UMTS Femtocell Performance in Massive Deployments: Capacity and GoS Implications

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.
