When choosing a walkie talkie, its waterproof, durable, and low-temperature performance should be considered.
However, with the development of technology, modern walkie talkies have shed their bulky and outdated image and become more lightweight, fashionable, and powerful. Modern walkie talkies not only have a compact appearance and exquisite design, but also have waterproof, dustproof, and impact resistant characteristics, making them very suitable for outdoor activities and extreme sports. They are also equipped with high-definition voice, long endurance, and wide signal coverage, allowing skiers to maintain smooth communication even in harsh weather and complex terrain. In addition, some high-end walkie talkies also support intelligent functions such as Bluetooth connection and GPS positioning, further enhancing the skiing experience and safety. Therefore, modern walkie talkies have become one of the indispensable equipment for skiing enthusiasts.
In addition to traditional wireless walkie talkies, public network walkie talkies, as a new type of communication tool, achieve long-distance communication through mobile networks, with simple operation and diverse functions, making them very suitable for outdoor activities and team collaboration.
The Cost of Use
The usage costs of public network walkie talkies and wireless walkie talkies each have their own characteristics. The cost of public network walkie talkies mainly includes equipment purchase costs and subsequent traffic usage fees. For example, the price of sport walkie talkie ski version is approximately USD$88, and the annual fee for the IoT card varies depending on the service provided, ranging from USD$ 8 to 30 . The advantage of this type of walkie talkie is that it can achieve a wide coverage range and can be used almost anywhere with network signals. The price range of wireless walkie talkies is wide, ranging from few dollars to thousand dollars, depending on performance and functionality. Although the radio does not need to pay for Internet traffic, users need to pay a certain frequency occupancy fee, which is usually about USD$ 16 per year. In addition, some helmets and snow goggles designed specifically for skiing now integrate intercom functions. These devices usually support two communication methods: 4G and radio frequency, combining the advantages of public and radio intercoms, providing users with more convenience and choices.
Traditional wireless walkie talkies have relatively low communication latency in environments without obstacles and minimal interference, and are often used in emergency communication, public safety, and other scenarios that require quick response.
Waterproof and durable
Waterproof durability is one of the considerations for skiers when choosing walkie talkies. For example, some wireless walkie talkies are labeled with an protection level of IP54, while the popular 318 walkie talkies are labeled as IPX6. What do IP54 and IPX6 mean?
IP54 refers to the dust and water resistance of electronic product casings. Among them, the number “5” represents a dust level of 5, which means that the product casing cannot completely prevent dust intrusion, but the amount of dust intrusion will not affect the normal operation of the product. The number “4” represents a waterproof level of 4, indicating that the product casing can prevent water splashing from all directions from entering, but cannot prevent strong water flow or spraying.
Let’s talk about IPX6 again, where the letter X represents not having undergone dust prevention testing; The number 6 indicates that the waterproof level is level 6, and the product is required to successfully defend against water spray with a water flow rate of 100 L/min for 3 minutes and still be able to operate normally.
The walkie talkies labeled with IP54 and IPX6 indicate that they have good waterproof properties, and snow enthusiasts can use them with confidence in rainy or snowy environments.
The correct use of walkie talkies is crucial!
Radio walkie talkies and public network walkie talkies each have their own advantages, disadvantages, and applicability, and can be selected based on skiing areas, network coverage, and other factors. Of course, the correct use of walkie talkies is also crucial~
1. After debugging, go to Skiing
It is very important to ensure that the walkie talkie is working properly before skiing. Different types of walkie talkies require different checks and preparations.
**Public intercom * *:
-Check the battery level to ensure it is sufficient.
-Use the corresponding application for device pairing.
-Simplify the process of creating or joining groups by utilizing the one click quick team building feature.
**Radio intercom * *:
-Also check the battery level to ensure there is enough power to support full day use.
-Confirm the frequency of use and backup frequency for use when the main frequency is blocked.
-Adjust the walkie talkie to the correct frequency and conduct a test call to ensure smooth communication.
Through these preparations, communication issues that may arise during skiing can be minimized to the greatest extent possible, ensuring that snow enthusiasts can safely and smoothly enjoy the fun of skiing.
2 .Don’t talk nonsense or tell jokes
As a communication tool, walkie talkies can indeed play a crucial role in emergency situations and even become life-saving tools. In outdoor activities such as skiing, the use of walkie talkies should follow certain principles and etiquette to ensure effective communication and avoid unnecessary interference.
When using walkie talkies, meaningless chatting or prolonged channel occupation should be avoided, which can ensure timely transmission of important information in emergency situations and reduce interference with other users. At the same time, reasonable use of walkie talkies can also help save battery power and extend the lifespan of the device.
In practical operation, users should first understand and comply with the rules for using walkie talkies, such as:
-When speaking, try to be concise and clear, conveying necessary information.
-Avoid frequent and ineffective calls to avoid interfering with the normal use of others.
-In non emergency situations, try to use non emergency channels or private channels for communication.
-Understand and respect local radio communication regulations and frequency usage rules.
By using walkie talkies reasonably and effectively, not only can the safety of outdoor activities be improved, but also the overall communication efficiency and experience can be enhanced.
3. Add “Over” at the end of the call
In movies and TV dramas, when using a walkie talkie for a call, the last word is often said: “Done” or “Over”, which looks like it’s a dead end. This is not a catchphrase, but rather one of the rules for using a walkie talkie, which is related to the way the walkie talkie works.
The working mode of walkie talkies is half duplex, which means that at the same time, voice can only be transmitted unidirectionally from one party to the other, either you say I listen, or I say you listen. If both parties speak at the same time, no one can hear what the other person is saying, and there is no way to know if the other person has heard.
The walkie talkie has formed a usage rule: one party adds “Done” or “Over” at the end of the call to indicate that the conversation has been completed, and the other party can only speak after hearing “Done” or “Over”.
This is the truth and usage rules of the “really fragrant” walkie talkie!

How to improve the communication distance of walkie talkies? The following suggestions are arranged based on convenience and cost of use
Increase launch altitude:
There is a saying circulating in the circle of amateur radio enthusiasts: “Height determines everything!” Practice has proven this to be a truth. The principle is very complex, and we will not elaborate on it here. When buying handheld walkie talkie , everyone sees this indicator: communication distance of 3-xx kilometers, which refers to the communication distance in open ground areas. And what would happen if you stood on the mountaintop with a handheld platform? The fact is that you can still connect with friends from another high-rise building!
Choose communication environment and direction:
Choosing the communication environment and direction is important, as it can sometimes lead to significant differences in connectivity quality. Generally, we should follow the following principles:
A. Try to choose a higher terrain for connectivity, such as if you can connect on the second floor, not on the first floor.
B. Try to choose outdoor communication as the building walls have strong reflection and attenuation of 70 centimeter waves.
C. Try to avoid residential areas surrounded by buildings, densely packed buildings in the old city area, areas with dense trees, under high-rise buildings, road sections surrounded by large cars, tunnels and bridges, and large metal billboards in front of you.
D. Utilizing urban canyons: This is very important. In our big cities, there are numerous tall buildings and dense buildings, making it difficult to find real opportunities for line of sight transmission. Therefore, we need to make good use of the existing environment. The so-called urban canyon refers to the dense and tall buildings on both sides, as well as the wide and winding main roads. Even if connected on the same route as its intersection (such as vertical or diagonal sections), the connectivity effect is generally good. On the contrary, if both parties are in a complex path or building complex, the connectivity effect will be very poor. Therefore, we propose that if you are planning to connect while driving, please start after entering the wide road.
E. Choose the correct direction and avoid the obstruction of tall buildings and metal structures as much as possible between the points connected to you. If you place it behind your connecting direction, it can also serve as a signal reflector.
F. Nighttime connectivity is more effective than daytime connectivity.
G. Fixed point connectivity is more effective than mobile connectivity.
Improve receiving sensitivity:
I don’t think I need to explain this further. If both parties increase the receiving sensitivity, it is equivalent to increasing the transmission power for the other party. Please don’t tell me that you don’t know how to adjust the receiver sensitivity of the radio station, as this is included in the manual.
Using high gain transmitting antennas:
The efficiency of antennas is represented by gain, and different types of antennas have different gains. Generally speaking, specialized extended handheld antennas (commonly known as small whip antennas) are better than the original handheld antenna (gain of approximately 2.15DBi), car mounted antennas are better than small whip antennas (gain of 5.5-6.5DBi), pole mounted antennas are better than car mounted antennas (gain of 6.5-12DBi), and multi unit unidirectional antennas (such as Yagi antennas, logarithmic periodic antennas, circular antennas, etc.) are better than pole mounted antennas (gain of 9-24DBi).
It is strongly recommended that friends who are connected in the car use a car antenna. Keep in mind that every 3DBi gain is equivalent to doubling the transmission power of your radio station. At the same time, it avoids signal shielding of your handheld device inside the car and radiation to the human body inside the car.
Students who set up a station at home recommend using a rod antenna, which has high gain, high strength, and is easy to install. With the installation height on the rooftop, it is not a problem to cover the entire city, and some can be connected to other cities.
Increase transmission power
Some students can’t help but ask: When I bought my handheld walkie talkie, the power was already set. How can I increase the power? In fact, there are still ways:
A. The transmission power of handheld walkie talkies is related to the voltage and capacity of the battery. When fully charged, the transmission power is higher, and vice versa. And most of the time our handheld walkie talkies work in a low battery state, so we recommend using lithium batteries that can be charged at any time to ensure maximum transmission power.
B. Some models of handheld walkie talkies can set their own transmission power (such as the Lingtong 6288), and can set a transmission power higher than 5W.
C. Some radio stations can use external power sources (nickel hydrogen batteries) to ensure maximum transmission power of handheld walkie talkies.
If the input voltage of the external power supply is increased (higher than the nominal battery voltage but lower than 13.8 volts), it can increase the nominal transmission power of the handheld walkie talkie. For example, the Beifeng 71-B can output nearly 5W of transmission power under a voltage of 12V-13.5V. But it is recommended that students use this method with caution. If the call time is too long or there are no appropriate heat dissipation measures, it is easy to burn out the amplifier module.
Using relay stations for transfer:
The so-called relay station is a type of relay station set up at a high altitude, which uses uplink frequency to receive radio signals with varying strengths at scattered points and converts them into downlink frequency equal power transmission. It can be composed of two radio stations, one power supply, and corresponding control conversion circuits. The armed police, public security, transportation and other departments use this type of relay station to ensure that users have no blind spots and high-quality communication.
