摘要:The present invention relates to a system (10) for the distribution of radiofrequency communications between a central control unit (11) and portable cordlessterminals (14), that cannot be reached directly by the control unit (11). The system (10)comprises a converting device (21, 31), situated between the control unit (11) and thecordless terminals (14), capable of converting the radio frequency communications tointermediate frequency communications, of transferring them on a cable (28, 38) and ofconverting them back to radio frequency communications to be able to exchange themwith the portable devices (14). The device (21, 31) is suitable, in particular, both fordistributing the so-called WWL (Wireless Local Loop) connections inside buildings, andalso for extending the area covered by the central control unit (11) in connections of thistype. The device (21, 31) also comprises an innovative band amplifier capable of avoidingthe so-called feedback effect.
