The six site simulcast analog type is certainly consistent with emergency services paging use. Our county (Broome) set up a similar system on 159.105 for paging all emergency services. Dispatch channel communications are no longer interrupted by tone outs and pagers receive messages everywhere in the county rather then just in their local area. I believe Morris County has a similar system on 476.2875 for paging. The only thing that puzzles me about the Bergen County application is that the application includes 700 mobiles. The Broome and Morris County licenses do not include any mobiles.
The county has been simulcasting paging to several towns on TG 91 on the system. Palisades Park, Wyckoff and Midland Park have pages coming over that tg at the same time they are dispatched on analog. With Unication pagers capable of P25 paging, it seems odd to have a conventional UHF freq. Then again Its most likely costly for towns to buy a Unication G5 pager for every member.
TO add to this
155.550 license also updated with P25, however
Westchester Co has been testing for the past few weeks - Alpine site looks over westchester
as was told to me 40 years ago Bergen had Westchester to change freq or lower power or down tilt because they ere interfering operations on 155.55 which had various County units operating on simplex and repeat
