Hierarchical Cellular Networks (HCN) provides an enhanced use of the indoor networks. These two lower layers called picocell and femtocell consist both high and low speed users. To prevent the dropping and blocking probabilities of ongoing calls in a network, cells are spitted into the small sizes. Although, many effective approaches are used but these delaying calls reach in a queue until a channel becomes available. In this paper, the authors propose M/M/C Markov model for two low layers of HCN having a FIFO queue in the femtocell layer and picocell layer, thereby comparing with a queue and without a queue. The effect of having a queue in the femtocell and picocell on both high and low speed users is observed.
