New NC Corrections NXDN systems?

[troymail]

Three new licenses this week for trunked NXDN systems around the state...

NASH: ULS License - Public Safety Pool, Trunked License - WRBZ975 - NORTH CAROLINA, STATE OF

HARNETT: ULS License - Public Safety Pool, Trunked License - WRBZ976 - NORTH CAROLINA, STATE OF

BUNN: ULS License - Public Safety Pool, Trunked License - WRBZ977 - NC DEPT OF PUBLIC SAFTEY RADIO COMM

I saw that in the weekly update as well.

So much for interoperability, even among state users/agencies. Let’s not forget the plethora of NCDOC VIPER TGs available as well.

IMHO, if new radios were a need, then perhaps APX4000s could’ve considered and utilizing some of the 700/800 MHz simplex freqs while on a given prison camp?

Because why should the government ever try to save money.

had a guy that works in a local prison try to tell me that the 800MHz radios wouldnt penetrate the walls inside the prison. needless to say theres a local tower within a mile or 2 of the prison. yet they can use low powered VHF radio systems around the prison...

Yep. I’m sure others exist but head over to the NC Database and take a view at the Nash Co and. Asheboro DOT VIPER towers.

So much for the reliability of a random guy who works for a local prison knowing very much about RF engineering.

The Harnett prison moved to NXDN (Nexedge).

 

[theoldcop]

New Hanover County Jail NEXEDGE:
154.665 - Primary
155.260 - Spervisors
Although I know for a fact that these frequencies are correct, I’ve not yet been able to monitor them. Might be simplex.

Take the MSRP of APX4000's, times the number of radios in the DOC prisons, (approx. 18,0000 radios) and what do you have? A very very big number, for just radios. Not even starting to think about about penetration of VIPER into all DPS prison buildings, or coverage in the extremely rural areas of some of the facilities. Or a bunch o' other questions that enter into the decision.

Or you upgrade all existing systems to NXDN for maybe $7 million, give or take a little.

Interoperability barely moves the needle of the care-meter in this discussion.

BTW, I hate the word 'plethora'

So your saying the plethora of current radios in state DOC is NXDN upgrade capable? Wouldn't require a plethora of cash to upgrade to a Kenwood NX radio? Then why not stay with what the state can handle from the VIPER level?

No. I'm not saying that. You may be inferring I'm saying that, but you're errr, mistaken. The current crop of radios in state DOC is simply the current crop of radios within the DOC. I'm not at all saying they're NXDN upgrade capable.

Upgrading all the DOC radios to NXDN will require a large amount of cash.

But changing to APX4000's for use by everyone in all the DOC facilities (remember, I said about 18,000 radios) will require a substatially larger amount of cash, based on the MSRP of an APX4000. And that does not even consider coverage of the VIPER system into and out of the facilities; whether VIPER can penetrate deep into concrete and steel buildings, or provide coverage to some of the rural operations.

I'm sure there could be a way to figure out how far VIPER towers are from prisons. Certainly not in my cards to do, esp. after 11:00 PM. I've got other more important things to do.

How many TG's does DOC have on the VIPER System? Will that be enough to support all their operations?

Lots of other questions....

kinda like the woman seinfield was dating. Deloris.

Makes one uneasy. sounds...anatomical...

Yeah, like the word 'moist' sends some people around the bend.

Two other prisons just got NXDN/P25 UHF Licenses granted

[overtheair]

To add on to what kb4mdz stated on p25 penetration, When I was at the Durham County Sheriff's Office, if a deputy went to FCI Butner, they would lose service the moment they walked into the door. The closest tower on that system is 4-5 miles, give or take(line of site) away. I can not say now days, Marshall could possibly answer that question.

I'm waiting on all these Viper Tags to become active i.e. state parks /prisons etc. it must be a money thing

 

[RaleighGuy]

Got my first (all be it very short) hit on the Raleigh Central Prison NXDN96 system, while doing a spectrum search near the downtown area it popped up. Using RAN 1 on freq 453.050 (license WRDB309) someone calling "Officer" so and so in clear.

It sounds like I'm only hearing one side of the conversation, and only one frequency. Also not logging any talk groups, or talkgroup 0. Receiveng traffic on both systems I entered (NXDN(c) and NXDN(d), which just have to do with formating of RID and TGID. Logs from overnight are attached.

A visit to across the street from the prison allowed me to hear both sides of the conversation, however I'm not seeing any Talkgroup information, since it's programed as a wildcard all its saying is wildcard, no associated TG number. As this is in testing stage maybe they aren't running on a trunked system yet, just single channel.

Anyone have any thoughts on this?

It's possible those using nxdn have a NX 5200 with nxdn, p25 and trunking enabled. They may be interoperable but other agencies may have issue unless dispatch is provided with hardware to monitor them and relay or a patch is made on a p25 tg from the nxdn. Seen it occur other places before.
