    Amplitec S37T-Bxxx series digital multi-carrier public safety and emergency communication wireless repeater is a communication device that uses software radio technology to digitally filter RF signals through AD/DA and then restore them to RF signal. It is used to extend the coverage of TETRA, DMR, PMR, P25 and other public safety and emergency communication systems.

    The S43T series digital multi-carrier public safety and emergency communication wireless repeater adopts a high-quality aluminum alloy die-casting shell case, reaching IP65 protection level, and can be mounted on indoor walls or outdoor poles. The equipment is equipped with one USB local monitoring interface and two N-Female RF interfacesIn addition, it has a built-in SIM card slot. After inserting a 4G SIM card, you can wirelessly access the NMS network management for remote monitoring.

    The Down Link of the S37T-Mxxx series repeater wireless  receives base station's RF signal such as TETRA, DMR, PMR, P25 through the donor antenna, converts it into a digital signal through AD, and then converts it into an RF signal through DA after filtering by FPGA, and then transmits it to the coverage area through the service antenna. On the contrary, the Up Link receives the communication terminal RF signal through the service antenna, converts it into a digital signal through AD, and then converts it into an RF signal through DA after filtering by FPGA, and then transmits it back to the base station through the donor antenna after amplification.

    The S37T-Mxxx series repeaters have the following models suitable for public safety and emergency communication systems in various frequency bands. Other frequencies can also be customized according to customer needs.
