The authors examine conformally invariant wave equations for massless scalar, vector and tensor fields on 4-dimensional anti-de Sitter spacetime. This space is chosen since its symmetry group SO(3,2) possesses several remarkable properties, e.g. massless elementary systems can be defined in terms of its unitary irreducible representations. It is shown that only two values of the gauge-fixing parameter have a conformal origin.
