NOTCHCELL 20W OPERATING MANUAL 5.5.5 Bandwidth & Band Setting When you click “Bandwidth” which is located left end in main window menu bar, you can see bandwidth and band configuration pop-up window. Then, set the band and bandwidth, considering the field condition. (See the following table 5.
NOTCHCELL 20W OPERATING MANUAL ④ Click “SET” button to fix bandwidth and band. ⑤ Click “EXIT” button for exiting bandwidth pop-up window. R-tron America, Inc.
NOTCHCELL 20W OPERATING MANUAL 5.5.6 Isolation Checking When you click “Isolation” button which is located left side menu bar, the following pop-up window which is for isolation check between donor and distributor antennas will be opened. “Isolation pilot power” value stands for isolation antenna value. Figure 5.13 Isolation checking window ► Note : How to check isolation. ① Considering your location, check whether the repeater bandwidth and band are properly set. ② Select “Isolation” in the menu bar.
NOTCHCELL 20W OPERATING MANUAL 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. - Maxi mum 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.
NOTCHCELL 20W OPERATING MANUAL 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.
NOTCHCELL 20W OPERATING MANUAL 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.
NOTCHCELL 20W OPERATING MANUAL ► 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.
