Visual Representation of Signal Coverage
A wifi amplifier improves signal coverage by extending the range of your router’s signal. Imagine your router’s signal as a circle emanating from its location. Without an amplifier, the signal strength weakens as you move further from the router, creating dead zones. An amplifier placed strategically in a weaker area essentially creates a second, overlapping circle of signal, effectively extending the overall coverage area and reducing or eliminating dead zones.
In a typical home layout (e.g., a two-story house), the router might be placed on the first floor. Without an amplifier, the signal might be weak or non-existent in the far corners of the first floor and most of the second floor. By strategically placing an amplifier on the second floor, or midway between the router and a distant area, the amplifier’s signal overlaps with the router’s signal, improving coverage throughout the house.
Consider a textual representation: ‘R’ represents the router, ‘A’ represents the amplifier, and ‘.’ represents areas with weak or no signal.
Before Amplifier:
R…..
