3GWi-Fi6 built-in antenna solutions

　　The 3G Wi-Fi 6 internal antenna solution combines the third generation of mobile communications (3G) with the sixth generation of wireless LAN (Wi-Fi 6) technology, aiming to provide users with a comprehensive wireless solution that combines wide area network connectivity and high-performance LAN services. Although 3G technology is gradually being replaced by 4G and 5G, 3G is still one of the important means of communication in certain scenarios, such as remote areas or parts of developing countries. Therefore, the 3G Wi-Fi 6 internal antenna solution still has certain application value in these environments.

　　Technical Features

　　Wi-Fi 6 Feature Support

　　MU-MIMO (Multi-User Multiple Input Multiple Output): Allows a router or access point to send data streams to multiple clients at the same time, improving spectrum efficiency. For example, Wi-Fi 6 devices such as the XAP-6210-E wireless access point from Sundray Technology support 2x2 MU-MIMO7

　　.

　　OFDMA (Orthogonal Frequency Division Multiple Access): Allows multiple users to share different parts of the same channel, reducing waiting time and improving efficiency. This feature is particularly prominent in the Wi-Fi 6 standard, allowing the network to better serve a large number of concurrent users.

　　TWT (Target Wake Time): Reducing the RF working time optimizes network resources and helps reduce the power consumption of terminal devices. This is especially important for IoT devices that rely on battery power.

　　Higher modulation method: From 256-QAM in Wi-Fi 5 to 1024-QAM, this means that each symbol can carry more bits of information, which significantly improves throughput.

　　Dual-band support: 3G Wi-Fi 6 built-in antennas usually support both 2.4GHz and 5GHz bands to ensure better coverage and higher data transmission rates. Some products may also support the 6GHz band, which is part of Wi-Fi 6E.

　　Integrated 3G module

　　The integrated 3G module provides additional WAN connection options, which is particularly important for places where stable 4G or fiber broadband connections are not available. For example, some portable routers not only support the Wi-Fi 6 standard, but are also equipped with a 3G module, which can provide Internet access services by inserting a SIM card. Such devices are ideal for travelers, outdoor workers, or users in areas with weak fixed broadband infrastructure10

　　.

　　Application scenarios

　　Consumer electronics

　　For home users, routers that support 3G Wi-Fi 6 can provide high-speed and stable Internet services without fixed broadband access. For example, some portable 3G Wi-Fi 6 routers not only provide strong Wi-Fi performance, but also integrate 3G modules, allowing users to enjoy high-speed network connections anywhere10

　　. In addition, these devices are usually easy to set up and suitable for ordinary consumers.

　　Applications in special environments

　　In some special environments, such as remote mountainous areas, rural areas, or parts of developing countries, 3G may be the only available mobile communication technology. At this time, the 3G Wi-Fi 6 internal antenna solution can play an important role. It can not only obtain Internet connection through the 3G network, but also use Wi-Fi 6 technology to provide high-speed wireless network services to local users. For example, in the field of education, schools can deploy such devices to ensure that teachers and students can enjoy high-quality teaching resources and services even in remote areas10

　　.

　　Internet of Things (IoT) devices

　　With the development of the Internet of Things, more and more smart devices need to be online all the time. 3G Wi-Fi 6 internal antennas can use 3G as a backup link while maintaining local high-speed networks, ensuring that services are not interrupted even when networks are switched. This is very useful for aging facilities that need to be deployed for a long time and are not easy to replace hardware, such as sensor networks in old factories or agricultural monitoring systems1

　　.

　　Design considerations

　　When designing 3G Wi-Fi 6 internal antennas, manufacturers need to consider the following key factors:

　　Compactness and integration: Given the increasing requirements for space utilization in modern devices, internal antennas must be able to provide excellent performance in a limited space. For example, the AN.5G.INT.100.IP4 antenna launched by Maxwell uses FPC material and is installed by pasting, which is very suitable for embedding in compact devices1

　　.

　　Material selection: The right shell material is crucial to protect the antenna from the external environment. Especially for devices working in harsh environments, such as CPE used outdoors, the antenna should be able to withstand factors such as temperature changes and humidity.

　　Power management: Ensure that the antenna and its related components can operate normally within the expected operating voltage range, especially for devices that rely on PoE power supply, such as NAP-5820-X, which supports both local power supply and PoE remote power supply to adapt to different on-site power supply conditions.

　　Optimize signal reception: Use advanced beamforming technology and smart antenna arrays to enhance signal reception quality, and maintain good communication performance even in the case of weak signals or interference. For example, Huawei AirEngine Wi-Fi 6 series products incorporate smart antenna technology derived from 5G, built-in dual-band 16 smart antennas and original beamforming algorithms, ensuring that the overall performance exceeds 10Gbps and the coverage radius is significantly improved by 3

　　.

　　In summary, although 3G technology is gradually withdrawing from the mainstream market, in specific application scenarios, 3G Wi-Fi 6 built-in antenna solutions still play an irreplaceable role. They not only meet the current market demand for high-performance networks, but also pave the way for future application scenarios. Whether it is industrial or consumer products, the quality and technical specifications of built-in antennas will directly affect the quality of end-user experience.
