Fixed Wireless Access (FWA)

Fixed Wireless Access (FWA) 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.

Telecom networks depend on Internet-style routing (BGP, DNS, MPLS) for interconnect. Route hijacks and DNS abuse can degrade or intercept signaling, which is why RPKI and DNSSEC are now standard hardening for carrier networks.

To place Fixed Wireless Access (FWA) in the wider telecom-security picture, review Broadband, Last Mile, Handoff (Handover), Carrier Aggregation, 1G and 5GNR: each entry cross-references back to this page so you can walk the topic in either direction.
