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.

-1] Isolation test
1] Isolation test1] Isolation test
1] 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.

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.
