The price of Huadu walkie-talkie is generally around 300 yuan, and the price will not be too high.
About the purchase of Huadu walkie-talkie;
one
Communication distance
Generally, the communication distance within 2-3 kilometers can be regarded as short-distance communication. For individual users, you can buy civil walkie-talkies. For company users, you can choose low-power walkie-talkies through application. If you want to ensure the communication effect, you can choose professional conventional walkie-talkies. Need to communicate in the city, the communication distance is within 3-10 kilometers, you can consider buying a professional walkie-talkie. If it&;s farther away, it&;s better to use the base station to communicate with the handheld walkie-talkie, or the vehicle-mounted platform to communicate with the vehicle-mounted platform. We can use the vehicle-mounted walkie-talkie with higher output power as the base station. If users need a longer distance or better communication quality, they can consider using trunked walkie-talkies without networking. Because the trunking walkie-talkie is supported by radio network, the communication distance is relatively long, and the effective distance reaches 15-30 km. Because this kind of walkie-talkie needs network support, once it is off-line, just like mobile off-line, even if the two parties are face to face, it can&;t be called.

Transmission power
For radio equipment, the size of transmission power is very important. For the same wireless equipment, the price difference between products with high transmission power and products with low transmission power is not small. Moreover, the difference of transmission power directly affects the stability of data transmission in wireless networks. Therefore, paying attention to the transmission power of the selected device is also an important link in the process of selecting wireless devices. At present, the transmission power of wireless network equipment is marked directly in the equipment specification, and some are expressed by the distance of transmission. Under normal circumstances, the transmission power of wireless devices should be between 25mW and 50mW, or the transmission distance should be between 50m and 200m. If you can&;t find the transmission power value in the equipment nameplate or manual, don&;t buy it at will-

Professional walkie-talkie
Professional walkie-talkie refers to the walkie-talkie with the transmission power of 4-5W and the frequency range of 136-174MHz or 400-480MHz. The communication distance of this kind of walkie-talkie is generally between 3 and 8 kilometers (depending on the specific environment). It is relatively simple to operate, because most professional walkie-talkies have no numeric keyboard, only two knobs to control the number of channels, power supply and volume switch. The shortcoming of professional walkie-talkie is that it is relatively large and heavy, but it is more prominent in preventing water, vibration, falling and aging, and the performance of walkie-talkie is much more stable. Professional walkie-talkies are expensive (500-2500 yuan) and are generally used in construction engineering, property management and factory workshops.
