Fixed Wireless Access (FWA)
End-to-end flow for activating a residential Fixed Wireless Access broadband service, from RF coverage and cell capacity check through CPE self-install or technician-assisted outdoor antenna mounting, mobile core provisioning (HSS/PCRF on the same core as mobile handsets), dedicated FWA APN routing, TR-069 CPE configuration, data cap metering, and ongoing RF monitoring with cell capacity management. Demonstrates how the same CFS:BroadbandInternet used for FTTH decomposes to entirely different RFS items when the access technology is radio instead of fibre.
Architecture Overview
Fixed Wireless Access delivers residential broadband over 4G/5G radio instead of fibre. A CPE router with an embedded SIM connects to the nearest cell site, authenticates via the mobile core (HSS), and obtains IP connectivity through a dedicated FWA APN. The customer sees "broadband" — identical to FTTH from a service perspective — but the underlying access technology, capacity model, and assurance approach are fundamentally different. FWA shares cell capacity with mobile handset users, making capacity management the critical operational challenge.
Customer Premises
Home devices connect via Wi-Fi to the FWA CPE router. Indoor CPE sits on a window sill; outdoor CPE mounts externally with a directional antenna for better signal.
5G/4G CPE Router
Operator-supplied router with embedded SIM/eSIM. Contains 4G/5G modem, Wi-Fi AP, and Ethernet ports. Managed via TR-069 ACS. Band-lockable to optimise cell selection.
RAN (eNodeB / gNB)
4G eNodeB or 5G gNB serving the customer premises. FWA subscribers share PRBs (Physical Resource Blocks) with mobile handset users on the same cell. Capacity is finite and weather/load-dependent.
Mobile Core (EPC / 5GC)
HSS authenticates the CPE SIM. PGW/UPF routes FWA traffic via dedicated APN to BNG/NAT for internet breakout. PCRF/PCF enforces speed tier and data cap policies.
Services & Internet
BNG/CGNAT for internet breakout, TR-069 ACS for CPE management, billing/mediation with data cap metering, and cell capacity management for FWA subscriber gating.
