Abstract

For a two operator WCDMA indoor scenario, we observe dead zones of poor coverage on the downlink corresponding to areas near a cell boundary where a competitor base station is located. Both the uplink and downlink capacity are reduced, but the effect is quite small in percentage terms. However, there is an influence on the cell coverage, i.e. the interference restricts where traffic can be supported. The primary reason for the inter-operator interference is shown to be the adjacent channel leakage and the adjacent channel selectivity associated with the mobile terminal
