This study investigates different correlation based models useful for evaluation of outage capacity (OC) of mobile multiple‐input and multiple‐output (MIMO) handsets. The work is based on a large measurement campaign in a micro‐cellular setup involving two dual‐band base stations (BSs), 10 different handsets in an indoor environment for different use cases and test users. Several models are evaluated statistically, comparing the OC values estimated from the model and measurement data, respectively, for about 2700 measurement routes. The models are based on either estimates of the full correlation matrices or simplifications. Among other results, it is shown that the OC can be predicted accurately (median error typically within 2.6%) with a model assuming knowledge only of the Tx‐correlation coefficient and the mean power gain.
