"Universal broadband telecommunications hu00ecbridas using small radio cells interconnected by links free space optics.These are several communication terminals connected via a broadband radio to a communications network in any one of three sizes typically hierarchical cells increased.Typically, a simple construction of a city region.Almost all the telecommunications sweat, however, in the "picocu00e9lulas 1" of the lowest level and the base stations 11 "low cost that have, typically,A radio transceiver (111), four optical transceivers (112), a key ATM (113) and an ATM controller (114).Each base station (11) "place is interconnected to a" key (12), which is connecting to a main source of wire line communications world / fibre (4),In a mesh network of multiple jumps (100) via optical links directional broadband free of SACE highly focused short (10).The wireless broadband access of free space, the need for new cable broadband access in the "last mile" to subscribers / users is eliminated.The service of the subscriber is in the order of 20 MB / rate at the peak and 10 Mb / s average rate.
