Abstract The local and premises wireless networks have been expanding into
many areas. The core network access point or basic station infrastructure can be
made on wireless systems, on fixed cable systems with metallic twisted pairs,
and, prospectively with optic fibers. The VDSL2 line systems with VDMT
modulation and line bounding will be used for a data speed of hundreds Mb/s
and distance between active nodes can be measured in hundreds meters. A
suggestion of active access network and simulation of data bit rate is presented.

Keywords: Core network, Active access network, VDSL2, VDMT modulation

1 Introduction

The backbone or core network access point or basic station infi°astructure can be made
on wireless systems, or on fixed cable systems with metallic twisted pairs and
prospectively with optic fibers. Optical fibers are gradually replacing the metallic
lines, and data bit rates have increased fi*om tens Mb/s to hundreds Mb/s or Gb/s in
LANs and in the access network (first miles of digital subscriber lines). However, the
information capacity of metallic lines can be increased if the systems use a VDSL2
[8], physical layer with vectored DMT modulation and line bounding concept. The
methods for partial crosstalk cancellation are discussed and simulation results are
presented for the middle-range used for connection of access points. The data bit rates
100 Mb/s and 1 Gb/s are currently used for interfaces and connection to backbone

2 Conception of core network

If it is necessary to cover some area by high-speed wireless technology [6], the
connection of access points to the central point of the network gateway has to be set.
For connection of the access points sufficient throughput is necessary and hence the
reason for building an efficient core network arises.

Wu-eless point-to-point or fixed point-to-multipoint connections are used for
attachment of access points. This solution is not suitable under all circumstances.
There can be problems with low throughput, interferences and insufficient bandwidth.

For extreme throughput of the core network a fiber optic FTTB (Fiber to the
Building), or FTTN (Fiber to the Node) FTTN conception can be used (Node is a
wireless access point AP - see fig.l). Here the length of the cables is restricted for
common low-coast interfaces to 10 - 20 km, which is more than satisfactory and also
the transmission speed IGb/s, eventually 10 Gb/s, offers a large reserve.
