RF Propagation Modeling

Coverage modeled in EDX Wireless and validated in the field — because coverage is not a map exercise and the failure mode is a radio that does not reach anybody.

Also known as EDX Wireless, SignalPro, Multipath Analysis

Left to right is time. Each row is one of the 13 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.

Propagation, coverage and multipath analysis across land mobile radio, fixed wireless and point-to-point links, modeled in EDX Wireless (SignalPro) and validated by field testing.

Coverage is not a map exercise. Reflections off buildings, terrain and water put nulls exactly where a responder does not expect one, and the failure mode is a firefighter inside a structure whose radio does not reach anybody.

Also ran the preliminary RF engineering on the Cisco-partnered mesh pilot personally — antenna gain, mount height, omnidirectional pattern and a two-mile service radius, modeled on received power at the best base from the remote with noise and predicted interference included rather than a clean-sheet coverage circle.
