Wireless networking
These
materials were developed as part of the Capacity building for community wireless
connectivity in Africa initiative which was funded by IDRC and coordinated by APC.Training units Network
planning, WiMax and non standard solutions,
Energy for telecommunications systems, VoIP, Long distance wireless
link, Community, gender and technology and Sustainability strategies were
developed between 2007 and 2008 as part of the project TRICALCAR
which was funded by ICA
and coordinated by Wilac.net.
This is the
second public release of the materials, which have undergone undergoing
revision over the course of a pilot workshop series of both above
mentioned projects.
The materials
assume a good understanding of TCP/IP networking and some experience as
a network administrator. See the
ItrainOnline Wireless section for links to further resources
on wireless networking.

Unit overview: This unit starts by
giving the reader a brief overview of the concept “Link Budget” in
order to provide a clear picture of when, where and why the choice of
antennas and cables matters in wireless implementations.
Thereafter, the unit covers antennas in terms of types of antennas,
polarization, isolation and finally, the unit discusses coaxial cables
and connectors.

Unit overview: This unit serves as an
introduction to the software “Radio Mobile”, a radio simulation tool
for outdoor environments. The focus of this unit should be on the
understanding of the different building blocks of the software. Rather
than understanding how to simulate one specific type of wireless
infrastructure. the learner should be able to apply the methodology to
any kind of wireless system.

Unit overview: This document
focuses on the practical implementation of a wireless network in terms
of project planning, and budgeting for equipment. A detailed
implementation plan of a wireless network is necessary to be able to
produce a good and consistent budget. A good implementation plan should
not just consider the physical location of the wireless equipment, or
our chosen technology and vendor, but also which are the extra
resources needed to get a network up and running.

Unit
overview: In the last few years WiMAX has been promoted as
the wireless broadband future standard. Many Internet wireless
providers (WISP) and governmental institutions are
considering migrating IEEE 802.11-based solutions
and investment to WiMAX technologies. The first challenge to address is
the objective evaluation of WiMAX proposals and costs. The question
frequently asked is whether WiMAX is a technology à la mode or a true
realistic option for broadband wireless service.

systems that take into consideration the information and resources
available in the region.
