ACE Antenna Corp.
US HR- 0819SS features and functions are described below.
3.1 Operation and Monitoring Functions
3.1.1 This unit uses 3 LED display to distinguish its operating modes. The green
LED indicates that power is ON. The red LED for the 800 or the 1900 band
is displayed only when that module is shutdown. When the unit is initializing,
all three LED lights blink 1 to 3 times.
3.1.2 To maintain constant power level, automatic level control (ALC) function is
used. When ALC detects excessive input power, auto shutdown process
begins separately for each Cellular and PCS module of the USHR- 0819SS.
3.2 Characteristics and Features
3.2.1 The unit is installed between the base station and the mobile phone and
allows better mobile phone coverage by amplifying weak base station signals.
3.2.2 This unit receives the downlink signal from the base station and processes
the signal using the ALC to pass a consistent signal (even if there is a
variation from the downlink signal) to the mobile phone.
3.2.3 This unit receives the uplink signal from the mobile phone and processes the
signal using the ALC to pass a consistent signal (even if there is a variation
from the uplink signal) to the base station.
3.2.4 Up on reboot from power outage or manual ON/OFF, the unit will initialize to
the last operating state before the power was off.
3.2.5 As the mobile phone is roaming out of the unit’ s coverage area, the call
hand- off should be smooth and there should be no interruption of the call in
progress.
