• If Downlink/Uplink Output level is over +22dBm±1dB for 5 sec, Repeater Downlink and Uplink is Shutdown for 5 sec .
• This auto-shutdown algorithm can repeat 3 times
• Operator can adjust the times of ASD algorithm and duration of overpower shutdown period.

- Define : The distance of -65dBm received signal power to mobile handset
- Coverage area: Total 1,000m2 (at WCMA 850) - Connectable 2~4 service antennas - Considered -15dB as barrier loss
- Typically received signal sensitivity of mobile handset is -104dBm (GSM, DCS, CDMA, WCDMA)
- Coverage can be expanded with more service antenna
