Perl Scripts / Interactive Design / Software

Interactive Wireless Network Design Analysis Utilities

The following CGI scripts will help you model your wireless network. The outcome is only theoretical, and assumes no drastic environmental factors, and controlled conditions. (No temperature inversions or large objects blocking the path)
