User Manual V0.4

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

o Covers the SMR800, SMR900, PCS, and BRS, LTE, Cellular, AWS bands

 [SDR-S]SMR800- Covers 18 MHz

SMR900- Covers 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] BRS- Covers 30 MHz
 [SDR-700]LTE- Covers A+B:12MHz , C:11MHz
 [SDR-C]Cellular- Covers 25MHz
 [SDR-A] AWS- Cover 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 3

• Automated installation

2. Warnings and Hazards

WARNING! ELECTRIC SHOCK

Opening the SDR could result in electric shock and may cause severe injury.

W ARNING! 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
about the effects of exposure to RF electromagnetic fields.

to learn more

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.

Double Pole/Neutral Fusing.

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.

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.

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 [e-mail]
