A facilities crew asks why a 2.4 GHz signal can often travel farther than a higher-band signal in free-space discussion. Which relationship should the technician emphasize?
Select an answer to reveal the explanation.
Short Explanation
Think of ocean swells versus tiny ripples. Lower frequency means longer waves, and those long waves usually hang on better over distance in the free-space story. Higher bands are not broken — they just ride shorter wavelengths with different range tradeoffs.
Full Explanation
Frequency and wavelength are inversely related for RF propagating at the speed of light: higher frequency yields shorter wavelength. At technician depth, longer-wavelength signals in the 2.4 GHz class are often discussed as propagating farther in free space than higher-band signals under comparable conditions. That does not mean higher bands are defective, nor that wavelength equals configured channel bandwidth. Coverage still depends on power, antennas, obstacles, and design — but the property under test is the frequency–wavelength relationship.
