In this hands-on lab you will construct the complete LTE architecture by dragging network elements into their correct positions and connecting them with the appropriate interfaces. You will place the UE, eNodeB, MME, Serving Gateway, PDN Gateway, HSS, and PCRF on a canvas, then draw S1-MME, S1-U, S5, S6a, S11, and Gx links between them. Each connection must match the correct protocol and plane, reinforcing the architecture you have studied throughout this module and building the spatial intuition that engineers rely on during real network design.
