RF (Radio Frequency)

Radio Frequency refers to the portion of the electromagnetic spectrum, roughly 3 kHz to 300 GHz, used for wireless communications. Mobile networks use specific licensed RF bands assigned by national regulators; security concerns include jamming (denial of service), eavesdropping (especially of unencrypted radio links), and rogue transmissions from unauthorised base stations.

RF 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 threats range from opportunistic SMS phishing and SIM swap to nation-state grade location tracking. The common thread is that most attacks exploit the inherited trust model of legacy signaling protocols.

To place RF in the wider telecom-security picture, review CVE, Cybersecurity, IoT, A5/0, A5/2 and A5/3 — each entry cross-references back to this page so you can walk the topic in either direction.
