* Do You Know Digital Band Selective Repeater?

    The radio management departments of most countries in the world usually allocate a frequency band of the spectrum resources to multiple operators, and a single operator can only use a part of the spectrum resources within this frequency band. For example, the full bandwidth spectrum resource is 75M of Band3 which defined by 3GPP. China's radio management department allocates Band3's spectrum resources to three Chinese operators. China Mobile obtains frequency resources of 25M bandwidth (1710~1735MHz/1805~1830MHz), and China Unicom obtains 30M bandwidth (1735~1765MHz/1830~1860MHz) spectrum resources, China Telecom obtains 20M bandwidth (1765~1785MHz/1860~1880MHz) spectrum resources.

    Digital Band Selective Repeater adopts digital filtering technology, uses A/D circuit to convert radio frequency signal into digital signal, and then uses programmable FPGA chip to run algorithm software to edit digital signal. One frequency band signal can be edited into multiple subbands, and then digital The signal is converted into a radio frequency signal, and each subband processed by digital filtering has good out-of-band suppression performance and will not interfere with each other. Therefore, installing a Digital Band Selective Repeater can simultaneously support the networks of multiple operators in the same frequency band.

    In addition, the equipment maintenance engineer can operate the monitoring software to turn on or turn off any subband of the Digital Band Selective Repeater, and can also flexibly set  bandwidth and frequency of any sub-band , and choose to support the network of a certain operator or multiple operators.
