4131 is one of the groups that's popped up on a couple occasions as a possible testing group. Those are State RID's (possibly cache RID's?). Edison would be of course be 1205xxx.
I almost wonder if they're maybe testing to see if another site is needed in the New Brunswick cell for northern Middlesex County? I mean, there have been unsubstantiated pure rumors about Edison making a switch to either the County system or the ICS.
PD that would obviously be a given, but Fire/EMS I doubt it.
I believe 4131 is in DB as REMU (my google sheet has that) I also believe that they had a few portables on loan. Yes likely cache radios with RSSI display and Site ID enabled.
Conversation eventually turned to Middlesex and that system not being ready yet for Edison (plan to add towers).
Some reference to past testing from Fire. Of course PD got totally different results.
Many unknowns as Site 8 has had improvements since first rolled out and who knows how radios are programmed for roaming. Any foliage has an impact too.
Clearly not radio techies doing testing, but good investigators for sure.
Another favorite soapbox topic. Testing system coverage with portables in the car and reporting and recording RSSI levels that way. Ughh almost like Site 21😂
My conclusion you will see Edison PD on NJICS funded with bond monies allocated and bonded for Edison’s own slow growth P25 system. I think a decision is likely soon.
