SYSTEM STRUCTURE 2.1 Network structure for WIMAX Indoor RF Repeater Below picture shows a Network structure for WIMAX Indoor RF Repeater in a real site. Donor ANT takes a position on the direction to BTS which be linked, and Server ANT is available to be located in designated area for service by using RF cable deployments and dividers as blow. One thing that we consider is Path losses between Repeater port and ANT in case of dividing by dividers and RF cables. They should be equally managed.

Repeater would smartly select actual Sprint operational bandwidth such as 2502~2568MHz (ABCD), 2624~2690MHz (EFHG) using local frequency without interfering into in-band. To discriminate Tx / Rx circuit, GRS-2630D-SPR is implemented Bias, including LNA and HPA to functionate switching operation. In the LNA, SPDT switch is implemented not only to improve Tx/Rx separation, but to protect Rx circuits, when antenna is open.
