A modem encodes data to be sent by the radio transmitter and decodes data received by the radio receiver. A central processing is included. A direct signal connection is provided between the wireless interface device (114) and a keyboard (104). A baseband circuit encrypts data to be transmitted and decrypts received data. The wireless interface device has built-in scanning and decoding functions for an input device such as a keyboard (104) and a mouse (106). The wireless interface device (114) has power saving functions to extend the battery life of the input device. The wireless interface device (114) has the capability of automatically selecting between several communication frequencies or channels. The wireless interface device (114) has the capability of automatically selecting between several data rates.

Abstract: A computing system (100) wherein communication between a host computer (102) and peripheral units (104, 106), e.g. computer mouse (106) and keyboard (104), is performed using RF signals. The host computer (102) and the peripheral units (104, 106) each contain a transceiver for managing and transmitting the RF communication messages. An acknowledgement is sent by the receiving transceiver to the sending transceiver to signify that the message was successfully received. If no acknowledgement is received by the sending transceiver, a subsequent RF communication message is sent until an acknowledgement is received. A sleep mode is invoked between messages to conserve battery power in the peripheral units (104, 106), and the peripheral units (104, 106) send a report message to the host (102) when awaking periodically, or by a user command, from the sleep mode signifying that the peripheral unit (104, 106) is active and ready to send or receive messages.
