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 the layer where mobile devices attach to the operator's infrastructure. Attacks in this layer include IMSI catching, rogue base stations, downgrade attacks and jamming, and defenses hinge 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 and lawful-interception abuse. The common thread is that most attacks exploit the inherited trust model of legacy signaling. SS7 and Diameter were designed for a closed operator community that no longer exists.

To place RF in the wider telecom-security picture, review IoT, RAN, GNSS, Jamming, TDMA and CVE.
