PlaceTool is a Windows
software for optimum placement of antennas in an indoor environment.
The software can be used to define the minimum number of base stations
needed to provide complete coverage of an indoor area by optimum placement
of the antennas. The software uses building specific data such as
floorplans with wall locations and compositions and system parameters such
as minimum received power thresholds and antenna patterns.
The propagation
mechanisms used in the software are based on the extensive research work
at CWINS in modeling of the indoor radio channel, and include both statistical
models and ray tracing techniques.
Below, a sample
screen capture of the software is given for 2 base stations on the first
floor of the Atwater Kent Laboratories building at WPI. Walls can
be added, deleted or changed in the floorplan from the GUI. Once
the floorplan is complete, base stations are simply added by click of the
mouse, and base station parameters such as transmitted power, antenna orientatation
can be specified in interactive Windows boxes. In addition, custom antenna
pattern can be built and associated with the base station. For the simulation,
parameters such as received power threshold, launch angle increment (resolution
of the contour) can be specified. Upon running the channel simulator,
contours of the coverage of base stations are obtained.
