Current Product Range
Please refer to the individual datasheets on the VBOX Automotive website for our current telemetry radio range.
|Input voltage||6 to 30 V DC|
|Input current - Receiving||<50 mA|
|Input current - Transmitting||<200 mA|
|Radio transmission power||500 mW|

|Radio data rate||38400 kbit/s|
|RS232 data rate||115200 kbit/s|
The range of reliable transmission with a telemetry system depends on the antenna position and environment:
|Difficult environment (blocked by buildings or trees)||300 m (1000 ft)|
|Open environment with antennas at low level (clear view with antennas on car roofs)||700 m (2300 ft)|
|Open environment with antennas at height (clear view with antennas mounted on masts of building rooftops)||up to 3500 m (11000 ft)|
As an example of performance, Base Station telemetry communication range has been measured at distances of around 10000 m when the antennas were on hilltops with line of sight.
