The base station router (BSR) femto node-a Universal Mobile
Telecommunications System (UMTS) Node B for domestic use that admits a
limited number of simultaneous communications-is gaining interest among
mobile operators worldwide. Its main advantages are that it connects
with the mobile core network through the land digital subscriber line
(DSL) at the user's home, relieving the macro network from the indoor
traffic that uses a substantial part of the mobile network resources.
This paper explains the network deployment and dimensioning rules used
in the massive deployment of this type of node. The proposed models are
verified through node performance network simulations in different types
of residential configurations, taking into account challenging aspects
such as the neighboring effect, macro-femto cell interaction, arbitrary
node localization, and service (voice, data, and video) mix. The model
is applied to 2 GHz and 850 MHz bands. (C) 2009 Alcatel-Lucent.
