Abstract :
Indoor traffic is expected to be key in 3G networks. Nevertheless, the implications of indoor traffic in a 3G WCDMA-based network may be significantly different from those already well known in 2G TDMA-based networks. This paper reveals, by means of a simple analytical model that uplink is much more sensitive than downlink in WCDMA in terms of capacity degradation due to increased indoor traffic levels. Additionally, by means of system level simulation the capacity degradation in different conditions is assessed in both links.
