The FCC recommends a distance of 250 feet from residences, but approvals can be granted for closer distances. It's important to note that most of the energy from cellular communication is directed away from the ground, resulting in minimal radiation exposure. In fact, radiation dissipates. Just like a house needs a strong foundation, fiber networks need these rules to ensure they last a long time and don't cause problems later. Building a network follows three key steps, and each has its own set of rules. For more accurate safety distances, on-site measurements with appropriate test meters are strongly advised. The guidelines below are the minimum.
