What is a consequence of the shorter wavelengths at 5GHz compared to 2.4GHz?

• A. 5 GHz waves have a higher indoor range
• B. 5 GHz waves penetrate walls better
• C. 5 GHz waves have a lower indoor range
• D. 5 GHz waves are faster

Answer: (C)

Shorter wavelengths, like those used at 5 GHz compared to the longer wavelengths at 2.4 GHz, result in reduced indoor range. This phenomenon occurs because higher frequency signals, such as those at 5 GHz, experience greater attenuation as they encounter obstacles, including walls and furniture. As a result, 5 GHz signals are less capable of maintaining strength over distance and tend to degrade more quickly than 2.4 GHz signals when navigating through various materials. In essence, while 5 GHz may support higher data rates and faster speeds due to wider channels, this advantage comes at the cost of range. Therefore, the statement regarding the lower indoor range of 5 GHz is accurate, as the signal's inability to penetrate and travel effectively through obstacles results in a shorter effective coverage area within buildings.
