A transceiver which begins to power up the transmitter as soon as it is determined that a packet being received requires a response. A control circuit within the transceiver processes the packet as it is received to determine whether the packet requires a response. If it is determined that a response is necessary, the control circuit provides a control signal to the transmitter to power up the transmitter from a sleep mode even before the entire packet has been received and processed. The control circuit then continues to process the remainder of the packet as it is received while the transmitter powers up from the sleep mode. In this manner, the transmitter will become stabilized much earlier. Accordingly, the transceiver is able to respond more quickly than conventional devices and is thus able to increase response times and overall data exchange rates. Moreover, battery power of the transceiver is utilized more efficiently compared to devices which must continuously maintain the transmitter in a fully powered mode.

[ What is claimed is:] [1.] A transceiver apparatus, comprising:a receiver portion for receiving a packet of information, the packet comprising indicia for indicating whether the packet is to be responded to, and the indicia preceding at least one of control information and data also included in the packet;a transmitter portion for transmitting information, the transmitter portion being switchable, based on a control input, between a low power consumption mode and an active mode during which information is transmitted; anda control circuit coupled to the receiver portion for processing the packet received by the receiver portion to determine whether the packet is to be responded to wherein, prior to the receiver portion receiving the entire packet, the control circuit evaluates the indicia and provides the control input to the transmitter portion to initiate a switch of the transmitter portion from the low power consumption mode to the active mode in the event the packet is to be responded to,wherein the packet comprises a length field indicative of the length of the packet, and the control circuit compares the length of the packet to a predetermined criteria in connection with providing the control input to the transmitter portion.
