Problems solved by technology

There are many field strength prediction models for radio wave propagation. Most of these models are based on a large number of on-site measured data in different regions and terrain conditions in various countries and are obtained through numerical statistics. They have obvious limitations and deficiencies. Due to The actual measurement area is limited and the amount of actual measurement data obtained is insufficient, resulting in low prediction accuracy and large differences between the effect and the actual situation, which seriously affect the use and construction of the project
