Well Riverside County bought the Motorola's version of the X2-TDMA Kool-Aid and didn't probably think things through.
Actually, nothing could be further from the truth.
The needs assessment was a process that took several years and was extremely detailed. Writing the bid specification was a lengthy and detailed process as well.
The "X2-TDMA" is what manufacturers are selling in a system of this size and complexity, so no one really has to "buy the Kool-Aid". To specify anything less in the RFP is to go in with a system that is automatically obsolete, and soon to be incompatible with the rest of the region. Compatibility was a major issue for Riverside County, because it was an EDACS island surrounded by Motorola systems.
You have to remember that Riverside County is bigger than some states in our country...
As a native Californian and involved in the public safety "industry" here for over 35 years, I've become quite well acquainted with the size, demographics, politics, and radio systems in the region.
This one is going to be especially interesting to watch because of the careful attention to detail that's been paid to this project. I see two major pitfalls looming...
The first is that P25 Phase II is a fairly recent technology that hasn't fully matured. It's going to have bugs in a mass build-out, like Riverside County is doing... no question about it.
The second pitfall is going to be matching customer expectations with the reality. RSO jumped onto the Motorola bandwagon because it's not EDACS, and therefor must be better. They started with the perception that just because it's Motorola, the RF will get out better, the radios will sound better, and the system will never crash.
The reality will be that there will STILL be some dead spots (just not as many), P25 Phase II audio sounds like crap to many people, and in a system as large and complex as this one is, there WILL be failures, and major ones. Especially at first.
...and its going to cost a boat load of money that the county nor surrounding cities have to probably get this system up and running at full capacity. Millions and Millions of dollars. Aint no chump change
Unfortunately, I don't think there's any way around that. The sheer size of the coverage requirements there dictate a massive build-out in sites. There were some unrealistic expectations for coverage and grade of service in some very remote desert areas that needlessly run up the cost, but RSO is a pretty hard headed customer when it comes to that. A number of incidents, including the two deputies killed in Cabazon in the late 90's made them hyper-sensitive about their radios. Cabazon was a marginal coverage area at the time and, even though it wasn't really a factor in that tragedy, the perception is that it was.
