NOTCHCELL 20W OPERATING MANUAL R-tron America, Inc. Page: 3 / 57 1. Overview NOTCHCELL repeater can be used in CDMA service hole spots like in-buildings, underground and tunnels to cover its service area. This repeater system designed for dual and simultaneous service, namely, it receives signals from the base station through donor antenna, amplifies the signals and re-transmits it to one or other mobile terminals. Also, it amplifies the signals which comes from mobile terminals through distributor antenna and re-amplifies it to base station. Using local OMT(Operation and Maintenance Terminal) which is connected between repeater control board and personal or laptop computer, it is possible to check or to control repeater status. With wireless modem which is in the repeater, it also enables to monitor Sprint WNMC(Wireless Network Management Center) in a remote place. Figure 1.1 NOTCHCELL repeater

Then, click “SET” button. ⑤ The value which is in isolation value pop-up window is current system isolation value. - When isolation value will be over 110, it is displayed as “Good”. When it is under 75, it is displayed as “Bad”. From 110 to 75, isolation value will be displayed. ⑥ Following the above procedures, you should set the isolation only one time.
NOTCHCELL 20W OPERATING MANUAL R-tron America, Inc. Page: 42 / 57 5.5.7 Gain & Attenuation Value Setting Following the above 5.5.6 isolation value setting, repeater gain can be set like below. Maximum repeater gain is 95dB. You can set attenuation value, controlling DL / UL ATTN. value which you are going to be output value. - Maximum Gain(dB) = Isolation Value(dB) – Margin (Margin ≥ 15dB) - Repeater Gain(dB) = User’s targeting Repeater Output Power(dBm) - Input power(dBm) - Attenuation Value(dB) = 95(dB) – Repeater Gain(dB) Figure 5.14 Gain setting window ► Note : How to set gain & attenuation value Example 1) Field isolation value is 100. Down Link Path repeater input value is -55dBm. User’s target output is 30dBm. ① Maximum available gain = 100(dB)–15(dB) = 85dB Therefore, maximum gain value is 85dB. ② Repeater Gain setting : Repeater Gain(dB) = 30(dBm) – (-55(dBm)) = 85(dB) When an user is going to use output 30dBm, repeater gain needs 85dB. ③ Attenuation Value setting : Attenuation Value(dB) = 95(dB) – 85(dB) =10(dB) Set “DL Attn” value as 10 in the GUI and click “SET” button which is located up-right end. On status mode, you can check “DL Attn” value is 10 and “DL Gain” value is 85.
NOTCHCELL 20W OPERATING MANUAL R-tron America, Inc. Page: 43 / 57 Example 2) Field isolation value is 100. Repeater input value is -65 dBm. User’s target output is 30dBm. ① Maximum available gain = 100(dB)–15(dB) = 85dB ② Repeater Gain setting : Repeater Gain(dB) = 30(dBm) – (-65(dBm)) = 95(dB) Current input level -65dBm. Therefore, when an user is going to use output; 30dBm, repeater gain needs 95dB. Considering maximum repeater gain;85dB, you can not set 30dBm as repeater output value. ► Note : Taking the above example 2, how to use repeater output as 30dBm. ① Change the direction of donor antenna for better input signal. (minimum -55dBm) ② Set antennas isolation value as 110.

Page: 44 / 57 5.5.8 ALC(Auto Level control) & Shut-Down Setting When you click “ALC” button which is located in left side menu bar, ALC, shutdown set and ON/OFF control pop-up window will be displayed. In the pop-up window, you can set downlink path output power like the above 5.5.7. When DL output value will be over than shutdown target set value, the repeater will be shutdown. Normally, shutdown target value will be set 3dB higher than ALC target value. About how to set shutdown count, shutdown on time and shutdown off time, please refer it to Appendix A, Chapter A.2.4. ALC. After input the value, click “SET” button for confirmation which is located in down side in the ALC Set pop-up window. Figure 5.15 ALC Set Pop-up Window
NOTCHCELL 20W OPERATING MANUAL R-tron America, Inc. Page: 45 / 57 ► Note : How to set ALC / Shutdown Target Value. ① When user set downlink path output power is 40dBm : About ALC, DL output power value is 40dBm. Therefore, set ALC target value as 40. ② Normal field situation, shutdown target value will be 43, 3dB higher than ALC target value. ► Note : How to work ALC and ASD If the ALC gets activated with system output exceeding ALC Target values, you need to use the USER ATT to adjust the output to meet the range of the upper settings. If the output exceeds the Attenuation range (30dB), the ALC FAIL alarm will occur. If the system output exceeds the Shutdown Target value due to lack of attenuation, then the ASD (Auto Shut Down) will be activated. If output exceeds the Shutdown target values and makes the repeater shut down, the repeater goes back to the active status after the ‘Shutdown-on’ time. If the output of the repeater is higher than the set target value, the repeater will be de-activated again after the set ‘Shut down-off’ time. The repeater repeats the process by the Shutdown count. If the output of the repeater still exceeds the target value after the repetitive work, the repeater will turn completely off.
