1. Introduction
Repeaters are used to fill out uncovered areas in cellular mobile systems, such as base
station fringe areas, road tunnels, business and industrial buildings, etc.
A repeater receives signals from a base station, amplifies and retransmits the signals
to mobile stations. Also it receives, amplifies and retransmits signals in the opposite
direction. Both directions are served simultaneously.
To be able to receive and transmit signals in both directions, the repeater is connected
to a donor antenna directed towards the base station and to a service antenna directed
towards the area to be covered.

Longent dual-band selective repeaters with 2 adjustable bandwidths have filters that
can be set to various bandwidths. This repeater type is suitable for the most carriers that need
2 band blocks support in 800 MHz cellular band.

The signal from the base station is received via the repeater donor (BS) antenna and is
then forwarded through a directional coupler (DC). The signal passes a duplex filter
(DPX), is amplified in a low noise amplifier (LNA), and enters the band selective
amplifier (BSA), which has two parallel bands.
The first mixer stage on the BSA amplifier, which is controlled by a synthesizer,
converts the received frequency down to the IF frequency. The signal is then filtered
by a SAW band pass filter and amplified before it is fed to the second mixer stage,
controlled by the same synthesizer as the previous one, for converting back to the
original frequency. The SAW filter can be adjustable for each BSA has adjustable
bandwidth.
A detector on the PA measures continuously the output level. The signal from this
detector is used by the automatic level control, ALC, to supervise and, if necessary,
reduce the output power to keep it under a setting level.
The output signal passes duplex filter (DPX) and fed to the repeater service (MS)
antenna.
The uplink signal path, i.e. from the mobile station through the repeater to the base
station, is identical to the downlink path the other way round. Only some levels and
component values differ.

4. Installation
A preferable site for the repeater is a tempered and ventilated place. If a repeater is
placed outdoor and can be exposed to direct sunshine, it is essential that the air can
circulate around the repeater with no obstacle.
Do not install or open a repeater at bad weather, such as intense rainfall, snowfall or
hail, storm or high wind, extremely low or high temperature and high humidity.
4.1. Mounting
1. Mount the provide bracket
Normally, the repeater is mounted on a wall. The mounting bracket is attached to a
wall using locking screws.
2. Hang the repeater
After attached the bracket, hang the repeater on the two upper supports and use one
M5 screw to fasten the repeater to the bracket.

4.2. Connection
1. Connect antennas
Connect the service antenna (MS) and donor antenna (BS) coaxial cables to the N
type female connectors marked with MS and BS.
2. Connect repeater to AC supply
Plug in the power connector on the bottom of the repeater.
3. Station ground
For the repeater supplied from mains, the mains outlet must be grounded. There is a
ground screw (M5) on the right side of the repeater.

5. Operation and Maintenance
5.1. WEB Interface
5.1.1. Introduction
Longent repeaters allow you to read and modify the current status via local WEB as well as
remote SNMP.
The main program features:
Supporting local WEB interface to show and modify the status value
Supporting Http 1.0
Supporting remote SNMP to show and modify the status value
Supporting SNMP versions 1, 2.
5.1.2. Hardware and Software Requirements
Your computer must meet the following requirements to be able to connect the repeaters via local
WEB interface:
Pentium III processor 600MHz or higher
RAM 64 MB minimum, 256 MB recommended
SVGA-compatible video card supporting the resolution of 800*600 or higher
Network adaptor
A cross cable to connect your computer and the repeater

5.1.3. Environment Configuration
The repeater uses the WEB interface to configuration. It used the static IP. Default IP is
192.168.15.15. So your computer must use the static IP too and the same subnet mask
(255.255.255.0). Your computer can use all the IP from 192.168.15.1 to 192.168.15.254 except the
repeater’s one (default is 192.168.15.15).
The method of configuration is following:
First, open the “start” menu. Choose the “Show all the connects” from the “Connect to”.
Ver. 0 14
In the “Network Connections” window, right click the “Local Area Connection” and choose the
“Properties” in the pop menu.
Ver. 0 15
In the “Local Area Connection Properties”, there is a “General” page. In this page, choose the
“Internet Protocol(TCP/IP)” in the “This connection uses the following items” list. Click the
“Properties” button.
Ver. 0 16
In this “Internet Protocol (TCP/IP) Properties” page, choose the “Use the following IP
address”, and sign the “IP address” like 192.168.15.14 and “Subnet mask” 255.255.255.0.
Others are empty.
Press the “OK” button, you’ll finish the configuration.
Now you can use a cross cable to connect your computer and the repeater. You can use IE to read
and notify the repeater information.
Exception: Access without the IP.
