Description
3-channel coded digital wireless transmission
Perfectly reliable and widely proven, the SIGMA TRANSMISSION SYSTEM (STS) is the digital coded transmission system used on all our mid and high end wireless computer models for data transmission from the speed, cadence and heart rate transmitters. These collect the data from the sensor and send it in the form of data packets to the computer's built-in receiver.
The transmitter communicates with the computer in a question/answer format to ensure that the data sent has been received. The digital coding of the SIGMA TRANSMISSION SYSTEM protects the meter from data exchange with other users and from transmission interference.
