BackThe remote unit

Product introduction:In the MDAS system, the remote unit (RU) converts the digital signals sent by the extended unit into radio frequency signals to achieve the wireless coverage of DCS, WCDMA and fdd-lte. At the same time, the received uplink rf signal is converted into digital signal and transmitted to the extension unit. According to the application scenarios of the far-end unit (RU), it can be divided into "antenna monomer" and "antenna external connection type".
