Capacity of the swedish copper access network
Author
Summary, in English
This paper aspires to indicate how much broadband communication the Swedish copper access network can offer
when developed to its full potential. We look at
a number of different infrastructure deployment scenarios
and calculate the Shannon capacity of the copper
loops using different deployment-dependent loop-length
distributions with different deployment-dependent and
technology-dependent noise models. We investigate both
deployment from the central-office and from the cabinet.
We consider non-cooperative scenarios, where the deployment is carried out system by system following only the mandatory standardised rules and every line is operated autonomously without cooperation of transceivers. We also investigate scenarios with mechanisms for better exploitation of the access plant through dynamic spectral management, multiple-input multiple-output techniques, and common-mode aided interference suppression. The choice of elementary parameters, like transmit power and background noise, is based on today’s digital subscriber line (DSL) standards. Statistical models are used for the main parameters of the network topology. Note that we are not calculating a capacity in an information theoretic sense, but rather a data rate under given constraints.
