Product Descriptions
E90-DTU (230N37)is a data transmission station with extremely advanced ultra-narrow band modulation technology, which greatly improves the communication distance and communication stability. Power amplifier (PA) andlow noise amplifier (LNA) are built in the original foundation, so that the maximum transmitting power reaches 5W and the receiving sensitivity is also improved to a certain extent. Compared with the products without power amplifier and low noise amplifier, the overall communication stability is greatly improved.
Because E90-D'TU (230N37) adopts 230MHz frequency band, it not only ensures the penetrability, but also greatly improves the diffraction ability, making it the best choice for complex and multiple obstacles. The station works in 230MHz frequency band, and the communication distance can reach 15km. Wireless digital radio as a medium of communication, as well as optical fiber, microwave, open wire, there is a certain scope of application: it provides some special conditions, private network monitoring signals in real-time and reliable data transmission, low cost, easy installation and maintenance, diffraction capability is strong, flexible network structure, the coverage is far characteristic suitable for some more and occasions, such as dispersion and complex geographical environment with PLC. RTU, rain gauge, level gauge and other data terminal is connected.
