A communication protocol in a wireless network of a transceiver and a plurality of devices, in which at least one device is a bidirectional device, and in which one or more other devices can be unidirectional devices. The unidirectional device communicates with the transceiver in a unidirectional mode from the device to the transceiver and the bidirectional device communicates with the transceiver either in a bidirectional mode or in an unidirectional mode from the device to the transceiver. The communication protocol is configured to determine which transmission mode is to be used for each device. Various techniques are provided in order to optimize the time and energy spent to transmit information from one peer to the other.

Communication protocol for networked devices

One embodiment of the present invention provides a receiver for processing communication information included in transmissions received from a number of cordless devices. Another embodiment of the present invention provides a method for processing communication information included in transmissions received from a number of cordless devices. Another embodiment of the present invention provides a method for communicating status information from a cordless device to a corresponding driver running on a host system. Another embodiment of the present invention provides a method for processing digital information included in a transmission from a composite cordless device.

Multilink receiver for multiple cordless applications

A method and apparatus for securely connecting one or more wireless peripheral devices such as keyboards, mice, gamepads, remote controllers, joysticks and one or more host systems such as personal computers or workstations, the secure connection reducing the vulnerability of wireless communications between a wireless peripheral device and a host system to accidental or malicious interference or eavesdropping.
