Notifications to LED indicators:
For RP 12 GSM / CDMA
For RP 12 GSM / CDMA there are 2 LEDs on each RP12-GSM and RP12-CDMA
repeaters ,One is power LED and the other one is alarm LED.
For power LED, it glows when the input power is within 110/220V ±20% ,and power
switch is on.
For alarm LED, one can observe three colors, and each one has distinct meanings
as listed below.
‧Green : Indicates normal operation.
‧Orange: Indicates the AGC(Auto Gain Control) has activated .
‧Red : Indicates the I/O power is too high to be depressed by the AGC and the
repeater is then saturated which might damage itself.

Notifications to LED indicators:
For RP 12 DCS / WCDMA
For RP 12 DCS / WCDMA there are 3 LEDs on each repeaters: one LED
indicates the status of the repeater and the other 2 are for uplink/downlink
power.
L1 : Status indicator , it should illuminate green when the repeater is working
properly.
L2 : Downlink indicator , each green ,yellow or red light represent different alarm.
L3 : Uplink indicator , each green ,yellow or red light represent different alarm.

–RP12WCDMA repeater is dedicated for indoor coverage, such as
small offices, houses, basements, and public places.
–The amount of service antennas can be one to four; omni or panel.
–The donor antenna is recommended to be mounted at below 7
th
floor.
–Donor signal strength and quality must be good enough. (refer to the
slide of “Selection of Donor Signal”)

Since most of mobile phones nowadays haven’t connecting port of external antenna,
directly measured by a engineering-mode mobile phone is also acceptable.

WCDMA – Three Criteria as below descriptions & formulas
1. Signal Strength — RSCP of donor signal is better ranged from -60 to -70 dBm. Depends)
2. Signal Quality — Ec/No of donor signal must be equal or larger than -7 dB.
3. Signal Stability — RSCP of donor signal must be equal or larger than neighbor signals by 6 dB.
Remark
AS_CPICH: Pilot Channel in Active Set i.e., Serving Cell)
MS_CPICH: Pilot Channel in Monitor Set i.e., Neighbor Cell)
Total_Power: Total power including CPICH, Control &
Traffic Channels for some frequency.
