The mobile phone signal is not good, it may be that the weather is too hot!

Hunan continues to have high temperatures, with more than 40 degrees in some areas. High temperature not only affects outdoor activities and labor, but also affects mobile phone signals.

On August 16th, Xie Zhanpeng, Hunan Mobile Network Excellent Center, said in an interview with Xiaoxiang Morning News reporters that the high temperature weather continued, the atmospheric waveguide increased, and the mobile phone signal may be affected by interference.

Atmospheric waveguide is an unusual atmospheric structure, which mainly affects the spread path and range of electromagnetic waves in the atmosphere, leading to some special communication features such as communication, detection, and navigation. The atmospheric waveguide is mainly caused by the temperature of the atmosphere (the temperature increases with the height) and the inverse wetness (the water vapor density decreases rapidly with the height increase). During this time, due to the high pressure of the subtropical, the high temperature continued, resulting in the large humidity of the near -ground layer, and the middle and high -levels were dry, which was easy to form against wet wetting. At the same time, it was prone to reverse temperature layers at night. "Atmospheric waves have formed a catheter that is suitable for wireless signals on the ground and atmosphere. Signals in far away can reach the signal of nearly interference through the catheter." Xie Zhanpeng said that the wireless signal has a small loss in the atmospheric waveguide, and the base station is the base station. The signal was sent out. After the high remote downward transmission of hundreds of kilometers through the atmospheric waveguide, it fell into the upward receiving window of the proximal base station, causing upward interference. Hunan generally appears in the months around summer and autumn, and the interference is relatively heavy, and it is more obvious from 11pm to 7 am. From the perspective of the Internet, the indicators of disturbing communities are worse. For users, the most direct feeling is that the speed of the Internet is not good and the call is not clear.

Hunan is mainly affected by Huandong Tinghu area. The area is relatively flat and has a large area of ​​water. The atmospheric waveguide effect is stronger. The province's Changde, Yiyang, Yueyang, Changsha, and the base station signal near the Dongting Lake area in Hubei may form a formation of the base station signal may form. Interfering with each other, as many as hundreds of base stations. Relatively speaking, mountains and hilly areas such as western Hunan and South Hunan have less atmospheric waveguide interference.

Xie Zhanpeng said that the mobile users of Hunan Province are affected by 4G network users, and 5G users are not affected. For atmospheric waveguide interference, interference needs to be found through daily monitoring, and then responding to measures to reduce the impact in time. It mainly modifys the special sub -frame ratio to make useful signals and interference signals staggered in time. There are a group of engineers in Hunan Mobile to centrally monitor and dispose of the province's atmospheric waveguide interference. Usually, it is found that the interference can be adjusted within 1 hour, which can minimize the impact on users.
