functional [@adhoc; @math]. Towards this end, let us introduce three stationary and isotropic processes: i) $ \Psi^{(1)} =\cup_{k\in \mathcal K} \Psi_k^{(1)}$, where $\Psi_{k}^{(1)}$ represents the PCP containing locations of type-$k$ transmitting nodes which are reusing radio resources with a similar code to the code[^3] of transmitter of interest; ii) $ \Psi^{(2)} =\cup_{k\in \mathcal K}  \Psi_k^{(2)}$, where $ \Psi_{k}^{(2)}$ represents the PCP containing locations of type-$k$ transmitting nodes which are reusing radio resources with a different code (or no code, in case $k\notin \phi$) than the transmitter of interest; and iii) $\Psi=\cup_{j\in\{1,2\}} \Psi_k^{(j)}$. For an AP located at the origin, the Laplace functional of the received interference at the receiver is given by: $$\begin{aligned}
 \mathcal L_{I_{\Psi}}(s)&=\mathbb E\big[\exp(-s I_{\Psi})\big]\label{base}\\
 &=\mathbb E\big[  \prod\nolimits_{j\in \{1,2\}} \prod\nolimits_{k\in \mathcal K}  \prod\nolimits_{{\bf x}\in \Psi_k^{(j)}}\mathcal L_h({sQ_j P_k  \text{g}({\bf x})})\big],\nonumber
  \end{aligned}$$ where $ Q_j P_k  \text{g}({\bf x})$ is the average received power due to a type-$k$ transmitter at point ${\bf x}$, $Q_1=1$, $Q_2=\mathcal Q$, and $\mathcal Q$ is the rate of rejection of interference between two devices with different multiple access codes, as defined in section \[sys\]. Also, $h$ is the power fading coefficient associated with the channel between the device and the AP, and $\mathcal L_{h}\big(s Q_j  P_k
