Ultra-Reliable Low-Latency Communications have stringent delay constraints,\nand hence use codes with small block length (short codewords). In these cases,\nclassical models that provide good approximations to systems with infinitely\nlong codewords become imprecise. To remedy this, in this paper, an average\ncoding rate expression is derived for a large scale network with short\ncodewords using stochastic geometry and the theory of coding in the finite\nblocklength regime. The average coding rate and upper and lower bounds on the\noutage probability of the large-scale network are derived, and a tight\napproximation of the outage probability is presented. Then, simulations are\npresented to study the effect of network parameters on the average coding rate\nand the outage probability of the network, which demonstrate that results in\nthe literature derived for the infinite blocklength regime overestimate the\nnetwork performance, whereas the results in this paper provide a more realistic\nperformance evaluation.\n
