In terms of design technology, wireless walkie talkies can be divided into analog walkie talkies (commonly known as traditional walkie talkies) using analog communication technology and digital walkie talkies designed using digital technology. Analog walkie talkies modulate stored signals onto the transmission frequency of walkie talkies, while digital walkie talkies digitize speech information and propagate it in digital coding form, that is, all modulation on the transmission frequency of walkie talkies is digital. Digital walkie talkies have significant advantages such as strong speech anti-interference ability, clear speech, high confidentiality, narrower channel bandwidth, and stronger data transmission ability.

1、 The traditional analog walkie talkie is a communication mode that modulates speech, signaling, and signals in a continuous wave manner onto the carrier frequency of the walkie talkie and undergoes optimization processing such as amplification. It has the advantages of mature technology, complete system, and relatively low cost.

2、 Digital walkie talkies are data-driven communication modes that digitize speech signals using specific digital encoding methods and baseband modulation forms, and optimize them using digital signal processors. Firstly, spectrum resources can be better utilized. Similar to cellular digital technology, digital walkie talkies can load more users on a designated channel, improving spectrum utilization, which is a solution to frequency congestion. Secondly, improve the quality of calls. Due to the built-in error correction function of digital communication technology, compared to analog walkie talkies, it can achieve better speech and audio quality in a wider range of signal environments, resulting in less received audio noise and clearer sound.

Thirdly, improve and enhance the integration of voice and data, and address the weakness of control signals decreasing with increasing communication distance. Compared with similar integrated analog voice and data systems, digital walkie talkies can provide better data processing and interface functions, allowing more data applications to be integrated into a bidirectional wireless communication base station structure, making the integration of voice and data services more comprehensive and convenient. With the development of wireless communication technology, the increasing demand for wireless communication quality and the increasing scarcity of spectrum resources, digital walkie talkies will inevitably have a huge market demand. At present, the demand for digital walkie talkies in China is also constantly increasing.
