Coverage and channel count move with cell count, pitch, and layers. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.
highlighted = computed this step
Compact grid closes coverage
Cell count 4 with pitch 2 m gives total length 8 m. Layer count 2 gives channels 8.
L=4×2=8,C=2×4=8
More cells raise channel count
Cell count 6 with pitch 1 m gives total length 6 m. Layer count 2 gives channels 12.
L=6×1=6,C=2×6=12
Wider pitch raises total length
Cell count 5 with pitch 3 m gives total length 15 m. Layer count 3 gives channels 15.
