Updated Apr 8, 2026

A growing suite of tools for engineers working with cellular WAN connections — LTE, 5G, and hybrid failover deployments. Planned coverage includes RF signal quality reference (RSSI, RSRP, RSRQ, SINR thresholds), carrier APN and band reference, failover latency impact analysis, transaction-sensitive traffic profiling for ATM, POS, and branch banking, and diagnostic checklists for common cellular WAN degradation scenarios.

Built for network engineers at financial institutions, retail branches, and any site where cellular is the primary or failover WAN link.
