The best tool to combine with HiPath Wireless for planning, surveying and real time tracking is Ekahau Site Survey.
Current version is at v4.1 and is offering following highlights:
* 3D network planning
* Site surveys
* Network analysis, optimization and simulation
* Troubleshooting
* Automated reporting
* RTLS deployment
I have used it personally on 3 projects and I must say it works very well.
