In the case of outdoor hiking, cycling, and self-driving tours, you must prepare special equipment for outdoor wireless walkie-talkies in advance. This is because there is no signal coverage in many areas outside, so you must choose outdoor wireless walkie-talkies, and everyone should be skilled Master the operation method of outdoor wireless walkie-talkie.
Professional wireless walkie-talkie operation method
The characteristics of professional wireless walkie-talkies are 0.3-5W adjustable transmission power, firmness, durability, long rechargeable battery life, relatively speaking, other types of machinery and equipment are relatively large, the transceiver frequency is within the professional frequency range, and basically cannot be moved randomly. , Complete internal functions, singular external functions.
All internal functions are controlled by the wireless walkie-talkie CPU. It can realize powerful functions such as wireless networking, phone calls in working groups, data communication, ID identification, and remote killing in the air.
This is because it has complete functions, so it is especially suitable for outdoor, harsh environment (requirements for rechargeable batteries are very high), and group use. The simplification of external functions is because it is not easy to cause operating errors. Nowadays, special-purpose machines with advanced functions are considered to be attacked if the human body is tilted, or if the body falls on the ground. The distress signal draws the attention of the group as much as possible.
Operation method of civil walkie-talkie
The characteristic is that the transmit power is adjustable from 0.3 to 5W, and the basic external functions are extremely powerful. In addition to the basic functions of a professional machine, it also has a lot of additional basic functions. The most interesting thing is that it can be used as a radio to listen to when idle.
And most of these devices are dual-segment devices, which can receive and transmit at the amateur frequencies of 150MHZ and 400MHZ. According to a moderate spread spectrum scheme, they can be extended to the full range of working frequencies.
Because of its complete functions and lightweight body, it is loved by amateur radio enthusiasts all over the world. In general, it is lightweight and has the same transmit power as professional machines, so most of them have the problem of short battery life.
For outdoor use, pay special attention to bringing more than 2 sets of emergency rechargeable batteries, or bring an upgraded large-capacity lithium battery pack. Of course, the most important thing is that the price is double or more than that of professional machines. .
Free camera operation method
Because my country has strict requirements for the use of wireless communication operating frequencies, no matter whether it is a professional or civilian machine, it cannot be used freely. Special attention should be paid to this point. If the regular business working frequency is squeezed out due to illegal use of the working frequency, it will be suddenly knocked to the ground by public security personnel.
In order to connect with the world and at the same time meet the strong demand of Chinese users to open up wireless communication operating frequencies, my country’s recent
In the past few years, 20 frequency points with 409MHZ as the main operating frequency were opened to the outside world as a license-free operating frequency. Everyone does not need to apply for this operating frequency and can be used casually. There are only strict restrictions on the transmission power, and the power cannot exceed 0.5W. .
Master the communication distance of wireless walkie-talkies
Wireless walkie-talkies do not distinguish the concept of how far they can communicate. Often someone wants a 10-km wireless walkie-talkie or a 5-km wireless walkie-talkie. This kind of questioning can only cause you to be slaughtered or become discouraged in using it.
The working frequency used by wireless walkie-talkies is line-of-sight propagation, that is to say, on the earth, it can be reached where the eyes can see. In the second palace of Urumqi, you can use 5W power + outdoor antenna to directly talk to the summit of Bogda. The actual effect is better. This is a very obvious example.
In addition to using wireless walkie-talkies outdoors, we also use wireless walkie-talkies in many other places. Like the current epidemic, wireless walkie-talkies have played a vital role.
