drones,
and free space optics — to unfetter rural areas from the
encumbering constraints of infrastructure (traditionally associated with broadband Internet provisioning). The
aim of this Feature Topic (FT) is to highlight the research
being done on leveraging wireless technologies for development (W4D), and thereby increase the quality of life
for a larger segment of human society by providing opportunities to connect resources and capacity, especially by
provisioning affordable universal Internet access. This FT
is especially timely since it coincides with the recent push
by various companies (e.g., Facebook/Internet.org) and
organizations (e.g., the Global Access to the Internet for
All [GAIA] research group at the Internet Research Task
Force [IRTF]) for the vision of global access to the Internet
for all.
Overall, 16 papers were submitted to our FT, out of
which we have selected four high-quality articles. These articles, written by researchers from leading groups around the
world, have been selected after a rigorous peer review process, and present a broad snapshot of the W4D work going
on in the broader ICT for development (ICTD) community.
A salient feature of all the selected articles is that they pres-

ent insights developed from real-world field deployments. A
brief description of the accepted articles follows.
The first article of this FT is “Research Advances on
Wireless Community Networks with the Community-Lab
Testbed,” authored by Leandro Navarro along with contributors from Community-Lab. This article present insights the
authors have developed through managing the Community-Lab (Community-Lab.net) wireless community networking testbed, which comprises more than 200 hosts and is
built on top of a federation of existing community IP networks constituted by more than 40,000 routers and 60,000
km of links.
The second article accepted for this FT is “Toward
Enabling Broadband for a Billion Plus Population with TV
White Space” authored by Kumar et al., which proposes
TVWS as a robust and affordable backhaul solution to
reach a billion plus population of users within India. In particular, the proposed solution uses TVWS for the “middle
mile” that connects the last mile (local Wi-Fi clusters) with
an optical fiber backbone. In this article, the authors articulate the insights they have developed by commissioning a
real-life TVWS testbed that covers more than 13 villages in
rural India (spanning an area of 25 km2).
The third article accepted in this FT is “Wireless Technologies for Isolated Rural Communities in Developing
Countries Based on 3G small-Cell Deployments.” This article, authored by members of the EU-funded TUCAN3G
project, discusses the technical and socio-economic factors
related to mobile voice and data service provisioning in
isolated rural areas of developing countries. The authors
propose a small-cell-based 3G solution that uses 3G femtocells for the access network along with heterogeneous backhauling. The authors evaluate their solution using a pilot
deployment in the Peruvian jungle and demonstrate that the
proposed solution is long-term sustainable.
Finally, the fourth article selected for this FT is “SmartCell: Small-Scale Mobile Congestion Awareness” authored
by Schmitt et al. In this work, the authors provide an insightful look at the cellular quality divide through an observa-

tional study based in three different settings, including San
Cristóbal Verapaz, Guatemala; the Za’atari refugee camp
in Jordan; and Santa Barbara, California. Based on their
findings, the authors propose SmartCell, an Android-based
quality of service application that can detect congestion
on a cellular base station and improve mobile connectivity by automatically switching in real time between networks (when multi-SIM handsets are available) or through
user-initiated manual switching between networks (when
single-SIM handsets are assumed).
We hope that the networking community benefits from
the insights presented in this FT and that it provides a balanced snapshot of the range and breadth of W4D research.
We sincerely thank all the authors and reviewers for their
help and efforts. We would also like to thank the staff members and Editor-in-Chief of IEEE Communications Magazine for their guidance and help.
