Any thoughts as to what the new system might be?

Maybe a P25 system, which could be immediately interoperable with the N-WIN and Douglas/Washington/Pottawattamie/OPPD systems farther to the east?

Hummm....

N win would be nice. Most likely sound a lot clear than the one there on now.

Downtown is just a dead zone

I bet it's going to Harris 800mhz P25 simulcast. I don't believe Harris supports EDACS anymore and RACOM is migrating to P25. Some of the radios they have now might do P25.

For them to upgrade, wouldn't the cheapest route be getting new radio's for N-WIN 150mhz vs getting New 800mhz radio's and upgrading the towers? Also LSO, LFR, Hospitals, Schools, PW, etc is on the same system. I see it costing more in the end for everyone to upgrade to the 800.

PS. hope it is not simulcast.... unless they have a good scanner out now!

They probably have radios that are P25 800Mhz capable. M/A Com (Now Harris) did manufacture radios that could do EDACS, Provoice and P25.

N-WIN, as it is now, would not be able to handle the amount of radio traffic Lincoln/Lancaster County has. Plus a VHF trunking system is not ideal for an urban area. Also they probably could get a deal from Harris to upgrade their equipment to P25. Yes it probably will be simulcast.

A little bird said they are in the shopping stage and might be looking at a Motorola P-25 system 700/800 Mhz.

when will this be all said and done?

 

[nzo012]

I would guess years, There is consulting, deciding, funding, implementing, all yet to do. It is a pretty huge task.

 

[nzo012]

As far as the radio/system switch, I was informed that it will be sooner than later. Whatever that means. It is sounding like maybe 2 years. Nothing is for sure though.

 

[Kingmobileaudio]

But they are switching over to Narrow band by the end of the year right?

Narrow band only affect 150 to 470. They had to reband their system a couple years ago.

Oh okay so rural fire paging system

Rural fire just upgraded a few years ago so they could inter operate with all the services on 800Mhz. Needless to say they are unhappy to hear all of Lancaster County is looking to go digital just after they already spent all their money.

Time will tell what rural fire will do, but I wouldn't hold my breath for them to change, unless the money fairy visits them.

I agree and was thinking the same thing.

The only radios I see them needing to change would be the ones in the squads... Well the one in the back so they can communicating with the Hospitals.

The one in the back are programmed with Lincoln's EDACS

Why do you make the statement that VHF trunking is not ideal for an Urban area? Not sure what your basing that stand on. Please elaborate to the group why your saying that.

For starters, RFI noise in the VHF range is somewhat higher in urban areas (but RFI noise is bad overall in urban areas). Although it wouldn't be a final factor in ruling out using VHF trunking, noise is one factor that may prevent it. Economically, it would be cheaper, less towers, infastructure, etc..

Also lincoln has 20 channels on 800, where are you going to find 40 VHF channels? 40 channels due to VHF has no standard input/output pairs.

Irv 43 is also correct on noise floor even in rural area there is still issue.

Agree. VHF has a higher noise floor in the country now try to imagine that in a city. In addition VHF is not well suited to high density systems due to the size of the combiners. The non standard pairs would just be a nightmare to tune.

 

[nzo012]

A couple of months ago I would have said a positive no, on them switching to VHF, but now I can't say anything for sure. I would doubt a switch off of 800mHz, but right now there are a few big "maybes?" floating around.
