Capacity Planning

Capacity planning is the discipline of forecasting traffic demand and ensuring that compute, storage, transport, and radio resources are provisioned to meet it within agreed performance and availability targets. In mobile networks it spans radio (sites and spectrum), transport (backhaul and fronthaul), and core (signalling and user plane), and is increasingly automated with ML.

Capacity Planning in context

The radio access network is where mobile devices attach to the operator's infrastructure. Attacks in this layer include IMSI catching, rogue base stations and downgrade attacks; defenses rest on mutual authentication, integrity-protected signaling and Open RAN supply-chain hygiene.

The mobile core carries subscriber sessions, mobility and policy. In 4G it is the EPC (MME, HSS, S/PGW); in 5G it is the Service-Based Architecture with AMF, SMF, UPF, AUSF, UDM and the NRF.

To place Capacity Planning in the wider telecom-security picture, review User Plane Security, Base Station (BS), CAPEX, Interconnection, Man-in-the-Middle (MITM) and Mobile Network: each entry cross-references back to this page so you can walk the topic in either direction.
