User’s manual for Remot e Unit MOR801B Power
1 Introduction
1.1 Intended purpose
Cellular telephone systems transmit signals in two directions between base stations and mobile telephones within the signal coverage ar ea.
If weak signal transmissions occur within the coverage area because of indoor applications, topological conditions or distance from the transmitter, a Repeater is used to extend transmission range. In the downlink path the Repeater picks up the signal from a donor antenna of an existing cell, amplifies and re-transmits it into the desired dark spot. In the uplink direction the Repeater receives signals from mobile stations present in its coverage area and re-transmits them to the corresponding base station.
1.2 About the MOR801B POWER
MIKOM’s MOR801B Power Remote is available as a band or channel selective optical repeater for Analog, CDMA, and TDMA technology.
The MOR801B Power Remote repeater bi-directionally amplifies signals between multiple mobiles and a single base station in the AMPS800 frequency band using optical fibres for interconn ection to a Master Unit . It is employed ma inly in tunnels, canyons, an d other areas , where physical structures cause weak field strengths. It can provide highly selective amplification of band segments or channels in the AMPS800 band.
The MOR801B Power Remote can be combined with other repeaters in order to create a multi-band optic al repeater system. Modules opera ting in PCS1900, GSM18 00, GSM900, or iDEN bands are available. When different modules are combined a common antenna and control interface is available.
The MR801 Power Remote can be set-up locally at the Master Unit through the optical fibre or remotely at the OMC. A PCMCIA slot for modem operation is an available option at the Master Unit. The repeater has a large number of functions that can be monitored and changed by the opera tors via a terminal emula tion program or the MIKOM OMC software platform. An easy to understand and simple to learn communication language is available to help the operator query status reports from the repeater or to change settings.

User’s manual for Remot e Unit MOR801B Power
2.1 General
The Repeater consists of two amplifier chains. The signals to and from the mobiles are combined to an antenna by a frequency separation unit, denominated in the following as Duplexer. The optical signals to and from the Master Unit are converted by the Optical Transceiver.
In the Downlink direction the optical signals from the Master Unit are converted into RF­signals by the Transceiver (see chapter 2.7). They pass the 4-way-Splitter (see chapter2.9), which provides the RF-signal for the RF modules. After the RF module (see chapter 2.2) they are comb ined by the Act ive C ombin er (see c hap ter 2. 6) and a fter wards ampli fied by t he Feed Forward Amplifier (see chapter 2.12), which provides the required output power. Finally the signals are fed to the antenna by the Duplexer (see chapter 2.5).
In the Uplink direction the signals from the mobiles are seperated by the Duplexer, get to a Pre-Amplifier and afterwards to an RF module. The signals are combined by the Active Combiner then, get converted into optical signals by the Transceiver (see chapter 2.7) and are finally transmitted to the Maste r Uni t.
In the final amplifier of the Downlink a power detection measures the output power and controls the gain. In the Uplink the gain is controlled by the Active Combiner to protect the Optical Transceiver. This power detection is called Automatic Level Control (ALC) (see chapter 3.3).
2.2 RF modules
The task of the RF modules is to amplify the receive signals and to convert them into an intermediate fr equency. Th e signals, then, proceed a filter stage comprising of highly se lectiv e filters, a nd run th rough a digi tal c ontrollab le at tenuat or. The a ttenua tion can be set in step s of 2 dB, locally or remotely. By using the same synthesizer frequency, that was used to convert the signals down to intermediate frequency, the intermediate frequency is mixed up to the original frequency.
The synthesizer is controlled via an I²C-Bus. In case of a breakdown in mains, gain and frequency data are non-volatile stored in an EEPROM on board.
See figure 2-2 Top view of an RF module for an exemplary channel or band module.

2.3 Mother board
The function of the mother board is the communication between the RF modules and the control module via the I²C-Bus.
In the three and four channel configuration of the Repeater there is a mother board on the left­and on the right-hand side, whereas in the one and two channel configuration there is only one mother board implemented on the right-hand side of the Repeater.
Mother boards are located underneath the RF modules.

User’s manual for Remot e Unit MOR801B Power
2.4 Control module SM 2009
The control module SM 2009 is a DOS compatible micro computer. The whole communication between the operator and the Repeater can be done via the control module. By using the RS232 interface the Repeater can be controlled locally by using a VT100 terminal, or a PC emulating the VT100 terminal.
Frequency and gain, power down of RF stages and ALC can be controlled and status messages can be received remotely via the Master Unit.
The data transfer bet ween the control modu le SM 2009 and the m other board is rea lized by the I²C-Bus system.
The I²C-Bus concept was developed by Philips for the serial connection of integrated circuits within one device. Two wires, SDA - serial data and SCL - serial clock, carry data between the devices connected to the bus. Each device is recognized by a unique address and can operate either as transmitter or receiver.
All MOR801B Power configuration parameters are stored in an EEPROM on the control module if a power supply failure occurs.
