Although public walkie-talkies and amateur walkie-talkies both fall under the category of radio communications equipment, they have significant differences in their design purpose, frequency usage, power settings, and regulatory requirements they comply with. Public walkie-talkies mainly provide simple and easy-to-use operation interface and basic communication functions for daily communication needs. In contrast, amateur walkie-talkies are aimed at radio enthusiasts and not only offer a wider selection of frequencies, but also allow the use of higher power to support more complex communication experiments and technical training. The following content is a comparative analysis of the two.
Frequency allocation comparison Public walkie-talkie: A public walkie-talkie is a specific type of civilian radio communication equipment designed for non-professional daily communication. In China, this type of equipment usually works in the 409-410MHz frequency band and provides 20 preset channels for users to choose from. Its transmit power is limited to less than 0.5 watts, eliminating the need to apply for a radio operating license and reducing interference to other radio services.
Amateur walkie-talkies: As a popular radio communication tool, amateur walkie-talkies provide radio amateurs with a wide range of frequency selections and relatively high power usage, allowing them to conduct more diverse and long-distance communications. According to the "Radio Frequency Allocation Regulations of the People's Republic of China", amateur radio stations are allocated multiple frequency bands, including VHF (very high frequency) and UHF (ultra high frequency) bands, as well as wider frequency ranges.
For example, amateur radio stations have specific frequency allocations within 144-148MHz of the VHF band and 430-440MHz of the UHF band. These frequency bands are widely used by the global amateur radio community for local communications, long-range communications and even satellite communications. In addition, the maximum radiated power of amateur radio stations within specific frequency bands is often limited to avoid interference with other radio services.
Power limit comparisonPublic walkie-talkies: The power limit is lower, usually no more than 0.5W. This is to ensure that public walkie-talkies do not cause interference to professional radio communications.
Amateur walkie-talkies: The power limit is relatively high and can reach more than 5 watts, but it is still limited by specific frequency bands and usage conditions. Amateur walkie-talkie users need to abide by radio management regulations and must not cause harmful interference to other radio services.
Comparison of regulatory requirementsPublic walkie-talkie: easy to use, no radio operating license required. There are no radio frequency occupancy fees to pay.
Amateur walkie-talkies: Users need to be familiar with radio management regulations and pass verification of operational technical capabilities. Amateur radio stations may only be used for mutual communication, technical research and self-training, and may not be used for commercial gain.
Comparison of usage scenariosPublic intercom: suitable for short-distance communication in daily life, such as family, small activities, etc.
Amateur walkie-talkies: suitable for radio enthusiasts to conduct technical exchanges, participate in amateur radio competitions and experiments, etc.
Comparison with or without license
Public walkie-talkies: Suitable for ordinary users who do not need professional radio knowledge and can be used without a license.
Amateur walkie-talkies: Suitable for amateurs with certain radio knowledge and skills. They need to pass an assessment to obtain an operation certificate, and apply for station registration and call sign in accordance with the regulations of the national radio management agency. Only after obtaining a license can it be used legally.
in conclusion
The use of amateur walkie-talkies and public walkie-talkies is subject to specific legal restrictions. These restrictions involve frequency range and transmit power. The purpose is to reasonably allocate radio spectrum resources and ensure the coordination and coexistence between various radio services. Public walkie-talkies are designed to be user-friendly and easy to operate, while amateur walkie-talkies are aimed at radio enthusiasts, providing wider frequency options and higher power settings to adapt to more advanced communication tasks and technological innovations. When using these devices, users should strictly abide by the corresponding laws and regulations to ensure the legality and efficiency of communication.https://yategood.com/
