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.
RF EXPOSURE & ANTENNA PLACEMENT
Opening or tampering the Duo-i6525 will void all warranties.
WARRANTY
Operating the Duo-i6525 with antennas in very close proximity facing each
other could lead to severe damage to the repeater.
WARNING! DAMAGE TO

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 the
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.

2.3.5 Quad-Plexer
It consists of four BPFs (band-pass filters) each of the four RF signal paths:
SMR 800 (Tx & Rx) and SMR 900 (Tx & Rx)
2.3.6 Digital Filter
It is composed of A/D (analog to digital) and D/A (digital to analog) converters.
It also has a FPGA (field programmable gate array) which has the capability
for superior out-of- band rejection and re-banding.

2.4 Switches & Indicators
2.4.1 LEDs
Duo-i6525 has three LEDs on the top panel of the repeater as show below in
Figure 4.
POWER
If the LED is lit GREEN, it indicates that there is AC power to the repeater.
SOFT FAIL
If the LED is lit YELLOW, it indicates that there is a soft fail alarm in the
system. The detailed alarm information can be viewed via the local web GUI.
In the event of a soft fail alarm, the repeater will still function, but the alarm
needs to be addressed promptly.
HARD FAIL
If the LED is lit RED, it indicates that there is a hard fail alarm in the system.
The detailed alarm information can be viewed via the local web GUI. In the
event of a hard fail alarm, the repeater will not function and immediate
attention is required.

2.4.2 Power Switch
The AC Power on/off switch is located on the bottom of repeater. The switch
should be powered on after the repeater has been installed properly.
2.4.3 Mode Selection Switch
The Ethernet port and the mode selection switch for DHCP are located on
bottom of the repeater as shown below in Figure 5. The mode selection switch
has two modes: Host Mode & Remote Mode.

Figure 8 – DHCP & Mode Selection Switch View
Duo-i6525 RF Repeater
User Manual V1.2
Advanced RF Technologies, Inc. Proprietary Document Page 14 of 32
Host Mode
This mode should be selected only if a Duo-i6525 is used alone without being
connected to a collocated Sprint Nextel CDMA repeater functioning as a host.
Remote Mode
This mode should be selected if a Sprint Nextel CDMA repeater is being
installed along with aDuo-i6525 and the ethernet port is being used for
communicating with the CDMA repeater. In this case, a Duo-i6525 works as a
remote sending its information to the collocated Host CDMA repeater.
2.5 Installation
2.5.1 Tools
No special tools or equipments are needed in installing the Duo-i6525.
2.5.2 Procedure
Four mounting holes are provided on the wall-mounting bracket to attach it to
the wall. The wall bracket must be securely attached to sufficiently carry the
weight of the Duo-i6525, which is bolted to the wall bracket through four
aligned mounting holes.
The following steps should be followed while mounting the repeater:
Installation Procedure
① Take the Duo-i6525 out of the box
② Detach the mounting bracket from the Duo-i6525 by unscrewing the 8
screws on the bracket. (4 on each side)
③ Using the four anchor bolts, mount the bracket on the wall
④ Make sure the bracket is securely mounted
⑤ Slightly tilt the repeater and mount the repeater onto the wall as shown in
the picture. Hook the upper 2 guard screws first and then slide/push in the
lower 2 guard screws into the place.
⑥ Make sure the Duo-i6525 is securely placed onto the wall bracket
⑦ Fasten the 8 bracket screws back properly
⑧ Inspect everything is secure

2.5.3 Grounding
The Duo-i6525 has locks on the side of the enclosure preventing from the door
opening. In addition, a ground cable is also included in the box and should be
connected to repeater.
2.5.4 Antenna Separation/Isolation
Separation between 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 10 – Ground Cable Connection
Duo-i6525 RF Repeater
User Manual V1.2
Advanced RF Technologies, Inc. Proprietary Document Page 17 of 32
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 Duo-i6525 has a maximum gain of 65 dB, it requires an
isolation of at least 78 ~ 80 dB.

Duo-i6525 RF Repeater
User Manual V1.2
Advanced RF Technologies, Inc. Proprietary Document Page 18 of 32
2.5.5 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.
