  The GaLactic and Extragalactic All-sky MWA survey (GLEAM) is a new relatively
low resolution, contiguous 72-231 MHz survey of the entire sky south of
declination +25 deg. In this paper, we outline one approach to determine the
relative contribution of system noise, classical confusion and sidelobe
confusion in GLEAM images. An understanding of the noise and confusion
properties of GLEAM is essential if we are to fully exploit GLEAM data and
improve the design of future low-frequency surveys. Our early results indicate
that sidelobe confusion dominates over the entire frequency range, implying
that enhancements in data processing have the potential to further reduce the
noise.
