The First Responder Network Authority (FirstNet) has released the fourth and last  batch of answers to questions concerning the draft request for proposals (RFP) and special notice it released in April (TRDaily, April 27).  Today’s tranche included answers to about 150 questions. In all, FirstNet received 670 questions from 52 entities about the draft RFP and special notice, including in writing and during an industry day held in May (TRDaily, May 14). There were a total of 666 answers released, as there were a few duplicate questions or statements or comments rather than questions.
