Which radiation is greater, the mobile phone or the landline?

Comparatively speaking, the signal radiation of mobile phone is much larger than that of landline. After all, the mobile phone is a wireless signal radiation transmission, while the fixed telephone is only the electromagnetic field radiation generated by the trace current of the cable and microphone, which is minimal.

Mobile phone radiation, the radio waves generated when a mobile phone transmits information through electromagnetic waves. Mobile phone radiation is measured by SAR value. Generally, the antenna height of GSM base stations is 35.55 meters, and the Ministry of Environmental Protection has supervised and tested thousands of base stations. The results show that the power density of the base station antenna in front of 65,438+00 meters is 0.006W/m for the base station with the transmission power of 20 watts. The radiation power of CDMA mobile phone is not less than that of GSM. The peak power of GSM mobile phone is 2W. In actual use, it only transmits at 1/8, so the maximum average power is 250mW, while CDMA is continuous transmission, and the maximum average power is about 250mW. There is not much difference between the two.

The landline also has radiation. Generally speaking, radiation is electromagnetic radiation. Strictly speaking, as long as electronic products have a certain degree of electromagnetic radiation when working. The amount of radiation and the degree of harm to people mainly depend on the working mode and power of electronic products. The radiation level of the landline is very small, and the harm to the human body is almost negligible.
