U-NII DFS RULE REQUIREMENTS 5.1 WORKING MODES AND REQUIRED TEST ITEMS The manufacturer shall state whether the UUT is capable of operating as a Master and/or a Client. If the UUT is capable of operating in more than one operating mode then each operating mode shall be tested separately. See tables below for the applicability of DFS requirements for each of the operational modes. Applicability of DFS requirements prior to μse a channel Requirement Operational Mode Master Client without radar detection Client with radar detection Non-Occupancy Period √ Not required √ DFS Detection Threshold √ Not required √ Channel Availability Check Tim √ Not required Not required U-NII Detection Bandwidth √ Not required √ Applicability of DFS requirements during normal operation Requirement Operational Mode Master Client without radar detection Client with radar detection DFS Detection Threshol √ Not required √ Channel Closing Transmission Time √ √ √ Channel Move Tim √ √ √ U-NII Detection Bandwidth √ Not required √ Additional requirements for devices wit…
