SUMMARY GRS-1924R-SPR is an Digital RF repeater, which improves PCS network. GRS-1924R-SPR receives RF signal from BTS and transmits it to the blanked and shadowed area, thus providing and improving voice and image data services. GRS-1924R-SPR’s goal is to support BTS’s functions proportionately. GRS-1924R-SPR communicates with BTS wirelessly, thus saving additional costs for its maintenance. GRS-1924R-SPR consists of RF/IF part module, Digital Filter module, and I/O & Control module divisions, which are supplied with Alarm LED, thus providing quick and easy maintenance and troubleshooting of the repeater. This manual describes in general structure of GRS-1924R-SPR, its application, maintenance and troubleshooting, installation and operation etc. Abbreviation PCS : Personal Communication System RF: Radio Frequency BTS: Base Transceiver Station IF: Intermediate Frequency I/O : Input/Output Sprint User Manual 3G Indoor Repeater 4/20 2. System Configuration 2.1 GRS-1924R-SPR Service Organization GRS-1924R-SPR decreases blanked and shadowed areas and extends cell coverage by re-trans mitting signal. The signal is received from BTS via Antenna directly, thus excluding additional ex penses for signal transmission (like cabling). Service organization of CDMA In-building RF repeat er is shown at the picture below. Donor Antenna is directed to BTS, and being divided at Servic e Antennas are installed in the building and parking place. Pass Loss should be taken into consi deration while dividing and cabling. <Pic.1> US PCS 1900 Service Organization Sprint User Manual 3G Indoor Repeater 5/20 2.2 System Design and Operation 2.2.1 System Design <Pic.2> GRS-1924R-SPR Repeater Sprint User Manual 3G Indoor Repeater 6/20 <Pic.3> Internal Design NO DESCRIPTION ① CAVITY FILTER - (Frequency Filtering) ② CONVERTER MODULE - (Frequency Conversion) ③ PSU MODULE(RS-100-9) - (Converter, LED, NMS Power Supply) ④ PSU MODULE(RS-35-12) - (EMB Power Supply) ⑤ I/O BOARD - (Input/Output Board) ⑥ NMS BOARD - (System Control Board) ⑦ DIGITAL FILTER - (Digital Filtering) ⑧ ETHERNET BOARD - (Web UI Board) Sprint User Manual 3G Indoor Repeater 7/20 ⑦ ①② ③ ④ ⑤ ⑥ ⑦ ①② ③ ④ ⑤ ⑥ <Pic.4> Outside Port Design NO DESCRIPTION ① DONOR ANT PORT ② SERVER ANT PORT ③ POWER SWITCH PORT ④ AC POWER PORT ⑤ CLI MONITOR PORT ⑥ ETHERNET PORT ⑦ DC POWER PORT Sprint User Manual 3G Indoor Repeater 8/20 2.2.2 Downlink Path Downlink and Uplink Gain Budgets have similar structure. In case of Downlink Path, RF signal is received from Donor Antenna, and through FWD division, then the signal is transferred to IF division, where desirable Band is selected by Digital Filter. Selected Band is transferred to RF division again, and through FWD PAM, after that the signal is transmitted to User through Server Antenna. Two attenuators use for AGC compensation. AGC attenuation range is 40dB. <Pic.5> Downlink Block Diagram Sprint User Manual 3G Indoor Repeater 9/20 2.2.3 Uplink Path Uplink Path is similar in structure to Downlink Path. In case of Uplink Path, RF signal is received from Server Antenna, and through RVS division, then the signal is transferred to IF division, where desirable Band is selected by Digital Filter. Selected Band is transferred to RF division again, and through RVS PAM, after that the signal is transmitted to BTS through Donor Antenna. Two attenuators use for ALC compensation.

Description of Tests(Conducted) Conducted Emissions The line-conducted facility is located inside a 3.6 m(W) × 4.6 m(L) × 2.2 m(H) shielded enclosure and meets the requirements of ANSI C63.4 The EUT was placed on a non-conducting a 1 m × 1.6 m table which is placed 40 ㎝ away from the vertical wall and 1.5 m away from the sidewall of the shielded room. The EUT is powered from a Rohde & Schwarz 50Ω/50μH Line-impedance Stabilization Networks (LISNs) and the peripheral equipment is powered from the Rohde & Schwarz LISN. All interconnecting cables more than 1 meter were shortened to 40 ㎝ length by non-inductive bundling (figure eight fashion). Sufficient time for the EUT, the peripheral equipments and test equipment were allowed in order for them to warm up to their normal operating condition. The RF output of the LISN was connected to the spectrum analyzer to determine the frequency producing the maximum electromagnetic emission from the EUT. The EUT, peripheral equipment and interconnecting cables were arranged and manipulated to maximize each electromagnetic emission. Each emission was maximized by: switching power lines varying the mode of operation or resolution; scrolling H pattern to the EUT and/or peripheral equipment; whichever determined the worst-case emission. Each electromagnetic emission was listed on Table 1. Conducted FCC Class A. EMI CONDUCTED EMISSIONS CISPR 22 CLASS A Limits dB㎶ Freq.

Description of Tests (Radiated) Radiated Emissions Preliminary measurements were made indoors at 3-meter using broadband antennas, broadband amplifiers, and spectrum analyzers to determine the frequency producing the maximum electromagnetic emission. Appropriate precaution was taken to ensure that all electromagnetic emission from the EUT were maximized and investigated. The spectrum was scanned from 30 to 1000 ㎒ using a Tri-log antenna and above 1 ㎓ linearly polarized horn antennas were used. Final measurements were made outdoors at 3-meter or 10-meter test range using Tri-log antenna. The test equipment was placed on a wooden table situated on a 1.5 m × 2 m area adjacent to the measurement area. Sufficie…
