The main reason for using walkie talkies with frequency limitations is to ensure that the majority of users' calls are not interfered with and to make reasonable use of frequency resources.The national wireless management agency has divided the use of radio frequencies for walkie talkies,specifying corresponding frequency ranges for different industries.The purpose of doing so is to ensure orderly,efficient,and secure wireless communication.

Specifically,the function of frequency limitation includes:

1. Avoiding interference:By dividing different frequency ranges,mutual interference between different devices can be reduced,ensuring clear and stable communication.

2. Reasonable utilization of resources:Frequency resources are limited,and by limiting their usage frequency,it is possible to ensure that these valuable resources are allocated and utilized reasonably,avoiding waste.

In addition,using walkie talkies requires certain procedures,including applying for frequency points from the local radio management committee,filling out declaration forms,filing declarations,approving and paying frequency occupancy fees,etc.These measures further ensure the legitimate use of walkie talkies and effective management of frequency resources.
