  In this letter, we characterize the performance of broadcast approach with
continuum of transmission layers in random wireless networks where the channel
state information (CSI) is assumed to be known only at the receiver. By
modeling the transmitter-receiver pairs using bipolar Poisson point process, we
derive analytical expressions for the mean and variance of achievable
transmission rate and the network transmission capacity under broadcast
approach. Our analysis shows that the broadcast approach provides better mean
transmission rate with lower variance compared to outage strategy.
