Directional MIMO 4x4 antennas

　　Directional MIMO 4x4 antenna: precisely focused communication enhancer

　　In the field of wireless communications, directional MIMO 4x4 antennas have become key equipment for improving communication quality and efficiency with their unique advantages, and are widely used in various scenarios.

　　Technical principles and characteristics

　　Combination of MIMO basics and directional radiation

　　MIMO (Multiple Input Multiple Output) technology improves communication performance through multi-antenna transmission and reception. The directional MIMO 4x4 antenna system is equipped with four transmitting and four receiving antennas, which can process four independent data streams at the same time. Unlike omnidirectional antennas, directional MIMO 4x4 antennas radiate signals in a specific direction, greatly enhancing the signal strength and transmission distance in that direction.

　　Spatial multiplexing and diversity gain

　　Spatial multiplexing technology enables the transmitter to split the original data and send it simultaneously through four transmitting antennas. The receiver uses algorithms to separate and reassemble the sub-data streams to increase the data transmission rate. For example, in 5G communications, compared with traditional single-antenna systems, the data throughput can theoretically be increased to four times. Diversity technology uses the differences in the fading characteristics of signals received by different antennas to obtain multiple signal copies from four receiving antennas. By selecting algorithms such as merging and maximum ratio merging, the probability of deep signal fading is reduced and the reliability of received signals is improved. In complex urban environments, it can effectively improve signal quality and reduce communication interruptions.

　　Product Types and Features

　　Flat-panel directional MIMO 4x4 antenna

　　Flat-panel directional MIMO 4x4 antennas are composed of multiple vibrators in an array with a compact structure. For example, the WMM 4G (G)-6-60 model for 4G and 5G networks integrates four independent broadband component components into a single housing, with a peak gain of 6dBi in the 617-960MHz band and a peak gain of 9dBi in the 1710-6000MHz band. The antenna has an IP66 protection level and is suitable for outdoor use. It is equipped with a wall or mast mounting bracket and a low-loss double-shielded cable to reduce exposed connector joints for easy installation and cable management. It is commonly used in point-to-point communication and key coverage of specific areas, such as wireless monitoring networks in remote mountainous areas. It can accurately target the target area to achieve long-distance and high-stability data transmission.

　　Parabolic Directional MIMO 4x4 Antenna

　　Parabolic Directional MIMO 4x4 Antenna uses the parabola reflection principle to focus the signal, with extremely high gain, up to 10dBi or more. Its design is complex, and the parabola shape, antenna position and angle need to be precisely adjusted to achieve the best focusing effect. It is commonly used in professional communication fields with strict requirements on signal strength and directionality, such as long-distance microwave communication and special industrial data transmission. In some large industrial plants, it is used to connect communication equipment in different areas to ensure reliable data transmission.

　　Application Field

　　Mobile Communication Network

　　In 4G and 5G mobile communication network base stations, directional MIMO 4x4 antennas can simultaneously transmit data with multiple user devices in multiple streams. In urban areas with dense high-rise buildings, base stations use directional MIMO 4x4 antennas to accurately radiate signals to user-concentrated areas, improve spectrum efficiency, meet the high-speed data service needs of a large number of users, and reduce network congestion and freezes. For example, in crowded places such as large shopping malls and stadiums, users can smoothly play videos, play online games, and make mobile payments.

　　Wireless Local Area Network (WLAN)

　　Enterprise-level wireless access points use directional MIMO 4x4 antennas, which can concentrate signals to cover office spaces according to the layout of office areas, providing high-speed and stable network connections for employees' laptops, smartphones, tablets and other devices. For example, in open office areas, directional antennas can reduce signal interference, improve network performance, ensure that employees can smoothly carry out video conferencing, file sharing, cloud storage access and other tasks, and improve office efficiency.

　　Internet of Things (IoT)

　　In smart factories, various sensors, actuators, and robots communicate with gateways through directional MIMO 4x4 antennas to achieve real-time monitoring and automated control of the production process. The production data collected by sensors can be quickly and stably transmitted to the gateway and management system to ensure accurate and efficient production. In the field of intelligent transportation, Internet of Vehicles devices use directional MIMO 4x4 antennas to communicate with roadside infrastructure or other vehicles, support vehicle intelligent driving assistance, real-time acquisition of traffic information and other functions, and improve traffic safety and smoothness. For example, on highways, vehicles communicate with roadside units through directional antennas to obtain road condition information and optimize driving routes.

　　With the development of wireless communication technology, the demand for high-speed and stable communication continues to grow. Directional MIMO 4x4 antenna technology will continue to innovate, play a key role in more emerging fields, and promote wireless communication technology to a new level.
