The repeater MR401B is a band selective repeater which bi-directionally amplifiessignals between mobile stations and a base station in a GSM1800 mobile telephonesystem It is employed wherever bad topological conditions cause poor field strengths Itcan provide highly selective amplification of the entire GSM1800 band or bandsegments thus enabling radio coverage in regions where satisfactory quality of communication is not available
MR401B modules can also be combined with MR341 or MR301B GSM900 repeater modules in order to create a combined GSM1800GSM900 repeater system Other modules operating in TACS ETACS and AMPS are available as well When differentmodules are combined a common antenna terminal and a common control interface isavailable
The repeater can be set locally or remotely A PCMCIA slot or RS232 interface for modem operation is available The design of the repeater comprises a large number of functions which the operator may monitor via terminal emulation programs or the MIKOMOMC software platform An easy to understand and fast to learn communicationlanguage supports the operator to query status reports from the repeater or to change
settings
bull Up to 30 MHz in GSM1800 band or smaller
segments
bull Built in test equipment
bull Easy and fast to install and to upgrade
bullbull Extremely small size and weight
Less than 19 litres
bullbull RS232 or PCMCIA data interface
bull Combination between GSM900 GSM1800
and ETACS possible
