  Real-time distributed control is a promising application of 5G in which
communication links should satisfy certain reliability guarantees. In this
letter, we derive closed-form maximum average rate when a device (e.g.
industrial machine) downloads a sequence of n operational commands through
cellular connection, while guaranteeing a certain signal-to-interference ratio
(SIR) coverage for all n messages. The result is based on novel closed-form
n-successive SIR coverage bounds. The proposed bounds provide simple
approximations that are increasingly accurate in the high reliability region.
