DS601-2
Range is dependant on many factors including
1. RF Power output
2. Receiver sensitivity
3. Antenna efficiency
4. Local environmental conditions and any local Interference
5. Data Type which is being transmitted.
Whilst items 1-4 are dependant on the system hardware design, item ‘5’ is equally important and often
overlooked. Given that there is a legal maximum power output which can be transmitted, and a limit on the
sensitivity of the receiver (usually constrained by cost), and that the antenna can never achieve 0dB loss
(100% efficiency), then the data structure and coding is an important aspect of the design.
The RF600T uses a fully balanced Manchester encoded data protocol designed for optimum use of the
radio transmission path. Manchester encoding enables the receiver ‘data slicer’ to maintain efficiency for
the duration of the data packet, (unlike many other encoder/decoder systems) which results in reduced bit
errors and therefore ensures maximum range.
Custom Versions
Customisation of the RF600T is available, please contact our sales department for further information.
