When talking about TDWR interference...

There was also an issue with devices that employed frame based architectures that allowed operators to
reconfigure the talk/listen ratio of their devices.

Could someone shed some light on what they're talking about?


Below is a summary of what I saw. I say certain things will happen, but it's a mix of things they want and things they want comment on. None of it is set in stone.

  1. U-NII -3 will be extended 25 MHz to match the allocation to ISM devices.
  2. ISM will be removed from our use.
  3. U-NII-3 will lose the power limit based on channel size and will just be 1 watt.
  4. Currently there is no EIRP limit in ISM, but there is in U-NII-3. U-NII-3 requires a 1 db reduction in transmitter power for every dB of antenna gain over 23. The U-NII-3 rules will carry forward, restricting transmitter power into large dishes.
  5. U-NII-1 power limits may be increased to match U-NII-2, outdoor operation permitted, power limits may be increased to match U-NII-3.
  6. Something people seem to forget a lot, "We note that, while the TDWRs have been the focus of Commission investigations, DFS was designed to protect all incumbent radar operations and modification of devices as described above poses a risk of interference to more than just TDWRs".
  7. The Commission, NTIA, and the FAA have been working with manufacturers of U-NII devices and the WISPA to fully understand the causes of interference to TDWR systems and to identify ways to mitigate and significantly reduce the likelihood of interference. The Commission believes the rules proposed herein, in addition to continuing enforcement efforts, will enable us to achieve this goal while allowing U-NII devices to continue to operate successfully in the 5 GHz band.
    :sunglasses: Bunch of stuff about how to limit the ability to run over-power in restricted bands.
  8. Possible geo-location database for U-NII.
  9. As noted above, a voluntary database has been implemented by WISPA, which disseminates the location of TDWR to WISPs and encourages operators that install devices within 35 km or the line-of-sight of a TDWR, to operate at least 30 megahertz away from the TDWR operation frequencies. WISPA has also agreed to voluntarily provide a database where WISPs can register the locations of the outdoor transmitters that they use.
  10. Possible TDWR sensing.
  11. Bunch of stuff about changes to the certification process.
  12. Similar power rules for U-NII-2B as U-NII-2A and C.
  13. Similar power rules for U-NII-4 as U-NII-3.
  14. Both new bands may have DFS, database, etc.
  15. Manufacturers have 12 months from the effective date of new rules to make modifications for the new rules and get certified.
  16. Old gear can be installed 24 months after the rule change.
  17. Existing gear is grandfathered for the life of the equipment.

I'm sure I missed some stuff. If it looked boring or started having a bunch of formulas in it, I skipped it. I'm sure I interpreted some things wrong. Deal with it. :-p
