  This letter offers the first characterisation of the stability for
full-duplex large size networks. Through stochastic geometry tools, key
performance metrics like delay and maximum stable arrival rate are derived for
the non saturated system and compared to a half-duplex counterpart, also
accounting for imperfect self-interference cancellation. This analysis better
identifies that the full-duplex advantage is prominent for sparse networks,
whereas in dense topologies residual self-interference may hinder achievable
gains.
