What is a digital intercom?

Digital walkie-talkies are portable wireless communication devices that use digital signals for communication. Compared with traditional analog walkie-talkies, digital walkie-talkies have clearer voice quality, stronger anti-interference ability, larger coverage, and more functional features.

The working principle of digital walkie-talkie is to convert voice signals into digital signals, and transmit and receive them in the form of digital signals. This digital method can provide higher communication quality and more stable connection, making communication more reliable in complex environments.

Digital walkie-talkies generally have the following features and advantages:

1. Clearer Voice Quality: Digital walkie-talkies can provide clearer and more natural voice quality, reducing the noise and interference found in traditional analog walkie-talkies.

2. Wider coverage: Digital walkie-talkies can achieve a wider coverage at the same frequency and have stronger signal penetration capabilities.

3. More functional features: Digital walkie-talkies usually have more functional features, such as SMS transmission, GPS positioning, call priority setting, etc., which make them have more application scenarios in commercial and professional fields.

4. Higher security: Digital walkie-talkies can use encryption technology to ensure the security of communications and prevent information from being illegally eavesdropped and tampered with.

In general, digital walkie-talkies have obvious advantages in voice quality, coverage, functional features and security, so they are widely used in commercial, professional and personal fields.
