Arrangement F - Annex E

PFD limits for stations operating prior to August 1, 2011

Stations that were operating prior to August 1, 2011 and that comply with the pfd limits as described below, shall be permitted to continue operations under their current parameters.

  1. The predicted maximum power flux density (PFD) of the signal at and beyond the border, calculated using free-space propagation (taking into account any antenna discrimination in the direction of the border), does not exceed the limits specified in Tables E1 and E2.
  2. In Sharing Zone II, in recognition of special topographical conditions, the use of a modified Longley-Rice point-to-point propagation model with time and location variabilities of 10% Footnote 5, and standard 3 arc-second digitized terrain data is permitted. Footnote 6 The limit for the predicted PFD shall not exceed -107 dBW/m2 at and beyond the border.
