The paper describes a new scenario for how to transform the existing telephone access network into a real broadband network.
The objective is to introduce a low-cost network evolution scenario, which makes maximal use of the huge investments connected
to this kind of networks. The existing network is sub-divided into a small cell network, each covering an area with an approximate
radius of 1 kilometre. Inverse multiplexing of xDSL systems is used to aggregate bandwidths in the range of 100 to 1000 Mb/s
between nodes in the network. VDSL modems able to carry about 25–50 Mb/s, are used on the last section from the node to the
customer premises. These modems provide all households within each geographical cell with real broadband access to a large
common bandwidth.
