The high temperature weather in Hangzhou leads to the influence of atmospheric radio waves on mobile phone signals. What is an atmospheric waveguide?

As time goes by, summer is drawing to a close, but many places in our country have entered the high temperature weather mode, and the weather is very hot. Hangzhou, Zhejiang has the highest temperature, reaching 4 1.8℃, which has become the historical extreme value of the highest temperature recorded in recent 195 1 year. Moreover, the high temperature weather in Hangzhou has also led to the influence of atmospheric radio waves on mobile phone signals. Atmospheric waveguide is a very abnormal atmospheric structure, which mainly affects the propagation path and range of electromagnetic waves in the atmosphere, and will lead to some special propagation characteristics in communication, detection and navigation systems.

According to the Meteorological Observatory, the high-temperature red warning will continue to be released. There are about 1 1 provinces, and the highest temperature in some areas actually exceeds 40 degrees. This is also the case that the Central Meteorological Observatory issued a high-temperature red warning for four consecutive days. In Hangzhou, because of the hot weather, even the garbage classification signs on the shady side of the West Lake began to fall off by the sun. How hot is the elevator? Due to the hot weather, the cell phone signal is not good. It is because the atmospheric waveguide has an influence on communication signals, and the pronoun does not fall down, mainly because of the inverse temperature or humidity of the atmosphere, so it will have a certain influence on communication detection signals and so on.

Because Hangzhou has been affected by the subtropical high, the continuous high temperature weather also leads to a relatively high humidity at the bottom of the well, while the middle and upper layers are relatively dry, which is easy to cause a surprise of drowning, and the cooling at night also causes an inversion layer in the atmosphere. However, the atmospheric waveguide will cause relatively large uplink interference to wireless signals. Some netizens intuitively feel that the network speed is not good. Atmospheric duct liquid mainly appears in the inland suburbs at the turn of spring and summer and summer and autumn. It is nothing new that Hangzhou is disturbed by atmospheric duct, but due to extreme high temperature weather, this influence suddenly expands.

For example, some operators in Hangzhou have carried out some monitoring on the atmospheric waveguide, and they can only use the main monitoring means. When they found that it had extreme influence, they quickly adjusted a signal frequency band in the area, and then adjusted it back after the influence of the atmospheric waveguide passed. This adjustment is usually successful within one hour, and it is also to minimize the impact of high temperature weather on the indicating network.
