intelligent design and versatility, the Duo-i6525 is the ideal choice for wireless
coverage problems indoors. Duo-i6525 can be used as a stand-alone repeater with
passive antennas connected to it or it can also be used as a feeder repeater to a
DAS (Distributed Antenna System).
1.1.1 Highlights
• Dual Band Repeater (800 & 900 MHz)
• 25 dBm Composite Output Power
• 65 dB gain
• 25 dB AGC Range @ 0.5 dB Step
• Digital Filtering
• Excellent Out-of-Band Rejection Characteristics with Sharp Roll-Offs
@ 65 dBc
• Re-Banding Capability via Digital Filtering
• Band Adjustable Option @ 200 KHz Step
• Web GUI Software via DHCP
• Oscillation Detection Scheme

1.2 Warnings and Hazards
WARNING! ELECTRIC SHOCK
Opening the Duo-i6525 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
exposure to RF electromagnetic fields.
www.fcc.gov/oet/rfsafety to learn more about the effects of
WARNING! DAMAGE TO
Operating the Duo-i6525 with antennas in very close proximity facing each
other could lead to severe damage to the repeater.
RF EXPOSURE & ANTENNA PLACEMENT
Actual separation distance is determined upon gain of antenna used.
Please maintain a minimum safe distance of at least 20 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 Duo-i6525 will void all warranties.

FCC STATEMENT
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 own expense.

User Manual V1.2
2.2 Operation Modes
2.2.1 Local Web GUI
Simply connect one end of the ethernet cable on the repeater monitor port and
the other end on the PC’s LAN port. After doing so, launch the Microsoft
Internet Browser (Internet Explorer) and the Local Web GUI will be launched
through typing the IP address (http://192.168.63.1/home.asp)
2.2.2 Remote NMS (Modem Option)
A CDMA wireless modem can be integrated within a Duo-i6525 repeater.
With this wireless modem, the user can remotely log into the repeater for
monitoring purposes.
2.3 Components
2.3.1 Power Supply
It provides DC power to each module within the repeater.
2.3.2 Controller
It is responsible for monitoring the status of each module and controls its
parameters. If a CDMA wireless modem is integrated within the repeater, it
also handles the remote “Command & Control” feature as well.
2.3.3 Down Converter Module
The downlink RF signal entered through the cavity filter is converted to IF
frequency, which is later converted back to RF frequency again through digital
filtering. The downlink HPA (high power amplifier) is integrated with th e
Down Converter Module.
2.3.4 Up Converter Module
The uplink RF signal entered through the cavity filter is converted to IF
frequency, which is later converted back to RF frequency again through digital
filtering. The uplink HPA (high power amplifier) is integrated with the Up
Converter Module.
