Which frequency band typically provides better range indoors?

The 2.4 GHz band is known for providing better indoor range compared to higher frequency bands like 5 GHz and 6 GHz. This is primarily due to its longer wavelength, which allows signals to penetrate walls and obstacles more effectively. As the frequency increases, the potential for signal attenuation also increases, meaning higher frequencies have a harder time traveling through physical barriers like walls and furniture.

In addition, the 2.4 GHz band is less prone to specific types of interference that affect the higher bands, although it can still be congested due to many devices operating within this frequency range, such as microwaves, Bluetooth devices, and other Wi-Fi networks. However, despite this potential congestion, the inherent properties of the 2.4 GHz frequency allow it to maintain better overall range indoors.

In contrast, the 5 GHz and 6 GHz bands are typically favored for their higher speeds and lower potential for interference from non-Wi-Fi devices but are less capable of delivering signal strength at greater distances or through obstacles. The 1.2 GHz band, while less commonly referenced in consumer applications, is also not standard for typical wireless data communication as it is in a different context, further confining its relevance to this question.
