>>One .16 member indicated to me that the reference to "primary

>>the 5 GHz unlicensed bands ... if this is the intent, clarification
>>in the scope to that effect would mitigate our concerns.

>>Additionally, section 16

>>802.22 PAR and a statement that the 802.16h PAR would not conflict
>>with our scope would be appropriate.
