The effective capacity of communication systems over generalised κ – μ shadowed fading channels is investigated. A novel and analytical expression for the exact effective capacity is derived in terms of the extended generalised bivariate Meijer's‐ G function. To intuitively reveal the impact of the system and channel parameters on the effective capacity, closed‐form expressions are derived for the effective capacity in the asymptotically high signal‐to‐noise ratio regime. The results demonstrate that the effective capacity is a monotonically increasing function of channel fading parameters κ and μ as well as the shadowing parameter m , while it decays to zero when the delay constraint θ → ∞.
