3CC12424AAAA TQ BJA 01 Issue 01 - April 2001 - Draft 04 17/302302 Equipment overview2.1 Overview of the A7390 systemThe Alcatel 7390 is a multi-service broadband wireless local loop system designed to provide telecomservices to small and medium-sized enterprises.Broad band WLL (Wireless Local Loop) system, Alcatel 7390 allows operators to offer rapid provision -to a large number of client sites - of a comprehensive range of telephone and data transmissionservices.For cellular phone network operators, Alcatel 7390 offers the possibility of linking base stations tobase station controllers. This makes Alcatel 7390 an economical transmission solution, for theimplementation or extension of high traffic density areas coverage.For mixed network operators (fixed and mobile), Alcatel 7390 enables to connect, with the samesystem, fixed professional end user as well as base stations of cellular telephony.Figure 1 – A7390 System - Local point - multipoint service distribution -SMEIndependant professionIndependant professionCompagny DCompagny ACompagny BCompagny C
