2GWi-Fi6 built-in antenna solutions

　　The 2G Wi-Fi 6 internal antenna solution combines the second-generation mobile communication (2G) technology with the sixth-generation wireless LAN (Wi-Fi 6), 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, 2G is still one of the important means of communication in some special scenarios, such as remote areas or parts of developing countries. 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 a router or access point to send data streams to multiple clients at the same time, improving spectrum efficiency. For example, the XAP-6210-E wireless access point of Sundray Technology supports 2x2 MU-MIMO.

　　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: 2G 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 2G module

　　The integrated 2G module provides additional wide area network 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, 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 infrastructure. It is worth noting that with the gradual closure 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 retired, or in application scenarios that are extremely cost-sensitive, there is still a certain market demand for the 2G Wi-Fi 6 internal antenna solution.

　　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 powerful 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 online continuously. 2G Wi-Fi 6 internal antennas 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 switches. 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 phased out, for newly deployed IoT projects, the long-term feasibility of choosing 2G Wi-Fi 6 internal antenna solutions should be carefully evaluated.

　　Design Considerations

　　When designing 2G 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.

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

　　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 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.

　　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 supports 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.

　　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.

　　It should be noted that 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. However, in some specific markets or applications, such as cost-sensitive areas or areas where existing 2G infrastructure is still in use, there may be certain needs. When considering such solutions, manufacturers should fully evaluate the support of 2G networks and the long-term development trends of the target market.
