On the Maryland Eastern Shore, a tri-county consortium continues to keep alive their legacy Smartzone system even though public safety and some local government agencies migrated to the state's P25P2 system several years ago. One of the justifications for moving to the state's system were EOL issues for SmartZone equipment, yet one of the member counties has allocated $24M to keep it alive as a back up (unclear if they are actually spending those funds.) Part of motivation is Eastern Shore politics - aka distrust of the state government - but it would work as a limited backup scheme as the subscribers do have SmartZone options installed. In Maryland, there is no charge to use the statewide infrastructure, but jurisdictions have to purchase subscribers and whatever equipment necessary to link their ECCs to the system - and pay for additional channel resources and sites if required.Concur. The high cost of simply keeping it running, much less fixing what breaks, means it's fiscally unsound to keep the old system running.
I briefly thought about keeping our old system running in a scaled-down form as a backup. . . briefly. It was mainly a pipe dream, especially after I worked the numbers.
