  This paper presents the results of the first multi- antenna propagation
measurement campaign to be conducted at an operating petroleum refining
facility. The measurement equipment transmits pseudo-random noise test signals
from two antennas at a 2.47 GHz carrier with a signal bandwidth of
approximately 25 MHz. The measurement data is analyzed to extract path loss
exponent, shadowing distribution, fading distribution, coherence bandwidth and
antenna correlation. The results reveal an environment where large scale
attenuation is relatively mild, fading is severe and good performance is
expected from both antenna and frequency diversity.
