How to Choose a Walkie-Talkie Module: Unikeyic Explains the Difference Between UHF and VHF Frequencies

Many enterprises find themselves perplexed when choosing between UHF and VHF frequency bands while placing bulk orders for walkie-talkie modules. To address this issue, it may be beneficial to consult the walkie-talkie module selection guide available on Unikeyic. The key is to select a module based on your specific usage needs. Here is an overview of how to choose the right walkie-talkie module according to different usage environments. Domestic Walkie-Talkies Predominantly Use UHF BandsSince the walkie-talkie module significantly affects the actual user experience, it’s crucial to choose based on practical requirements, starting with confirming the module's frequency band. The commonly used frequency bands for walkie-talkies are primarily UHF and VHF. The main distinction is that UHF operates in the 400-480MHz range, while VHF covers the 134-174MHz range. In China, walkie-talkies typically operate within the 400-480MHz range, making UHF the predominant choice.Frequency Band Does Not Determine Communication DistanceMany people focus on communication distance when selecting walkie-talkie modules, but it’s essential to note that operating frequency does not determine communication distance. Instead, it is necessary to choose the frequency based on the actual usage environment to maximize communication range. For instance, according to electromagnetic theory, lower frequencies mean longer wavelengths, making UHF more suitable for high-rise urban settings. Conversely, for open outdoor spaces, VHF is preferable as it can increase communication distance.Tailor Configurations to Specific NeedsThe reason why it's recommended to check out the walkie-talkie guides on unikeyic is that such industry websites often boast a rich supply of products. This allows you to select the most suitable module according to your needs. For example, if you're concerned about poor signal quality, you can add signal gain to any type of walkie-talkie, regardless of its frequency band, thereby enhancing signal strength.When procuring walkie-talkie modules, it is vital to heed the aforementioned guidance while also leveraging the resources provided by industry websites like Unikeyic. This approach enables you to reference numerous walkie-talkie module use cases, ensuring you purchase the module that best meets your specific requirements.
