4GWi-Fi6 built-in antenna solutions

　　The 4G Wi-Fi 6 internal antenna solution combines the technical advantages of the fourth generation of mobile communications (4G LTE) and the sixth generation of wireless LAN (Wi-Fi 6), providing efficient, stable and fast wireless connectivity for various devices. This type of solution not only supports traditional Wi-Fi applications, but also enables wider coverage and service quality assurance by integrating 4G LTE modules. The following is a detailed discussion on the 4G Wi-Fi 6 internal antenna solution.

　　Technical Features

　　Support for a variety of advanced technologies

　　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-MIMO17

　　.

　　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 users7

　　.

　　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 power8

　　.

　　Dual-band support: 4G Wi-Fi 6 built-in antennas usually support both 2.4GHz and 5GHz bands to ensure better coverage and higher data transmission rates. For example, the YEMA004AA 2-in-1 threaded IoT antenna supports 4G/LTE and Wi-Fi/BT connections for different application scenarios20

　　.

　　Efficient data transmission

　　4G Wi-Fi 6 built-in antennas are designed to maximize data throughput. The modulation method under the Wi-Fi 6 standard has been improved from 256-QAM in Wi-Fi 5 to 1024-QAM, which means that each symbol can carry more bits of information, thereby significantly improving throughput. In addition, the wide area network connectivity provided by the 4G LTE module complements the local area network advantages of Wi-Fi 6, ensuring a good Internet connection even when the Wi-Fi signal is poor9

　　.

　　Application scenarios

　　Consumer electronics

　　For home users, routers or CPE (customer premises equipment) that support 4G Wi-Fi 6 can provide high-speed and stable Internet services without fixed broadband access. For example, KuWFi 4G LTE Router provides a portable solution with built-in 4G dual antennas and supports speeds of up to 150Mbps, which is very suitable for travelers or people who need temporary high-speed Internet access21

　　.

　　Industrial and commercial environments

　　In industrial or commercial environments, 4G Wi-Fi 6 built-in antennas are more widely used. They can be used to build a reliable wireless infrastructure to support mission-critical applications such as automated production lines and remote monitoring systems. For example, some CPEs not only have built-in 2T2R WiFi antennas to support up to 160MHz bandwidth and AX3000-level wireless specifications, but also have the ability to access up to 120+ simultaneous wireless terminals, providing industrial users with flexible and stable connection options2

　　.

　　Internet of Things (IoT) devices

　　With the development of the Internet of Things, more and more smart devices need to be online continuously. 4G Wi-Fi 6 internal antennas can use 4G LTE as a backup link while maintaining local high-speed networks, ensuring that services are not interrupted even when networks are switched. For example, although the 5G external antenna BGS-910 provided by Fibocom is designed mainly for 5G, its support for 4G is also suitable for enterprises that want to upgrade to 5G in the future but still need to maintain the stability of existing 4G connections1

　　.

　　Design considerations

　　When designing 4G 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 adhesive, 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 conditions19

　　.

　　Optimize signal reception: Use advanced beamforming technology and smart antenna arrays to enhance signal reception quality, maintaining good communication performance even in the case of weak signals or interference.

　　In summary, 4G Wi-Fi 6 internal antenna solutions represent the cutting-edge development in the field of wireless communications. They not only meet the current market demand for high-performance networks, but also pave the way for future application scenarios. Whether it is an industrial or consumer product, the quality and technical specifications of the internal antenna will directly affect the quality of the end-user experience.
