A data connection device and method in a transport network in a cellular mobile system between a base station controller (BSC) and base station sites (12, 13, 14) which radiate information to and from mobile terminals connected to a radio base system (RBS) in an environment demanding narrow cellular positions. The transport network comprises at distributed cross connect means (DXX) having a network management system (11) for managing the transfer. The distributed cross connect means (DXX) has at least one wireless radiation node intended for a wireless transparent connection to be provided between the wireless radiation node (RN) and a wireless radiation terminal (RT). The wireless radiation node means (RN) for several base station sites (RBS) comprises a wireless radiation network (RNC) controlled by the network management system (11). A central cross connect node (C-DXX) in the wireless radiation node (RN) cooperates with the wireless radiation network means (RNC) and central wireless radiation station means (CRS 16; CRS') functioning as a distributed group switch having a point-to-multipoint system. The wireless radiation terminal (RT) is provided for each base station site (RBS) to be wirelessly connected to the wireless radiation node (RN). |
