Project 25 Trunked Radio

The Motorola P25 platform the regional system was ultimately replaced on, carrying a 10,500-radio fleet.

Also known as P25, Project 25, Motorola P25

Left to right is time. Each row is one of the 4 disciplines this one worked alongside, ordered so kindred disciplines sit next to each other rather than alphabetically — a landscape only means anything if neighboring rows belong together. Height is the work running in that domain in that year, weighted by what failure would have cost — life-safety ×3, a statutory obligation ×2.2, the estate itself ×1.5, an evaluation ×1. Every project declares which of those it was, so each ridge traces to an entry you can open and disagree with. Only the work that used this technology is counted, so what shows here is the company it kept rather than the record around it. Height and color are on the record-wide scale rather than this page’s own, so a modest estate draws a modest landscape and any two of these pages can be read against each other.

P25 trunked radio as the target platform for the First Coast Radio System replacement: master site relocation, a backup site, multiprotocol capability and site expansion, carrying a fleet of roughly 10,500 subscriber radios.

P25 also came forward through the courthouse DAS refresh, which carried public safety 800 MHz as digital P25 rather than the analog signal the original system had distributed.
