ARLA/CLUSTER: Experiencias entre 868MHz e 915MHz com 500mW através de transceptor em forma de USB stick

[João Costa > CT1FBF]

Open narrowband RF transceiver

No more restrictions from high level software! Access the lowest level
of radio transmission with this programmable USB stick.

DESCRIPTION

Project presents programmable RF transceiver in a form of USB stick.

Device is based around CC1120 radio with CC1190 front end. This combo
can put out 500mW at lowest bandwidth of 8kHz. Transceiver can operate
at 868MHz or 915MHz with WIDE variety of selectable properties. Radio
is controlled by STM32F051 microcontroller that is open for
programming.

Unlike closed transceiver sticks, this device allows you to :

- Carefully control frequency, bandwidth, deviation and bitrate to
achieve the best range in given environment.

- Select one of many modulations to fit your application, ranging from
simplistic OOK or ASK, through standard FSK/GFSK, to less common
spread spectrum, legacy analog or direct control of frequency offset.

- Integrate custom protocol or encryption into physical layer of data
transmission.

- Use received signal strength indicator (RSSI) for radio location or
analysis of reflections in given environment.
