Cellular network signals are radio waves similar to terrestrial radio signals, and they can be affected by atmospheric conditions. Usually, atmospheric conditions have indirect effect and won’t affect signals below 2GHz and thunderstorms have direct effect. This is because of the charged electrical particles in the atmosphere interfering with the radio waves. You must have observed that when it rains or during storms the signal quality drops and sometimes results in dropped calls. So, how to improve phone signal during bad weather? Read ahead to know.
Direct And Indirect Effect
Direct effect is when the atmospheric conditions directly affect the signals, and this is because it interferes with the basic nature of these signal waves. The charged electrical particles during thunderstorms interfere with the medium in which these waves propagate, causing disruption to its transmission. Now, an indirect effect is usually caused by obstruction in the path of the signal waves. For example, during winter, when there is no foliage, the signals can transmit easily. However, during spring the trees bud and grow leaves, thereby blocking or weakening the signal by blocking the line of sight between the phone and the cellular tower.
The Effect Of Weather On Cellular Signal
The moisture in the atmosphere affects radio signals, so it can also affect cellular signal waves. This is because water is a good conductor of electricity, and this allows water vapour to reflect or refract radio waves. This phenomenon is called the “propagation delay effect” and it increases the noise of cell signal and reduces the reception.
How Different Weather Conditions Impact Cellular Signal Reception?
Rain: Rain has the greatest negative effect on cellular signal reception due to the increased atmospheric water content. The effect on signal is directly proportional to the intensity of the downpour.
Hail And Snow: Their effect is less intense than rain because ice is less dense than water and refracts the radio waves less.
Cloud And Fog: Their effect is again due to the atmospheric water content, but it is less than rain and causes localized scattering of radio waves.
Lightning: Lightning and thunderstorms affect radio signals due to electrical interference and can damage cellular towers causing disruption in local cellular service.
Temperature: The effect of temperature is not direct, but it influences the level of atmospheric humidity that has an effect on the quality of cellular signal.
Wind: The effect of wind is similar to that of temperature, and high winds cause drop in cellular signal quality.
So, the best and fool proof method to receive good cellular signal in every weather condition is to use a cell signal booster at home.
