  • Patent number: 8717346
    Abstract: A low duty cycle wireless device is disclosed. The low duty cycle wireless device includes a high data rate transceiver, a low data rate receiver, and a microprocessor. The low data rate receiver receives a command to receive a large amount of information. The display information far exceeds the capacity for reception through the low data rate receiver. In response to the received command, the microprocessor wakes up from a sleep mode and activates the high data rate transceiver to receive the display information. The microprocessor deactivates the high data rate transceiver once the display information has been received.
