1、 The traditional imitation of walkie talkies is a communication method that modulates voice, signaling, and signals onto the walkie talkie carrier frequency using continuous wave modulation, and optimizes them through amplification and other processing techniques. Has the advantages of skilled experience, complete system, and relatively low cost.

2、 Digital walkie talkie is a data-driven communication method that digitizes voice signals using specific digital encoding methods and baseband modulation techniques, and optimizes them using digital signal processors.

Firstly, it enables better utilization of spectrum resources. Similar to cellular digital technology, digital walkie talkies can load more users on a designated channel, improving spectrum utilization, which is a solution for dealing with frequency congestion.

Secondly, improving the quality of calls. Due to the inherent fault correction function of digital communication skills, compared to imitating walkie talkies, it can achieve better voice and audio quality in a wider range of signal environments, with less audio noise received and clearer sound.

3. The last point is to improve and enhance the integration of voice and data, and to address the drawback of control signals decreasing with increasing communication distance. Compared with similar integrated imitation voice and data systems, digital walkie talkies can provide better data processing and interface functions, enabling more data applications to be integrated into the same bidirectional wireless communication base station structure, making the integration of voice and data services more complete and convenient.

Compared to traditional imitation walkie talkies

Strong anti-interference ability for speech

High confidentiality

The channel occupies a narrower bandwidth

Significant advantages such as stronger data transmission capability

Digital walkie talkies are mainly suitable for the following groups:

1. Require clear voice quality and better confidentiality.

Not only does it require complete scheduling functions, but it also requires complete data transmission functions.

3. Have long-term planning and sufficient budget funds# Page Title # e#

Additionally, the following information industry can be used as a reference

1、 Comparison between digital cluster walkie talkies and imitation conventional walkie talkies

Digital cluster walkie talkie has clear voice and stable reception of call signals;

Digital cluster walkie talkies can not only simulate the fundamental tasks of walkie talkies, such as single call and group call functions, but also have compensatory tasks such as call verification, area selection, access priority, priority call, late entry, pre occupancy priority call, listening, dynamic reorganization, and monitoring by the dispatch console. That is to say, digital cluster walkie talkies can provide a wider range of transaction types, better transaction quality, better confidentiality features, better connectivity, and higher spectrum power.

2、 Comparison between digital cluster walkie talkies and civilian mobile phones

Although the fundamental and remedial aspects of civilian walkie talkies in the world are now diversified, with transmission rates reaching up to 9.6kbit/s to 2Mbit/s at the fastest; But its users are only for general mobile communication transactions, and due to market sales and manufacturing costs, it cannot meet the requirements of another special group of users for mobile terminal professionalism, high privacy, and unified scheduling capabilities.
