Leading Edge Technology Signal Booster

USHR-781921-5B signal booster designed to boosts cellular signal for area
prone to weak coverage area. Its coverage is on 800 MHz, 1900MHz, AWS and 4G
Verizon and AT&T 700 MHz as well as 4G Sprint. To allow installer to optimize
signal and gain control each frequency band, it has control knobs.

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.

Five-band Signal Booster For In-building

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

Max UL gain < - 34dB – RSSI + MSCL (“ FCC 13-21,(i), 78p”)

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

IV. UL Path Automatic Sleep Mode (continue )

**All path gain limits are independently controlled

V. Oscillation Auto Prevention

Booster Gain < Antenna to Antenna Isolation – 15dB

• Automatic Turn Off / if UL PATH < -90dBm

• Automatic Turn On / if UL PATH > -88dBm

• 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)

If optimal isolation gain is not attained, Relevant path shuts off
automatically.

**All bands are independently controlled
