Explore Cellular Networks from 2G to 5G
An interactive educational simulator that lets you visualize and understand the protocols, architectures, and security mechanisms behind every generation of mobile networks.
An interactive educational simulator that lets you visualize and understand the protocols, architectures, and security mechanisms behind every generation of mobile networks.
Simulate real network procedures across four generations of cellular standards.
Explore the 5G Core with AMF, SMF, UPF, and service-based architecture including network slicing concepts.
Step through EPC procedures—attach, handover, VoLTE calls—with eNodeB, MME, SGW, and PGW.
Visualize UTRAN signalling through NodeB, RNC, MSC, SGSN, and circuit-switched voice paths.
Understand the foundations of mobile networking with BTS, BSC, MSC, and GPRS data bearers.
Get up and running in three simple steps.
