1.4 Understanding functions
In the following sections, all functions of (Q)Be© station are listed and described in detail, in
order to understand the operating principles of the system.
1.4.1 Micro.SP© technology
Direct TPMS systems utilizing traditional standard ASK or FSK modulation have several
limitations, the most important being the high energy consumption required by these systems
to transmit with acceptable efficiency. In battery-powered devices, this means that either
batteries need to be frequently replaced, or energy consumption must be lowered, thus
decreasing system performance.
Micro.SP© technology, patented by STE, is based on short RF pulses transmitted with Pulse
Position Modulation (PPM) technique, which guarantees high RF peak power, as required for
radio link reliability, but with a very low average power (Power Density) and consequently
