4G antenna communication technology is the fourth-generation mobile information system. It is a better improvement in 3G technology.

Compared with 3G communication technology, 4G antenna communication technology has a greater advantage in that it combines WLAN technology and 3G communication technology.

A good combination makes the image transmission speed faster and makes the quality of the transmitted image and the image look clearer.

The application of 4G antenna communication technology in smart communication devices allows users to surf the Internet faster, with speeds up to 100Mbps.

4G antenna communication technology is based on the previous 2G and 3G communication technologies, and some new technologies have been added to it to make the wireless communication signal more stable, increase the data transmission rate, and have smoother compatibility and higher communication quality.

Moreover, the technology used in 4G antenna communication is also more advanced than 2G and 3G antenna communication, making information communication faster.

Based on 3G antenna technology, 4G antenna technology is continuously optimized, upgraded, and innovatively developed. It integrates the advantages of 3G antenna technology and has derived a series of inherent characteristics of its own, with WLAN technology as the development focus.

The innovation of 4G antenna communication technology gives it a greater competitive advantage compared with 3G antenna communication technology.

First of all, 4G antenna communication can realize high-definition transmission of original images and original videos in the transmission of pictures and videos, and the transmission quality is comparable to that of a computer;

Secondly, using 4G antenna communication technology, the speed of downloading software, files, pictures, audio, and video can reach up to tens of megabytes per second, which is not possible with 3G antenna communication technology, and it is also a significant advantage of 4G antenna communication technology;

This fast download mode can bring us a better communication experience, and also facilitate the download of learning materials in our daily study;
At the same time, in the context of the rapid and convenient development of the network, users have also put forward higher requirements for the cost of traffic.

From the current 4G network communication charges, the price is higher, but major operators have also introduced corresponding services for different groups. Traffic preferential policies can meet the needs of different consumer groups.

4G antenna key technology

4G antenna OFDM technology

FSK has a bit of anti-interference. The encoding uses a unipolar non-return-to-zero code.

When the code sent by the transmitter is 1, it means it is at high frequency, and when the code sent is 0, it means it is at low frequency. If the code sent is 1011010, the waveform formed by the code will show periodic fluctuations.

Signals transmitted using OFDM technology will have a certain overlap, and technicians will analyze it according to the processor, and divide different information categories according to the subtle difference in frequency, so as to ensure the stable transmission of digital signals.

4G MIMO antenna technology

4G MIMO antenna uses mapping technology.

First, the transmitting device sends the information to the wireless carrier antenna. After the antenna receives the information, it quickly compiles it, compiles the compiled data into digital signals, and sends them to different mappings. Zone, and then use diversity and multiplexing modes to fuse the received data signals to obtain hierarchical gain.

4G Smart antenna technology

Smart antenna technology is a technology that effectively combines time division multiplexing and wavelength division multiplexing technology. In 4G antenna communication technology, smart antennas can achieve omnidirectional coverage of the transmitted signal.

The coverage angle of each antenna is 120°, in order to ensure full coverage, at least three antennas will be installed at the transmitting base station.

In addition, smart antenna technology can adjust the transmitted signal to obtain the gain effect and increase the transmission power of the signal. It should be noted that the gain adjustment here is not related to the radiation angle of the antenna, but only increases the transmission on the original basis. Power is all.

4G antenna SDR technology

Software radio technology is one of the commonly used technologies in radio communication technology.

The technical idea is to bring the broadband analog-to-digital converter or the digital-to-analog converter close enough to the radio frequency antenna, write specific program codes to complete frequency band selection, and perform quantitative analysis after sampling and transmitting information, which can realize the differentiated selection of channel modulation methods and complete different security structure, the choice of the control terminal.

4G antenna EPON network architecture

The 4G EPON network structure consists of three parts in total. There are terminal equipment, switching equipment, and power grid office equipment between users and communication providers.

There are a total of 64 transmission frames in the transmission line, and each transmission frame includes 24 bytes, that is, 192 bits of data.

The maximum transmission distance of this transmission structure can reach 20 kilometers. The EPON transmission line is divided into upper and lower layers. The upper line uses time-division multiplexing for transmission.

The switching equipment transmits different information to the terminal equipment at different transmission times to avoid confusion of various information, and the lower line uses broadcast transmission for real-time transmission. The terminal equipment screens different information and selects the information needed in real-time to receive.

4G antenna TD-LTE network architecture

4G antenna TD-LTE mainly plans network information distribution from three levels. The core layer is to increase the speed of data transmission and reduce the transmission time from the user end to the base station; the business layer is to complete data processing and exchange.

In 4G antenna communication In the business, there is a lot of data information that needs to be transmitted. The business layer can effectively increase the original transmission rate and alleviate the delay of receiving data; the transmission layer is mainly used to reference the passive optical network to achieve splitting between the OLT and the NOU.

Among them, the ONU should adopt the dual PON transmission mode at the upstream port, forming a protection network near the central office equipment to avoid data loss.
