SUMMARY GSTR-2624D-SPR is an in-building solution for extending and improving WiMAX coverage area in Sprint network, providing better signal quality in small stores, manufacturing facilities, warehouses, etc. GSTR-2624D-SPR eliminates PN pollution to decreasing noise in Sprint’s BTS. # GRS-2624D-SPR Main Features # - Conversion type - DNC/IF/UPC integration module is implemented. - D/L & U/L S/W LNA - Sync Detection Module achieved sync.
SPRINT User Manual WIMAX 24dBm 2. 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.

SPRINT User Manual WIMAX 24dBm 2.2.2 Downlink Path GRS-2624D-SPR is basically designed to select 33MHz operational bandwidth from entire BRS bandwidth (188MHz). 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-2624D-SPR is implemented Bias, including LNA and HPA to functionate switching operation.

SPRINT User Manual WIMAX 24dBm 4.1.2 System set up 1) This equipment is basically wall mountable. 2) Installer will have to connect the power supply (after input power verification) and RF cable to the Repeater and then it will be ready to use. 3) For grounding, there is a grounding terminal in main power supply which will be plugged into power outlet. There is also a separate grounding terminal on the repeater which should be connected to the on-site grounding terminal to ensure proper grounding.
