3.2 Switches and Ports
3.2.1 Power Switch
The AC Power on/off switch is located at the back of each individual module. Each module must be powered on
separated. The switch should be powered on after the repeater has been installed properly.
Figure 2: SDR Repeater Power Switch View
3.2.2 Back Up Battery Switch & Battery Port
Figure 3: Battery Backup Port
The SDR module can be connected to an ADRF-BBU (ADRF Battery Backup) to provide power during a power
failure. If an ADRF-BBU is utilized, connect the ADRF-BBU to the SDR via the external battery port as shown in
Figure 4.
(WARNING: The circuit switch on the ADRF-BBU must be set to OFF before connecting the ADRF-BBU
to the SDR to prevent damage to the repeater or the ADRF-BBU and personal injury.)
Note: Please contact ADRF Technical Support for assistance if you are unfamiliar with the installation
procedure of our battery box.

3.2.3 Ethernet Port and Host/Remote Switch
Ethernet Port
The Ethernet port can be used to communicate directly with the SDR using a RJ-45 crossover cable or can
also be used to connect the SDR to an external modem box.
Host/Remote Switch
The Host/Remote Switch allows the user to switch the default Repeater IP, Subnet Mask, and Gateway of the
repeater to an alternative setup. These settings can be adjusting by logging into the repeater in HOST mode
and configuring the settings under the Modem Box Setting section on the Install Page (section 4.4). Once the
settings are set, flipping the switch to the REMOTE position will reboot the repeater with the new alternate
settings. Please note that when the repeater is set to the REMOTE position, DHCP is disabled and the
repeater will not automatically assign an IP address to any device that connects directly to the repeater.
Figure 4: Ethernet Port and Host/Remote Switch
3.2.4 RF Ports
Module RF Ports
Donor and server antennas can be connected directly to the modules or the optional SDR-CHC (channel
combiner) can be used to split or combine signals.
Figure 5: RFU RF port
Optional SDR-CHC
An optional channel combiner can be mounted directly above the SDR. The donor portion of the SDR-CHC
can be used to split up a combine donor signal into PCS, BRS, and SMR. The server portion of the SDR-
CHC can be used to combine the server signals (PCS, BRS, 2.4 GHz WIFI, and SMR) into the Server Sum
port. Please contact sales@adrftech.com if you are interested in purchasing the SDR-CHC.

User Manual V0.4
Page | 17
3.5.4 Antenna Separation/Isolation
Separation between the antennas is necessary to prevent oscillation. Oscillation occurs when the signal entering the
system continually reenters, due to the lack of separation between the donor and server antennas. In other words, the
signal is being fed back into the system. This creates a constant amplification of the same signal. As a result, the
noise level rises above the signal level.
Figure 9: RF Repeater Oscillation
To prevent feedback, the donor and server antennas must be separated by an appropriate distance to provide
sufficient isolation. Isolation is attained by separating antennas a sufficient distance so that the output of one
antenna does not reach the input of the other. This distance is dependent on the gain of the repeater.
A sufficient isolation value is 13 ~ 15 dB greater than the maximum gain of the repeater. For example, if the gain of
the repeater is 50 dB, then an isolation of 63 ~ 65 dB or greater is required. In the same manner, because the SDR
has a maximum gain of 90 dB in case of SDR-24, it requires an isolation of at least 103 ~ 105 dB.

3.5.5 Line of Sight
The donor antenna which points towards the base station typically has a narrow beam antenna pattern. As a result,
a slight deviation away from the direction of the BTS can lead to less than optimum results. In addition, obstacles
between the repeater and the BTS may impair the repeater from obtaining any BTS signal. As a result, the repeater
cannot transmit signal to the coverage area. Therefore, a direct line of sight to the BTS for the donor antenna is vital
to the function of a repeater. For the same reason, placing the server antenna in direct line of sight of the coverage
area is also necessary.

o DL Output ALC Offset: The amount of gain that the system has to work with before raising the gains
to match the DL Output ALC Level specified
o DL /UL Gain Balance ON: When enabled, the system will keep the delta value between the Downlink
and Uplink gain levels
4.3.2.6 Alarm Setting
o Downlink Signal Low: Allows the user to specify the how weak the signal can be before triggering a
“Downlink Signal Low” soft-fail alarm
o Downlink Signal Not Detected: Allows the user to specify the how weak the signal can be before
triggering a “Downlink Signal Not Detected” soft-fail alarm
o Downlink RF Power: Allows the user to set a maximum deviation value for the downlink RF power
For example, if the input signal is -50 dBm and the gain is set to 60 dB, the expected output
power should be 10 dBm. If the Downlink RF Power alarm value is set to 6dB, then if the
output power is below 4 dBm, then this will trigger a soft-fail alarm
o VSWR Alarm ON: Allow the user to enable/disable the VSWR alarm check

Appendix B: Shutdown Retry Logic
The function of the built-in shutdown routine is to protect the repeater from any further damage from a hard-fail that the
system may be experiencing.
Within 5 seconds of a hard-fail alarm being detected, the repeater will start the shutdown routine. The repeater will shut
down by powering of the HPAs (high-powered amplifiers) for 30 seconds.
After 30 seconds have elapsed, the repeater will power on the HPAs and check to see if the hard-fail alarm still exist. If
the hard-fail alarm still exists, then the repeater will shut down for 1 minute (double the time of the previous shutdown
time).
After 1 minute has elapsed, the repeater will power on the HPAs and check to see if the hard-fail alarm still exist. If the
hard-fail alarm still exists, then the repeater will shut down for 2 minutes (double the time of the previous shutdown time).
The shutdown routine will repeat itself a total of 10 times. If the hard-fail alarm still exists after the 10th retry, then the
repeater will turn off its HPAs permanently until a reset is performed or factory set is executed.
