With new technologies such as machine-to-machine communications there is a growing need to test large-formfactor devices in reverberation chambers. The performance of the reverberation chamber can be affected by the physical characteristics of these devices. In this paper it is discussed how the spatial uniformity is affected by a large object. A distinction is made between reflecting and absorbing objects. A link is shown between the spatial uniformity and the K-factor. It is shown that large metallic objects cause minimal degradation in the spatial uniformity. Absorbing objects can cause substantial
degradation in the spatial uniformity, motivating the need for testing guidelines for these objects.
