That requirement was done several years ago to avoid military radars.

The database doesn't exist yet. Final definition and creation of it is being worked on right now by the Industry Group (Motorola, Cisco, Atheros, Intel, WISPA and others). WISPA and the FCC Committee will be helping with industry outreach and education so we will alert you (and as many other operators as possible) on-list when there are major developments and when the database is ready. Let me know which TDWR site you are near and I'll find out what frequency they are using so you can remain 30 MHz away from it. jack (Chair - WISPA FCC Committee) Eric Rogers wrote:Jack, Who do I contact to get on the list? I am like 5 miles from one of the TDWR radar sites. We are using Motorola 5.4 with 9.5 so it supposedly has more updated signatures. I would rather get on the list voluntarily than they find me.

All these enforcement actions were taken because of interference with licensed users.... Lessons I get from them... 1) Stay off the 5.4GHz band 2) Keep your EIRP down 3) Check your installations for out of band emissions. Leon D.
