2027 Agenda

Land Mobile Radio (LMR) system design is often captured as an assortment of documents - spreadsheets, diagrams, PDF documents, etc. These design artifacts provide a snapshot view of a system but often arrive stale and only become more stale with time. Consistency has to be manually verified between documents, and as a system evolves with maintenance, expansion, and lifecycle replacements, keeping an accurate global system design repository becomes a full time effort. More likely, it becomes an exercise in change management that lives in engineers' and technicians' minds and gets manually verified at strategic points or when failures occur.

In this session, apply a model-based approach to design capture that enhances design review and pulls design questions and implications into operations and incident management. Drawing from the Systems Engineering (SE) community's push toward modeling, see how models provide a computationally-enabled approach to design that can incorporate verification that brings rigor and context to the project and decreases risk for project implementation.

Models can be used to check for a variety of things, from network capacity and latency bottlenecks across a large statewide network to power loading analysis on a site expansion to naming conventions for switch ports required by a system owner. Once a design has been checked and implemented, the same models can serve operations by capturing changes and providing additional analysis to the system as it grows and evolves.
