Cells in a Network

What's intriguing about cell phone systems is their cell outline. (Thus the expressions "cell organize" and "wireless.")

The cells marginally cover at the edges to guarantee that clients dependably stay inside scope of a base station. (You don't need a dropped call when you're driving between base stations.)
