1. SDR Repeater
1.1 Introduction
Four technologies in one body: SDR is an over-the-air repeater system that can incorporate up to four (4) technologies in one body. Current supported technologies are SMR800, SMR900, PCS, and BRS.
1.1.1 Highlights
• Supports up to 4 frequency bands simultaneously
oCovers the SMR800, SMR900, PCS, and BRS, LTE, Cellular, AWS bands
[SDR-S]SMR800- Covers 18 MHz
SMR900Covers 5 MHz
[SDR-P]PCS- Covers 65 MHz
3 independent RF PCS channels, each channel supports 1.25 to 18.75 MHz bandwidth
[SDR-B] BRSCovers 30 MHz
[SDR-700]LTE- Covers A+B:12MHz , C:11MHz
[SDR-C]Cellular- Covers 25MHz
[SDR-A] AWSCover 45MHz
•Composite Output Power of 24 or 30 dBm
•30 dB AGC Range @ 0.5 dB Step
•Adjustable AGC Output Power Level
•Adjustable ALC Level
•Band Selectable via Web-GUI
•Can Support up to 3 Non-Contiguous Bands on the PCS module
•Supports Network Management Monitoring System via SNMP
•Adjustable FA (3 channels)
•Digital filtering
•Incremental Automatic Shutdown/Resumption Time: SDR gradually increases the time span between automatic shutdown and resumption before it permanently shuts itself down
•Versatility and Usability: SDR gives total control to the user. Most of the control parameters, e.g., gain, output power, alarm threshold, etc. can be changed using the Web-GUI so that the user can adjust the system perfectly to the given RF environment
•Web-GUI connectivity via DHCP
•Supports DHCP; No 3rd party GUI software required
•Automated installation

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.

WARRANTY
Opening or tampering the SDR will void all warranties.
Lithium Battery: CAUTION. RISK OF EXPLOSION IF BATTERY IS REPLACED BY INCORRECT TYPE. DISPOSE OF USED BATTERIES ACCORDING TO INSTRUCTIONS.
Ethernet Instructions: This equipment is for indoor use only. All cabling should be limited to inside the building.
FCC Part 15 Class A
NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at their own expense.
CAUTION
Double Pole/Neutral Fusing.

3.2Switches and Ports
3.2.1Power 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.
