900 mhz vs 2 4ghz wifi extender5/3/2023 ![]() ![]() ![]() Since the range doubles with every 6 dB of reduced path loss, the 900 MHz modules have 2.67 times as much range as the 2.4 GHz modules. Thus, the path loss is +8.519dB more over a given range for the 2.4 GHz modules. See the " Range of 9XStream (900 MHz) and 24XStream (2.4GHz) Modules" section for more detailed range information. ![]() NOTE: Path loss analysis does not account for effects such as differing TX power outputs and RX sensitivities. The table below shows how path loss differs between 900 MHz transmitters (?=0.33 meters) and the 2.4 GHz transmitters (?=0.125 meters). Where r is the distance between the transmitter and receiver, and ? is the wavelength. The path loss is derived from the Friis transmission equation and is defined as: ![]() Path loss describes this attenuation as a function of the wavelength of the operating frequency and the distance between the transmitter and receiver. As waves propagate out from the transmitter, some attenuation of the signal takes place due to properties of the medium (air in most cases). To demonstrate the basic difference in wave propagation of 900 MHz and 2.4 GHz waves, a quick look at path loss is provided. Comparing Wave Propagation of 900 MHz and 2.4 GHz Frequencies ![]()
