User’s manual for channel selective repeater MRx41Manual updatex41.doc Id.-No. 148092 Page 10 24-Oct-00HEALTH AND SAFETY WARNINGSInstallerWarning: Any over the air radiated use of this product is intended to be usedwith either Roof Top (Building-mount) or Pole Mounted (Non-building-mount) fixed Antennas.Antenna installation must conform within the following guidelines tomeet FCC RF exposure limits, otherwise a environmental evaluationis required if:Broadband PCS (subpart E): Non-building-mounted antennas:height above ground level to lowest point of antenna < 10m Radio(Part 24) and total power of all channels > 2000 W ERP (3280 WEIRP).Building-mounted antennas: Total power of all channels > 2000 WERP (1640 W EIRP).For any clarification, please refer to FCC rules, 47 CFR ch. I, part 1.1307F Note: The electrical installation has to be performed in accordance withthe safety regulations of the local authorities. Due to safety reasonsthe electrical installation must be performed by qualified personnel.The cover of this unit should not be opened while power is applied.Subsequent installation, commissioning and maintenance activitiesthat require the unit to be powered with the cover open shall only becarried out by suitably qualified personnel.F Note: The grounding of the Unit has to be performed by all means. Agrounding bolt is provided at the cabinet in order to connect theearth bonding cable.F Note: The Unit is heavy-weight. Make sure that a suitable mountingsurface is used. Only adequate manpower is allowed to handle thesystem.F Note: ESD precautions have to be observed! Before maintenance work usethe available grounding system to connect ESD protectionmeasures.
User’s manual for channel selective repeater MRx41Manual updatex41.doc Id.-No. 148092 Page 13 24-Oct-001 INTRODUCTION1.1 Intended purposeCellular telephone systems transmit signals in two directions between base stations andmobile telephones within the signal coverage area.If weak signal transmissions occur within the coverage area because of indoorapplications, topological conditions or distance from the transmitter, a repeater is used toextend transmission range. In the downlink path the repeater picks up the signal from adonor 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 itscoverage area and re-transmits them to the corresponding base station.The over the air radiated use of this repeater is intended to be used with either Roof Topor Pole Mounted Antennas. To provide coverage in a indoor application one must mountthe antennas on or outside the building structure that is occupied. This must be done ina matter that conforms to the FCC RF exposure ( See health and Saftey section of thismanual).1.2 About the MRx41The repeater MRx41 is a channel selective amplifier, which bi-directionally amplifiessignals between multiple mobiles and a single base station in the GSM900, GSM1800,and PCS1900 mobile telephone system. It can provide highly selective amplification ofupto 8 channels, thus enabling radio coverage in regions where satisfactory quality ofcommunication is disabled. The basic unit is capable of 2 channels.The MRx41 can be set-up locally or remotely. A PCMCIA slot for modem operation is anavailable option. The repeater has a large number of functions that can be monitoredand changed by the operators via a terminal emulation program or the MIKOM OMCsoftware platform. An easy to understand and simple to learn communication languageis available to help the operator query status reports from the repeater or to changesettingsF Note: It is not possible to combine PCS 1900 MRx41 units / modules withother MRx41 units / modules.
