PCT No. PCT/EP95/04509 Sec. 371 Date May 14, 1997 Sec. 102(e) Date May 14, 1997 PCT Filed Nov. 14, 1995 PCT Pub. No. WO96/15642 PCT Pub. Date May 23, 1996A radio access unit for establishing radio link connections with a plurality of geographically spread remote telecommunication units. The radio access unit comprises radio access modules and antenna means (46), operatively connected to provide a plurality of common radio communication channels in directionally separated transmission sectors (66-71). The radio access modules are arranged for adaptively selecting a free communication channel amongst the plurality of common radio channels in a transmission sector (66-71); i.e. Dynamic Channel Allocation (DCA). The selected channel is individual to a radio link connection in such transmission sector (66-71). The radio access unit can be used in Radio in the Local Loop (RLL) applications and cellular overlay multicell mobile communication networks.
