This page contains information for the version of SDL models for simulating the behavior of a low rate wireless personal area network, which uses the third re-circulation IEEE 802.15 working group letter ballot draft text (D16 July-2002) as the basis.

This software was developed at the National Institute of Standards and Technology by employees of the Federal Government in the course of their official duties. Pursuant to title 17 Section 105 of the United States Code this software is not subject to copyright protection and is in the public domain. This SDL model is an experimental system. NIST assumes no responsibility whatsoever for its use by other parties, and makes no guarantees, expressed, or implied, about its quality, reliability, or any other characteristic. We would appreciate acknowledgement if the software is used.

The following files will require an SDL editing tool to read and interpret the files. These files were created using the Telelogic Tau 4.2 SDL Suite.*

For a view of the structure or layout of the SDL model contained in the files below, look at SDL Organizer View in pdf format.

System files (a compressed file using WinZip 8.0**) approximately 4 KB

Signal definition file (a source file) approximately 27 KB

Physical layer package (a compressed file using WinZip 8.0**) approximately 28 KB
