"You get what you pay for" has become a deeply rooted way of thinking in people's minds; the better the product, the more objective the price. In fact, this is not the case. Everything has different prices according to different needs. It is fair to buy one that suits you. Many users who want to buy walkie-talkies are always hesitant when buying, not knowing what walkie-talkie they should buy? Which walkie-talkie brand is better? Is it a civilian machine? Or a professional machine? Are expensive walkie-talkies necessarily good?
Communication distance
Generally, the communication distance within 2-3 kilometers can be regarded as short-distance communication. For individual users, civilian walkie-talkies can be purchased. For corporate users, low-power walkie-talkies can be purchased by application. If you want to ensure the communication effect, you can choose professional conventional walkie-talkies. If you need to communicate within the city, the communication distance is within 3-10 kilometers, you can consider buying a professional walkie-talkie. If it is farther away, it is best to use a base station to communicate with a handheld walkie-talkie, or a car-mounted station to communicate with a car-mounted station. We can use a car-mounted walkie-talkie with a relatively large output power. If the user needs a longer distance or better communication quality, if he does not have a network, he can consider using a cluster intercom. Because the cluster intercom is supported by the radio network, the communication distance is relatively long, and the effective distance reaches 15--30KM. This kind of intercom needs network support, so once it is disconnected from the network, it is like a mobile phone disconnected from the network. Even if the two parties are face to face, they cannot call each other.
Transmitting power
For radio equipment, the size of the transmitting power is crucial. For the same wireless device, the price difference between products with high transmitting power and products with low transmitting power is not small. Not only that, the difference in transmitting power also directly affects the data transmission stability of the wireless network. Therefore, paying attention to the transmitting power of the selected device is also an important part of the selection process of wireless devices. At present, the transmitting power of wireless network equipment is either directly marked in the equipment manual, or indicated by the distance of the transmission distance. Under normal circumstances, the transmitting power of wireless equipment should be between 25mW and 50mW, or the transmission distance should be between 50 meters and 200 meters. If you cannot find the transmitting power value on the equipment nameplate or manual, do not buy it at will.
Professional walkie-talkie
Professional walkie-talkie refers to a walkie-talkie with a transmission power of 4-5W and a frequency range of 136-174MHz or 400-480MHz. The communication distance of this type 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 do not have a numeric keypad and only have two knobs to control the number of channels and the power and volume switches. The disadvantage of professional walkie-talkies is that they are large and relatively heavy, but they are more prominent in terms of water resistance, vibration resistance, drop resistance, and aging resistance, and the performance of the walkie-talkie is much more stable. The price of professional walkie-talkies is relatively high (500-2500 yuan) and they are generally used more in construction projects, property management, and factory workshops.
Commercial walkie-talkie
Commercial walkie-talkie refers to a walkie-talkie with a transmission power of 0.5-4W and a frequency range of 400-480MHz. The communication distance of this type of walkie-talkie is between 800 meters and 8 kilometers (depending on the transmission power of the walkie-talkie and the specific environment). The appearance of commercial walkie-talkie is light and beautiful. The walkie-talkie can be tied around the waist through the belt clip of the walkie-talkie. Wearing headphones can free your hands and improve work efficiency. The price of commercial walkie-talkie is relatively high, just like professional walkie-talkies. It is generally used in shopping malls, supermarkets, retail industries, factories, and manufacturing industries.
Civilian walkie-talkie
Civilian walkie-talkie refers to a walkie-talkie with a transmission power of 0.5W not more than 1W and a frequency range of 409MHz. The communication distance of civil walkie-talkie is generally short (3 kilometers in open areas). It is a wireless communication device approved by the state to be used without a license. Civilian walkie-talkies are small in size, colorful, and low in price, generally only 300-600 yuan, which is more suitable for personal business trips, tourism, and restaurant use.
Amateur walkie-talkies
Amateur walkie-talkies are radio walkie-talkies designed and produced specifically for amateur radio enthusiasts. This type of walkie-talkie can also be called a "play machine". For this kind of amateur personal radio business, various countries have opened up special frequency bands for amateur radio sports enthusiasts. The frequency bands opened up in my country are 144~146MHZ and 430~440MHZ, and countries around the world generally use this frequency band. Amateurs only need to buy the model they like and apply for a local radio network access license, and they can chat with others. Countries around the world generally use this frequency band.
Explosion-proof intercom
Among the many wireless intercom brands, there are not many brands with explosion-proof intercoms. Currently, there are only a few intercom brands on the Chinese market, including (MOTOROLA), (VertexStandard), Gangsen, (Hytera), BFDX, and JOLODA. Motorola explosion-proof intercoms have taken over the Chinese explosion-proof intercom market with their superior performance. Explosion-proof intercoms refer to intercoms that can work in flammable and explosive environments, such as: coal mines, liquefied gas filling companies, oil depots, oil fields, petroleum, gas stations, chemicals, petrochemicals, coal mines, mines, natural gas, chemical plants, flour mills, flax mills, coal mills, and firefighting.
Railway intercom
Railway intercoms are undoubtedly special intercom equipment tailored for railways and railway departments by intercom manufacturers based on the actual work needs of railways and railway departments. The transmission power is 4-5W, and the frequency range is 440--470MHz. There are generally 2-4 function buttons on the front of the housing of the railway intercom, which are used to select different communication environments such as plains and tunnels, and to switch between stations and locomotives. Due to the high noise of train running, the audio output of the intercom is very high. Intercoms use voice compression and expansion to make the call sound clearer and crisper.
Police intercom
Police intercom is a special equipment for the public security system. The frequency range of police intercom is 350-370MHz and 370-390MHz. No one may steal or misappropriate the frequency resources of the special intercom for the public security system in any way. Police intercoms have many functions, and most of them are keyboard-type. When we buy wireless intercoms, we should pay attention to the fact that the transmission frequency range of intercoms is mostly (400-420MHz, 450-470MHz) to avoid unnecessary trouble.
Car intercom
The working voltage of the car intercom is 12.5V. The current car voltage is divided into 12V and 24V. When the car intercom is to work on a car with a voltage of 24V, a transformer needs to be installed between the car and the intercom. The transmission power of the car intercom is 25-50W, which is relatively large and the signal is transmitted farther. The car intercom can only be fixed in one place, and it is not as convenient to use as a handheld intercom. Car intercoms are generally used in fleets.
Relay station base station
The specific function of the relay station and base station is to transmit the received wireless signal with greater power through internal processing, so as to achieve the extension of the wireless communication distance. To put it simply, the relay station and base station are a wireless communication signal amplifier. As your company's business develops and grows, the demand for two-way communication is also expanding. Using repeaters and base stations can enhance your communication capabilities. Our powerful dispatch stations and repeaters can facilitate the coordination of system resources and expand the communication range of your walkie-talkies.
