>> For example, If you are on 866.0125 now, your rebanded channel will be 851.0125. This is the case for all of the 866 - 869 frequencies.
Hi, QBall. I haven't seen the following questions posted / covered on RR or the other forums. Would you know:
a - If an agency is rebanded from the NPSPAC frequencies, are they also required to move to a narrower bandwidth since another local licensee may be +/- 12.5 kHz of their new frequencies ?
b - If a public safety licensee rebands into the 851-854 segment, and experiences interference from an SMR who has not rebanded out of those frequencies, who has the primary responsibility to solve that interference issue ?
c - I was under the impression that, during the rebanding process, there should normally be a time period when an agency's TRS license(s) would reflect both the "old" and "new" frequencies. Correct or incorrect ?
Thanks, QBall.
Jeff, Sorry I haven't aswered you sooner. I went out of town right after I made the post and haven't done a whole lot on RR since I got back. But, Let me see if I can answer your questions.
A - NPSPAC 866 - 869.995MHz channels already operate at a more narrow bandwidth than other 800MHz channels....they operate at 20KHz and that will not change once they reband.
B - 851 - 854 is being cleared for public safety just as the 866 - 869 are public safety only today. There may be some issue near Georgia with the SouthernLinc system, but I have tried to avoid that portion of this mind bobling event. Generally speaking, the rebanded channel that you get will have the same cochannel and adjacent channel users as you have today. It is supposed to be a "no-impact" and ultimately status quo situation. To answer your question, it is incumbent upon NEXTEL to make sure that you have equal coverage and no additional interference from other sources when you change channels.
C - Yes, for some period of time, you will hold channels in the 866 - 869MHz and 851 - 854MHz range. The old frequencies will go away once rebanding is complete. In example, some jusrisdictions may choose to run ITAC1 and ITAC1R simultaneously for some period of time. In a case that I have heard about, current and rebanded channels may run for a period of a year or 2 so as to have complete interoperability for the duration of rebanding.
Lastly, I hear that there may be a move to change the NPSPAC mutual aid channel naming standard to the NPSTIC (npstic.org) channel naming standard. This would mean that ICALL would be 8CALL90. ITAC1 would become 8TAC91 and so on. Check it out.
Please let me know if you have any other questions. By the way, I "gave at the office" the other day and thought that I may see you around. Sorry I missed you.
