Abstract: A long-range power-efficient multiple-band identification system and method includes, for example, a base-station control module and paired electronic key fob. The base-station control module and paired electronic key fob is arranged to provide a UHF (ultra-high frequency) wake transmitter for transmitting a wakeup signal in a UHF frequency range to the paired electronic key. When in range, the electronic key is awakened by the wakeup signal and in response transmits an acknowledgment reply to the base-station control module. After receiving the acknowledgment, the base-station control module transmits a relatively high power localization signal for determining an electronic key location.

Abstract: An electronic device and method for half duplex data transmission in a long range keyless entry and go system, and more specifically to an RFID transponder, a corresponding read/write (R/W) unit and methods for operating the RFID transponder and the R/W-unit. There is a first coil, a second coil and a third coil, being arranged as a three-dimensional antenna, a first capacitor, a second capacitor and a third capacitor couplable in parallel to the first coil, the second coil and the third coil, respectively, for selectively forming a first, a second and a third parallel-resonant circuit for receiving radio signals, a series-resonant circuit for transmitting radio signals and a control stage configured to either use one of the first, second or third parallel-resonant circuits for receiving radio signals or the series-resonant circuit for transmitting signals.
