To choose a walkie-talkie suitable for the construction site, you need to consider multiple factors such as communication capability, usage environment, functional configuration, ease of operation and cost. The following are specific suggestions:

Communication capability

Power and distance: The construction site is large, with many buildings and obstacles. It is recommended to choose a walkie-talkie with a power of 5W or above, such as the BelFone SA800 walkie-talkie, which has a 7W high-power design and strong penetration, and can meet the long-distance communication needs between different areas of the construction site.

Frequency range: The UHF (ultra-high frequency) band walkie-talkie signal has strong penetration ability and is suitable for use in construction sites with many obstacles such as cities; if the construction site is in an open area, the VHF (very high frequency) band can be selected, which has better transmission effect in open space.

Ability to adapt to the environment

Protection level: The construction site environment is harsh, with dust, mud and water, etc., so you should choose a walkie-talkie with a protection level of at least IP54, which has good dust and splash resistance. If you often use it in the rain or humid environment, an IP67 waterproof and dustproof walkie-talkie is more suitable. For example, BP610 digital walkie-talkie has IP68 dust and water resistance. The shell is made of wear-resistant and heat-resistant PC protective material, which can remain intact in rain, soaking, dust and other environments. The screen has been reinforced with excellent impact resistance and can withstand a 1.5-meter fall at multiple angles, easily capable of various harsh working environments. .

Anti-fall performance: Construction site workers may accidentally drop the walkie-talkie during operation, so you should choose a product with a sturdy shell and good anti-fall performance. For example, the shell of BF-500 is made of PC+ABS material, which is sturdy and durable, with good anti-fall and wear resistance.

Anti-interference ability: There are many electrical equipment on the construction site, and the electromagnetic interference is serious. The walkie-talkie needs to have strong anti-interference ability. You can choose a product with a noise suppression function, which can effectively suppress noise and improve call quality.

Function configuration

Battery life: The working hours on the construction site are long, and the walkie-talkie is used frequently. You need to choose a product with large battery capacity and long battery life. For example, BF-500 is equipped with a 4000mAh large-capacity battery, which can achieve 300 hours of ultra-long standby and 29 hours of continuous talk, which can meet the high-frequency call volume requirements of the construction site for two days.

Number of channels: If there are multiple groups working on the construction site at the same time, and different groups need to communicate independently, you should choose a walkie-talkie with a large number of channels, preferably 16 channels or more, so that different groups can use different channels separately to avoid mutual interference.

Additional functions: Walkie-talkies with GPS positioning function can allow managers to grasp the location information of workers in real time, which is convenient for dispatching and management. For example, CM625S nationwide 4G public network walkie-talkie supports unlimited distance calls within 5,000 kilometers nationwide, and has GPS positioning function. It can monitor and view the dynamic information and route trajectory of each group member in real time. At the same time, combined with the 4G network, it can obtain data information more accurately, faster and more comprehensively; BelFone ProChat IoT cloud system management platform has the function of motion trajectory playback. Users can easily grasp the dynamic information of mobile vehicles/personnel, and form a visual digital cluster management and dispatching platform from top to bottum, realizing "no dead angle" tracking across the country, facilitating management and dispatching between personnel at different levels, thereby effectively improving user work efficiency.

Convenience of operation

Key design: The buttons of the walkie-talkie should be large and clear, convenient for operation with gloves, and the layout should be reasonable. Commonly used function keys such as call keys and volume adjustment keys should be easy to find and operate.

Display screen: Intercoms with display screens can more intuitively view information such as channels, power, signal strength, etc. It is best to choose products with high display brightness and good contrast, which can clearly display content even under strong light.

Frequency matching method: The one-button frequency matching function can greatly improve the setting efficiency of intercoms, especially when there are a large number of two-way radios on the construction site that need to unify the frequency, which can save time and energy. For example, the BelFone BF-316 supports one-button copying of the other  frequency point and CTCSS sre instantly read and saved with one button, making it easy to communicate with other radios in real time. Compared with traditional analog radios, there is no need to reprogram the frequency.

Sound quality: The construction site is noisy, so the sound quality of the radio is very important. You should choose products with noise reduction function and loud speaker volume. For example, the BP620 digital intercom is equipped with a high-performance speaker + AI intelligent noise reduction algorithm, which can effectively filter background noise and eliminate howling, accurately extract human voice, and ensure that the intercom sound can still be accurately captured in various noisy areas, achieving clear and loud call effects.

Brand reputation: Walkie-talkies of well-known brands are more guaranteed in terms of quality, performance and stability.

After-sales service: Good after-sales service can make users worry-free during use. Choose a brand with a complete after-sales service network and timely response, so that they can get repair and maintenance services in time when the walkie-talkie fails.
