As an important branch of mobile communication, walkie-talkie is widely used in public security, civil aviation, transportation, water conservancy, railway, manufacturing, construction, tourism and other fields due to its strong immediacy, low cost and no restriction on network space. In high-risk industries such as petroleum, chemical, natural gas, etc., because the mobile phone may generate arc or electrostatic discharge, it is easy to cause fire. The walkie-talkie is already an irreplaceable communication tool, and its characteristics of responding to the emergency or important security Other activities are more advantageous than other communications.

The digital walkie-talkie adopts high-performance speech coding technology and high-intensity data encryption technology, which first encrypts the user's initial clear voice, and then passes the secret voice to the walkie-talkie for normal processing and transmission, voice protection and channel separation. In other words: the ciphertext transmitted between the two parties is either malicious interception or intentional or unintentional "third-party co-frequency/cross-frequency", which hears the invalid "noise" after modulation. It can effectively eliminate information leakage caused by intentional eavesdropping risk or cross-frequency, and truly realize end-to-end encryption protection at the source level for users.

The digital walkie-talkie greatly saves the radio spectrum, so the digital walkie-talkie is mostly a voice channel equivalent to occupy 6.25 kHzk bandwidth, which is half the frequency of the analog analog walkie-talkie.
The digital walkie-talkie has an in-system error correction function. The digital walkie-talkie improves and improves the integration of voice and data, and changes the weakness of the control signal as the communication distance increases. The integration of voice and data services is more complete and convenient.
