OverviewOverviewOverviewOverview ş [[[[FigureFigureFigureFigure 1111----1111]]]] LGE NOTCHCELL Repeater LGE NOTCHCELL Repeater LGE NOTCHCELL Repeater LGE NOTCHCELL Repeater LGE NOTCHCELL repeaters are used to fill out uncovered areas in CDMA mobile systems, such as base station fringe areas, road tunnels, business and industrial buildings, etc. A NOTCHCELL repeater receives signals from a base station, amplifies and retransmits the signals to mobile stations. Also it receives, amplifies and retransmits signals in the opposite direction. Both directions are served simultaneously. To be able to receive and transmit signals in both directions, the repeater is connected to a donor antenna directed towards the base station and to a distributor antenna directed towards the area to be covered. Control of the repeaters is performed using a desktop or notebook loaded with the LGE OMT, Operation and Maintenance Terminal, which can communicate with the repeaters either locally or remotely via wireless data modem. Remote operation can be performed either via CDMA net. To be able to control many LGE NOTCHCELL repeaters in common, there is a Sprint EMS center.

30/39 3) Cautions in the installation of the feeder cable  Install the cable in the shortest distance, if possible, between the Antenna and the repeater.  The selected cable path must not affect the appearance of the building or the station.  When installing the repeater in a general building, select the cable path in which the feeder cable is not damaged by outsiders or other factors.  Select the feeder cable path with less curves and attach the feeder cable tag.  The VSWR in the power feeder must not higher than the standard at the completion of the work.  Do not use the damaged feeder cable. 4) Installing/ tying the feeder cable The installation of the feeder cable is sensitive to the bend radius and humidity. Therefore, the following regulations shall be observed.  Maintain the minimum bend radius. (Higher than the standard presented by the manufacturers)  he cable must not be entangled.  Do not apply excessive force to the feeder cable to prevent bent insulated conductors or dug coverings.  The outer connecting part of the connector must be waterproof.  Tie the cable at every 50cm.  Tie the cables firmly so that they shall not be affected by external impact.  Use the bending machine if required to bend the cable.  Cut the feeder cable with a hacksaw and clean out the cut area. 5) Feeder cable connector The followings shall be observed at the assembly of the feeder cable connector.  Cut the feeder cable carefully to prevent the inflow of water, steel and lead strip, or dust.  Clean the connector and the gasket connector to keep airtight.  Do not apply excessive force nor work in a hurry.  Avoid connection work at the time of rain. If it is unavoidable, be careful to prevent the inflow of rain to the connecting part of the feeder cable connector.  Install the 1/2” feeder cable by inserting it into the shield cable and 36mm flexible conduit. In case of the 7/8”feeder cable, install the cable only.

OperatioOperatioOperatioOperationnnn 4.1 Isolation test procedure of Antenna [Figure 4[Figure 4[Figure 4[Figure 4----1] Isolation test1] Isolation test1] Isolation test1] Isolation test 1) Set-up the equipment as shown in [Figure 4-1] Isolation test 2) Set up the analyzer for the highest possible sensitivity (more than 100dBm) for 0dBm source-power. 3) Set the analyzer to ‘peak search mode’. 4) After calibrated cable loss between Measurement Equip and Antenna, set the output-power of the generator to 0 dBm. 5) Turn on Signal Generator Output 6) Measure the Antenna Isolation, using spectrum analyzer. The minimum isolation is the highest value of the curve (excepting carriers transmitted by surrounding BS). 7) Change measurement-ports to check for the opposite direction by repeating the measurement procedure. 8) Repeat the test for the opposite path of the repeater. Step (1) to (7). Isolation per carrier frequency is worse value.
37/39 4.1.1 Power-up sequence 1) Confirm whether LGE NOTCHCELL Repeater was linked normally with Donor Antenna and Distributor Antenna or not. 2) Confirm whether Main box and PSU box's AC input and DC connection cable were connected normally. 3) Turn AC input switch of PSU Box interior on. 4) Confirm whether various LED (AC Fail, DC Fail, and BATT . Fail)s of PSU box interior are normally. (Normal: Yellow, abnormal: RED) Only, BATT. Fail LED does normal action in following condition.  PSU box's DC IN Connector has to be linked to Battery.  BATT . Switch has to be established by ON. 5) Confirm state of ARCU board's POWER, RUN, WNMC, GUI, OPERATING LED of Main box interior. 6) POWER: When +5V is powered ARCU board, Yellow LED is lighted. 7) RUN: When ARCU board's CPU acts normally, Yellow LED twinkles. 8) WNMC: When send and reveive Data between ARCU and ARIU's Modem, Red LED twinkles. 9) GUI: When receive Data from ARCU board in monitoring PC, Yellow LED twinkles. 10) OPERATING: Orange LED twinkles by 1 second cycle after normal booting of ARCU board. 4.1.2 Repeater control application 1) Execute LGE NOTCHCELL's Local GUI program "SPCS gui.exe". 2) Connect Local OMT port and PC's data communication port using communication cable (MS 10SL _3 pin to D-sub _9 pin type). 3) After Local GUI does Loging, confirm whether data communication between Repeater and PC is normal. 4) Confirm whether Downlink path's RSSI satisfies dynamic range (- 55dBm ~ - 30dBm). 5) When set Downlink path’s maximum output and maximum gains, consider and decide RSSI and antenna isolation. Also, Repeater's maximum gains establishment considers 15 dBs Margin in isolation of antenna. Repeater’s maximum gain = Antenna isolation – 15dB (Margin) 6) After decide Downlink path's output and gains according to user's request, do DL PA toggle switch enable in Local GUI's control window. 7) When inspect Downlink path's output waveform, inspect using Monitoring port (SMA-Female type) on Main box’s right side lower column.
38/39 8) When set Uplink path’s maximum output and maximum gains, consider and decide RSSI and antenna isolation. Also, Repeater's maximum gains establishment considers 15 dBs Margin in isolation of antenna. Repeater’s maximum gain = Antenna isolation – 15dB (Margin) But, in the case of Uplink path, when set output and gains because it is no fixed input level, set on the basis of Noise level. Up Link Gain = 113 [dBm] + BS_ Noise Level [dBm] – Repeater_Feeder cable loss [dB] – Donor ant. Gain [dBd] – Path Loss [dB] – BS_Ant. Gain [dBd] – BS_Feeder cable loss [dB] Air Loss (dB) = 20log (1/λ) + 20log (4π) + 20log (d) Only, preceding formula recommands to apply in Line of site section of BS and Repeater. However, can be different from noise level and theoretical arithmetic level by change of RF environment. 9) When inspect Uplink path's output waveform, inspect using Monitoring port (SMA-Female type) on Main box’s left side lower column. 10) In Local GUI's control window, consider site situation about items below and establish properly.  Parameters to act Alram that correspond to each input/output  Parameters to act ALC function  Parameters to act Shutdown function 11) After input each setting value in Local GUI's control window, moving by monitor window, confirm alarm's existence and nonexistence. 12) Erase alarm that happen at setup process in Local GUI's History window.
