Abstract:
1. A trainable transceiver for learning signal characteristics of an RF control signal received from a remote control transmitter used to remotely actuate a device and for subsequently transmitting a modulated RF signal having the learned signal characteristics, the trainable transceiver comprising: an antenna; a wideband receiver coupled to the antenna, the wideband receiver configured to receive an RF control signal from the remote control transmitter; and a control circuit coupled to the wideband receiver, the control circuit having a training mode in which the control circuit is configured to determine a device type associated with the RF control signal without first determining the frequency of transmission of the received RF control signal; wherein the control circuit is further configured to determine and store a plurality of possible frequencies, for future transmissions of the modulated RF signal from the trainable transceiver, based on the determined device type; and wherein the control circuit is configured to cause the transceiver to transmit new modulated RF signals based on the determined device type and the determined plurality of possible frequencies, and wherein the control circuit is configured to cause the transmissions to be sequential and to be sequenced such that commonly used frequencies of the plurality of possible frequencies are interspersed with less commonly used frequencies, wherein the control circuit is configured to use the sequential transmissions in a feedback-based process for determining whether a transmission has been successfully received by the device for remote actuation.
