2G Wi-Fi6 built-in antenna solution

　　The 2G Wi-Fi 6 internal antenna solution combines the second-generation mobile communication (2G) and the sixth-generation wireless LAN (Wi-Fi 6) technologies, aiming to provide a comprehensive wireless solution for specific application scenarios that can obtain Internet connection through the 2G network and provide high-performance LAN services using Wi-Fi 6. Although 2G technology is gradually being replaced by more advanced 4G and 5G worldwide, and Wi-Fi 6 itself is designed to meet higher bandwidth requirements, in some special scenarios, such as remote areas or parts of developing countries, 2G is still one of the important means of communication. Therefore, in these environments, the 2G Wi-Fi 6 internal antenna solution may have certain application value.

　　Technical Features

　　Wi-Fi 6 Feature Support

　　MU-MIMO (Multi-User Multiple Input Multiple Output): Allows routers or access points to send data streams to multiple clients at the same time, improving spectrum efficiency. For example, the XAP-6210-E wireless access point from Sundray Technologies supports 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): Reduces RF operating time, optimizes network resources, and helps reduce power consumption of terminal devices. This is especially important for IoT devices that rely on battery power.

　　Higher modulation: From 256-QAM in Wi-Fi 5 to 1024-QAM, each symbol can carry more bits of information, significantly improving throughput.

　　Dual-band support: 2G Wi-Fi 6 built-in antennas typically 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 6E14

　　Integrated 2G module

　　Integrated 2G 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 2G module that 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 infrastructure. It is worth noting that with the gradual shutdown of 2G networks around the world, the application scenarios of this combination will be limited, but it does not mean that there is no market at all. In some areas where the 2G network has not yet been decommissioned, or in extremely cost-sensitive application scenarios, there is still a certain market demand for 2G Wi-Fi 6 internal antenna solutions.

　　Application scenarios

　　Consumer electronics

　　For home users, routers that support 2G Wi-Fi 6 can provide high-speed and stable Internet services without fixed broadband access. For example, some portable 2G Wi-Fi 6 routers not only provide strong Wi-Fi performance, but also integrate 2G modules, allowing users to enjoy high-speed network connections anywhere. 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, 2G may be the only available mobile communication technology. At this time, the 2G Wi-Fi 6 internal antenna solution can play an important role. It can not only obtain Internet connection through the 2G 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 areas.

　　Internet of Things (IoT) Devices

　　With the development of the Internet of Things, more and more smart devices need to be continuously online. The 2G Wi-Fi 6 internal antenna can use 2G as a backup link while ensuring local high-speed network, ensuring that there is no interruption of service even when the network is 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 systems. However, considering the trend of 2G networks being gradually eliminated, for newly deployed IoT projects, the long-term feasibility of the 2G Wi-Fi 6 internal antenna solution should be carefully evaluated when selecting it.

　　Design considerations

　　When designing 2G Wi-Fi 6 internal antennas, manufacturers need to consider the following key factors:

　　Compactness and integration: Given the increasing space utilization requirements of 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 adhesive, which is very suitable for embedding in compact devices.

　　Material selection: The right housing material is crucial to protect the antenna from the external environment. Especially for devices working in harsh environments, such as CPE used outdoors, their antennas 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 field power supply conditions.

　　Optimize signal reception: Use advanced beamforming technology and smart antenna arrays to enhance signal reception quality, maintaining good communication performance even in the presence of weak signals or interference. For example, Huawei's AirEngine Wi-Fi 6 series products incorporate smart antenna technology derived from 5G, with 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.

　　Actual case analysis

　　Considering that 2G technology is gradually withdrawing from the mainstream market, Wi-Fi 6 built-in antenna solutions specifically for 2G may be rare in the actual market. However, this does not mean that they do not exist at all, especially under certain specific market needs, it is still possible to find relevant products or customized solutions. For example, RG-MTFi-M520 is a vehicle-mounted mobile Wi-Fi coverage device launched by Ruijie Networks. Although it mainly adopts 3G/4G terminal access solutions, its design concept and technical implementation can be a 2G Wi-Fi 6 built-in antenna solution. The device adopts a 2x2 MIMO Wi-Fi design that can support up to 802.11ac protocol, has the ability to build 2.4/5G WLAN networks, and is suitable for the development of 2G Wi-Fi 6 devices with similar needs.

　　Market Status and Challenges

　　As 2G networks are gradually shut down worldwide, new Wi-Fi 6 devices tend to support 4G or even 5G, so the actual market for Wi-Fi 6 internal antenna solutions specifically for 2G may be very limited. When considering such solutions, manufacturers should fully evaluate the support of 2G networks and the long-term development trend of the target market. Nevertheless, there may be certain needs in certain specific markets or applications, such as cost-sensitive areas or areas where existing 2G infrastructure is still in use. For example, some low-cost IoT devices may still rely on 2G networks for data transmission, because 2G modules have lower costs and lower power consumption, which is suitable for application scenarios with low bandwidth requirements.

　　Conclusion

　　In summary, although 2G technology is gradually being phased out worldwide, 2G Wi-Fi 6 internal antenna solutions still play an irreplaceable role in specific application scenarios. 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 the internal antenna will directly affect the quality of the end-user experience. If you have more specific questions or need further information, please feel free to ask questions. When designing and promoting 2G Wi-Fi 6 internal antenna solutions, manufacturers should pay close attention to the withdrawal of 2G networks and adjust product strategies based on actual conditions to ensure the market competitiveness and technological advancement of their products.
