Product Descriptions
E90-DTU (230N33) is a data transmission station with extremely advanced ultra-narrow band modulation technology, which greatly improves the communication distance and communication stability. On the basis of the original built-in power amplifier
(PA) and low noise amplifier (LNA), so that the maximum transmission power reaches 2W at the same time the receiving sensitivity has also been improved to a certain extent, in the overall communication stability than no power amplifier and low noise
amplifier products greatly improved.
Because E90-DTU (230N33) 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, with communication distance up to 8km. 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.
