Five-band Signal Booster For In-building 1.3 Functions I. Automatic Shut Down Mode Built-In Automatic Self-Monitoring Features for Anti-Oscillation: Automatic shut down mode operates when oscillation in the uplink and downlinks bands are detected and terminates potential harmful interference to wireless networks. • 1 minute non-operative mode on the first initial oscillation detection. • Default algorithm re-set mode as Auto S/D Mode is cleared • Complete shut off mode on the 5th repetition of auto shutdown mode status. All path are independently monitored and operated. II. Intermodulation Gain & Power Limit Control Uplink & downlink path formulates consistent link balance to regulate its input and output gain & power limits. Max UL gain < - 34dB – RSSI + MSCL (“ FCC 13-21,(i), 78p”) RSSI : Downlink composite received signal power at the donor port ( calculation value : DL Output – DL Gain ) MSCL : Mobile station and repeater service port minimum coupling Loss ( setting value ) All path gain limits are independently controlled III. ALC (Automatic Level Control) & AGC ALC is implemented to keep regular output power level for abnormal high input signal level. The regular output power makes possible high quality of phone call and data transfer. AGC is designed to automatically control gain. •Optimal Window Size (frequency range) sets the optimal level to increase faster response to modulated signal level changes on the basis of gain power control via signal input/output differential calculation all path gain limits are independently controlled IV. UL Path Automatic Sleep Mode If coverage is non-existent (Zero Area Zone), Uplink path shuts off as a harmful interference avoidance protocol and minimizes its power consumption. - 6 -

Five-band Signal Booster For In-building IV. UL Path Automatic Sleep Mode (continue ) • Automatic Turn Off / if UL PATH < -90dBm • Automatic Turn On / if UL PATH > -88dBm **All path gain limits are independently controlled V. Oscillation Auto Prevention • Degradation Protection: Detects potential performance degradation due to the overload signal feedback (over-heating) signals by isolation check & gain configuration. • Feedback Limits: Sets the operating range to exceeding high level signals from donor antenna (outside antenna) of a signal booster to service antenna (inside antenna) Booster Gain < Antenna to Antenna Isolation – 15dB If optimal isolation gain is not attained, Relevant path shuts off automatically. **All bands are independently controlled - 7 -
