Consider the interference between different system.In some systems（Such as data radio station）In, to ensure to cover, transmitting terminal can use larger
Transmit power, can so larger interference be produced to the other systems for using similar frequency bands, the frequency range can be caused to block when serious,
For using Lin Dao（Nearby frequency bands）Or every road（Every a frequency band）System can also produce larger interference, therefore, if not
Consider different system interference, the confidence level of network plan simulation can reduce, and the guidance of network engineering construction and the network optimization is made
With can have a greatly reduced quality.
