There are significant differences between WiFi scheme and 4G scheme in terms of communication mode, coverage, data transmission 

speed and applicable scenarios.

Communication mode and coverage:

WiFi schemes mainly rely on local area networks for data transmission, which means that users need to be within a specific WiFi coverage

 area to communicate. Its coverage is usually limited to a specific place, such as a home, office or public place.4G plans, on the other hand, 

use mobile communication networks for data transmission, so that users can maintain stable communication no matter where they are, 

as long as they have 4G coverage. Therefore, the 4G scheme has a wider coverage area, which is especially suitable for users who need 

to move frequently or distribute in different regions.

Data transmission speed and stability:

The data transmission of WiFi scheme is mainly carried out in the local area network, so its stability is relatively high. At the same time, 

with the continuous upgrading of WiFi technology standards, its transmission rate and transmission capacity are also improving, which

can meet more and more application requirements.

The data transmission speed of 4G scheme is faster, especially in the application scenarios that need to transmit a large amount of data 

in real time, such as video surveillance or high-definition voice calls, 4G scheme has more advantages. However, its stability may be 

affected by various factors such as network environment and signal strength.

The scenarios for which 4G schemes are more suitable are as follows:

Mobile office and remote collaboration: For business people who often need to travel or work in different locations, 4G solutions provide 

a stable network connection, so that they can carry out data transmission, video conferencing and remote collaboration anytime and 

anywhere, so as to improve work efficiency.

Logistics transportation and travel services: In industries such as logistics, express delivery and taxi, drivers and staff need to update cargo 

information, receive orders or communicate with customers in real time. The high-speed data transmission and wide coverage capabilities 

of 4G solutions enable these tasks to be carried out smoothly and improve the quality of services.

Emergency communications and rescue operations: In emergency situations such as natural disasters and accidents, fixed networks may be 

damaged or unable to cover. At this time, the mobile communication network of 4G scheme can play an important role in providing a 

stable means of communication for rescue workers to ensure the timely transmission of information and the smooth progress of rescue

 operations.

Outdoor entertainment: For users who like to explore outdoors, travel or participate in large events, the 4G scheme can provide real-time 

navigation, weather information and emergency rescue services. At the same time, users can also use 4G network to enjoy online music, 

video and other entertainment content, enrich the experience of outdoor activities.

The WIFI scheme is more suitable for the following scenarios:

Home network: In the home environment, the WiFi scheme provides wireless access services for various terminal devices 

(such as computers, mobile phones, smart TVS, etc.) to facilitate family members to share network resources for activities such as 

network entertainment, online learning or remote work.

Office space: In offices, meeting rooms and other office Spaces, WiFi solutions can provide stable and high-speed network connections to 

support employees in file transfer, video conferencing, online collaboration and other office activities. In addition, for large conference 

room scenarios, the WiFi scheme can also meet the concurrent needs of a large number of wireless users through reasonable planning 

of the network and configuration of RF resources.

Public places: In shopping malls, hotels, restaurants, entertainment places and other public places, WiFi solutions provide wireless 

access services for merchants, convenient for customers to connect to the network and enjoy a variety of online services. At the 

same time, merchants can also use WiFi networks for marketing and promotion activities to improve customer experience and 

service quality.

Education and medical field: In schools, hospitals and other educational and medical places, WiFi solutions can support online 

education, telemedicine and other applications, and provide convenient network services. For example, teachers can conduct 

online teaching and resource sharing through WiFi networks, and doctors can conduct remote diagnosis and treatment through 

WiFi networks.

Industrial applications: In industrial production environments, WiFi solutions can provide wireless access networks for industrial 

equipment and help enterprises in their digital transformation. For example, large machines and equipment, sensors, etc. can 

realize data transmission and remote control through WiFi networks, improving production efficiency and safety.

It should be noted that although the WiFi scheme performs well in the above scenarios, its coverage is relatively limited and it 

requires a stable power supply. Therefore, when choosing to use a WiFi scheme, it is necessary to ensure that there is sufficient 

coverage and stable power supply in the premises to meet the users' network needs. At the same time, for application scenarios

that require extremely high data transmission ratesor very low latency, it may be necessary to consider the use of more advanced 

wireless communication technologies.

To sum up, WiFi scheme and 4G scheme have their own characteristics and applicable scenarios. When choosing which scheme to use, users

 need to consider comprehensively according to their actual needs and the environment they live in.
