2. Duo-i6515/6525/8030NM Overview

2.1 Operation Modes

2.1.1. Local Web GUI

Host Mode

This mode should be selected only if a Duo-i6515/6525/8030NM is used
alone without being connected to any other device functioning as a host.

Simply connect one end of the ethernet cabl e o n 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

)

󰼿

2.1.2. Remote Web GUI

Remote Mode

This mode should be selected if an external modem box (MBOX-DET1) is
being installed along with the Duo-i6515/6525/8030NM for monitoring
purposes. In this case, the Duo-i6515/6525/8030NM works as a remote unit
sending its information to the collocated external modem box.

Note: ADRF’s Web GUI has not been developed for Microsoft Internet Explorer and other
web browsers (e.g. Netscape, FireFox, Mozilla, etc.) may not be compatible. ADRF’s Web
GUI has not been tested with Microsoft Internet Explorer versions higher than 6.0.

2.2 Switches & Indicators

2.2.1. LEDs

The Duo-i6515/6525/8030NM has three LEDs on the front panel of the
repeater as show below in Figure 4.

Figure 4 – Duo-i6515/6525/8030NM Repeater LED View

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 vi a the local web GUI.
In the event of a soft fail alarm, the repeater will still function, but the alarm
needs to be addressed prom ptly.

HARD FAIL

If the LED is lit RED, it indicates that there is a hard fail alarm in the system.
The detailed alarm information ca n 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.

2.2.2. AC Power Switch & DC Power Port for External Modem Box

The AC Power on/off switch is located on the bottom of repeater (Figure 5).
The switch should be powered on after the repeater has been installed properly.

The DC Power Port can be used to provide power to the optional External
Modem Box (Figure 5).

Figure 5–AC Power Switch & DC Power Port

2.2.3. Mode Selection Switch and Ethernet Port

The Ethernet port and the Mode Selection Switch for DHCP are located on
bottom of the repeater as shown below in Figure 6. The mode selection
switch has two modes: Host Mode & Rem ote Mo de.

2.3 Installation

2.3.1 Tools

No special tools or equipment are needed to install the Duo­i6515/6525/8030NM.

2.3.2 Procedure

Four (for Duo-i6515/6525NM) or six (for Duo-i8030NM) mounting holes are
provided on the wall-mounting bracket to attach it to the wall. The wall
bracket must be securely attached to suff iciently carry the weigh t of the Duo­i6515/6525/8030NM, which is bolted to the wall bracket through four or six
aligned mounting holes.

The following steps should be followed while mounting the repeate r:

Installation Procedure (Wall Mount)

① Take the Duo-i6515/6525/8030NM out of the box
② Using the four or six anchor bolts, mount the bracket on the wall
③ Make sure the bracket is securely mounted
④ 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.

⑤ Make sure the Duo-i6515/6525/8030NM is securely placed onto the wall

bracket

⑥ Fasten the 8 bracket screws back pr operly
⑦ Inspect that everything is secure

* Rack Mount option is also available. Please contact ADRF for additional
information.

User Manual V1.6

2.3.4 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 oth er wo rds, th e
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.

Server

Figure 9 - RF Repeater Oscillation

To prevent feedback, the donor and serv er 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, since the Duo-i8030NM has a maximu m gain of
80 dB, it requires an isolation of at least 93 ~ 95 dB.

Duo-i6515/6525/8030NM

User Manual V1.6

2.3.5 Line of Sight

The donor antenna which points towards the base station typically has a
narrow beam antenna pattern. As a result, a slight devi ation 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.

Power Supply

It provides DC power to each module within the repeater.

Controller

It is responsible for monitoring the status of each module and controls its
parameters. Also it interfaces with PC through Ethernet port.

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 thr ou g h dig ita l
filtering.

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 thr ou g h dig ita l
filtering.

Quad-Plexer

It consists of four BPFs (band-pas s filters) each of the four RF signal paths:
SMR 800 (Tx & Rx) and SMR 900 (Tx & Rx)

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.
