ENGINEERING LAB / SYNTHETIC SCENARIO

Frequency Assignment Planner

Explore occupied channels, guard bands and requested assignments in a deterministic synthetic frequency-planning workflow.

Synthetic demonstration. Actual frequency assignments require applicable regulatory rules, licensing data and engineering criteria.

Lowest available centre first. Changing any constraint invalidates the displayed plan. This is a greedy allocation, not a global optimization.

Technical details

Candidate centres use a 0.5 MHz raster. Occupied intervals must fit inside the selected band. Each new assignment must satisfy non-overlap, an edge-to-edge guard and minimum centre spacing against both existing and newly allocated systems. Guards protect channel pairs; they are not reserved at the outer band edges. Greedy allocation selects the lowest available centre. Conflict, guard and spacing counts describe candidate rejection reasons before allocation. No geographic reuse, licensing database, service-specific channel plan or global optimization is included.

All calculations run locally using synthetic scenarios. A real project starts with your data, agreed engineering methods and validation against known cases.
