Abstract

A goal of indoor wireless communication is to strategically place RF base stations
to obtain optimum signal coverage at the lowest cost and power. Traditionally,
transceiver locations have been selected by human experts who rely on experience and
heuristics to obtain a near-optimum placement. Current methods depend on involved on-site
communication measurements and crude statistical modeling of the obtained data
which is time consuming and prohibitive in cost. Given the inherent variability of the
indoor environment, such a method often yields poor efficiency. As an example, it is
possible that more power than required or extra number of transceivers were used. This
thesis describes an interactive software system that can be used to aid transceiver
placement. The tool is easy to use and is targeted at users who are not experts in wireless
communication system design. Once the transceiver locations are selected by the user
within a graphical floor plan, the system uses simple path-loss models to predict coverage
regions for each transceiver. The coverage regions are highlighted to indicate expected
coverage. Earlier work assumed isotropic transceivers and had limited directional
transmitter support. This thesis describes how the tool has been enhanced to support a
wide range of 3D antenna patterns as encountered in practical situations. The tool has
also been expanded to accommodate more partition types and to report area of coverage.
The resulting system is expected to be very useful in the practical deployment of indoor
wireless systems.
