Puting some one down for there spelling ETC. is just small of you... given the fact that you took the time to figure out what they where saying.
First off, the FCC mandated that all users below 512 mhz narrow band by midnight Dec 31 2012.
This does not mean that anyone has to go digital or go to trunking, just change the frequency band with.
Now, the IWN project was started back in 2004, when the FED's and Canadian Gov't started looking at better ways to talk to each other and in prep for the 2010 Olympic's.
The IWN system has many relay locations along the US/Candain border and IS NOT a normal repeater system as has been described, it is a microwave system take carriers use to past data and voice information for location to location.
This system has since been expanded to cover over 90% of the state of washington and is used by all the feds, canada and some local goverments.
Now then comes the feds and they tell the state that since the IWN back bone is in place, why do you not save money and come on board the system instead of spending big $$ to build out more of your own sites.
After a lot of reserch on the current locations of the IWN sites vs the locations needed for WSP, it was found that this is a VERY good move, as in the long run only a very small number of sites would have to be added.
What this means is, not only can the WSP but also the DOT, DNR, and other state agency's can now pick up a radio and be able to talk to any one any where within the state or to other agency's that are tyied into the system to include any local goverment. (read police,fire). and all agency's to pass data,
(read, license checks)
The WSP is going to narrow band ONLY, no encription and yes there are going to change out equipment in the mobiles and portables to a radio that will allow for the ablity to change channels and talk directly to the local police even thru they are using 800 trunking.
No major frequency changes other then narrow banding is being planned.
As for the trunking, the way that the WSP operates state wide, trunking is NOT a useable item as trunking as a whole will not work over a very large area, (read over about a 50 mile radius), so this
IS NOT a option for the patrol.
Yes, the WSP is also thinking that when they go narrow band, that they will go to the digital audio format as the digial will allow for the passing of data more efficently.
There is some of this new equpment already in use up north of Everett since 2009 and has been working great and has allowed the WSP to talk directly to FEDS and canada.
Just saying I always like your incite
LOL BrettThanks Ken, a good riot is hard to come by.
This is a real interesting thread. I'd like to add a couple of comments.
Statewide trunked systems can work.
Wyoming, with its mountainous terrain chose VHF P25 trunking when they built their WyoLink system.
Utah, is slowly building an 800 MHz system. Starting with the areas of the 2002 Winter Olympics, and now adding more & more rural sites.
Imagine being in Everett and listening to a search for a downed aircraft near Wenatchee. I Live in Salt Lake, and I heard a search for a crashed plane miles east of the Wasatch Mountains.
Well, enough of my $.25.
