Today engineers have to generate a low cost and energy efficient TPMS tire units band to meet,
functionalities requirements, energy savings economical impact the TPMS architecture must have:
Emitted power:
at least +16dBm, corresponding to -13dBm/10 kHz power density to stay in the limits
imposed by normatives.
Energy efficient strategy:
to comply with 10 years expected lifetime the current consumption must be
of less than 500 nA.
Minimized mechanical:
Low weight and High robustness.
Integration optimization:
Integration for an easy installation and good logistic practicings:
Auto-location feature without complicate and expensive strategies
based accelerometers and/or LF (accelerometers and LF contribute on
reducing energy efficiency and usually have negative economical impact on
the target price of the wheel unit).
