What is the resort intercom distance related to?

1. The call distance of the handset in a flat, open and barrier-free environment can reach 6 kilometers, but the transmission of radio waves will be affected by obstacles (such as buildings and trees); Similarly, some external factors often weaken the signal of the call, and the range of the call also changes. When there is network support, the talking distance of the walkie-talkie can reach tens of kilometers.

Second, the factors that affect the distance and effect of walkie-talkie calls are as follows:

1. System parameters:

1) The stronger the output power of the transmitter, the greater the coverage of the transmitted signal, 2) The higher the receiving sensitivity of the transmitter, the farther the communication distance.

3) The gain of the antenna, when the antenna is matched with the machine, as is usually the case, the antenna height increases, and the receiving or transmitting capability is enhanced. The antenna used in handheld walkie-talkies is generally a spiral antenna, which has a smaller bandwidth and gain than other types of antennas, and is more susceptible to human influences.

2. Environmental factors:

Environmental factors include paths, density of trees, electromagnetic interference in the environment, buildings, weather conditions, and terrain differences. These and several other parameters directly affect the field strength and coverage of the signal.

3. Other influencing factors:

1) The battery is low, when the battery is low, the call quality will deteriorate. In severe cases, there will be noise, which will affect the normal call.

2) Antenna matching.

Third, the sound quality of the walkie-talkie.

The quality of the sound mainly depends on the pre-emphasis and de-emphasis circuits, and there are currently more advanced voice processing circuits"Application of voice compaction circuits and low-level expansion circuits", which works well for fidelity voice.

The factors that affect the distance and effect of walkie-talkie calls are also related to the season, and summer is better than winter.

The first is the power of the walkie-talkie itself, followed by the surrounding environment, weather factors, battery power, etc.

Summary. The distance of the walkie-talkie is generally 2-3 kilometers.

The distance of the walkie-talkie is generally 2-3 kilometers.

5 watts 4 watts transmitting power: urban Nianfeng 1-3 doll chain, 3-5 kilometers in the open area; 3 watts 2 watts transmitting power: 500 m-2 km in urban areas, 1-3 km in open areas; 1 watt transmit power:

200 meters to 800 meters in the urban area, 500 kilometers in the open area.

The call distance of the conventional intercom stove is generally about 3 kilometers, but in the case of tall buildings or high mountains, the distance between the Tong lead call bureau will be relatively short. When there is network support, the talk range of the walkie-talkie can reach tens of kilometers.

The main purposes of the training on the use of hotel walkie-talkies are as follows:

1.Improve work efficiency: For hotel staff, walkie-talkie is a very commonly used tool that allows employees to communicate more quickly and accurately, coordinate their work, and improve work efficiency.

2.Management and supervision: Through the standardized training of walkie-talkie use, the management and supervision of hotel staff can be strengthened to avoid problems such as private calls and improper channel settings.

3.Realize safety management: The safety management of the hotel is very important, and the walkie-talkie makes the safety management more convenient, such as timely alerting other departments in case of emergency, and coordinating to respond to the incident of the Turk Tomb.

4.Improve service quality: The hotel is a service industry, and the correct use of walkie-talkies can enable hotel staff to better serve guests, respond to guest needs and complaints in a timely manner, and improve hotel service quality.

5.Reduce costs: Walkie-talkie use training is to enable employees to use the equipment correctly, reducing the failure rate and maintenance costs.

In short, the purpose of hotel walkie-talkie training is to improve work efficiency, management and supervision, achieve safety management, improve service quality, reduce costs, etc.

Mainly to facilitate communication. The use of walkie-talkie is not limited by the network, even in the place where the network is not covered, the intercom leak only can be easily communicated, what is the purpose of using the walkie-talkie training of the Kai Nai hotel: it is more convenient.

Secondly, the walkie-talkie can be one-to-one communication, or one-to-many call, so that the communication is more efficient, and the operation is simpler than returning to grandchildren, which can save a lot of time in case of emergency.

Thirdly, the use of walkie-talkie communication can greatly reduce hotel costs.

1. The distance between conventional walkie-talkies and loud spaces can reach up to 8-10 kilometers in open areas, and 3-5 kilometers in general urban areas, with tall buildings.

or in the case of high mountains, the call distance will be relatively shorter. When there is network support, the talking distance of the walkie-talkie can reach tens of kilometers.

2. The effective distance of the walkie-talkie.

In the wireless communication major, the concept of "distance" is generally not said, because ultra-short-wave communication is line-of-sight propagation, and the signal is blocked and interfered by buildings, hills, woods, electromagnetic fields, etc., which affects the actual call distance and quality, so the quality of ultra-short-wave calls is considered.

In an ideal state (without any obstruction and interference) the call distance of the professional walkie-talkie will be very long, and the actual call distance can only be between 0 10 kilometers, and in the case of tall buildings or high mountains, the call distance will be relatively short. When there is a system base station (relay) support, the talking distance of the walkie-talkie can reach more than ten kilometers or even dozens of kilometers.

The 4W 5W walkie-talkie sold on the market, the manufacturer's nominal walkie-talkie maximum call distance is 10 kilometers, in fact, this maximum call distance is only a theoretical calculation data, that is, the maximum call distance of the walkie-talkie without any obstacles and any electromagnetic interference. In actual use, due to the different environments in which the user is located, the background noise is large and small, the electromagnetic interference is strong and weak, and the actual walkie-talkie call distance is generally between 0 10 kilometers range, because it is impossible for any manufacturer to predict the user's use environment, and of course, it is impossible to give the actual call distance of the walkie-talkie.

There are many factors in how far the walkie-talkie can reach, and the use environment, walkie-talkie power, interference degree and so on are the three main factors.

If the use environment is in an open area (such as grassland, sea level), the walkie-talkie can reach a long distance. Of course, if it is a relatively closed environment, such as a city with many high-rise buildings, the walkie-talkie signal will be hindered and weakened, making the distance closer.

The power of walkie-talkie is not more than 5W transmission power in the country, and many businesses boast of 8W and 10W power. 1. It does not comply with national regulations. Second, it will have a great impact on the machine itself and reduce the service life. Third, it will also have an impact on the human body.

The degree of interference, as we all know, is the largest in the city, and all kinds of radio interference and mobile phone signal interference will have an impact on the distance.

In short, if the use environment is in an open area, it is not impossible to reach 10 kilometers.

The actual distance that can be reached in the city should be around 3 km.

There is also the walkie-talkie is divided into U-segment and V-segment, this is actually when you buy a walkie-talkie, the merchant will tell you according to your place of use, U-segment is used in the city, V-segment is used in mountainous areas, and this is the case in layman's terms.

1. Handheld walkie-talkie:

5 watts 4 watts transmitting power: 1-3 km in urban areas, 3-5 km in open areas;

3 watts 2 watts transmitting power: 500 m-2 km in urban areas, 1-3 km in open areas;

1 watt transmitting power: 200 meters to 800 meters in urban areas and 500 kilometers in open areas.

The state stipulates that the maximum power of the hand table is 5W, and there are many machines with false standards of 6W and 7W on the market, which are false parameters and are not credible).

2. Car walkie-talkie:

50 watts 40 watts transmitting power: 5-15 km in urban areas, 10-25 km in open areas;

25 watts 20 watts transmit power: 3-10 km in urban areas, 5-15 km in open areas;

10 watts 5 watts transmitting power: 1-5 km in urban areas, 3-8 km in open areas;

3. Short-wave walkie-talkie: the distance is very far, and the external environmental factors support it, it can communicate across provinces or even across borders, but shortwave walkie-talkies need an amateur radio operation certificate of level 3 or above, otherwise it will be regarded as an illegal operation.

Handheld walkie-talkie: 5 watt professional machine: 2000-5000 meters; 2 tile hand: 1000-3000 meters; Civil aircraft: 200-1500 meters.

Car walkie-talkie (usually around 25 watts): 5-15 km.

Usually used in cities, obstacles are the factor that has the greatest impact on the distance a signal travels. The actual talking distance of a professional walkie-talkie with a power of up to 5 watts in the city is generally only within the range of 2 5 km. In high ground, more buildings, or more sealed rooms, the call distance will be shorter.

However, when there is a system base station support, the call range of the walkie-talkie can reach more than ten kilometers or even tens of kilometers, (if both walkie-talkies are at a high place, it can also reach more than ten kilometers).

The walkie-talkie is not limited by the network, and in places not covered by the network, the walkie-talkie allows users to communicate easily.

The walkie-talkie provides one-to-one, one-to-many calls, one press to speak, easy to operate, and more free communication, especially in the case of emergency dispatch and collective collaborative work, these characteristics are very important.

Low call cost and increased efficiency.

Facilitate collaboration between individuals and departments.
