nd
Step: Detection of Channel Parameters
It supports up to 5 carriers (default working bandwidth is 20MHz which can be
customized) in the carrier list which can be customized
customized) in the carrier list which can be customized
List from Intelligent Carrier Scanner: Click this button to get detailed
information of all carriers within the carrier list
No: Carrier number
Frequency: Center frequency of the carrier in MHz
PSS: Primary Synchronization Signal
SSS: Secondary Synchronization Signal
QoS
Frequency: Center frequency of the carrier in MHz
PSS: Primary Synchronization Signal
SSS: Secondary Synchronization Signal
QoS
: Quality of Service which is defined by Helios. It’s based on 10 times of
statistics, the value in QoSbox means the successful times to get SSS code.
Higher QoS, better quality of service
Higher QoS, better quality of service
Rx Level: Timeslot 1 input power in dBm
Special Subframe: 0 (normal CP) or 1 (Extended CP)
Uplink/Downlink Allocation: Uplink/Downlink allocation, 0~6
Cyclic Prefix: 0 (normal CP) or 1 (Extended CP)
Operator Code: PLMN code of the operator
Set: Click on target carrier and click Set to lock on it

The 3rd Step: Set the Synchronization Threshold
If the input power is too weak to ensure normal synchronization, then the Pico
Repeater cannot be normal working, in such
Repeater cannot be normal working, in such
case, it’s necessary to switch off the Pico
Repeater to avoid interference
Synchronization threshold: If the Rx Level is less than the synchronization
threshold (default -90dBm, configurable), it will switch off the Pico Repeater
Value: Minimum Rx Level for synchronization in dBm
Set: Input minimum Rx Level in Value box and click Set to modify the threshold
