2. Warnings and Hazards
WARNING! ELECTRIC SHOCK
Opening the SDR could result in electric shock and may cause severe injury.
WARNING! EXPOSURE TO RF
Working with the repeater while in operation, may expose the technician to RF electromagnetic fields that
exceed FCC rules for human exposure. Visit the FCC website at www.fcc.gov/oet/rfsafety to learn more
about the effects of exposure to RF electromagnetic fields.
WARNING! DAMAGE TO REPEATER
Operating the SDR with antennas in very close proximity facing each other could lead to severe
damage to the repeater.
RF EXPOSURE & ANTENNA PLACEMENT Guidelines
Actual separation distance is determined upon gain of antenna used.
Please maintain a minimum safe distance of at least 60 cm while operating near the donor and the server antennas. Also, the donor
antenna needs to be mounted outdoors on a permanent structure.

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.

User Manual V0.4
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 SDRCHC 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.

figure below.

Page | 16
SDR Repeater
User Manual V0.4
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.
Page | 17
SDR Repeater
User Manual V0.4
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.

4. SDR Web-GUI Setup
The Web-GUI allows the user to communicate with the repeater either locally or remotely. To connect to the repeater
locally, you will need a laptop with an Ethernet port and a RJ-45 crossover cable. To connect to the repeater remotely,
you will need to have an active internet connection and the repeater must have either an internal modem or an Omnibox
(ADRF Modem Box) connected to the repeater.

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
VSWR Alarm ON: Allow the user to enable/disable the VSWR alarm check

Start Frequency:
If a start frequency is specifed, then this will be the beginning frequency of the band selection. Adding the
bandwidth value that is selected from the Bandwidth column will give you the end frequency of your band
selection.
Center Frequency:
Once a center frequncy is specified and a bandwidth is selected, the system will split the bandwidth value in
half and then add this to the center frequency to obtain your end frequency and also subtract this value to
obtain your start frequency.
Stop Frequency:
If a stop frequency is specified, then this will be the ending frequency of the band selection. Subtracting the
bandwidth value that is selected from the Bandwidth column will give you the start frequency of your band
selection.

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.

MPE Information
Warning: Exposure to Radio Frequency Radiation The radiated output power
of this device is far below the FCC radio frequency exposure limits.
Nevertheless, the device should be used in such a manner that the potential
for human contact during normal operation is minimized. In order to avoid
the possibility of exceeding the FCC radio frequency exposure limits, human
proximity to the antenna should not be less than 60cm during normal
operation. The gain of the antenna is 3 dBi. The antenna(s) used for this
transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
