    2023-11-02 434

    With the continuous development of communication technology, wireless communication has become an essential part of People's Daily life. Among various wireless communication technologies, WiFi has been widely used because of its high-speed and convenient data transmission. In this paper, the construction of WiFi module of 9km wireless communication module is introduced in detail, and the technologies supported by LR-WiFi, LDPC and MIMO are discussed.

    9km wireless communication module wifi module construction supports LR-WiFi, LDPC, MIMO

    First, the construction of 9km wireless communication module WiFi module


    9km wireless communication module WiFi module is a highly integrated wireless communication equipment, mainly including baseband processing, RF transceiver, power amplification and filtering and other key parts.


    Baseband processing unit


    The baseband processing unit is the core of the WiFi module, which is mainly responsible for the scheduling of data transmission, signal encoding and decoding, and signal modulation and demodulation. In addition, it is also responsible for the interaction with the terminal device, including task scheduling, interrupt handling, and so on.


    Rf transceiver


    The RF transceiver is the key part of the WiFi module, which is responsible for modulating and demodulating the baseband signal to realize the RF signal transceiver. In the transmission process, the RF transceiver converts the baseband signal into an RF signal and amplifies it through a power amplifier, then filters out the clutter and transmits it through the antenna. In the receiving process, the RF transceiver filters and amplifies the RF signal received by the antenna, and then demodulates it into a baseband signal and transmits it to the baseband processing unit.


    Power amplifiers and filters


    The power amplifier and filter are the auxiliary components of the WiFi module, which together determine the quality and transmission distance of the signal. The power amplifier is responsible for amplifying the RF signal to increase the strength and transmission distance of the signal. The filter is responsible for filtering out the clutter and noise in the signal to reduce signal interference and distortion.


    Second, support LR-WiFi, LDPC, MIMO and other technologies


    The 9km wireless communication module WiFi module supports a variety of advanced technologies, which further improve the performance and reliability of wireless communication.


    LR-WiFi technology


    LR-WiFi technology is a new type of wireless communication technology, which realizes long-distance WiFi connection by introducing long-distance wireless communication module. Compared with traditional WiFi technology, LR-WiFi technology has higher sensitivity and longer transmission distance, making WiFi connection can be applied in a wider range of scenarios.


    LDPC technology


    LDPC technology is a kind of error-correcting coding technology, which can correct the wrong data by adding redundant information to the data. In WiFi communication, because of the complex and changeable channel environment, data transmission errors often occur. The application of LDPC technology can reduce data transmission errors to a large extent and improve the reliability of data transmission.


    MIMO technology


    MIMO technology is a kind of multi-antenna technology, which realizes the combination of spatial multiplexing and signal diversity by using multiple antennas simultaneously at the transmitting and receiving ends. In WiFi communication, the application of MIMO technology can greatly improve the data transmission rate and reliability. At the same time, MIMO technology can also enhance the coverage of the signal through multi-path propagation.


    In short, 9km wireless communication module WiFi module as a high-performance wireless communication equipment, its structure and supported LR-WiFi, LDPC, MIMO and other technologies jointly determine its performance and reliability. With the continuous progress of science and technology and the continuous expansion of application scenarios, we can foresee that more advanced wireless communication technologies and equipment will continue to emerge in the future, bringing more convenient and efficient data transmission experience to people's lives.
