Configuration & Planning Labs

Not quizzes — actual engineering tasks. Plan PCIs for a metro cluster, tune PRACH for a 22 km rural cell, architect S-NSSAI for a private enterprise network. A live rules engine scores your design against 3GPP like a real OSS would.

Slice Quota Allocation — fair sharing of 5GC capacity

Given 6 tenants on one 5GC, allocate NF instance quotas, PRB budgets, and session count limits so no tenant starves another during peak.

SSB Configuration — beam count vs coverage

Tune SSB periodicity, burst set size, and beam count for a stadium hotspot without blowing your PRB budget or breaking the inter-cell measurement contract.

Inter-RAT Neighbor Planning — LTE anchor for 5G NSA

Build the neighbour relation table for a 5G NSA rollout where LTE is the anchor. Get inter-RAT, inter-frequency, and X2 lists right so VoLTE fallback works.
