Mathematical signal array, wireless antenna, parabolic grid directional antenna, radio wavelets, on a grid of sky spirals.

Communication towers or base stations are installed and positioned in grid patterns across geographic areas -- cities, rural environments -- so their signal reach overlap and communications can remain seamless as the signals emitted by cell phones/digital devices in use as people travel are picked up as they pass within range of the towers.
