4g dtu transparent transmission module
The 4G DTU transparent transmission module developed by Chengdu Zongheng Intelligent Control is a product that supports two-way transparent transmission. Users do not need to care about complex protocols. The product is two-way transparent transmission and only requires simple configuration. At the same time, the product is 4G full network, supporting all domestic operator networks. The communication module uses CTA1 series modules, which is highly cost-effective. A 4G DTU transparent transmission module is as low as 139 yuan. The product adopts guide rail installation, which is easy to install and takes up little space.

Other explanations
Attualmente la tecnologia di comunicazione mobile è dominata dalla tecnologia 4G. La tecnologia 3G non è più in grado di soddisfare le esigenze commerciali di molti utenti. La tecnologia 5G è ancora in fase di ricerca e sviluppo, per cui i vantaggi della tecnologia 4G sono del tutto scoperti. La tecnologia 4G è mainstream, quindi dobbiamo studiare le sue tecnologie chiave di conseguenza. Di seguito sono riportate le tecnologie chiave della tecnologia 4G.
Orthogonal Frequency Division Multiplexing Technology (OFDM) OFDM technology is actually a type of multi-carrier modulation. Its principle is to divide the channel into several orthogonal sub-channels and convert high-speed serial data signals into low-speed parallel sub-data signals. The sub-data The signal is modulated and transmitted on these orthogonal sub-channels. Orthogonal signals can be separated by using correlation demodulation technology at the receiving end. Due to the use of orthogonal channels, this reduces mutual interference between sub-channels. The use of OFDM technology for transmission can improve spectrum utilization, enhance the signal’s anti-fading ability, reduce inter-symbol interference, and increase the data transmission speed.
The core idea of software radio technology is to construct an open, standardized and modular universal hardware platform, and use software to complete various functions such as working frequency band, modulation and demodulation type, data format, encryption mode, communication protocol and so on. Broadband A/D and D/A converters are placed as close as possible to the antenna to develop a new generation of wireless communication systems that are highly flexible and open.
