Introduction to Sub-GHz
Sub-GHz (sub-gigahertz) frequency refers to radio frequencies
that are below 1 gigahertz (GHz) on the electromagnetic
spectrum.
Many remote controls devices like garage door openers, car
key fobs, and other short-range communication devices
operate in the Sub-GHz frequency range.
Sub-GHz frequencies can provide better penetration through
obstacles like walls and have longer communication ranges
compared to higher frequency bands.
Introduction to Sub-GHz
Flipper Zero has an integrated multi-band antenna, and a CC1101
chip, making it a powerful transceiver with a range of up to 50
meters.
The CC1101 supports a wide range of frequencies in the Sub-
GHz range, typically from 300 MHz to 928 MHz.
Things Under Sub-GHz
Wireless Sensor Networks (WSN): Many wireless sensor networks,
particularly those designed for long-range communication in industrial
settings or environmental monitoring, may use frequencies in the Sub-
GHz range.
Internet of Things (IoT) Devices: Some IoT devices, especially those
requiring longer communication ranges, may operate in the sub-GHz
frequency range. This includes smart home devices, agricultural
sensors, and industrial IoT applications.
Things Under Sub-GHz
Amateur Radio: Certain amateur radio bands fall within the Sub-
GHz range. Amateur radio operators use these frequencies for
communication and experimentation.
Remote Controls: Some remote control systems, such as those
used for garage doors, car key fobs, and other short-range
communication devices, might operate in the Sub-GHz range.
Wireless Microphones: Certain wireless microphone systems
operate in the sub-GHz range.
Things Under Sub-GHz
Industrial Automation: Wireless communication in industrial
automation, such as for process control and monitoring, may use
frequencies in this range.
Smart Meters: Utility companies may use the Sub-GHz range for
smart meters that monitor and communicate information about
electricity, gas, or water usage.
