Wireless Security Glossary
Fast definitions for the terms that appear across our troubleshooting and setup guides. Each entry is intentionally short and practical.
Wi-Fi terms
PMF / MFP
Protected Management Frames. A Wi-Fi control that protects some management frames from spoofing abuse.
WPA2-PSK
Common Wi-Fi security mode based on a shared passphrase and 4-way handshake.
WPA3-SAE
Modern Wi-Fi authentication scheme replacing WPA2-PSK behavior with stronger handshake properties.
BSSID
The AP radio MAC address. Useful when SSID names overlap or are hidden.
BLE terms
GATT
BLE data model composed of services and characteristics.
Pairing
Process that negotiates keys and security parameters.
Bonding
Storing negotiated keys so security context survives reconnects.
Characteristic permissions
Rules controlling whether reads/writes require encryption or authentication.
RFID/NFC terms
LF (125 kHz)
Low-frequency RFID commonly used in older proximity systems.
HF / NFC (13.56 MHz)
Higher-frequency ecosystem for NFC tags and many modern access cards.
UID
Tag identifier. Important for inventory, but not sufficient as a sole security control.
Sub-GHz / SDR terms
OOK
On-off keying modulation where presence/absence of carrier represents data.
FSK
Frequency-shift keying modulation that encodes data by shifting carrier frequency.
IQ samples
Complex baseband sample format used by SDR tools for analysis and decoding.
Front-end overload
Receiver saturation from strong signals; can create false peaks and unstable decodes.
